Question:
Most moss gametophytes do not have a cuticle and are 1-2 cells thick. What does this imply about moss gametophytes and their structure?
A) They use stomata for gas exchange regulation.
B) They can easily lose water to, and absorb water from, the atmosphere.
C) Photosynthesis occurs throughout the entire gametophyte surface.
D) They have branching veins in their leaves.
Answer:
B) They can easily lose water to, and absorb water from the atmosphere.
Step-by-step explanation:
The stages that produce sex cells in plant and undergo alternation of generation is known as the gametophyte. The sex cells are not produced through meiosis. They use meiosis to produce spores instead of sex cells, then it undergoes mitosis and grow to new haploid organisms. The moss gametophyte is a stage that lives more, it often grows from the gametophyte carpet.
Cuticle is the outer most layer of the plant that interacts with the environment.
Since most moss gametophyte do not have a cuticle and are 1-2 cell thick, they now absorb and lose water through their leaves from the atmosphere
