Biology U2 L3 - Nonvascular Plants

Front 1

Compare and contrast a leafy liverwort and a thallose liverwort.

Back 1

Thallose liverworts have a broad, ribbonlike body that resembles a fleshy, lobes leaf. Leafy liverworts have three rows of flat, thin leaflike structures attached to a stem.

Front 2

Explain how the bryophyte sporophyte generation is dependent on the bryophyte gametophyte generation

Back 2

The sporophyte generation is small and obtains food, water, and minerals from the larger gametophyte generation.

Front 3

Identify characteristics shared by all nonvascular plants.

Back 3

Nonvascular plants lack vascular tissues, are typically small in size, have a dominant gametophyte generation, and grow in moist, shady areas.

Front 4

Evaluate the significance of nonvascular plant adaptations to their moist environments.

Back 4

Since these plants rely on diffusion and osmosis for the transport of water and minerals, they tend to be found in areas where there is a lot of water.

Front 5

Identify the growth and development methods of mosses. Explain why these are advantageous in their environments

Back 5

The dense mats retain water and help reduce evaporation.

Front 6

Describe the variations in gametophyte and sporophyte generations of nonvascular plants.

Back 6

The gametophyte and sporophyte generations are both stages of the nonvascular plant life cycle. The sporophyte generation is smaller and dependent upon the gametophyte. The gametophyte generation is haploid and produces gametes, whereas the sporophyte generation is diploid and produces spores
