Question

Question 19 options:

	Reduced leaves, succulent leaves, short-lived annuals
	Large spreading leaves, epiphyitc habit, lianas
	stunted small plants with perrenial habits
	grasses, thorny trees, epiphytic habit

In the life cycle of mosses, which of the following is true?

Question 16 options:

	The gametophyte is microscopic and dependent on the sprorophyte
	The gametophyte and sporophyte are both free-living multicellular organisms
	The sporophytic generation is very noticable, is green, and performs photosynthesis
	The sporophytic generation grows out of gametophytic tissue and is dependent on the green gametophyte for nutrition

Which of the following do early-evolved land plants NOT share with their aquatic ancestors?

Question 15 options:

	Cell walls
	sperm ultrastructure, haploid dominant lifecycle
	waxy cuticle
	Photosynthetic pigments (e.g. Chlorophyll, carotenoids)

Answer 1

Q19. plants in tropical rainforests are small and widely spaced due to less sunlight. leaves are large, epiphytes such as mosses, ferns, and lichens are commonly found, option B is correct- Large spreading leaves, epiphyitc habit, lianas

Q16. The sporophytic generation grows out of gametophytic tissue and is dependent on the green gametophyte for nutrition. In bryophytes, the gametophyte is dominant and sporophyte is dependent on it.

Q15. waxy cuticle was absent in aquatic plant, also vascular system evolved in land plants for water transport.
