How does plants make their own food

It also takes up water from its roots and carbon dioxide gas from the air. The plant uses the glucose as a food to help it stay alive and grow. Water rises up through the stem. It carries nutrients that keep the plant healthy. The water also keeps the whole plant firm and upright. Without enough water, the plant goes floppy, or wilts.

Great ideas on how your garden, or even a small backyard or balcony, can become a mini nature reserve. This fantastic wetland site is located north of Southport town centre and has some of the best wildlife in the region. Without plants, birds and other animals would have nothing to eat. In fact, without plants there would be no life on Earth at all. Think about this next time you see somebody pulling up a thistle or chopping down a tree!

Plants are called producers because they make — or produce — their own food. Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide CO2 from the air. They convert these ingredients into food by using energy from sunlight. The foods are called glucose and starch. A few plants can grab an extra meal by eating small animals. The sundew lives in boggy areas, where the acid soil is poor in minerals.

Sticky tentacles on its leaves trap any small insect that lands on them. The insect dies, and the sundew gradually absorbs its juices to get a special mineral supplement. Even so, most of the growth that sundews make comes directly from photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen O 2 and chemical energy stored in glucose a sugar.

Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores. During photosynthesis, plants take in carbon dioxide CO 2 and water H 2 O 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. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.

During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green. While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.

The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light- dependent reaction. The light-independent stage, also known as the Calvin Cycle , takes place in the stroma , the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light- independent reaction. C3 and C4 photosynthesis. Not all forms of photosynthesis are created equal, however.

There are different types of photosynthesis, including C3 photosynthesis and C4 photosynthesis. C3 photosynthesis is used by the majority of plants. It involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become glucose. C4 photosynthesis, on the other hand, produces a four-carbon intermediate compound, which splits into carbon dioxide and a three-carbon compound during the Calvin Cycle.

A benefit of C4 photosynthesis is that by producing higher levels of carbon, it allows plants to thrive in environments without much light or water. Used by the majority of plants, it involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become a sugar called glucose.

Involves producing a four-carbon intermediate compound, which splits into carbon dioxide and a three-carbon compound during the Calvin Cycle in plants that do not get a lot of light or water.
