Question

Bryophytes differ from algae in having
A) Multicellular and jacketed sex organs
B) Embryogenesis in their life cycle
C) Gametophyte dependent on sporophyte
D) More than one option is correct

Answer 1

Both Bryophytes and Algae are a part of plant Kingdom under the five kingdom classification of organisms.
Algae are the primitive members of the plant Kingdom whereas bryophytes are a level higher to algae, this means they are more Complex plants when compared to algae.

Complete Answer:
To understand this question, let us evaluate the options step by step.

1. Option A is that bryophytes differ from algae in having multicellular and jacketed sex organs.
   So, we will compare the sex organs of both the members of plant Kingdom: The sex organs of Algae are normally one celled and without any sterile jacket where as the sex organs of bryophyta are multicellular and jacketed.
   Hence, the above option mentioning the difference of bryophytes from algae is correct.
2. Option B is embryogenesis in their life cycle. The difference of embryogenesis is not significant when we compare bryophytes from algae. So, this is not the correct option.
3. Option C is gametophyte of bryophyta is dependent on sporophyte. But when we see the characteristics of bryophytes we realize that the adult sporophyte of bryophyte is always dependent on the gametophyte. Gametophyte is the dominant phase of bryophyte. So, this is also not the correct option.

And hence, ultimately after the entire discussion the correct answer comes out to be option A.

Note: Bryophytes are the first land plants that occur in humid and Shady places but they require water for reproduction. And as bryophyta can live both on land and water they are known as the amphibians of the plant Kingdom.
This makes bryophytes different from the entire plant Kingdom.
