  • 2. 

    The root ,stem, leaves ,flower ,fruits are the various parts of-------

    • Flower

    • Stem

    • Plant

    • Option 4

    Correct Answer
    A. Plant
    Explanation
    The correct answer is "Plant" because all the mentioned parts (root, stem, leaves, flower, and fruits) are various components of a plant. Each part plays a specific role in the overall functioning and growth of a plant.

    Rate this question:

  • 3. 

    The part of the plant growing below the soil for support is called plumule

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The plumule is actually the embryonic shoot of a plant, which is located above the soil. The part of the plant that grows below the soil for support is called the root system. Therefore, the given statement is false.

    Rate this question:

  • 4. 

    The portions of the leaf attached to stem is called the leaf base

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The leaf base refers to the part of the leaf that is attached to the stem. It is the lowermost part of the leaf and provides support and attachment to the stem. The leaf base can vary in shape and size depending on the plant species. This is a true statement because the leaf base is indeed the portion of the leaf that is connected to the stem.

    Rate this question:

  • 5. 

    The tip of the leaf is called the leaf Apex

    • True

    • 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.

    Rate this question:

  • 6. 

    Is [your statement here] true or false?

    • True

    • False

    Correct Answer
    A. True
    Explanation

    Rate this question:

  • 7. 

    Flower may have a long or a short stalk called pedicle

    • True

    • 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.

    Rate this question:

  • 8. 

    Fenugreek and spinach has taproot while onion has------ root

    • Fibrous

    • Cap

    • Radical

    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.

    Rate this question:

  • 9. 

    The stalk of the flower is called

    • Pedicle

    • Filaments

    • Ovary

    • Option 4

    Correct Answer
    A. Pedicle
    Explanation
    The stalk of the flower is called a pedicle.

    Rate this question:

  • 10. 

    Seed which get divided into two parts are called monocotyledonous seed

    • True

    • False

    Correct Answer
    A. 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.

    Rate this question:

  • 11. 

    The parts of the stem between two nodes is called as

    • Bud

    • Node

    • Internode

    • Option 4

    Correct Answer
    A. Internode
    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.

    Rate this question:

  • 12. 

    The tip or the apical end of the stem is called

    • Nodes 

    • Bud

    • Internode

    • Option 4

    Correct Answer
    A. Bud
    Explanation
    The tip or the apical end of the stem is called a bud.

    Rate this question:

  • 13. 

    Thread like or fibre like root arising from the stem are called

    • Root hair

    • Fibrous root

    • Modified roots

    • Option 4

    Correct Answer
    A. 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.

    Rate this question:

  • 14. 

    Small leaf like structure may be present near the leaf base this are called-------

    • Stipule

    • Leaf base

    • Petiole

    • Option 4

    Correct Answer
    A. Stipule
    Explanation
    Stipules are small leaf-like structures that are often found near the base of a leaf. They can vary in shape and size and are usually found in pairs on either side of the leaf. Stipules can serve various functions, such as protecting the leaf bud or secreting nectar to attract insects. They are commonly found in many plant species and can be a useful characteristic for identification purposes.

    Rate this question:

  • 15. 

    The part that grow from inside the seed towards the soil called---------

    • Plumule

    • Radical

    • Root

    • Option 4

    • Option 5

    Correct Answer
    A. 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.
