SHORT ANSWER
A. In the sporophyte stage, plants make spores that grow into gametophytes. In the gametophyte stage, male gametophytes produce sperm and female gametophytes produce eggs.
B Nonvascular plants rely on diffusion, which is efficient only in small plants. Vascular plants have conducting tissues, which enable the plant to be very large.
C. A rhizoid is a rootlike structure that holds a nonvascular plant in place. A rhizome is a horizontal underground stem from which new roots and shoots can grow.
D. They are usually the first plants to live in a new area. When they die, they form a thin layer of soil in which other plants can grow. They also prevent soil erosion, are eaten by some animals, and are used for nesting material.
E.
1—Nonvascular plants which do not have a structure for moving water throughout the plant.
2—Seedless vascular plants which are plants that do have a structure for moving water throughout the plant, but have no seeds.
3—Gymnosperms which are plants that have a structure for moving water, have seeds, but do not flower.
4—Angiosperms which are plants that have a structure for moving water, have seeds, and have flowers.
F. Green algae & plants have much in common, such as the same kind of chlorophyll, similar cell walls, make food through photosynthesis, store energy in the form of starch, and have a 2-stage life cycle. These similarities make it appear likely that green algae and plants have a common ancestor, but algae are not a plant. Algae lacks roots, cuticles, and stems.
G. They help form soil, prevent erosion, help form communities, and add to soil depth.
H. The remains of seedless vascular plants that lived and died 300 million years ago formed coal. People mine coal from the Earth’s crust and use it for energy.
I. In the fern life cycle, the gametophyte is one structure that gives off both sperm and eggs. In the moss life cycle, there are both male and female gametophyte, with the male providing the sperm and the female providing the eggs.
J. Algae provide both food and oxygen to an ecosystem
M. Nonvascular plants do not have specialized tissue to transport water from one part of the plant to another, and rely on water in the environment or within other cells. In a dry environment, a nonvascular plant would die, or might evolve to rely on seasonal rains or on underground water.
