What is photosynthesis GCSE definition?
Photosynthesis is the process by which plants make carbohydrates from raw materials, using energy from light. During photosynthesis: light energy is absorbed by chlorophyll – a green substance found in chloroplasts in the palisade cells in the leaf.
What is photosynthesis GCSE BBC Bitesize?
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules – carbon dioxide and water – using light energy.
What is photosynthesis in science Short answer?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What is photosynthesis full answer?
Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. Photosynthesis occurs in the chloroplasts in leaves (or other green tissues).
How does photosynthesis work ks3?
Photosynthesis takes place inside plant cells in small objects called chloroplasts . Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots. Light energy comes from the Sun. The oxygen produced is released into the air from the leaves.
What is photosynthesis ks3?
What is photosynthesis ks2?
Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Green plants use this light energy to change water and carbon dioxide into oxygen and nutrients called sugars.
What do you need to know about photosynthesis?
Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. Photosynthesis requires energy in the form of light to drive the chemical reaction. Photosynthesis is an endothermic reaction. The light energy required is absorbed by a green pigment called chlorophyll in the leaves.
How are glucose and oxygen produced in photosynthesis?
During photosynthesis, plants produce glucose and oxygen from carbon dioxide and water, using light energy from the Sun. \\ [ ext {carbon dioxide} + ext {water} \ghtarrow [chlorophyll] {light} ext {glucose}+ ext {oxygen}\\]
What happens to plant biomass as a result of photosynthesis?
Plant biomass will increase as a result of photosynthesis. During photosynthesis, plants produce glucose and oxygen from carbon dioxide and water, using light energy from the Sun. The following equations summarise what happens in photosynthesis:
How does light affect the rate of photosynthesis?
Green plants and algae use light energy to make glucose and oxygen from carbon dioxide and water. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.
