Students have asked these similar questions
a) What role does 'alternation of generation' play in encouraging
survival of simple plants like the Bryophytes and Hepatophytes.
b) i) Anthrophytes also show alternation of generation. Identify
the structures that represent these two stages in its life cycle.
ii) Explain why the alternation of generation in Anthrophytes must
be different from that of the Bryophytes.(-
a. Describe the function of plant roots.
b) Describe the function of plant shoots.
c)What is the function of lignin in terrestrial plants?
d)What are xylem and phloem and how do they differ?
e)Exactly what is pollen?
f)Exacly what is a seed?
Which of the following comparisons between the moss life cycle and fern life cycle are correct? A) Mosses have flagellated sperm that need water to reach the female gamete, while the sperm of ferns are unflagellated and are not dependent on water.B) The sporophyte generation is smaller than the gametophyte generation in mosses, but the sporophyte generation is much larger than the gametophyte generation in ferns.C) The spores are produced in capsules on stalks in mosses but in small structures called sori on the underside of leaves in ferns.D) The gametes are produced in gametangia in mosses but in specialized structures on the underside of leaves in ferns.E) Both kinds of plants depend on wind for dispersal of spores.
