Did anyone do this I need help will mark Brainliest

Explanation:

Stomata: as it allows the diffusion of carbon dioxide in the cell and oxygen out the cell.But it is held together by the guard cell.

Root hair cell:as this absorbs water and mineral ions efficently it does this by increasing surface area to absorb efficently and it ahs lots of mitochondria for the active transport of minerals ions from a dilute solution in the soil to a concentrated solution in the root hair

Xylem:This is spiral rings which are formed in a cell

cuz they cant breath

explanation:

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
