Easy!
What are the tiny pores on a leaf's surface?
Stomata
Why does the stomata open and close?
This is to control gas exchange and water loss
What is the percentage of Bb? (heterozygous/hybrid)
50%
What are the special pair of cells that borders the tiny pores of the stomata called?
Guard cells
This helps cool the plant, which is similar to sweating for humans. What process is this?
Transpiration
What is the fastest transpiration rate?
High temperature + low humidity + bright light
When does the guard cells change their shape?
When they open or close their opening
What happens when the stomata stays close for too long?
Photosynthesis slows down, but water is conserved
What's the difference between the phenotype ratio and the genotype ratio?
G = it countd the internal gene makeup, such as homozygous dominant, heterozygous, or homozygous recessive (ex: 1 : 2 : 1)
P = it counts external visible expressions of those genes, which are also influenced by dominance and the environment (ex: 3 : 1)
What is the percentage of each punnet square?
25%
It maximizes water storage: thick cuticles to reduce water loss
Dessert
Why do they let carbon dioxide (co2) enter the leaf?
It is for photosynthesis and to release oxygen into the atmosphere
When does the stomata open and close?
They open during the day, and close at night/hot hours
This means more water equals to broader leaves
Rainforest
What is homozygous?
Means having inherited two identical alleles of a particular gene, one from each biogical parent
