Kingdom Plantae

Question 1

Kingdom Plantae

Answer 1

Are eukaryotic, multicellular organisms that are photoautotrophic, have cell walls, and exhibit alternation of generations.

Question 2

Alternation of generations

Answer 2

Alternation between the stages of a multicellular diploid sporophyte and a multicellular haploid gametophyte phase.

Question 3

Bryophyta

Answer 3

A group of non-vascular plants, including mosses, liverworts, and hornworts. They lack true roots, stems, and leaves. Require moist environments for reproduction and growth.

Question 4

Bryophyta dominate life-cycle

Answer 4

Has a gametophyte-dominant life cycle, with the gametophyte being the dominant phase.

Question 5

Phylum Bryophyta - Mosses

Answer 5

Most diverse group of bryophytes. They are small, herbaceous plants often found in damp habitats. Its gametophyte consists of leafy stems and rhizoids for anchorage. They reproduce via spores released from capsules borne on sporophytes.

Question 6

Phylum Hepatophyta - Liverworts

Answer 6

Liverworts have a flattened, ribbon-like thallus. Its gametophyte stage is dominant, while the sporophyte is short-lived. Some species have specialized structures called gemmae cups for asexual reproduction.

Question 7

Phylum Anthocerophyta - Hornworts

Answer 7

Hornworts have horn shaped sporophytes arising from a flattened gametophyte. Similar to liverworts, with a dominant gametophyte phase.

Question 8

Vascular plants without seeds are:

Answer 8

Tracheophytes

Question 9

Phylum Lycophyta - Club mosses

Answer 9

-Are tracheophytes
Have primitive vascular plants with small, scale-like leaves and reproduce by spores.

Question 10

Phylum pterophyta are:

Answer 10

Ferns and allies
Psilophyta (whisk ferns)
Sphenophyta (horsetails)
Pterophyta (true ferns)

Question 11

Phylum Pterophyta

Answer 11

A diverse group of vascular plants with true leaves (fronds) and roots. They reproduce via spores produced in sporangia on the underside of fronds.
