Nonvascular and Seedless Vascular Plants Lab

Question 1

When does meiosis occur in the plant life cycle?

Answer 1

Production of spores.

Question 2

When does meiosis occur in the animal life cycle?

Answer 2

Production of Gametes

Question 3

Which generation produces gametes in plants?

Answer 3

Gametophyte

Question 4

Gametophyte (Nonvascular Plants)

Answer 4

Dominant & Conspicuous

Question 5

Sporophyte (Nonvascular Plants)

Answer 5

Dependent upon gametophyte

Question 6

Phrases that describe nonvascular plants.

Answer 6

• No vascular tissue to transport water
• Flagellated sperm that swim to egg
• Dominant gametophyte

Question 7

What features are because nonvascular plantsare low-lying?

Answer 7

• No vascular tissue
• Flagellated sperm

Question 8

In nonvascular plants, windblown spores are dispersal agents, and some species forcefully expel their spores. How are windblown spores an adaptation to reproduction on land?

Answer 8

Don’t have to have water for dispersal.

Question 9

The leafy green shoots of a moss.

Answer 9

Are said to lack true roots, stems, & leaves because, by definition, roots, stems, & leaves are structure that contain vascular tissue.

Question 10

By what process are the spores being produced?

Answer 10

Meiosis

Question 11

When spores germinate, what generation begns to develop?

Answer 11

Gametophyte

Question 12

Why is it proper to say that spores are dispersal agents?

Answer 12

Wind can carry them.

Question 13

Phrases that describe seedless vascular plants.

Answer 13

• Independent gametophyte
• Flagellated sperm

Question 14

Are seedless vascular plants fully adapted to living on land?

Answer 14

No

Question 15

Gametophyte (Vascular Seedless Plants)

Answer 15

• Independent
• Photosynthetic
• Reduced

Question 16

Sporophyte (Vascular Seedless Plants)

Answer 16

Dominant

Question 17

Why in particular does sexual reproduction require moisture?

Answer 17

Because of the flagellated sperm requiring water to get to the egg.
