Plants and Flowers Quiz

Roots are the primary plant organs responsible for absorbing water and dissolved minerals from the soil. They also anchor the plant in the ground.

The stamen is the male reproductive part of a flower, consisting of an anther and a filament. The carpel (or pistil) is the female reproductive part.

Deciduous plants are those that shed their leaves annually, typically in the autumn. This is a survival strategy to conserve water and energy during colder or drier seasons.

An oak tree is an angiosperm, which means it is a flowering plant that produces seeds enclosed within a fruit or nut. Mosses, seaweed, and fir trees are nonflowering plants.

Dendrochronology is the study of tree rings. Each ring typically represents one year of growth, allowing one to estimate the age of most trees.

Water lilies are aquatic plants that have evolved to disperse their seeds via water currents. The other plants listed use wind or animals for seed dispersal.

Ferns are vascular plants that reproduce via spores rather than seeds or flowers. Oak trees and dandelions are flowering plants.

An annual plant completes its entire life cycle, from germination to seed production and death, within a single growing season or year.

Leaves are the primary site of photosynthesis, a process where plants use sunlight, water, and carbon dioxide to create glucose for energy.
