    How many cotyledons does a dicot contain?

    • One

    • Two

    • Three

    • Four

    Correct Answer
    A. Two
    Explanation
    Dicots, also known as dicotyledons, are a type of flowering plant that typically have two cotyledons or seed leaves. These cotyledons are present in the embryo of the seed and serve as a source of nutrients for the developing plant. Therefore, the correct answer is "two" because dicots generally have two cotyledons.

    During photosynthesis, carbon dioxide enters the leaf through the

    • Stomata

    • Rhizoids

    • Guard cells

    • Rhizomes

    Correct Answer
    A. Stomata
    Explanation
    Stomata are small openings located on the surface of leaves that allow for the exchange of gases, including the entry of carbon dioxide. These openings can be regulated by guard cells, which control the opening and closing of the stomata. Rhizoids are root-like structures found in non-vascular plants, rhizomes are underground stems, and guard cells are specialized cells that surround the stomata. Therefore, the correct answer is stomata.

    The union of the sperm and the egg is called

    • Germination

    • Transpiration

    • Pollination

    • Fertilization

    Correct Answer
    A. Fertilization
    Explanation
    Fertilization is the correct answer because it refers to the process of the union of the sperm and the egg. During fertilization, the sperm penetrates the egg, resulting in the formation of a zygote, which then develops into an embryo. This process is essential for sexual reproduction in organisms. Germination, transpiration, and pollination are unrelated processes that do not involve the union of sperm and egg.

    Plant tissue that carries food substances down from the plants leaves is called

    • Stoma

    • Cambium

    • Phloem

    • Xylem

    Correct Answer
    A. Phloem
    Explanation
    Phloem is the plant tissue that carries food substances down from the plant's leaves. It is responsible for the transportation of sugars, amino acids, and other organic compounds from the leaves, where they are produced through photosynthesis, to other parts of the plant. This tissue consists of specialized cells called sieve tubes, which are connected end to end to form a continuous pathway for the movement of food substances. The phloem plays a vital role in the distribution of nutrients throughout the plant, ensuring its growth and development.

    The leaf of a fern is called a

    • Frond

    • Rhizehome

    • Fiddlehead

    • Biennial

    Correct Answer
    A. Frond
    Explanation
    A fern leaf is called a frond because fronds are the large, divided leaves that are characteristic of ferns. These fronds are often highly intricate and can vary in shape and size depending on the species of fern. They are responsible for photosynthesis and reproduction in ferns. The term "frond" is commonly used to describe the leaf-like structures of ferns and is widely recognized in the field of botany.

    Angiosperms produce

    • Cones

    • Uncovered seeds

    • Covered seeds

    • Spores

    Correct Answer
    A. Covered seeds
    Explanation
    Angiosperms, also known as flowering plants, produce covered seeds. This means that the seeds are enclosed within a protective structure, such as a fruit or seed coat. This provides several advantages for the seeds, including protection from physical damage, desiccation, and predation. The covering also aids in seed dispersal, as fruits can be eaten by animals and the seeds are then transported to new locations. Covered seeds are a characteristic feature of angiosperms and contribute to their reproductive success and diversity.

    Which of these structures is not a stem?

    • Bulb

    • Rhizome

    • Frond

    • Tuber

    Correct Answer
    A. Frond
    Explanation
    A frond is not a stem. A frond is a large, divided leaf that is characteristic of ferns and palm trees. It is not a stem because it does not have the main functions of a stem, such as supporting the plant, transporting water and nutrients, and producing leaves and flowers. Instead, a frond is a specialized leaf structure that is involved in photosynthesis and reproduction.

    Auxins are

    • Enzymes

    • Sugars

    • Hormones

    • Fruits

    Correct Answer
    A. Hormones
    Explanation
    Auxins are a class of plant hormones that regulate various growth and developmental processes in plants. They play a crucial role in cell elongation, root formation, apical dominance, and tropic responses such as phototropism and gravitropism. Unlike enzymes and sugars, which are not involved in hormonal regulation, auxins act as chemical messengers, coordinating plant growth and development. Fruits, on the other hand, are the mature ovaries of flowering plants and are not directly related to auxins. Therefore, the correct answer is hormones.

    Ferns produce spores during

    • Germination

    • Fertilization

    • Sexual reproduction

    • Asexual reproduction

    Correct Answer
    A. Asexual reproduction
    Explanation
    Ferns produce spores during asexual reproduction. Unlike flowering plants that reproduce through seeds, ferns reproduce by releasing spores. These spores are produced in structures called sporangia, which are found on the underside of fern fronds. When the spores are released, they can germinate and develop into new fern plants without the need for fertilization or the involvement of gametes. This process of asexual reproduction allows ferns to efficiently spread and colonize new areas.
