Animals and plants

It is how plants produce some of the nutrients they need to survive

carbon dioxide + water to oxygen + glucose

it was originally released by photosynthesis

it converts carbon dioxide and water into oxygen and glucose

it is the top layer of a leaf and it prevents water from excaping from the uppermost surface

the stoma are open pores which allow gas exchange with the environment, they can close when water is low to make sure photosynthesis can still happen

the spongy mesophyll is a layer of cells with air spaces so that gases can diffuse in and around the leaf

the palisade layer is a layer of tightly packed cells that are filled with chloroplasts, this makes sure that light is also absorobed and little can pass through

Increasing the temperature increases the rate of photosynthesis because more energy is provided. However, if the temperature is increased to above about 45°C, the enzymes that catalyse (speed-up) the reaction begin to denature (not work anymore). This causes the rate of the reaction to drop sharply until it stops altogether.

chlorophyll concentration gives a high rate of photosynthesis

Increasing the carbon dioxide concentration increases the rate of photosynthesis because carbon dioxide is a reactant in photosynthesis. However, above a certain threshold, further increases in the carbon dioxide concentration do not increase the rate of photosynthesis because another factor (such as light intensity) is limiting the rate of reaction.

Increasing light intensity increases the rate of photosynthesis because more energy is provided. However, if the light intensity is increased above a certain threshold, the rate of photosynthesis will not increase because another factor (such as temperature) is limiting the rate of the reaction.
