Plant Life Cycles and Adaptations

Chapter 29 introduces plant evolution from water to land, classifying plants into nonvascular and vascular categories. It discusses plant adaptations like cuticles and stomata for terrestrial life. The video details nonvascular plants, such as bryophytes, and seedless vascular plants, like ferns, explaining their life cycles and reproductive strategies.

What is a key characteristic of nonvascular plants?

• They are typically large in size.

• They possess vascular tissue.

• They have a complex root system.

• They lack vascular tissue.

Which group of plants is known for producing cones?

• Gymnosperms

• Angiosperms

• Nonvascular plants

• Seedless vascular plants

What adaptation helps plants prevent water loss?

• Stomata

• Cuticle

• Roots

• Flowers

What is the function of stomata in plants?

• To absorb nutrients from the soil

• To exchange gases with the environment

• To store water

• To conduct photosynthesis

In the life cycle of mosses, what is the role of the gametophyte?

• It produces spores.

• It is the dominant photosynthetic stage.

• It is nutritionally dependent on the sporophyte.

• It forms the seed.

What is a bryophyte?

• A nonvascular plant like mosses

• A type of seedless vascular plant

• A plant with cones

• A flowering plant

Which stage is dominant in the life cycle of ferns?

• Sporophyte

• Seed

• Gametophyte

• Spore

What is the function of sori in ferns?

• To release spores

• To conduct photosynthesis

• To absorb water

• To produce seeds

How do seedless vascular plants like ferns reproduce?

• By cloning

• By budding

• By producing seeds

• By producing spores

What is the underground stem of a fern called?

• Sori

• Rhizome

• Root
