Test Your Knowledge On Plants - Quiz

Do you consider yourself a know-it-all when it comes to plants? Do you know how plants collect food and water? Check out our online quiz to test yourself and learn facts.


Questions and Answers
  • 1. 

    Which part of a plant helps keep the plant in an upright position?

    • A.

      Leaf

    • B.

      Flower

    • C.

      Roots

    • D.

      Stem

    Correct Answer
    D. Stem
    Explanation
    The stem of a plant helps keep the plant in an upright position. The stem provides structural support and contains specialized tissues that transport water, nutrients, and sugars throughout the plant. It also allows the leaves and flowers to be positioned for optimal sunlight exposure. Without a strong and sturdy stem, the plant would not be able to stand upright and would be more prone to falling over.

    Which part of a plant collects water and nutritions?

    • A.

      Fruit

    • B.

      Roots

    • C.

      Leaves

    • D.

      Stem

    Correct Answer
    B. Roots
    Explanation
    Roots are the part of a plant that collects water and nutrients from the soil. They have specialized structures, such as root hairs, that increase the surface area for absorption. The roots also anchor the plant in the ground, providing stability and support. In addition to water and nutrients, roots also store food and carbohydrates for the plant's growth and development.

  • 3. 

    Three things that plants need to grow are ________,________, and ________.

    Correct Answer
    water, sunlight, air
    Explanation
    Plants require water, sunlight, and air to grow. Water is essential for plants as it helps in transporting nutrients and minerals from the soil to different parts of the plant. Sunlight is necessary for photosynthesis, a process through which plants convert sunlight into energy. Air is needed for respiration, allowing plants to take in oxygen and release carbon dioxide. These three elements work together to provide plants with the necessary resources for growth and development.

  • 4. 

    All plants begins life as a ___________

    • A.

      Flower

    • B.

      Root

    • C.

      Leaf

    • D.

      Seed

    Correct Answer
    D. Seed
    Explanation
    Plants begin life as seeds, which contain the embryo of the plant. Seeds are the reproductive structures of plants and serve as a means of dispersal. They contain all the necessary nutrients and genetic information to initiate growth and development. Once a seed is planted in the soil and provided with proper conditions such as water, sunlight, and nutrients, it germinates and starts growing into a new plant. Therefore, the correct answer is seed.

    Talking about the plant cycle. What is the second step in the plant cycle is  ________,  Which is actually a starter of the growth for the plant.

    Correct Answer
    germinate, germination
    Explanation
    The second step in the plant cycle is germination. Germination is the process in which a seed begins to grow and develop into a new plant. It is the starter of the growth for the plant, as it involves the seed absorbing water and breaking out of its dormant state, leading to the emergence of a root and shoot system. This step is crucial for the plant's growth and is the beginning of its life cycle.

    What is that hardcover which is protecting embryo(baby plant) inside a seed?

    • A.

      Seed shell

    • B.

      Seed coat

    • C.

      Seed jacket

    • D.

      Dried seed

    Correct Answer
    B. Seed coat
    Explanation
    The hardcover that protects the embryo (baby plant) inside a seed is called the seed coat. The seed coat acts as a protective layer, shielding the delicate embryo from damage, moisture loss, and external threats. It is typically tough and durable, providing a barrier that helps the embryo survive until it is ready to germinate and grow into a new plant.

    Look at the picture and choose the best answer.

    • A.

      Compound

    • B.

      Simple

    The process by which a plant breath and make food is ________________.

    • A.

      Sunlight

    • B.

      Photosynthesis

    • C.

      Water

    • D.

      Chlorophyll

    Correct Answer
    B. Photosynthesis
    Explanation
    Photosynthesis is the correct answer because it is the process by which plants use sunlight, water, and chlorophyll to convert carbon dioxide into oxygen and glucose. During this process, plants take in carbon dioxide from the atmosphere through tiny pores in their leaves called stomata, and then use the energy from sunlight to convert it into oxygen and glucose. This process is essential for plants to produce their own food and release oxygen into the atmosphere.
