Question

List the internal factors that influence the rate of photosynthesis?

Answer 1

Answer:

Many external and internal factors affect the rate of photosynthesis. The external or environmental factors at:A light intensity, carbon dioxide concentration and temperature. The internal factor influencing the photosynthesis is chlorophyll content of the leaves and protoplasmic factors.

Answer 2

Dear Student,

◆ Photosynthesis -

• It is a process used by plants and other organisms to convert light energy into chemical energy.
• In photosynthesis plants take CO2 & water, convert it into glucose & O2 in presence of sunlight.

● Internal factors influencing rate of photosynthesis -

Chlorophyll -

• Absence of chlorophyll is limiting factor for photosynthesis.

Anatomy of leaf -

• Size, shape and location of stomata affect rate of photosynthesis.

Plant hormones -

• Auxin, cytokinin, gibberilins affect rate of photosynthesis.

Accumulation of products -

• Increase in conc of glucose and O2 in plant reduces rate of photosynthesis.

Thanks dear...
