B2.2- Ecosystem Process Flashcards
What is the word equation for photosynthesis?
Carbon dioxide + water- light- oxygen + glucose + water
How is the lead adapted to increase photosynthesis?
- large surface area- to absorb more light
- thin- shorter distance for gas to diffuse in and out
- chlorophyll- make leaf green and used in photosynthesis
- network of veins to support leaf and transport water and carbohydrase
- stomata- for gas to diffuse in and out
What are nitrates used for?
Healthy growth
What is a nitrate deficiency?
Poor growth and yellow leaves
What are phosphates used for?
Healthy roots
What is a phosphate deficiency?
Poor root growth and purple leaves
What is potassium used for?
Healthy leaves and flowers
What is a potassium deficiency?
Yellow leaves and dead patches
What is magnesium used for?
Making chlorophyll
What is a magnesium deficiency?
Yellow leaves
Describe the process of photosynthesis
Some species of bacteria use a range of chemical reactions to create glucose. No word equation but:
• reactant=co2
• source of energy=chemicals
•product=glucose
It happens when light can’t be used to create energy
What is the word equation of aerobic respiration?
Glucose + oxygen = carbon dioxide + water + energy
Where does aerobic respiration occur?
In the mitochondria
What is the word equation for anerobic respiration?
Glucose = lactic acid
