$\mathfrak{\huge{\green{\underline{\underline{Answer }}}}}$

Functions of stomata

• Stomata are present on the surface of leaves and have two guard cells which ensure their closening & opening.
• These allows entry of Co2 from environment and release of O2 in the atmosphere.
• These also check transpiration.

Answer 2

Answer:

1. The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs.

2. Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

3. Without the green chlorophyll all plants would be white. It doesn't make food for itself like other plants, but instead gets its nourishment through a mutually beneficial fungal and tree root (mycorrhizal) relationship. Ultimately it gets nourishment from the trees.

4. The hot water kills the leaf and the alcohol breaks down the chlorophyll, taking the green color out of the leaf. When you put iodine on the leaves, one of them will turn blue-black and the other will be a reddish-brown. Iodine is an indicator that turns blue-black in the presence of starch.

5. This energy comes from the sun. Plants make their food from energy from the sun. Animals get their energy from the food they eat. ... This passing of energy from the sun to plants to animals to other animals is called a food chain.

6. The balance of the plants and animals have brought a change to the earth. ... Plants by photosynthesis and animals by respiration, by which the two get benefited in one or the other way. ... When theplants and animals in an area are kept in balance, this preserves biodiversity.
