Colorless particles are primary organelles and organelles are specially organized orbital organelles that contain starch, fat, and protein. Thus the cell base has a defensive plan. The particles are stored. These help the cells to perform various functions.
For example, in the internal arrangement of pigments, many membranes are involved in respiration, nourishment and removal of waste products or new layers are hanging in the material which is called stroma. The Outer Structure of Pigments The formation of proteins to particles. Thus, the cell is the basic constitutional unit of the organism. Are the same.

Like particles, pigments are also the basic functional unit of the organism itself. DNA and ribosomes are the basic unit of an organism 65
5.5 Discovered about the microscope. Discuss it with your teacher. Kano: Activity through the school library or the Internet Electron It only happens in living cells Dead cells What water do we get from this activity? Do not have the ability to absorb. The cell wall of plant cells as well as fungi and bacteria Co in the cell; And how do substances like water break down as well as carry outwards even though the cell wall is placed in a very slow external medium inside?

Not going. In such a medium the cells discuss water by aspiration. Has a tendency to get. As the cell swells, pressure builds up against the cell wall. Respective pressure against the cell wall swollen cell 2 Why the cell membrane produces selective penetrating Patel. Plant cells are animal cells due to the cell wall. Say? 3.2.2 The cell wall can withstand the maximum changes that occur in a medium outside of. In plant cells, apart from the cytoplasm, there is an extra bud covering on the outside of the 5.2.3 nucleus. Says the cell wall. The cell wall, the iodine solution root on the outer bark of the cell membrane, why? If we are on the side of the onion.

What if in a plant cell it should look mostly without putting a drop of iodine on the membrane? Try to be made of cellulose. Cellulose is a complex substance and see the difference. When we give a solution of iodine on the membrane gives the plants constitutional strength. Put, does each cell acquire color? When a living plant loses water through a figure, it differs from the cells according to their chemical composition. Some regions move away from other cell walls. This phenomenon is darker than plasmolysis regions. Known as the place of iodine solution. This phenomenon can be observed by using the following activity of a solution of saccharin or a solution of methylene blue. Activity 5.6 We observed cells from onions.

Let us now observe the cells of our body. Install the rhizome leaf bark (upper layer) on slide activity 5.7 and examine its cells under a microscope. Note the small green particles. Let's take a slide of glass. On what are called chloroplasts. Take a drop of water they contain green pigment. Gently rub the inside surface of the cheeks using an ice cream spoon. Called chlorophyll. Drops of concentrated solution of sugar or salt on the leaf established on the slide. Using a needle, we place this substance on a glass slide.
Pause for a minute and extend it under the microscope. Observe this slide ready for observation. What can we see? Curry. For color we will put a few drops of methylene blue on it now a few riho leaves in boiled water. Now place the mass under the microscope for minutes. This destroys the cells. Then ready for observation.

After placing the coverslip on it, place a drop of a concentrated solution of sugar or salt on the leaf placed on the slide. What will we observe? What form of cells do we see? Draw it on the observation sheet. 1 Don't forget! .. that! Pause for minutes and review again. What will we see? What will happen now? 61 The basic unit of an organism is .
