Di bawah ini yang termasuk fungsi batang adalah ….
Correct Answer
C. Menyalurkan air dari akar ke daun
Explanation
The correct answer is "Menyalurkan air dari akar ke daun." This is because the function of the stem in a plant is to transport water and nutrients from the roots to the leaves. The stem acts as a conduit, allowing water to flow upwards through the xylem vessels. This process is essential for the survival and growth of the plant.
2.
Batang berkayu umumnya berwarna . . . .
Correct Answer
A. Coklat
Explanation
Batang berkayu umumnya berwarna coklat. This is because the color of wood is determined by the type of tree it comes from and the presence of certain pigments in the wood. Most types of wood have a natural brown color, which can range from light tan to deep chocolate brown. Therefore, it is reasonable to assume that the correct answer is coklat.
3.
Pertumbuhan batang mengarah ke . . . .
Correct Answer
B. Atas
Explanation
The growth of the stem is directed upwards, towards the top. This is because the stem of a plant contains cells called meristems, which are responsible for growth and development. These meristems are located at the tips of the stem and produce new cells that elongate and push the stem upwards. This upward growth allows the plant to reach towards sunlight, which is essential for photosynthesis.
4.
Stomata terdapat pada ….
Correct Answer
D. Daun
Explanation
Stomata are tiny openings found on the surface of leaves. They play a crucial role in the process of photosynthesis by allowing the exchange of gases, such as oxygen and carbon dioxide, between the plant and the environment. Stomata also help regulate the water balance of the plant by controlling the loss of water vapor through transpiration. Therefore, it is accurate to say that stomata are present in leaves.
5.
Alat kelamin betina pada tumbuhan adalah ….
Correct Answer
C. Putik
Explanation
The correct answer is "Putik". In plants, the female reproductive organ is called the pistil, which consists of several parts including the stigma, style, and ovary. The putik refers specifically to the stigma and style, which are responsible for receiving pollen and facilitating fertilization. The other options, such as kepala sari (an incorrect term), benang sari (referring to the male reproductive organ), and batang sari (referring to the filament of the stamen) are not related to the female reproductive organ in plants.
6.
Apa fungsi mahkota bunga ?
Correct Answer
A. Menarik perhatian serangga
Explanation
The correct answer is "Menarik perhatian serangga". The function of a flower crown is to attract insects, particularly pollinators like bees and butterflies, to the flower. The bright colors and fragrances of the flower crown act as signals to attract these insects, which then help in the process of pollination.
7.
Di bawah ini yang memiliki tulang daun menjari adalah ….
Correct Answer
C. Singkong
Explanation
The correct answer is Singkong because the question asks which of the options has a leaf with a finger-like shape. Singkong, also known as cassava, has leaves that are palmately compound, meaning the leaflets radiate from a single point like fingers on a hand. The other options, such as Mangga (mango), Nangka (jackfruit), and Sirih (betel leaf), do not have leaves with this characteristic.
8.
Tumbuhan rambutan bertulang jari
Correct Answer
A. Menyirip
Explanation
The correct answer is "Menyirip." Menyirip refers to the leaf arrangement in which the leaves are arranged in pairs on opposite sides of the stem. This arrangement is common in plants with pinnately compound leaves, where multiple leaflets are attached to a central axis. The term "bertulang jari" suggests that the leaves of the rambutan plant have a palmate venation, meaning the veins radiate outwards from a central point, resembling the fingers of a hand. Therefore, the most suitable leaf arrangement for a plant with palmate venation would be menyirip.
9.
Tempat pembuatan makanan pada tumbuhan adalah . . . .
Correct Answer
D. Daun
Explanation
The correct answer is "Daun". In plants, the process of photosynthesis takes place in the leaves. This is where the plant converts sunlight, water, and carbon dioxide into glucose and oxygen. The leaves contain chlorophyll, which is responsible for capturing sunlight and initiating the photosynthesis process. Therefore, the leaves are the primary location for food production in plants.
