Latihan Soal Pertumbuhan Dan Perkembangan (Online)

The correct answer is "hidroponik." Hidroponik refers to the method of growing plants without soil, using a nutrient-rich water solution instead. In this method, the plants' roots are submerged in the water solution, which provides them with all the necessary nutrients. This technique is commonly used in agriculture to maximize crop yield and conserve water resources.

The correct answer is "bersifat reversible atau dapat balik". This is because reversible or reversible processes refer to changes that can be undone or reversed. In the context of biological growth, reversible processes would imply that the growth can be reversed or the organism can return to its previous state. However, in the case of biological growth, the growth is typically irreversible, meaning that once an organism grows, it cannot revert back to its previous size or state.

The correct answer is "auksin". Auxin is a plant hormone that plays a crucial role in the growth and development of plants. It is responsible for various processes, including phototropism, which is the bending of plant stems towards a light source. When light is detected by the plant, auxin accumulates on the shaded side of the stem, causing cells to elongate and resulting in the bending of the plant towards the light. Therefore, auxin is responsible for the bending of the plant towards the direction of light.

Pertumbuhan sekunder adalah pertumbuhan yang terjadi pada bagian-bagian tanaman yang sudah matang, seperti batang dan akar. Xilem sekunder dan floem sekunder adalah dua jenis jaringan yang mengalami pertumbuhan sekunder. Xilem sekunder bertanggung jawab untuk mengangkut air dan mineral dari akar ke daun, sedangkan floem sekunder bertanggung jawab untuk mengangkut hasil fotosintesis dari daun ke bagian-bagian tanaman lainnya. Oleh karena itu, jawaban yang benar adalah xilem sekunder dan floem sekunder.

Plants require carbon from the air for the process of photosynthesis. During photosynthesis, plants use carbon dioxide from the air, along with water and sunlight, to produce glucose and oxygen. Carbon is a key component of glucose, which is the main source of energy for plants. Therefore, carbon is essential for plants to carry out photosynthesis and grow.

Zeatin adalah contoh hormon sitokinin. Hormon sitokinin bertanggung jawab dalam pertumbuhan dan pembelahan sel, serta pengaturan pertumbuhan tunas dan akar. Zeatin merupakan salah satu jenis sitokinin yang ditemukan dalam tumbuhan. Zeatin dapat merangsang pertumbuhan tunas, membantu dalam pembentukan bunga, serta meningkatkan pertumbuhan akar. Oleh karena itu, zeatin adalah jawaban yang tepat.

Cahaya mempercepat pertumbuhan tanaman adalah pernyataan yang benar karena tanaman membutuhkan cahaya untuk melakukan fotosintesis, yang merupakan proses penting dalam pertumbuhan tanaman. Cahaya merangsang produksi klorofil, yang digunakan oleh tanaman untuk menghasilkan energi yang diperlukan untuk pertumbuhan dan perkembangan. Tanpa cahaya yang cukup, tanaman cenderung tumbuh dengan lambat atau bahkan mati. Oleh karena itu, cahaya memainkan peran penting dalam mempercepat pertumbuhan tanaman.

The hormone auxin is responsible for the development and growth of fruits. By providing auxin hormone, seedless watermelons can be obtained.

Giberelin is the correct answer because it is a plant hormone that promotes plant growth and development. It can help in eliminating the dwarfing trait genetically in plants by stimulating cell elongation and division. Giberelin also plays a role in seed germination and flowering.

The correct answer is gas etilen. Ethylene is a plant hormone that plays a crucial role in leaf abscission, particularly during the dry season. It promotes the breakdown of cells in the abscission zone, which leads to the detachment and falling of leaves. This process helps plants conserve water during periods of drought and stress.
