    Which of the statement is true about a seed?

    • A seed is not a living thing and it cannot move

    • A seed is a living thing and can grow into seedling

    • A seed died when the fruit is eaten by animals

    • A seed can make its own food

    Correct Answer
    A. A seed is a living thing and can grow into seedling
    Explanation
    A seed is a living thing and can grow into a seedling. Seeds are the reproductive structures of plants and contain all the necessary genetic material and nutrients to develop into a new plant. They are capable of germination, where they absorb water and begin to grow roots, shoots, and leaves. This process allows the seed to develop into a seedling and eventually mature into a fully grown plant. Therefore, a seed is indeed a living thing and has the potential to grow into a new plant.

    Both spiders and insects have exoskeleton

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Both spiders and insects have exoskeletons, which is a hard outer covering that provides support and protection for their bodies. This exoskeleton is made of a tough substance called chitin. It serves as a protective barrier against predators and helps to maintain the shape and structure of the spider or insect. Having an exoskeleton also allows spiders and insects to move and interact with their environment effectively. Therefore, the statement that both spiders and insects have exoskeletons is true.
