Classification of Plants

Which group do flowering plants belong to?

• ferns

• mosses

• seed plants

• coniferous plants

Answer explanation

Flowering plants are classified as seed plants because they reproduce through seeds, which are produced in flowers. This distinguishes them from ferns and mosses, which do not produce seeds.

How are apple trees and roses alike?

• they are both nonvascular

• they are both gymnosperms

• they are both angiosperms

• neither have seeds

Answer explanation

Apple trees and roses are both angiosperms, meaning they are flowering plants that produce seeds enclosed within a fruit. This distinguishes them from nonvascular plants and gymnosperms.

Which of these plants is nonvascular?

• apple tree

• fern

• dandelion

• moss

Answer explanation

Moss is a nonvascular plant, meaning it lacks specialized tissues for transporting water and nutrients. In contrast, apple trees, ferns, and dandelions are vascular plants with these systems.

A flower-producing vascular plant in which the seed is enclosed in a fruit.

• Angiosperm

• Gymnosperm

• Conifer

• Fern

Answer explanation

An angiosperm is a flower-producing vascular plant with seeds enclosed in a fruit, distinguishing it from gymnosperms, which have naked seeds, and ferns, which do not produce seeds at all.

What are the 2 MAIN groups of plants?

• seed plants and seedless plants

• gymnosperms and angiosperms

• horsetails and ferns

• vascular and nonvascular

Answer explanation

The two main groups of plants are vascular and nonvascular. Vascular plants have specialized tissues for transporting water and nutrients, while nonvascular plants lack these tissues, affecting their growth and habitat.

Which group of plants absorb water like a sponge?

• vascular 

• nonvascular

Answer explanation

Nonvascular plants, like mosses, absorb water directly through their tissues, functioning like a sponge. In contrast, vascular plants have specialized structures for water transport and do not absorb water in this manner.

Gymnosperms produce seeds usually in

• cones

• flowers

• fruit

• spores

Answer explanation

Gymnosperms produce seeds in cones, which are the reproductive structures that contain the seeds. Unlike flowering plants, they do not produce flowers or fruits.

Nonvascular plants usually grow in:

• damp, shady areas

• deserts

• arctic regions

• sunny fields

Answer explanation

Nonvascular plants, like mosses, thrive in damp, shady areas where moisture is abundant. They lack the vascular system to transport water efficiently, making these environments ideal for their growth.

The plant kingdom is divided into two main groups:

• flowering & non-flowering

• seed & seedless

• trees & plants

• conifers & flowering plants

Mosses, liverworts, and hornworts are ___ plants.

• nonvascular

• vascular
