To intertwine scientific knowledge and practices and to empower students to learn through exploration, it is essential for scientific inquiry to be embedded in science education. In this unit, students will first develop an understanding of the biotic and abiotic factors within ecosystems, the characteristics and classification of living organisms, and how plants and animals obtain and use energy to fulfill their needs.
Then, students will delve deeper into the NGSS standards by examining the interdependent relationships within an ecosystem by studying movement of matter between producers, consumers, and decomposers by creating models of food chains and food webs.
At the end of this unit, students will study ways that individual communities can use science ideas to protect the Earth's resources and environment.
Today, I will open the lesson by completing yesterday's plant kingdom presentations. Students will then explore plant structures and plant needs. At the end of the lesson, students will reflect and apply their new understanding of plants by setting up an investigation on plant needs. Support an argument that plants get the materials they need for growth chiefly from air and water.
Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. Crosscutting Concept 6: Structure and Function. The energy released [from] food was once energy from the sun that was captured by plants in the chemical process that forms plant matter from air and water.
Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Organisms can survive only in environments in which their particular needs are met.
A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem. Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter gas, liquid, or solid back into the environment.
With science, it is often difficult to find a balance between providing students with as many hands-on experiences as possible, having plenty of science materials, and offering students a collaborative setting to solve problems.
Any time groups have four or more students, the opportunities for individual students to speak and take part in the exploration process decreases. With groups of two, I often struggle to find enough science materials to go around.
So this year, I chose to place students in teams of three! Picking science teams is always easy as I already have students placed in desk groups based upon behavior, abilities, and communication skills. Each desk group has about six kids, so I simply divide this larger group in half. To encourage a smooth running classroom, I ask students to decide who is a 1, 2, or 3 in their groups of three students without talking. In no time, each student has a number in the air.
I'll then ask the "threes" to get certain supplies, "ones" to grab their computers, and "twos" to hand out papers or whatever is needed for the lesson.If you have any doubts please refer to the Jntu Syllabus Book.

This process of the transport of water and minerals in over a long distance is carried out through the vascular system and is referred to as Translocation. Following mentioned are the different processes, which help in the transportation of water and nutrients in the plants:. Plants require water for different physiological activities, for example, providing fluidity to cells, acting as the medium for the occurrence of several biochemical reactions, and several others.
The terrestrial plants require a huge amount of water, to suffice for the phenomenon of transpiration. It is defined as the process, wherein the plants lose water from the leaves by the process of evaporation, in order to keep its body parts cool lower temperature.
In case a certain amount of solute is dissolved in the pure water, its potential decreases. This magnitude representing the decrease in the water potential of the pure water, as a result of solute dissolution, is referred to as S olute potential.
Osmosis : It is the process similar to that of diffusion, except that the movement of the substances in diffusion occurs across a semipermeable membrane. Plasmolysis : It refers to the shrinkage of the cell structure, as a result of the movement of water out of the cell.
This usually happens when a cell is placed in a Hypertonic medium. Imbibition : It describes a condition of diffusion, wherein the water molecules are absorbed by a certain solid substance, such as colloid. Further, as a result of absorption of the water molecule, the substance increases in its volume.
One common example is the absorption of water by seeds. The movement of the food and water in the plants is generally categorized as mass flow movement, wherein the substances are transported from one region to another region in masses.
The hydrostatic pressure, both positive and negative aids in the process of mass flow. Transpiration is the loss of water from the leaves of plants as a result of evaporation.Translocation : Transport of substances in plants over longer distances through the vascular tissue Xylem and Phloem is called translocation.
Means of transport : The transport of material into and out of the cells is carried out by a number of methods.
CBSE Class 11 Biology Revision Notes Chapter 5 - Morphology of Flowering Plants
These are diffusion, faciliated diffusion and active transport. Diffusion : Diffusion occurs from region of higher concentration to region of lower concentration across the permeable membrane. It is passive and slow process. No energy expenditure takes place. Facilitated diffusion : The diffusion of hydrophilic substances along the concentration gradient through fixed membrane transport protein without involving energy expenditure is called facilitated diffusion.
For this the membrane possess aquarporins and ion channels. No energy is utilized in this process. Active transport : Active transport is carried by the movable carrier proteins pumps of membrane. Active transport uses energy to pump molecules against a concentration gradient from a low concentration to high concentration uphill-transport. It is faster than passive transport.
Water potential : The chemical potential of water is called water potential. Osmosis is movement of solvent or water molecules from the region of their higher diffusion pressure or free energy to the region of their lower diffusion pressure or free energy across a semi-permeable membrane. Water molecules move from higher water potential to lower water potential until equilibrium is reached. Plasmolysis : Process of shrinkage of protoplasm in a cell due to exosmosis in hypertonic solution.
CBSE Class 12 Biology Revision Notes Chapter 2 - Sexual Reproduction in Flowering Plants
It is the tangential as well as radial walls of endodermal cells having the deposition of water impermeable suberin. Imbibition : Imbibition is the phenonmenon of adsorption of water or any other liquid by the solid particles of a substance without forming a solution.
Some examples of Imbibition : i If a dry piece of wood is placed in water, it swells and increases in its volume. Mass flow : Mass flow is the movement of substances water, minerals and food in bulk from one point to another as a result of pressure differences between two points. The transport of water to the tops of trees occurs through xylem vessels.
The forces of adhesion and cohesion maintain a thin and unbroken columns of water in the capillaries of xylem vessels through which it travesl upward. Water is mainly pulled by transpiration from leaves. Cohesion-tension-transpiration pull Model Root pressure : A hydrostatic pressure existing in roots which pushes the water up in xylem vessels.
Guttation : The water loss in its liquid phase at night and early morning through special openings of vein near the tip of leaves. Transpiration : The loss of water through stomata of leaves and other aerial parts of plants in form of water vapour.
Osomosis : Osmosis is movement of solvent or water molecules from the region of their higher diffusion pressure or free energy to the region of their lower diffusion pressure or free energy across a semi-permeable membrane. Casparian strip : It is the tangential as well as radial walls of endodermal cells having the deposition of water impermeable suberin. Please send your queries to ncerthelp gmail.

Till now, students would have studied this concept in previous classes but that was just a brief description. And now, you are going to learn in-depth and get a detailed idea about sexual reproduction in flowering plants. In this chapter, students will learn about certain new topics and sub-topics that include:. Flower- A fascinating organ of angiosperms.
Pre-fertilization: Structures and events. Double fertilization. Post-fertilization: Structures and events. Development and seed and fruits. Types of fruits. You are going to learn about morphology, process, and the structure of sexual reproduction in flowering plants, formation of seeds, fruits, endosperm, stamen, pollen grain, pistil, megasporangium, embryo sac, pollination, and a lot more. Well, Vedantu explains the complete chapter while covering every single topic explained in a very interactive manner.
It is carried on a stalk known as pedicel. Flower has an upper swollen region that is called receptacle. A usual angiosperm flower comprises 4 whorls of floral appendages which are attached on the receptacle- calyx, corolla, androecium, and gynoecium.
Calyx is the outer whorl of the flower that includes green sepals. Most of the sepals are green in color while some might resemble the color of the petals. This case is referred to as petaloid. The second whorl of a flower is corolla that comprises multiple petals. The third whorl of a flower is Androecium that acts as the male reproductive organ that comprises stamens. Gynoecium is the forth and innermost whorl of a flower that acts as the female reproductive organ of a flower.To browse Academia.
