Uh Pertumbuhan Dan Perkembangan

The correct answer is A because the structure of the seed is a characteristic feature of dicotyledonous plants. Dicot seeds have two cotyledons, or seed leaves, which are present in the embryo of the seed. These cotyledons store nutrients for the developing plant and eventually become the first leaves of the seedling. In contrast, monocot seeds have only one cotyledon. Therefore, based on the given information, option A is the correct answer as it mentions the structure of the seed, which is a characteristic of dicot plants.

The correct order of the stages of human growth is as follows: bayi (infant), anak-anak (children), remaja (adolescent), dewasa (adult), manusia (human). Therefore, the correct answer is 3-5-2-1-4.

Pertumbuhan dalam biologi mengacu pada perubahan fisik berupa pertambahan ukuran, volume, tinggi, dan massa. Salah satu ciri dasar pertumbuhan adalah sel bertambah banyak dan besar. Sel-sel dalam organisme tumbuh dan berkembang menjadi lebih besar dan juga membelah untuk membentuk sel-sel baru. Dengan demikian, sel-sel bertambah jumlahnya dan juga ukurannya, sehingga menyebabkan pertumbuhan organisme secara keseluruhan.

Imbibisi is the correct answer because it refers to the process of water absorption by seeds. During germination, water from the external environment enters the seed coat through imbibition, which helps in the process of seed germination. This process is essential for the seed to absorb water and swell, allowing the embryo to grow and germinate.

The correct answer is Testa (Kulit biji). This is because in the given image, number 5 is labeled as Testa (Kulit biji). The testa is the outer protective layer of the seed that surrounds the embryo and endosperm. It provides protection to the inner parts of the seed and helps in preventing desiccation and mechanical damage.

When fruits need to ripen quickly, traders often use a gas called ethylene. Ethylene is a plant hormone that triggers the ripening process in fruits. It stimulates the production of enzymes that break down starches into sugars, softening the fruit and enhancing its flavor. This gas is commonly used by farmers and traders to control the ripening of fruits during transportation and storage.

Gibberelin is needed to eliminate the dwarf trait genetically in plants. Gibberelin is a plant hormone that promotes stem elongation and cell division. By applying gibberelin, the plants can overcome the genetic dwarfism and grow taller.

The correct answer is "merupakan proses yang bersifat reversibel." This is because plant growth is not a reversible process. Once a plant has grown, it cannot go back to its previous state. The other options, such as the addition of cell length, substances, or an increase in cell size and number, all contribute to the overall growth of a plant.

The correct order of germination processes is as follows: First, water enters the seed and causes the testa to break (imbibition). Then, the stored food in the cotyledon and endosperm is hydrolyzed by water and enzymes. After that, energy is produced through aerobic respiration using glucose and oxygen. Finally, the release of the hormone gibberellin by the embryo triggers the synthesis and activation of the enzymes alpha-amylase and protease by the aleuron.

The correct answer is "ujung akar" because the cells at the tip of the root have the ability to divide and undergo cell division. This allows the root to grow longer and explore the soil for nutrients and water. The other options, such as buah yang masak (ripe fruit), jaringan permanen (permanent tissue), bunga (flower), and batang (stem), do not typically have actively dividing cells like the root tip.

Pertumbuhan dan perkembangan adalah dua proses yang berbeda dalam kehidupan organisme. Pertumbuhan bersifat kuantitatif karena melibatkan penambahan ukuran dan massa sel. Sementara itu, perkembangan melibatkan perubahan kualitatif dalam struktur dan fungsi organisme. Dalam konteks ini, pertumbuhan tidak hanya melibatkan penambahan ukuran batang, tetapi juga melibatkan penambahan jumlah dan massa sel di seluruh organisme. Oleh karena itu, perbedaan antara pertumbuhan dan perkembangan adalah bahwa pertumbuhan bersifat kuantitatif dan melibatkan penambahan jumlah dan massa sel.

Cahaya dapat menghambat pertumbuhan karena cahaya dapat menguraikan kerja hormon auksin.

The correct answer is "Proses menuju tercapainya kedewasaan." This answer is supported by the definition of perkembangan, which refers to the process of reaching maturity or adulthood.

The correct answer is "Epikotil" because in the given image, the structure labeled as 7b is the part of the seedling that is located above the cotyledons and below the first true leaves. This structure is known as the epikotil.

The correct answer is Endosperm. The image shows a diagram of a seed, and the number 2 is pointing to the endosperm. The endosperm is a tissue that provides nutrients to the developing embryo in a seed. It is usually rich in starch and is responsible for the nourishment of the growing seedling until it can produce its own food through photosynthesis.

Gibberelin is a hormone that can be used to produce seedless watermelons. This hormone stimulates the growth and development of fruits, including watermelons, without the formation of seeds. By providing gibberelin, the watermelon plant can produce fruits that are seedless, which is desired by some consumers.

The correct answer is Embrio. The image shows the structure of a plant, and number 1 is pointing to the embryo. The embryo is the young, undeveloped plant within a seed that will eventually grow into a new plant.

Asam absisat berperan dalam menghambat pemanjangan sel pada pertumbuhan tanaman. Ini berarti bahwa asam absisat menghambat pertumbuhan tanaman dengan mencegah sel-sel tanaman untuk memanjang.

The correct answer is "penambahan besar dan jumlah sel dalam jaringan" because it states that growth will increase due to both an increase in size and number of cells in the tissue. This aligns with the concept of growth and development, as the growth of an organism involves the increase in size and number of cells, leading to an overall increase in tissue size.

The given correct answer is A because the characteristics listed in the options describe a newborn baby. A newborn baby is unable to control their body parts, completely dependent on their parents, unable to control their emotions, and can focus their vision.

The correct answer is 1), 2), dan 3). This is because auxin, gibberellin, and cytokinin are all plant hormones that play important roles in the growth and development of plants, including the normal growth of stems and roots. These hormones regulate various processes such as cell elongation, cell division, and differentiation, which are essential for plant growth. Therefore, providing these hormones is necessary for normal plant growth.

Asam absisat adalah hormon pada tumbuhan yang berperan besar dalam mengatur respons tumbuhan terhadap kondisi cuaca buruk seperti kekeringan. Hormon ini membantu tumbuhan mengatur penutupan stomata untuk mengurangi kehilangan air melalui penguapan dan juga merangsang produksi protein khusus yang membantu tumbuhan bertahan dalam kondisi lingkungan yang tidak menguntungkan.

Akar tanaman dapat terus tumbuh ke bawah tanah karena adanya pengaruh hormon auksin. Auksin adalah hormon pertumbuhan yang mempengaruhi pertumbuhan akar, termasuk pertumbuhan ke bawah tanah. Hormon auksin merangsang pemanjangan sel, sehingga akar dapat terus tumbuh ke bawah tanah.

Hormon gibberelin berfungsi untuk pertumbuhan tunas.

Sitokinin is a plant hormone that promotes cell division and growth. In this context, it is mentioned that sitokinin can be used to delay flower abscission. The option "memacu pertumbuhan kuncup pada pucuk" translates to "stimulating the growth of buds at the shoot". This aligns with the idea that sitokinin promotes growth, including the growth of buds, which can delay flower abscission. Therefore, this option is the correct answer.

Based on the given options, the correct answer is Kotiledon. The question asks to identify the number 3 in the given image, and the correct answer is Kotiledon.

The correct answer is Hipokotil because the image shows the part of the plant embryo that develops into the root. The hipokotil is the embryonic root of a plant, which grows downward into the soil to anchor the plant and absorb water and nutrients.

Antokalin adalah hormon tumbuh yang diperlukan untuk mempercepat perkembangan bunga.

The correct answer is sitokinin. Sitokinin is a plant hormone that promotes cell division and growth. It is responsible for stimulating the formation of lateral buds, which are the side shoots or branches that develop from the main stem of a plant. In the given image of a coffee tree, the presence of numerous lateral buds suggests that there is a high level of sitokinin present, as it is promoting the growth of these side shoots.

The correct answer is "kalin" because kalin is a hormone that is responsible for wound healing and tissue regeneration in plants. When a tree is cut or damaged, kalin helps in the formation of callus tissue, which covers the wound and promotes the growth of new cells. In this scenario, the tree was cut and the bark was removed, and after a few months, the area was covered and a bulge was visible, indicating tissue regeneration. Therefore, kalin is the hormone that is working in this situation.

The correct answer is B. The explanation for this answer is that the process of aging in women is marked by the weakening and thinning of the enamel layer of the teeth, which leads to tooth decay and loss. This is a common sign of aging and can be attributed to the decline in overall health and the body's ability to maintain and repair itself as it ages.
