उत्तर
| Autotrophic nutrition | Heterotrophic nutrition |
| 1. It is the mode of nutrition in which organisms produce their own organic food. | It is the mode of nutrition in which organisms depend on other organisms for their food. |
| 2. Organisms producing their own food are known as autotrophs. | Organisms depending on others for food are known as heterotrophs. |
| 3. Autotrophs use simple inorganic substances present in the surroundings to produce food. | Heterotrophs depend on other organisms to get their food. |
| E.g. Plants | E.g. Fungi |

Name the following:
The pores through which leaves exchange gases.
Which part of the plant takes in carbon dioxide from the air for photosynthesis?
All animals and fungi are autotrophs.
List the steps of preparation of temporary mount of a leaf peel to observe stomata.

Name the following:
The cells which surround a stomatal pore.
What will happen to the rate of photosynthesis in a plant under the following circumstances?
Cloudy day in morning but bright sunshine in the afternoon.
Water absorption through roots can be increased by keeping the potted plants ______.
Name a gas produced in photosynthesis.
The Figure shown below represents an activity to prove the requirements for photosynthesis. During this activity, two healthy potted plants were kept in the dark for 72 hours. After 72 hours, KOH is kept in the watch glass in setup X and not in setup Y. Both these setups are air tight and have been kept in light for 6 hours. Then, Iodine Test is performed with one leaf from each of the two plants X and Y.
This experimental set up is used to prove essentiality of which of the following requirements of photosynthesis?
