Question

. Differentiate between-
a- Grana and Thylakoid
b- Xylem and Phloem
pls it contains 15 points

Answer 1

Difference between Xylem and Phloem. The plants absorb nutrients by the roots in the soil for their nourishment. The nutrients and water, sugar substances are transported from the roots to all the parts of the plant by the tissues called xylem and phloem.

Answer 2

hey mate
here is your answer

●xylem conduct water and Minerals .
》phloem conduct organic solutes are food materials.

●in xylem conduction is mostly unidirectional i.e., from root to apical parts of the plant .
》in phloem conduction maybe bidirectional i.e.,from leaves to storage organs or growing parts or from storage organs to growing parts of the plant .

●in xylem conducting channels are tercheary elements are tracheids and vessels .
》in phloem conducting channels are sieve tubes.

●components of xylem include tracheids, vessels, xylem parenchyma and xylem fibres.
》components of phloem include sieve tubes, companion cell, phloem parenchyma and phloem fibres.

●in addition to conduction ,xylem provides mechanical strength to the plant .
》 phloem perform no mechanical function for the plants .

hope it's help you ☺☺
