      Radical

    • C.

      Root

    • D.

      Option 4

    • E.

      Option 5

    Correct Answer
    B. Radical
    Explanation
    The part that grows from inside the seed towards the soil is called the radical. This is the embryonic root of the plant and is responsible for anchoring the plant in the soil and absorbing water and nutrients. The radical is the first part of the plant to emerge during germination and plays a crucial role in the early development of the plant.

    • A.

      Root hair

    • B.

      Fibrous root

    • C.

      Modified roots

    • D.

      Option 4

    Correct Answer
    B. Fibrous root
    Explanation
    A thread-like or fiber-like root that arises from the stem is called a fibrous root. This type of root system is commonly found in monocot plants, where the primary root does not develop into a main taproot but instead produces a cluster of thin, branching roots. Fibrous roots help anchor the plant in the soil and absorb water and nutrients from a larger area.

    • E.

      Option 5

    Correct Answer
    A. Tap root
    Explanation
    Tap root is the correct answer because it is a type of root that supports plants. Tap roots are usually thick and go deep into the soil, providing stability and anchorage to the plant. They also help in absorbing water and nutrients from the soil. This type of root system is commonly found in dicotyledonous plants.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The tip of a leaf is indeed called the leaf apex. The apex refers to the pointed or rounded end of the leaf. It is the part of the leaf that is farthest from the point of attachment to the stem. This term is commonly used in botany to describe the morphology and structure of leaves.

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Flowers can indeed have a long or short stalk called a pedicle. The pedicle is the part of the flower that connects the flower to the stem or branch. It provides support and allows the flower to be elevated and easily visible to pollinators. Therefore, the statement "Flower may have a long or a short stalk called pedicle" is true.

      False

    Correct Answer
    B. False
    Explanation
    Monocotyledonous seeds do not get divided into two parts. Monocotyledonous seeds have only one cotyledon or seed leaf, while dicotyledonous seeds have two cotyledons. Therefore, the given statement is false.

    Explanation
    The parts of the stem between two nodes are called internodes. Nodes are the points on the stem where leaves, buds, or branches are attached. Internodes, on the other hand, refer to the sections of the stem that are found between these nodes. They are typically longer in length and do not have any attachments.

    Correct Answer
    A. Fibrous
    Explanation
    Fenugreek and spinach are both known to have taproots, which are thick and elongated roots that grow deep into the soil. On the other hand, onion has fibrous roots, which are thin and spread out in a network close to the surface of the soil. Fibrous roots are typically shallow and do not penetrate deeply into the ground like taproots. Therefore, the correct answer is "Fibrous" as it accurately describes the root system of an onion.
