-

-
Kelelawar
-
Angin
Correct Answer
A. AnginExplanation
Gymnosperms are a group of plants that do not produce flowers or fruits. Instead, they rely on the wind for pollination. The male reproductive structures of gymnosperms, called cones, release pollen grains into the air. These pollen grains are carried by the wind and may land on the female reproductive structures of other gymnosperms, leading to fertilization. This method of pollination is known as anemophily, and it is the primary way that gymnosperms reproduce. Therefore, the correct answer is "Angin" (wind).Rate this question:

-
Protonema
-

-
Anteridium
-
Spora
-
Arkegonium
Correct Answer
A. SporaExplanation
The correct answer for this question is "Spora". The sporophyte generation in moss plants is responsible for producing spores. Spores are reproductive structures that can develop into new gametophyte plants. This is a crucial part of the moss life cycle, as the spores are dispersed and can eventually give rise to new moss plants. Therefore, the sporophyte generation in mosses is primarily involved in the production of spores.Rate this question:

-
Andrea petrophila
Correct Answer
A. Marchanti polymorphaExplanation
Marchanti polymorpha is a type of liverwort that is commonly used by rural communities to treat hepatitis or liver inflammation. Liverworts have been traditionally used in herbal medicine for their potential medicinal properties. Marchanti polymorpha may contain compounds that have hepatoprotective effects, meaning they can protect and support the health of the liver. Therefore, it is likely that the rural community utilizes Marchanti polymorpha as a natural remedy for treating hepatitis or liver inflammation.Rate this question:

-
Makrospora
Correct Answer
A. PeralihanExplanation
Based on the spores produced by Equisetum debile in the picture, it can be concluded that it belongs to the type of fern plants that undergo alternation of generations. This is because the spores are produced as part of the reproductive cycle in ferns, where they undergo alternation between a gametophyte and a sporophyte stage. Therefore, the correct answer is "Peralihan" which means alternation in Indonesian.Rate this question:

Sporogonium
-
Sporofit dan gametofit
-
Sporofit
-
Gametofit
Correct Answer
A. SporofitExplanation
The correct answer is "Sporofit". Metagenesis in the life cycle of ferns is dominated by the sporophyte generation. This means that the fern undergoes alternation of generations, where the dominant phase is the sporophyte, which is the multicellular diploid phase that produces spores through meiosis. The spores then develop into the gametophyte generation, which is a multicellular haploid phase that produces gametes. However, in the case of ferns, the sporophyte generation is the larger, more dominant phase in the life cycle.Rate this question:

Correct Answer
A. P dan RExplanation
The correct answer is P and R. This is because the question is asking about the sequential occurrence of the sporophyte and gametophyte phases in the life cycle of moss. In mosses, the sporophyte phase produces spores, and the gametophyte phase produces gametes. The diagram P shows the sporophyte phase, while diagram R shows the gametophyte phase. Therefore, the correct answer is P and R, indicating that the sporophyte phase occurs before the gametophyte phase in the life cycle of moss.Rate this question:

-
Araucaria cuninghamii, Pinus mercusii, Gnetum gnemon
Correct Answer
A. Araucaria cuninghamii, Pinus mercusii, Gnetum gnemonExplanation
Plants that reproduce with male and female strobili are Araucaria cuninghamii, Pinus mercusii, and Gnetum gnemon. Strobili are reproductive structures in plants that produce spores or gametes. These three plant species have separate male and female strobili, allowing them to reproduce sexually. This means that they require both male and female structures to produce offspring. Cycas rumphii, Musa paradisiaca, Pinus mercusii, Gnetum gnemon, Araucaria cuninghamii, solanum tuberosum, Magnolia grandifolia, Agathis alba, and Ficus benjamina do not have this specific reproductive mechanism, making them incorrect answers.Rate this question:

The correct answer is 2 and 7. The endosperm is formed through the fusion of nuclei in the embryo sac. In Angiosperms, the embryo sac contains two polar nuclei in the center, and these nuclei fuse with one sperm nucleus each to form the endosperm. Therefore, the fusion of nuclei with numbers 2 and 7 is responsible for the formation of the endosperm in Angiosperms.Rate this question:

-
Protonema → anteridium → spermatizoid
-
Tumbuhan lumut → arkegonium → sel telur
-
Spermatozoid atau sel telur → zigot → sporofit
Correct Answer
A. Sporofit → spora → protonemaExplanation
The correct answer is Sporofit → spora → protonema. In the life cycle of moss, the sporophyte is the diploid (2n) phase that produces haploid (n) spores through meiosis. These spores then germinate and develop into the protonema, which is a filamentous structure that serves as the vegetative stage of the moss. The protonema eventually gives rise to the mature moss plant. Therefore, the sequence of Sporofit → spora → protonema represents the vegetative phase of the moss life cycle.Rate this question:

A. 1,4,3,6,5,2Explanation
The correct answer is 1,4,3,6,5,2. This is the correct sequence of the life cycle of moss. It starts with the spore, which germinates into a protonema. The protonema then develops into a mature moss plant. The mature plant produces anteridia and archegonia, which are the male and female reproductive structures. Fertilization occurs, resulting in the formation of a sporophyte called sporogonium. The sporogonium produces spores, which are released and can germinate to start the cycle again.Rate this question:

The correct answer is 3-5-4-2-1. This is because the correct sequence of events in the reproduction of angiosperms is as follows: first, the pollen grains (serbuk sari) stick to the stigma (kepala putik) of the flower (event 3). Then, the pollen tube grows and reaches the ovule, where fertilization occurs (event 5). After fertilization, the zygote develops into an embryo (event 4).
