Question

TRUE OR FALSE? Please make sure you state why it is true or false.

1. Gases travel into and out of plant leaves through pores called storma.

2. Mesophyll cells acquire the water required for photosynthesis by absorbing it from the humid atmosphere.

3. Carbon fixation occurs in both photosynthesis and cell respiration.

4. Plants store sugars made during photosynthesis is cellulose, a polysaccharide which serves as the storage form of carbohydrates fuel.

Answer 1

1. The statatemnt is FALSE that the Gases travel into and out of plant leaves through pores called storma.

Gaseous exchange amd water exchange in the plants occur by the tiny pores known as Stomata which are the kidney shaped cells present in the epidermis.

2. The statement is FALSE that the
Mesophyll cells acquire the water required for photosynthesis by absorbing it from the humid atmosphere.
Water is being stored in the large vacuole which stores up 90% of the plant water after bring absorbed by the roots from the soil.

3. The statement is FALSE that Carbon fixation occurs in both photosynthesis and cell respiration.

Because carbon fixation occurs during C3 cycle when the inorganic molecules are converted to the organic molecules by plants and certain other living organisms like blue green algae, bacteria etc.

4. The statement is FALSE that the Plants store sugars made during photosynthesis is cellulose, a polysaccharide which serves as the storage form of carbohydrates fuel.

Because the storage form of carbohydrates in plants is the STARCH which is A polysaccharide.
