Factors affecting Photosynthesis

Write a note on the water as a limiting factor of photosynthesis.

Water stress reduces the rate of photosynthesis.

Water stress checks the diffusion of CO₂ required for photosynthesis.

Fill in the blank with the correct answer from the bracket.

Under water stress, the _____ are closed. (stomata, phloem, xylem) 

Explain the role of phytohormones in photosynthesis.

Which of the following is not an internal factor that has role in photosynthesis?

What are the internal factors that affect photosynthesis.

Age of _____ (leaves/stem) plays an important role in photosynthesis.

The chlorophyll content has no role in photosynthesis.

Suppose Euphorbia and Maize are grown in the tropical area. Which one of them do you think will be able to survive under such conditions?

Which of the following factors is not a limiting factor for photosynthesis?

Give a detailed explanation of factors affecting photosynthesis.

What is the contribution of Blackman in plant physiology?

What is the rule of limiting factor?

Fill in the blank with the correction option from the bracket.

_____refers to the intensity of light at which the rate of respiration is equal to that of photosynthesis. (Compensation point, Condensation point, Dew point)

Which of the following would not limit photosynthesis?

The diagram below shows three plants with identical leaf surface areas:


Assuming all other conditions were identical for all three plants, which of the plants would likely to photosynthesize slowest and fastest.

When $NaHC{O}_3$ is added in small quantity in an experiment showing photosynthesis, what will be the effect on it

The algae found in high temperature ponds are capable of doing photosynthesis upto

Assertion : The atmospheric concentration of $C{O}_2$ at which photosynthesis just compensates for respiration is referred to as $C{O}_2$ compensation point.

Reason : The $C{O}_2$ compensation point is reached when the amount of $C{O}_2$ uptake is less than that generated through respiration because the level of $C{O}_2$ in the atmosphere is more than that required for achieving $C{O}_2$ compensation point.
