Lumut (Bryophyta) merupakan tumbuhan peralihan antara tumbuhan talus dan tumbuhan kormus yang mempunyai ciri, yaitu . . .
Correct Answer
C. Mempunyai rhizoid
Explanation
Lumut (Bryophyta) is a transitional plant between thallus plants and stem plants that has the characteristic of having rhizoids. Rhizoids are root-like structures that anchor the plant to the substrate and absorb water and nutrients. Unlike true roots, rhizoids do not have specialized tissues for conducting water and nutrients, which is why lumut does not have vascular tissue or a true stem. The presence of rhizoids is a defining characteristic of bryophytes like lumut.
23.
Tumbuhan lumut mempunyai ciri-ciri seperti tersebut di bawah ini, . . .
Correct Answer
C. Heterotrof
Explanation
The given characteristics of the plant, such as living in a moist environment, having roots, and transporting water and minerals through xylem, are all true for mosses. However, the characteristic of being heterotrophic is not accurate for mosses. Mosses are actually autotrophic, meaning they can produce their own food through photosynthesis. Therefore, the correct answer is not heterotrophic.
24.

This means that the cells in the sporophyte generation have two sets of chromosomes, one from each parent. This is in contrast to the gametophyte generation, which has a haploid number of chromosomes.
26.
Pernyataan yang TIDAK benar mengenai tumbuhan lumut di bawah ini adalah . . .
Correct Answer
E. Sporanya berkembang menjadi prothalium
Explanation
The incorrect statement about moss plants is that their spores develop into prothallium. Moss plants do not have prothallium, as prothallium is a structure found in ferns and some other types of plants. Moss plants have a different reproductive structure called a gametophyte.
27.

Therefore, Selaginella is the correct answer for this question.
31.
Menurut fungsinya daun pteridophyta untuk fotosintesis yaitu . . .
Correct Answer
B. Tropofil
Explanation
The correct answer is "Tropofil". Tropofil refers to the leaves of pteridophytes that are adapted for photosynthesis. These leaves have specialized structures and adaptations that allow them to efficiently capture sunlight and carry out the process of photosynthesis. They have a large surface area and are typically thin and broad, which helps in maximizing the absorption of light. Tropofil leaves also have stomata, which are small openings that regulate the exchange of gases, such as carbon dioxide and oxygen, during photosynthesis. Overall, the tropofil leaves of pteridophytes play a crucial role in the process of photosynthesis.
32.
Ciri utama yang menyebabkan pteridophyta tidak digolongkan ke dalam kelompok antophyta adalah . . .
Correct Answer
D. Tidak ditemukan bunga
Explanation
The main characteristic that distinguishes pteridophyta from angiosperms is the absence of flowers. Pteridophytes reproduce through spores instead of seeds, and they do not produce flowers or fruits like angiosperms do. This is why they are not classified as part of the angiosperm group.
33.
Persamaan tumbuhan lumut dan tumbuhan paku kecuali . . .
Correct Answer
D. Mempunyai akar serabut
Explanation
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.
34.
Tumbuhan yang merupakan peralihan antara talophita ke kormophita adalah . . . .
Correct Answer
E. BryopHita
Explanation
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.
35.
Alat pada lumut yang berfungsi untuk menempel dan menyerap air dan garam mineral adalah . .
Correct Answer
B. Rhizoid
Explanation
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.
36.
Generasi sporofit pada tumbuhan lumut adalah generasi yang menghasilkan . . . .
Correct Answer
D. Spora
Explanation
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.
37.
Pada daur hidup lumut, protonema berkembang membentuk . . . .
Correct Answer
D. Tumbuhan lumut dewasa
Explanation
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. Therefore, the tumbuhan lumut dewasa (mature moss plant) is the correct answer.
38.
Tumbuhan lumut mempunyai ciri-ciri seperti tersebut di bawah ini kecuali . . . .
Correct Answer
D. Berumah satu atau berumah dua
Explanation
The given options describe characteristics of moss plants. Moss plants are known to live in damp environments, have an annulus to control the release of spores, and have chlorophyll for photosynthesis. They also have a structure called sporogonium that produces spores. However, moss plants do not have the characteristic of being monoecious or dioecious, which means they do not have separate male and female reproductive structures.

44.
Pada tumbuhan paku, bagian yang memiliki jumlah kromosom 2n (diploid) adalah . . . .
Correct Answer
A. Tumbuhan paku sendiri
Explanation
The correct answer is "tumbuhan paku sendiri" because in fern plants, the sporophyte stage is the diploid stage with 2n chromosomes. The sporophyte is the mature fern plant itself, which produces spores through meiosis. The spores are haploid and develop into the gametophyte stage, which is the haploid stage of the plant's life cycle. Therefore, the diploid stage in fern plants is the mature fern plant itself.
