- E.
Tergolong dalam kormophyta berspora
Correct Answer
D. Mempunyai akar serabutExplanation
The correct answer is "Mempunyai akar serabut". This is because both mosses and ferns have rhizoids instead of true roots. Rhizoids are thread-like structures that help anchor the plants to the ground and absorb water and nutrients, but they do not perform the same functions as true roots. Therefore, the statement "Mempunyai akar serabut" is not true for both mosses and ferns.Rate this question:

- E.
Bryophita
Correct Answer
E. BryophitaExplanation
Bryophytes are plants that represent the transition between thallophytes (algae, lichens, and fungi) and cormophytes (vascular plants). They are non-vascular plants that lack true roots, stems, and leaves but have specialized structures for water absorption and reproduction. Bryophytes include mosses, liverworts, and hornworts. They have simple structures and rely on water for reproduction, similar to thallophytes. However, they have some characteristics of cormophytes, such as having specialized tissues for conducting water and nutrients. Therefore, bryophytes are considered a transitional group between thallophytes and cormophytes.Rate this question:

Correct Answer
B. RhizoidExplanation
A rhizoid is a structure found in mosses and some other non-vascular plants that functions to anchor the plant to a substrate and absorb water and minerals. Unlike true roots, rhizoids do not have specialized tissues or structures for conducting water and nutrients. Instead, they rely on direct absorption from the surrounding environment. This adaptation allows mosses to thrive in moist environments where they can absorb water and nutrients directly from the substrate they are attached to. Therefore, the correct answer for the given question is rhizoid.Rate this question:

Protonema
- B.
Gamet
- C.
Anteridium
- D.
Spora
- E.
Arkegonium
Correct Answer
D. SporaExplanation
The correct answer is "spora". In moss plants, the sporophyte generation produces spores. Spores are reproductive cells that can develop into new individuals. This is a crucial part of the moss life cycle, as the spores are dispersed and can germinate into new gametophytes, which then produce gametes for sexual reproduction. Therefore, the sporophyte generation in mosses is responsible for producing spores.Rate this question:

- E.
Anteridium dan arkegonium
Correct Answer
D. Tumbuhan lumut dewasaExplanation
The correct answer is "tumbuhan lumut dewasa". In the life cycle of mosses, the protonema develops into the mature moss plant. The protonema is the first stage of growth in mosses, which is a thread-like structure that forms from the germinating spore. As the protonema grows, it eventually develops into the mature moss plant, which consists of the leafy gametophyte and reproductive structures called archegonia and antheridia.

Correct Answer
D. Berumah satu atau berumah duaExplanation
The correct answer is "berumah satu atau berumah dua" because moss plants do not have a well-developed reproductive system with distinct male and female structures. Instead, they have structures called gametophytes that produce both male and female reproductive cells. Therefore, they are not classified as having "one house" (monoecious) or "two houses" (dioecious) like other plants with separate male and female individuals.Rate this question:
