The rate of photosynthesis can be measured indirectly by monitoring oxygen production using a dissolved oxygen sensor or by measuring the accumulation of glucose through chemical assays.

If sunlight is essential for photosynthesis, the plants exposed to sunlight should exhibit a noticeable increase in oxygen production or glucose accumulation compared to those kept in darkness.

Place potted plants of the same species in two groups, ensuring they receive identical amounts of water and nutrients. One group should be placed in a well-lit area where they can receive sunlight, while the other group should be placed ...

An experiment could involve placing identical plants in two separate environments: one exposed to sunlight and the other kept in darkness. By measuring the rate of oxygen production or glucose accumulation in each plant, we can determine whether sunlight is ...

Guard cells surround each stomatal pore and control its opening and closing. When guard cells absorb water, they swell and the stomatal pore opens. Conversely, when they lose water, they shrink, causing the pore to close.
