Questions and Answers
  • 1. 

    Seeds are made by

    • A.

      Rain

    • B.

      Soil

    • C.

      Plants

    • D.

      Clouds

    Correct Answer
    C. Plants
    Explanation
    Seeds are made by plants through a process called reproduction. Plants produce flowers that contain reproductive organs, such as ovaries and stamens. These organs produce gametes, which are the male and female reproductive cells. Fertilization occurs when pollen from the stamen reaches the ovary, resulting in the formation of a seed. The seed contains the embryo of a new plant, along with a food source and a protective outer covering. Eventually, the seed is dispersed and can germinate in suitable conditions, giving rise to a new plant.

    Rate this question:

  • 2. 

    Which part of the plant takes up the nutrients and water?

    • A.

      Leaves

    • B.

      Roots

    • C.

      Seeds

    • D.

      Stem

    Correct Answer
    B. Roots
    Explanation
    The roots of a plant are responsible for taking up nutrients and water from the soil. They have specialized structures called root hairs that increase the surface area for absorption. The roots also anchor the plant in the ground and provide support. While leaves play a role in photosynthesis and seed production, they do not directly take up nutrients and water as the roots do. Similarly, the stem transports water and nutrients throughout the plant but does not absorb them. 

    Rate this question:

  • 3. 

    Which part of the plant carries food and water through the plant?

    • A.

      Stem

    • B.

      Roots

    • C.

      Leaves

    • D.

      Flower

    Correct Answer
    A. Stem
    Explanation
    The stem of a plant carries food and water through the plant. It is responsible for transporting water and nutrients from the roots to the leaves and for carrying food produced in the leaves to other parts of the plant. The stem also provides support for the plant and helps in the growth of new leaves, flowers, and fruits.

    Rate this question:

  • 4. 

    All plants have

    • A.

      Fruits

    • B.

      Flowers

    • C.

      Roots

    • D.

      None of these

    Correct Answer
    C. Roots
    Explanation
    Roots are a vital part of all plants as they anchor the plant to the ground and absorb water and nutrients from the soil. They also provide support and stability to the plant. Therefore, it can be concluded that all plants have roots.

    Rate this question:

  • 5. 

    Plants make their own

    • A.

      Water

    • B.

      Sunlight

    • C.

      Oxygen

    • D.

      Food

    Correct Answer
    D. Food
    Explanation
    Plants have the ability to produce their own food through a process called photosynthesis. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. Glucose serves as their food source, which they use for energy and growth. Oxygen is released as a byproduct of photosynthesis, which is essential for the survival of other organisms. Therefore, the correct answer is "Food."

    Rate this question:

  • 6. 

    ______ supports the flower.

    • A.

      Stem

    • B.

      Root

    • C.

      Leaves

    • D.

      None of these

    Correct Answer
    A. Stem
    Explanation
    The stem of a plant supports the flower. The stem is the main structural part of a plant that connects the roots to the leaves and flowers. It provides support and allows the flower to grow and reach sunlight for photosynthesis. The stem also transports water, nutrients, and sugars between the roots and leaves, enabling the flower to receive the necessary resources for growth and development.

    Rate this question:

  • 7. 

    Usually, the color of a leaf is

    • A.

      Blue

    • B.

      Green

    • C.

      Red

    • D.

      None of these

    Correct Answer
    B. Green
    Explanation
    Leaves are usually green due to the presence of a pigment called chlorophyll. Chlorophyll absorbs blue and red light while reflecting green light, which leaves its characteristic green color. This pigment plays a crucial role in photosynthesis, the process by which plants convert sunlight into energy. While some leaves may change color to red, orange, or yellow during the fall due to the breakdown of chlorophyll and the presence of other pigments, the natural and most common color of a leaf is green.

    Rate this question:

  • 8. 

    Which of these is not a part of a plant?

    • A.

      Leaves

    • B.

      Root

    • C.

      Branch

    • D.

      All of these are parts of a plant.

    Correct Answer
    D. All of these are parts of a plant.
    Explanation
    All of these options are parts of a plant. Leaves, roots, and branches are all essential components of a plant's structure and function. Leaves are responsible for photosynthesis, roots anchor the plant and absorb water and nutrients, while branches support the growth of leaves and flowers. Therefore, all of these options are correct and are indeed parts of a plant.

    Rate this question:

  • 9. 

    Which part of the plant carries and protects the seed?

    • A.

      Stem

    • B.

      Fruit

    • C.

      Roots

    • D.

      Flower

    Correct Answer
    B. Fruit
    Explanation
    Fruits are the part of a plant that carries and protects the seed. After pollination, the ovary of the flower develops into a fruit. The fruit provides a protective covering for the seed, preventing damage from external factors such as animals, insects, or harsh environmental conditions. Additionally, fruits often attract animals to consume them, aiding in seed dispersal and increasing the chances of successful reproduction for the plant. Therefore, fruits play a crucial role in carrying and protecting the seeds of a plant.

    Rate this question:

  • 10. 

    Which part of the plant allows it to reproduce?

    • A.

      Flower

    • B.

      Stem

    • C.

      Seeds

    • D.

      Roots

    Correct Answer
    A. Flower
    Explanation
    The part of a plant that allows it to reproduce is the flower. Flowers are the reproductive structures of angiosperms, which are the most diverse group of plants. Within the flower, you typically find the reproductive organs, including the male parts (stamens with pollen-producing anthers) and the female parts (carpels with the stigma, style, and ovary).
