Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of this tissues support the young plants and woody plants?
A
collenchyma tissue
B
parenchyma tissue
C
sclerenchyma tissue
D
xylem tissue
Explanation: 

Detailed explanation-1: -Collenchyma is observed as supporting tissue in growing organs of numerous herbaceous and woody plants, and in mature stems and leaves of herbaceous plants, including those starting secondary growth. Collenchyma provides support for the grow of herbaceous stems, leaves and flowers of dicotyledon plants.

Detailed explanation-2: -Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.

Detailed explanation-3: -Collenchyma is a supporting tissue characteristic of the growing organs of many herbaceous and woody plants, and it is also found in stems and leaves of mature herbaceous plants, including those that are only slightly modified by secondary growth.

Detailed explanation-4: -It is primarily present in stems, leaves, flower parts and is the fundamental supporting tissue in many developed eudicot leaves and some green stems. Roots infrequently have Collenchyma however Collenchyma may happen in the cortex of the root if the root is presented to light.

Detailed explanation-5: -Collenchyma. Collenchyma cells have thick walls that are especially thick at their corners. These cells provide mechanical support for the plant. They are most often found in areas that are growing rapidly and need to be strengthened.
