Question

The unique feature of bryophytes is that they

• A. they produce spores
• B. have sporophyte attached to the photosynthetic gametophyte
• C. lack vascular tissues
• D. lack roots

Answer 1

The correct option is B have sporophyte attached to the photosynthetic gametophyte

The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte. The mature gametophyte produces both male and female gametes, which join to form a diploid zygote. The zygote develops into the diploid sporophyte, which extends from the photosynthetic gametophyte itself and remains attached to it. This is a feature unique to bryophytes.

Algae and bryophytes both lack roots and vascular tissues. Bryophytes produce spores to reproduce and so do algae. Algae reproduce asexually through the production of zoospores.
