How do plants turn sugar into energy?

How do plants turn sugar into energy?

In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.

What process breaks down sugar into energy?

Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP.

Why do plants break down sugars?

Plants break down sugar to energy using the same processes that we do. Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive. (They use the ‘carbon’ in carbon dioxide to build the sugar molecule).

How do plants get sugar?

Plants produce sugar and oxygen in a process called photosynthesis, by using sunlight, water, and carbon dioxide. In a two-step process, plants obtain chemical energy from sunlight. The collected energy is used in a second reaction to produce the sugar glucose.

Do plants break down glucose to obtain energy?

Plants such as ferns need to breakdown glucose to obtain energy. This is because they make glucose and break it down to produce ATP. During the day they use light energy from the sun to make glucose from carbon dioxide and water. That glucose is then broken down by a process called cellular respiration.

How do plants absorb sugar?

Plants have chlorophyll that uses sunlight to gather energy. The energy is then used to change carbon dioxide from the air into sugars like glucose and fructose. The plants then load the sugars from the leaves into the phloem in preparation for transport to other areas of the plant.

What happens to the sugar molecules in photosynthesis?

Through photosynthesis, plants create sugar molecules that store energy for them to use later. Some of the sugar molecules become part of the structure of the plant in the form of cellulose. Have students discuss with a partner what they think plants need in order to do photosynthesis.

How are plants able to get energy from food?

This is the process that plants use to get energy (whereas humans and other animals get energy by eating food). Through photosynthesis, plants create sugar molecules that store energy for them to use later. Some of the sugar molecules become part of the structure of the plant in the form of cellulose.

What happens to carbon when it leaves a plant?

Four things can happen to move carbon from a plant and return it to the atmosphere, but all involve the same chemical reaction. Plants break down the sugar to get the energy they need to grow. Animals (including people) eat the plants or plankton, and break down the plant sugar to get energy.
