Soal IPA Kelas 6 Sd Bab Perkembangbiakan Makhluk Hidup

The correct answer is "Beranak". This answer is correct because humans reproduce through viviparous or live birth.

Lebah adalah hewan yang dapat membantu penyerbukan pada tumbuhan. Lebah memiliki bulu-bulu halus yang mampu menangkap serbuk sari dari bunga dan membawanya ke bunga lain untuk penyerbukan silang. Selain itu, lebah juga sering mengunjungi banyak bunga dalam satu waktu, sehingga memungkinkan penyerbukan yang efektif. Gajah, ayam, dan jangkrik tidak memiliki peran yang signifikan dalam penyerbukan tumbuhan.

Based on the given information, Joko experienced puberty at the age of 13, Ani at the age of 12, and Reza at the age of 15. This indicates that the beginning of puberty is not the same for everyone.

The correct answer is "Ovovivipar." Ovovivipar refers to the reproductive process in which eggs are retained inside the mother's body until they are ready to hatch. The embryos receive nourishment from the yolk of the eggs and are born live. This method of reproduction is seen in certain species of fish, reptiles, and invertebrates.

The correct answer is Angsa, itik, dan bebek. These animals reproduce by laying eggs.

Pubertas adalah masa perubahan fisik yang dialami oleh anak saat mereka memasuki masa remaja. Pada masa ini, terjadi perkembangan seksual sekunder seperti pertumbuhan payudara pada perempuan dan pertumbuhan rambut pada area ketiak dan kemaluan pada laki-laki. Selain itu, terjadi juga perubahan hormonal yang mempengaruhi perkembangan fisik dan emosional anak. Masa pubertas biasanya dimulai sekitar usia 10-14 tahun pada perempuan dan 12-16 tahun pada laki-laki.

The correct answer is "Alami dan buatan". This is because the question is asking about the two types of vegetative development, and the options provided are "Alami" (natural) and "Buatan" (artificial). Therefore, the correct answer is the option that includes both "Alami" and "Buatan".

The correct answer is "Sperma" because sperm is the male reproductive cell or gamete that is produced in the male reproductive organs. It is responsible for fertilizing the female egg or ovum during sexual reproduction.

The correct answer is Ayam, bebek dan angsa. These animals reproduce by laying eggs, which is a characteristic of oviparous animals.

The correct answer is "Bawang merah, bawang putih, dan bawang bombay." These plants reproduce by using underground bulbs called "umbi lapis." These bulbs store nutrients and act as a means of asexual reproduction for the plants. When the bulbs are planted, they can grow into new plants, resulting in the propagation of the species. Bawang merah, bawang putih, and bawang bombay are all examples of plants that reproduce in this manner.

During mating season, both chickens and cats exhibit a behavior known as "berkejar-kejaran" or chasing each other. This behavior is a way for the male to show his interest in the female and to initiate the mating process. The male will chase the female in an attempt to catch her, while the female may also run away to test the male's persistence. This behavior is a common observation in both chickens and cats during their mating rituals.

The correct answer is "Benang sari." In a flower, the male reproductive organ is called the stamen, which consists of the filament and the anther. The filament is a long, slender stalk, and the anther is the top part that produces pollen. The pollen contains the male gametes, which are necessary for fertilization. Therefore, the "benang sari" or "stamen" is the correct answer as it represents the male reproductive organ in a flower.

Pertumbuhan adalah proses yang disertai dengan pertambahan berat, besar, dan tinggi pada makhluk hidup. Selama pertumbuhan, makhluk hidup mengalami perubahan fisik dan perkembangan organisme yang lebih matang. Pertumbuhan melibatkan peningkatan jumlah sel dan ukuran organisme secara keseluruhan.

The correct answer is "Generatif". This is because the statement mentions that pigeons reproduce by laying eggs, which is a characteristic of sexual reproduction or generative reproduction. Vegetative reproduction involves the production of new individuals through the growth and development of vegetative structures such as roots, stems, and leaves. Membelah diri refers to the process of an organism splitting into two or more parts, each of which can grow into a new individual. Spora refers to the production of spores, which are reproductive cells that can develop into new individuals.

The correct answer is Pisang dan bambu. Both banana and bamboo can reproduce through vegetative propagation, specifically through the formation of shoots or suckers. This means that new plants can grow from existing parts of the parent plant, such as rhizomes or underground stems. This method of reproduction is common in certain plant species, including banana and bamboo, and allows for the rapid spread and expansion of these plants.

Ovarium pada tubuh wanita melepaskan sel telur dengan jangka waktu sebulan sekali. This means that the ovaries in a woman's body release an egg once a month.

Generative reproduction in plants can only occur in plants that have flowers. Flowers are the reproductive organs of plants that contain both male and female reproductive structures, such as stamens and pistils. These structures are responsible for the production of pollen and ovules, which are necessary for sexual reproduction. Therefore, plants without flowers, such as ferns or mosses, cannot undergo generative reproduction.

The correct answer is "Spora". Jamur, tumbuhan paku, dan lumut adalah contoh tumbuhan yang tidak berbiji. Tumbuhan-tumbuhan ini berkembang biak dengan cara memproduksi dan melepaskan spora. Spora adalah sel reproduksi yang dapat tumbuh menjadi individu baru.

The given options describe physical developments in boys. The first option states that the voice becomes louder, which is a physical change that occurs during puberty. The second option mentions that the voice becomes clearer or more resonant, which is also a physical change that happens during puberty. The third option states that the shoulders become broader, resulting in a wider chest, which is another physical change that occurs during adolescence. The last option mentions the growth of a beard or facial hair, which is a physical change specific to males during puberty. However, the correct answer is "Sura menjadi lebih nyaring," which means "The voice becomes louder." This option does not accurately describe a physical change that occurs during puberty.

Tumbuhan cocor bebek berkembang biak dengan tunas daun. This means that the plant reproduces by using leaf buds.

The correct answer is "Tunas, tunas daun, umbi lapis, umbi batang, umbi akar, akar tinggal dan geragih." This is because the options provided describe different methods of vegetative propagation in plants. In this answer, all the mentioned methods are included, such as the formation of new shoots, leaf buds, stem tubers, root tubers, underground bulbs, as well as the ability of roots to stay in the ground and form adventitious buds.

Merunduk is the correct answer because it refers to the process of plants reproducing by burying the growing branches into the soil. This method allows the buried branches to develop roots and grow into new plants. Stek refers to the process of taking a cutting from a parent plant and growing it into a new plant. Okulasi and Mengenten are methods of grafting, which involve joining the tissues of two different plants to create a new plant.

Penyerbukan yang terjadi jika serbuk sari yang jatuh di atas kepala putik berasal dari tanaman yang berbeda tetapi masih satu jenis disebut penyerbukan silang.
