The major function of leaves is to

a make food
b store food
c transport
d absorb nutrients

The answer should be A, make food.

A lot of chloroplasts are found in leaves because that is the location where photosynthesis occurs, the process that a plant makes food (glucose) for themselves by using sunlight, carbon dioxide from the atmosphere, and water.

On the other hand, plants usually store food in places such as seeds or underground stems.

Transport should mainly occur in the stem, where there's xylem and phloem. Xylem is for transporting water and mineral ions while phloem is for transporting amino acids or food the plant made from photosynthesis.

Last but not least, nutrients are usually absorbed from the root, by the root hair cells. They absorb water and mineral ions from the soil and are transported to the leaves or anywhere else needed.

the cytokine-activated janus kinase (jak)-signal transducer and activator of transcription (stat) pathway has an important role in the control of immune responses. dysregulation of jak-stat signaling is associated with various immune disorders.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
