Why do plants need water sunlight and carbon dioxide?

Why do plants need water sunlight and carbon dioxide?

Photosynthesis is a wondrous and yet simple chemical reaction that occurs when plants use sunlight, water and carbon dioxide to make energy-packed food molecules. Plants pull water from their roots and absorb molecules of atmospheric carbon dioxide to gather the necessary ingredients for synthesizing glucose (sugar).

Which process in a plant uses CO2?

Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Why do plant cells need sunlight and water?

Well, sunlight is energy and photosynthesis is the process plants use to take the energy from sunlight and use it to convert carbon dioxide and water into food. Plants need three basic things to live: water, sunlight, and carbon dioxide. When plants breathe carbon dioxide in, they breathe out oxygen.

What is the role of carbon dioxide and water in the process of photosynthesis?

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. 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.

Why sunlight is necessary for photosynthesis?

Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

Why is co2 needed in photosynthesis?

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.

How do plants get the carbon dioxide they need for photosynthesis?

Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata . These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.

What is the role of carbon dioxide and water in the?

Carbon dioxide plays an important part in vital plant and animal process, such as photosynthesis and respiration. Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. This process is called photosynthesis.

What is the role of carbon dioxide and water in the process of photosynthesis Class 7?

Carbon dioxide + Water → Glucose + Oxygen The process of photosynthesis takes place in the leaves of a plant. Oxygen gas is produced during photosynthesis which is utilised by all the living organisms for their survival. (1) The process of photosynthesis first produces a simple carbohydrate called ‘glucose’ as food.

Why is sunlight important for plants?

Why Do Plants Need Sunlight to Grow? Without getting too deep into the science, sun-light is a key energy source for all plants. Through a process called photosynthesis, plants absorb energy from the sun, which fuels the processes necessary for survival.
