Pteridophytes differs from bryophytes in havingA vascular tissue B archaegonia C alternation of generation D motile sperm

The main difference between Pteridophytes and Bryophytes is that Pteridophytes have vascular tissues, while Bryophytes do not.

Step 1: Understand the terms

• Pteridophytes: These are a group of plants that have vascular tissues - xylem and phloem. They include ferns and their allies.
• Bryophytes: These are a group of plants that lack vascular tissues. They include mosses and liverworts.

Step 2: Compare the characteristics

• Vascular tissue: Pteridophytes have vascular tissues, which are specialized for the conduction of water and nutrients. Bryophytes lack these tissues.
• Archaegonia: Both Pteridophytes and Bryophytes have archaegonia, which are female reproductive organs in lower plants.
• Alternation of generation: Both Pteridophytes and Bryophytes exhibit alternation of generations, which is a life cycle that alternates between a sexual phase (the gametophyte) and an asexual phase (the sporophyte).
• Motile sperm: Both Pteridophytes and Bryophytes produce motile sperm for reproduction.

Step 3: Answer the question Therefore, the correct answer is A. Pteridophytes differ from Bryophytes in having vascular tissue.
