Question

why dead cells are present in plants??

Answer 1

There are dead cells in the plants because they help to support and strengthen the tissues in the plants.. Some examples of tissues they strengthen are leaves and stem.

Answer 2

Plants do contain dead cells, they don’t have a mechanism for disposing of them, and they wouldn’t, anyway. A tree, for instance, uses dead cells to support itself while layers of new living cells are continuously produced. The dead cells in a tree are called heartwood. The heartwood is considered the pillar upon which a tree is supported, and it continues to increase in sectional diameter as layers of sapwood mature and die and are covered with new layers of living sapwood.

Other plant cells can die and stay attached to the plant, until the plant rejects them, or the decay and fall off. Leaves often dry out and shed as new foliage and branches develop, limbs may die and remain attached to trees for many years, and usually they have little effect on the plant’s health.
