  • Question 1/5
    1 / -0.33
    Which tissue conducts food and water from one part of the plant to other parts?
    Solutions

    Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally.

    Hence, option A is correct.

  • Question 2/5
    1 / -0.33
    Which of the following is the only living tissue in plant xylem is?
    Solutions
    • Xylem is one of the two types of transport tissue in vascular plants, phloem being the other.
    • The basic function of xylem is to transport water from roots to shoots and leaves, but it also transports some nutrients.
    • The tracheids, the trachea and the xylem fibers are non-living components, while xylem parenchyma represents the only living component of the tissue.
  • Question 3/5
    1 / -0.33
    Which of the following tissue transport food to various parts of a plant?
    Solutions

    Phloem is the vascular tissue responsible for the transport of food from source tissues.

    • Sclerenchyma, parenchyma, sieve elements and companion cells are some of the cell types from which Phloem is formed.

    • Xylem transport water from roots to stems in plants.

  • Question 4/5
    1 / -0.33
    Which tissue mainly provides mechanical strength to the growing plant parts?
    Solutions

    ● The tissue which provides support and mechanical strength to a plant or a growing organ in a plant is known as a Collenchyma.

    ● Collenchyma cells are usually living, and have only a thick primary cell wall made up of cellulose and pectin.

  • Question 5/5
    1 / -0.33
    Exchange of gases occurs through which part of the plant tissue?
    Solutions

    ● Exchange of gases in plants occurs through the tiny pores present on the surface of leaves. These pores are surrounded by guard cells. Such pores are called stomata. It allows the plant to take in carbon dioxide and gives out oxygen for photosynthesis.

    ● Transportation of food nutrients such as glucose and amino acids is carried out by the phloem tissues and water and soluble mineral nutrients are transported by xylem.
