Nonvascular Plants and Seedless Vascular Plants

What group of green algae is most closely related to land plants?

• Chlorophytes

• Charophytes

• Rhodophytes

• Phaeophytes

In the plant life cycle, what is meant by the 'dominant generation'?

• The dominant generation is the phase of the plant life cycle that is most conspicuous and long-lived, typically either the sporophyte or gametophyte depending on the plant group.

• The dominant generation is the phase where the plant produces flowers and fruits only.

• The dominant generation refers to the shortest phase in the plant life cycle.

• The dominant generation is the phase when the plant is dormant and not growing.

How does the role of meiosis differ between plant and animal life cycles?

• In plants, meiosis produces spores that develop into gametophytes, while in animals, meiosis produces gametes directly.

• In plants, meiosis produces gametes directly, while in animals, meiosis produces spores.

• In both plants and animals, meiosis produces gametes that develop into sporophytes.

• In animals, meiosis produces spores that develop into gametophytes, while in plants, meiosis produces gametes directly.

What adaptation helps nonvascular plants reproduce on land?

• Nonvascular plants have adaptations such as retention of the zygote and protection of reproductive cells from drying out.

• Nonvascular plants have deep root systems to absorb water from the soil.

• Nonvascular plants produce seeds that can be dispersed by wind.

• Nonvascular plants have thick, waxy leaves to prevent water loss.

In the moss life cycle, what are the two generations called?

• Gametophyte and sporophyte

• Zygote and embryo

• Protonema and capsule

Which of the following is a group of nonvascular plants?

• Ferns

• B) Horsetail

• C) Liverwort

• D) Lycophyte

In the fern life cycle, what is the dominant generation?

• Sporophyte

• Gametophyte

• Prothallus

What is the function of a waxy cuticle in land plants?

• It prevents water loss from the plant's body.

• It helps in photosynthesis directly.

• It absorbs nutrients from the soil.

• It attracts pollinators.
