Explanation / Answer

47. Acoelomates are characterized by a solid body without a cavity surrounding the internal organs.

·         Coelom that is not completely lined with mesoderm is called pseudocoelom.

·         Deuterostome development is a character of enterocoelomates.

·         In acoelomates, the blastocoel is entirely occupied by the mesoderm.

Therefore, option E is correct.

48. Transpiration in plants requires the following processes like

Therefore, all are required except option D.

49. in insects,

Therefore, option A is correct.

50. Nitrogen, potassium, and calcium enter the plant as ions from the soil.

Water also enters the plants through roots only.

But, carbon dioxide is absorbed by the plants from air.

Therefore, option A is correct.
