Why does a plant need carbon dioxide for photosynthesis?

Why does a plant need carbon dioxide for photosynthesis?

Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. The carbon dioxide enters the leaves of the plant through small pores called stomata. During this process, the plant combines carbon dioxide with water to allow the plant to extract what it needs for food.

What do plants need to perform photosynthesis?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

What do plants do with most of the oxygen produced in photosynthesis?

Plants actually hold on to a small amount of the oxygen they produced in photosynthesis and use that oxygen to break down carbohydrates to give them energy.

Where does a plant get the carbon dioxide than it needs for the dark reaction of photosynthesis?

In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.

Where do plant get carbon dioxide from?

The Carbon Story. Plants absorb carbon dioxide through small openings called stomata that are on the surface of the leaf. If we zoom in on a plant leaf, so close that we can see the cells, we’ll find tiny openings called stomata

What is the end result of photosynthesis?

Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is a process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.

What is the main purpose of photosynthesis?

The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
