Question

select the correct statement.

a, More number of chloroplast are seen on the lower surface of leaves.

b, During photosynthesis, oxygen is evolved from carbon dioxide.

c, Glucose is stored as starch in leaves.




Which is the correct answer. Find it ​

Answer 1

The correct statement is a) More chloroplast are seen on the lower surface of leaves.

Explanation:

• The leaf mesophyll is composed of parenchyma tissue. The elongated palisade parenchyma contains the largest number of chloroplasts and is the primary site of photosynthesis in many plants.
• The majority of chloroplasts are found in the plant's leaves because these structures have the greatest surface area for absorption.
• Oxygen evolves in the process of photosynthesis by photolysis of water that occurs in membranes of grana thylakoids.
• The oxygen that evolved during photosynthesis comes from water molecules.
• Starch is stored in the stroma of the chloroplasts and the cytoplasm of leaves.
• The excess glucose is stored as starch in different plant parts, including roots and seeds.

Answer 2

Glucose is stored as starch in leaves this statement is the correct statement.

Explanation:

• Option C. Glucose is stored as starch in leaves is the correct statement.
• During the photosynthesis process, a plant's leaves produce sugar.
• The sun's energy is used to provide power to the facility.
• So, on a bright day, when plants make sugar (for fuel, energy), they store some of it as starch. Green plants glycogen in their leaves.
• They generate sugar during the photosynthesis process, therefore they store a few of the sugar/glucose (energy) they obtain from of the sun as starch.
• Option A. More number of chloroplast are seen on the lower surface of leaves is incorrect statement.
• In many plants, the elongated palisade parenchyma contains the most chloroplasts per cell and is the major location of photosynthesis.
• Between the upper and lower epidermis is the mesophyll (ground tissue).
• Mesophyll cells are found in the leaves of the plant.
• We find the palisade parenchyma cells of the mesophyll.
• Option B. During photosynthesis, oxygen is evolved from carbon dioxide is incorrect statement.
• During photosynthesis, process known as photosynthesis (CO2) and water (H2O) from the surrounding air.
• Freshwater is oxygenated in the plant tissues, which means it loses electrons, but carbon dioxide is reduced, which means it receives electrons.
• Water is converted to oxygen, while carbon dioxide is converted to glucose.
• Photosynthesis is a redox reaction that involves the reduction of carbon dioxide to sugars and the oxidation of water to liberate oxygen.
