Question

what is an angiosperm?
a division of plants that bear their seeds within a layer of tissue that protects it
a division of plants that reproduces using rhizomes that grow underground
a division of plants that reproduces using spores that are cast off in the spring
a division of plants that leave their seeds exposed on the scales of cones

Explanation:

To determine the correct answer, we recall the definition of angiosperms. Angiosperms are flowering plants that have seeds enclosed within a protective tissue (the ovary, which develops into fruit). Let's analyze each option:

• The first option: "a division of plants that bear their seeds within a layer of tissue that protects it" matches the definition of angiosperms (seeds are enclosed in protective tissue like an ovary/fruit).
• The second option: Plants that reproduce using rhizomes (underground stems) are typically like some ferns or grasses, not angiosperms' main reproductive feature.
• The third option: Plants that reproduce via spores are non - seed plants (like ferns, mosses), while angiosperms reproduce via seeds.
• The fourth option: Plants with seeds exposed on cone scales are gymnosperms (e.g., pine trees), not angiosperms.

Answer:

A. a division of plants that bear their seeds within a layer of tissue that protects it
