    Question: The flexibility in plants is due to a tissue called

    Options:

    Parenchyma
    Collenchyma
    Sclerenchyma
    None of these

    The correct answer is Collenchyma.

    •  📌Concept:
    -Collenchyma is a specialized simple permanent tissue that provides support and flexibility to plants.
    -This tissue is made up of living cells having uneven thickenings of cellulose, pectin, and hemicellulose on the walls.
    -Cells possess chloroplast, then it is involved in manufacturing sugar and starch.
    -Provides tensile strength and flexibility to the plant body.

    ✅Explanation:
    -Parenchyma- this tissue provides support to plants. It also stores food. So this option is not correct.
    -Collenchyma- it allows easy bending of plant parts and provides flexibility. So the option is correct.
    -Sclerenchyma- this tissue makes the plant hard and stiff. It is present in the husk of a coconut. So the option is not correct.

    🔴Additional Information:
    -Parenchyma is the most common and abundant tissue in plants which is made up of thin-walled living cells having a distinct nucleus.
    -The main function of parenchyma is to store and assimilate food. Hence, they are referred to as food storage tissues.
    -Serves as a packing tissue to fill the spaces between other tissues and maintain the shape and firmness of the plant.
    -Stores waste products of plants.
    -Sclerenchyma is a lignified supportive tissue made up of thick-walled and lignified cells.
    -Provides mechanical strength to the plant.
