Plant Growth and Reproduction

There are a few different ways that scientists have classified plants. Which of the following is not a way we have discussed?

• Small vs. Large

• Seed vs. Seedless

• Vascular vs. Nonvascular

• Angiosperms vs. Gymnosperms

An angiosperm is a plant that

• produces seeds inside of cones.

• produces flowers and fruit.

• is wind pollinated.

• produces spores rather than seeds.

Gymnosperms are plants that

• produce seeds inside of cones.

• produce flowers and fruit.

• are pollinated by animals.

• produce spores rather than seeds.

Vascular plants typically grow larger than nonvascular plants because

• they are able to absorb water and nutrients directly into all of their tissues from the environment.

• they are able to photosynthesize.

• they are able to deliver water and nutrients more efficiently to all of their tissues.

• they produce spores that can liver in very harsh conditions.

Nonvascular plants need to remain quite small for a number of reasons. Which of the following is not one of them?

• In order for fertilization to take place, sperm must actually swim through water to a female plant.

• They produce seeds that would be too heavy for the plant to support if it were larger.

• They don't have true roots, stems, or leaves, so many life process would not occur efficiently enough to support a larger plant.

• They must absorb water and nutrients directly into all of their tissues from the environment.
