Based on the text, what environmental conditions are crucial for successful sexual reproduction in many bryophyte species?

  • A: Dry habitats to promote spore dispersal by wind.
  • B: Abundant direct sunlight for optimal photosynthesis.
  • C: A consistent film of water for sperm motility and close proximity of male and female gametophytes.
  • D: Cool temperatures to inhibit desiccation.

Explanation

The text states that 'Flagellated sperm swim through a film of water toward eggs' and that 'sexual reproduction is likely to be more successful when individuals are located close to one another.' These two conditions, abundant water and proximity, are crucial for their sexual reproduction.
