Which of these is not true about bryophytes?
a. Produce spores carried by insects.
Spores can be spread out by the air. All other options are completely true about bryophytes, so according to me answer is (a).
The non-vascular plants are the......
a. Hornwarts, liverworts and mosses.
Option (b) and (c) are not vascular as well. But the key here is that they've asked plants that are non-vascular, and fungi, slime, water mold, and algae are not plants. So, the answer is (a).Hornwarts, liverworts and mosses are bryophytes and they are non vascular.
Which of these best describe a protonema?
a. An algae like branching filament that is a result of spore germination.
All other options are inappropriate. Option (a) is correct. Becuase protonema is not a structure that produces sperms or eggs. The rest of the options are also irrelevant.
Which of these best describe the gametophyte in the alteration of generation life cycles?
a. Generation that produces the gametes. Gametophytes are haploid and they produce gametes. Option (b) is false, its true for sporophytes. Option (c) is again true for sporophytes. Option (d) is inappropriate and option (e) is again true for sporophytes.
Plants have a/an ........ life cycle.
a. an alternation of generation life cycle
