Question 5 (5 points)

Solving the problem of the need for water in plant reproduction, which restricted plants to moist environments, was a major breakthrough in plant evolution. In what major group of plants did this first occur?

Question 5 options:

Save

Question 6 (5 points)

Plants need to take in carbon dioxide from the atmosphere and release oxygen, but the waxy cuticle overlaying the epidermis of stems and leaves to prevent water loss also prevents the exchange of gases. What structure found in many plants was the solution to this problem?

Question 6 options:

Save

Question 7 (5 points)

The fossil record is important to our understanding of plant evolution. The oldest plant fossil dates to 475 million years ago, and the fossil record for land plants spans almost 60 million years, documenting the origin of land plants. What fossilized remains were found early in the record that helped plants adapt to land by reducing water evaporation?

Question 7 options:

sheets of waxy material called cuticle

large leaves

vascular tissue

pollen

Save

	Deserts
	Tropical rainforests
	Savannahs
	Taiga (boreal forests)

Solution

Answer:

1). Taiga (boreal forests)

Taige forest vegetation: Needleleaf, coniferous (gymnosperm) trees are the dominant plants of the taiga biome. A very few species in four main genera are found: the evergreen spruce (Picea), fir (Abies), and pine (Pinus), and the deciduous larch or tamarack (Larix).

2). Diploid dominant

Typical animal have haploid stage at gametic conditions only, rest of the life cycle appears in diploid conditions.

3). alternation of generation

The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes. Gametophyte plants arehaploid, sporophyte plants diploid. This type of life cycle is called alternation of generations.

4). I do not know

5). club mosses (lycopods)

The common name “clubmoss” is based on the premise that at first glance these plants resemble mosses (mosses are bryophytes and thus, non-vascular plants), and because they often have club-like structures that produce spores. Clubmosses are all perennial evergreen plants with numerous small leaves.

6). Stomata

Stomata help in absorption of CO2 and also involves in evaporation of water.

7). sheets of waxy material called cuticle

Waxy layer will be found on the surface of the stomata that reduces evaporation of water
