Answer
1. Name the process by which plants make 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. This process is called photosynthesis, which means 'making out of light'. The foods are called glucose and starch.
2. Name the part of a plant which produces its food.
Leaves because it contains chlorophyll which is the green pigment and leaves makes food with the help of sunlight, water, carbon dioxide and this process is called photosynthesis.
3. What substance in the leaves gives them a green colour?
Chlorophyll
Plants use glucose together with nutrients taken from the soil to make new leaves and other plant parts. The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light.
4. What is the main vein of a leaf known as ?
midrib
In pinnately veined leaves the central vein in known as the midrib.
5. Six Name the green pigment present in the leaves of a plant.
Chlorophyll
Chlorophyll is the primary pigment in plants; it is a chlorin that absorbs yellow and blue wavelengths of light while reflecting green. It is the presence and relative abundance of chlorophyll that gives plants their green color.
6. Name a gas used in photosynthesis.
carbon dioxide
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
7. Name a gas produced in photosynthesis.
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.
8. Name the process by which plant leaves lose water into
iTranspiration: The release of water from plant leaves
Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration
9. Which substance is used to remove chlorophyll from a gre
Alcohol is used to remove chlorophyll from a green leaf during photosynthesis experiments.
10. Name the two substances which combine in green leaves
Carbon dioxide And Chlorophyll present in chroloplast combines in the presence of sunlight to make food.
