Assertion: The external factors that affect
photosynthesis are number, size, age and
orientation of leaves, mesophyll cells and
chloroplasts and the amount of chlorophyll.
Reason: The internal factors that affect
photosynthesis are availability of sunlight,
temperature,
concentration and water.
photosynthesis are number, size, age and
orientation of leaves, mesophyll cells and
chloroplasts and the amount of chlorophyll.
Reason: The internal factors that affect
photosynthesis are availability of sunlight,
temperature,
concentration and water.
View answer and explanation
