Answers
Explanation:
A Xylem- (i) It helps in transportation of water and minerals through only upwards.
(ii) Xylem fiber is dead.
Pholem- (i) It helps in transportation of foods and organic materials through bidirectional.
(ii) Phloem fiber is also dead.
B
Parenchyma - (i) it has intercellular spaces.
(ii)it store food and helps in photosynthesis.
Collenchyma- (i) it provide flexibility to the plants.
(ii) It has more intercellular spaces.
Answer:
Difference between xylem and phloem tissue
Xylem tissue - Xylem tissues are found in leaves roots and stem . Xylem tissue is composed of xylem vessels , fibers , and trachieds .
Phloem tissue - Phloem tissues are found in stems and leaves which later grow in the roots , fruits and seeds.Phloem tissue is composed of like sieve tubes, companion cells , phloem fibers and phloem parenchyma .
Difference between Parenchyma and collenchyma
Parenchyma - Parenchyma cells are involved in photosynthesis , storage, and secretion .
Collenchyma - Collenchyma cells are involved in support and transportation of nutrients .
