in which of the following plant groups is the gametophyte larger and longer lived than the sporophyte?
nonvascular plants
seedless vascular plants
angiosperms
gymnosperms

Explanation:

Identify the key question criteria

The question asks to identify the plant group where the gametophyte generation is larger and longer-lived (dominant) than the sporophyte generation.

Analyze the plant groups

• Nonvascular plants (bryophytes, such as mosses, liverworts, and hornworts) have a dominant gametophyte phase. The gametophyte is multicellular, photosynthetic, larger, and longer-lived, while the sporophyte is typically smaller, short-lived, and nutritionally dependent on the gametophyte.
• Seedless vascular plants (such as ferns) have a dominant sporophyte phase. The gametophyte is a tiny, independent, short-lived structure (prothallus).
• Gymnosperms and Angiosperms (seed plants) have a highly reduced, microscopic gametophyte that is completely dependent on the dominant, large, long-lived sporophyte.

Match with options

The correct group is "Nonvascular plants".

Answer:

• Nonvascular plants (Correct answer)
• Seedless vascular plants
• Angiosperms
• Gymnosperms
