What is the process of photosynthesis GCSE?
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 AQA?
What is photosynthesis? The process by which plants synthesise glucose using light energy from the Sun. Light energy is converted into chemical energy.
How is energy for photosynthesis gained by plants GCSE?
During photosynthesis radiant energy from the sun (sunlight) is absorbed by green plants. The energy is used to convert carbon dioxide, water and minerals the plants take in from their surroundings into sugar and gaseous oxygen.
How do you calculate the rate of photosynthesis GCSE?
They varied the distance of the plant from the light source. In the table below, the Rate of photosynthesis = Number of bubbles produced per minute….Scientific calculations.
| Distance | Rate |
|---|---|
| 15 cm | 54 |
| 20 cm | 30 |
| 25 cm | 17 |
| 30 cm | 13 |
What is chlorophyll GCSE biology?
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.
What is photosynthesis UK?
Photosynthesis is a process that occurs in the leaves of a plant and needs both chlorophyll and light energy. During photosynthesis, the chlorophyll in leaves help convert carbon dioxide and water into the products oxygen and glucose.
Where does photosynthesis take place GCSE?
chloroplasts
Photosynthesis is an endothermic reaction. The light energy required is absorbed by a green pigment called chlorophyll in the leaves. Chlorophyll is located in chloroplasts in plant cells , particularly the palisade and spongy mesophyll cells .
How do plants make proteins GCSE?
Many glucose molecules are joined together to form insoluble cellulose. This is used to build cell walls for new growth. Glucose is joined with nitrates absorbed from the soil to make amino acids . These are joined together to make proteins during protein synthesis .
What is rate of photosynthesis?
The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds.
What topic is photosynthesis GCSE biology?
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.
