    Correct Answer
    B. Bracts
    Explanation
    Poinsettias produce their color in the leaves below the flower called bracts. Bracts are modified leaves that are often brightly colored and attract pollinators. In the case of poinsettias, the bracts are the colorful parts that we commonly associate with the plant, while the actual flowers are small and inconspicuous. This is why poinsettias are often referred to as "flowering bracts."

    Correct Answer
    C. Terminal ends
    Explanation
    Pinching Poinsettias is a process of removing the terminal ends. This involves cutting or pinching off the top growth of the plant, which encourages branching and stimulates the growth of new shoots. By removing the terminal ends, the plant becomes bushier and more compact, resulting in a fuller and more attractive appearance. This technique is commonly used in the cultivation of Poinsettias to promote a desirable shape and size.

    Explanation
    Mealybugs are a common pest that affects poinsettias. They are small insects that feed on the plant sap, causing damage to the leaves and stems. They can also spread diseases to the plant. Therefore, mealybugs can be a significant problem for poinsettias, making them the correct answer in this case.

    Correct Answer
    B. 10-15
    Explanation
    The nighttime temperature of indoor plants should be 10-15 degrees cooler than that of the clay. This is because indoor plants require a slightly cooler temperature during the night to simulate their natural environment and promote healthy growth. If the temperature is too warm, it can lead to stress and damage to the plants. By maintaining a temperature difference of 10-15 degrees, the plants can rest and conserve energy during the night.

Codiaeum is a genus of plants in the family Euphorbiaceae, and some species within this genus are commonly referred to as crotons. Therefore, Codiaeum is the correct genus name for Croton.
