Question

factors affecting photosynthesis?​

Answer 1

Answer:

the rate of oxygen output

the rate of carbon dioxide uptake

the rate of carbohydrate (glucose) production

These are not perfect methods as the plant will also be respiring, which will use up some oxygen and carbohydrate and increase carbon dioxide output.

Several factors can affect the rate of photosynthesis:

light intensity

carbon dioxide concentration

temperature

The amount of chlorophyll also affects the rate of photosynthesis:

plants in lighting conditions unfavourable for photosynthesis synthesise more chlorophyll, to absorb the light required

the effects of some plant diseases affect the amount of chlorophyll, and therefore the ability of a plant to photosynthesise, such as downy mildew in grape vines

Answer 2

Question ⤵

Factors affecting photosynthesis?

Answer ⤵

There are several factors which affect the rate of photosynthesis like light, temperature, carbon dioxide,water and chlorophyll. All these factors are interdependent and the rate of photosynthesis gets affected if there is a change in any of these factors.

Explanation ⤵

In order to perform, a leaf requires the following things.

• Carbon Dioxide
• Water
• Sunlight
• Chlorophyll
