thin, rootlike structures that anchor them
green, fuzzy parts with leaflike structures

Which group of nonvascular plants typically grows as a thick crust on moist rocks or along the sides of streams?

How do the sperm cells of nonvascular plants reach the egg cells during reproduction?
The sperm cells are blown by the wind and land on the egg cells.
The sperm cells are forcefully ejected from their capsules to hit the egg cells.
The sperm cells swim to the egg cells through their watery surrou
The sperm cells swim to the egg cells through their watery surroundings. Nonvascular plants, such as mosses, liverworts, and hornworts, require water for reproduction because their sperm cells have flagella and must swim through a thin layer of water to reach the egg cells for fertilization to occur. This reliance on water for reproduction is one reason why these plants are commonly found in moist environments.
A moss reproduces through spores contained _____.
in fuzzy green, leaflike gametophytes
in rootlike structures called rhizoids
in a capsule at the end of a stalk
in layers of blackish-brown peat
