Plant nutrients Flashcards
What is photosynthesis
A chemical process where plants and algae use energy from sunlight to make glucose
Wheat is the equation for photosynthesis
Carbon dioxide + water arrow glucose + oxygen
What four things are needed for photosynthesis
Sun
Water
Chlorophyll
Carbon dioxide
What is chlorophyll
A green chemical in chloroplasts which absorbs sunlight
What is the 1st adaptation for photosynthesis
A big surface area for absorbing light
What is the 2nd adaption for photosynthesis in leaves
Chloroplasts mostly near the top of leaves for more light
What is the 3rd adaptation for photosynthesis
Vines to deliver water to cells and take glucose away
What is the 4th adaptation for photosynthesis
Stomata
What are stomata used for
Small holes for gas exchange
What do roots absorb
Minerals and water
Where do plants get minerals from
Soil
Why do they need minerals
To stay healthy and for processes like photosynthesis and respiration
What minerals can fertilisers contain
Nitrates phosphates and potassium compound
What mineral is supplied by nitrate
NITROGEN
Why is nitrogen needed
To make amino acids for protiens
Why is protein needed in plants
For cell growth
What mineral does phosphorus supply
Phosphates
Why is phosphorus needed
To make DNA and cell membranes
What mineral does Potassium,k make
Potassium compounds
Why is potassium needed
It is needed in enzymes involved in respiration and photosynthesis
