- Plants and crops are living organisms.
- Crops are specific plants that are grown in a vegetable patch, allotment or field.
- Plants and crops need certain conditions in order to grow.
What Do Plants And Crops Need To Grow?
- Carbon Dioxide (CO2)
- Water (H2O)
- Correct Temperature
Plants and crops absorb water (H2O) through their roots.
This water (H2O) absorption is the means by which plants and crops gather nutrients from the soil.
Temperature can affect the levels of water (H2O) absorption and nutrient intake.
Photosynthesis it the process by which plants and crops make their food using sunlight, water (H2O) and carbon dioxide (CO2).
Photosynthesis takes place in the leaf cells (chloroplasts).
The leaf cells (chloroplasts) contain a green pigment (chlorophyll) that absorbs energy from the sunlight.
Carbon dioxide (CO2) in the air enters the leaves through the leaves (stomata).
This intake of carbon dioxide (CO2) is called respiration.
The absorbed energy (sunlight) is used to break up the carbon dioxide (CO2) and water (H2O) molecules to produce sugar glucose and oxygen (O2).
The sugar feeds the plants and crops and helps them to grow.
The system of veins in the leaves and stem allows the sugar glucose to travel to all parts of the plants and crops.
Oxygen (O2) is also produced during photosynthesis.
Oxygen (O2) is a waste product and is released into the air via the leaves (stomata).
This release of oxygen (O2) is known as respiration.
