Plant Biology - 5th Grade - Quiz

This quiz tests basic knowledge of cell structure and functions of different structures.


Questions and Answers
  • 1. 

    This picture shows a __________.

    • A.

      Animal cell

    • B.

      Plant cell

    • C.

      Planet

    • D.

      Sun

    Correct Answer
    B. Plant cell
    Explanation
    This picture is most likely showing a plant cell because it has characteristics such as a cell wall, chloroplasts, and a large central vacuole. These features are unique to plant cells and distinguish them from animal cells. Additionally, the shape and arrangement of the organelles in the picture resemble those commonly found in plant cells.

  • 2. 

    The green outer part of this picture is called the ____________.

    • A.

      Cell hallway

    • B.

      Cell envelope

    • C.

      Cell wall

    • D.

      Cell panel

    Correct Answer
    C. Cell wall
    Explanation
    The green outer part of the picture is referred to as the cell wall. The cell wall is a rigid layer that surrounds and supports the cell, providing structural integrity and protection. It is primarily composed of cellulose in plant cells and peptidoglycan in bacterial cells. The cell wall helps maintain the shape of the cell and prevents it from bursting or collapsing under pressure.

    The brown linning just inside the outer part of the cell is called the _____________.

    • A.

      Cell membrane

    • B.

      Cell brown part

    • C.

      Cell sheet

    • D.

      Cell roof

    Correct Answer
    A. Cell membrane
    Explanation
    The brown lining just inside the outer part of the cell is called the cell membrane. The cell membrane is a thin, flexible barrier that surrounds the cell and separates its internal environment from the external environment. It regulates the movement of substances in and out of the cell, allowing nutrients to enter and waste products to exit. The cell membrane also plays a crucial role in maintaining the cell's shape and providing protection.

    Rate this question:

  • 4. 

    The purple structure is the __________.

    • A.

      Cell ball

    • B.

      Barney

    • C.

      Neptune

    • D.

      Nucleus

    Correct Answer
    D. Nucleus
    Explanation
    The correct answer is "nucleus". The question is asking for the identification of the purple structure. Among the given options, the nucleus is the most plausible answer as it is a distinct organelle found in eukaryotic cells, typically stained purple in microscopic images. The other options, such as "cell ball," "Barney," and "neptune," do not make sense in the context of cell structures. Therefore, the purple structure is likely to be the nucleus.

    Rate this question:

  • 5. 

    The arrows pointing up through the stem are showing the ______________.

    • A.

      Xylophone

    • B.

      Stem

    • C.

      Xylem

    • D.

      Root

    Correct Answer
    C. Xylem
    Explanation
    The arrows pointing up through the stem are showing the movement of water and nutrients through the xylem. The xylem is a specialized tissue in plants that transports water and minerals from the roots to the rest of the plant.

    Rate this question:

  • 6. 

    The black arrow is pointing to arrows that are flowing down through the stem. This structure is called the ______________.

    • A.

      Branch

    • B.

      Phloem

    • C.

      Stem

    • D.

      Plate

    Correct Answer
    B. Phloem
    Explanation
    The black arrow is pointing to arrows that are flowing down through the stem. This structure is called the phloem. The phloem is responsible for transporting sugars and other organic compounds from the leaves to other parts of the plant, including the roots.

    Rate this question:

  • 7. 

    Label the plant parts from bottom to top:  (separate each part by a comma)

    Correct Answer
    root, leaf, stem, flower
    Explanation
    The given answer lists the plant parts in the correct order, starting with the root, followed by the stem, leaf, and flower. It is repeated again in the same order. This indicates that the answer is correctly identifying the sequence of plant parts.

    Rate this question:

  • 8. 

    Label the structures in the diagram below:

    Correct Answer
    Flower, fruit, seed, leaf, stem
    Explanation
    The diagram shows various parts of a plant. The flower is the reproductive structure of the plant, responsible for producing seeds. The fruit is the mature ovary of the flower, which contains the seeds. The seed is the reproductive unit of the plant, containing an embryo and stored nutrients. The leaf is the main site of photosynthesis, where the plant produces food. The stem provides support for the plant and transports water, nutrients, and sugars between the roots and leaves.

    Rate this question:

  • 9. 

    The picture below shows a magnified version of the underside of a leaf. The little holes are called stomata. This is the site of transpiration. Describe what happens during transpiration.
