plant classification

Which group of vascular plants do NOT make seeds?

• Coniferous trees

• Ferns

• Pines

• Flowering Plants

Answer explanation

Ferns are a group of vascular plants that reproduce via spores and do not produce seeds, unlike coniferous trees, pines, and flowering plants, which all do make seeds.

Which plant parts do scientists use to classify plants?

• Mainly roots and leaves

• Mainly flowers and seeds

• Mainly leaves and stems

• All plant parts

Answer explanation

Scientists classify plants using all plant parts, including roots, leaves, stems, flowers, and seeds. Each part provides important information about the plant's characteristics and relationships to other species.

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.

Why is the plant in the picture a vascular plant?

• it can absorb light from the sun

• it has a stem that can carry water and nutrients

• it has more than one cell

• it can make it's own food

Answer explanation

The plant is a vascular plant because it has a stem that can carry water and nutrients, which is a key characteristic of vascular plants. This allows them to transport essential resources throughout the plant.

Nonvascular plants

• reproduce by making seeds

• grow close to the ground

• are tall and thin

• live in dry places and have long roots

Answer explanation

Nonvascular plants, such as mosses, lack the structures to grow tall and typically thrive in moist environments. They grow close to the ground to absorb water and nutrients directly, making 'grow close to the ground' the correct choice.

Which of these is NOT a way to classify plants?

• as vascular and nonvascular

• as vertebrates and invertebrates

• as seed producing and spore producing

Answer explanation

The classification of plants does not include 'vertebrates and invertebrates', as this categorization applies to animals, not plants. The other options are valid ways to classify plants.

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.

Which of these is NOT a trait or example of a gymnosperm?

• has seeds

• vascular

• apple tree

• pine tree

Answer explanation

An apple tree is a type of angiosperm, which produces flowers and fruits, while gymnosperms, like pine trees, have exposed seeds and do not produce flowers. Therefore, 'apple tree' is not a trait or example of a gymnosperm.
