Question

Identify four factors that could affect the rate of photosynthesis in plants.

a) Light intensity, temperature, carbon dioxide concentration, and water availability
b) Soil pH, leaf color, humidity, and wind speed
c) Plant age, soil type, air pressure, and leaf size
d) Pest infestation, root length, plant height, and rainfall

Answer 1

The four factors that could affect the rate of photosynthesis in plants are light intensity, temperature, carbon dioxide concentration, and water availability.

Step-by-step explanation:

The four factors that could affect the rate of photosynthesis in plants are:

1. Light intensity: Without light, photosynthesis cannot occur. Too much light can also be harmful for plants.
2. Temperature: Plants have an optimal temperature range for photosynthesis. Extremes in temperature can negatively affect photosynthesis.
3. Carbon dioxide concentration: Adequate levels of CO2 are necessary for photosynthesis. A lack of CO2 can limit the rate of photosynthesis.
4. Water availability: Water is essential for photosynthesis and overall plant growth. Both water deficiency and waterlogged soil can impact photosynthesis.
