Explanation / Answer

Answer:

44.

Compound eyes are composed of the individual visual units known as ommatidia.

Hence, option (C) is correct answer.

45.

Plasmodesmata are found between sieve tubes and companion cells.

Hence,option (a,b) are correct.

46.

Phloem are the vescular tissues that distribute sugar throughout the plants.

Hence, option (B) is correct answer.

47.

Active transport through xylem vessels is not required in transpiration in plants.

Hence, option (d) is correct answer.

48.

Procaryotes support growth of the plants by fixing nitrogen.

Hence,option (a) is true.

49.

Transportational pull is primarymechanismthat transport water to leaves.

Hence, option (B) is correct answer.

50.

Halophile can be found in stromatolites.

Hence,option (e) is correct.
