Flashcards in B2.2- Ecosystem Process Deck (14)
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?
What is a nitrate deficiency?
Poor growth and yellow leaves
What are phosphates used for?
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?
What is a magnesium deficiency?
Describe the process of photosynthesis
Some species of bacteria use a range of chemical reactions to create glucose. No word equation but:
• source of energy=chemicals
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
