Answer 2

Answer:

A plant part which is green when young and becomes woody and dark brown when it gets older is the stem.

Explanation:

• The epidermal cells in the stem are fresh, lively, and green when it is young.
• Because of the cellulose deposition and hardness, the cells become brownish as they mature.
• As a result, as the cells mature, they become lifeless and seem woody.
• The wood (dead cells) acts as a support for trees and plants, allowing them to stand upright.
• It guards against excessive sweating.
• It aids plants in surviving in cold climates by protecting them from snow.
• In cold areas, for example, woody plants survive the winter or dry season above ground, but herbaceous plants die back to the ground until spring.

Hence, the stem is green when young and it turns dark brown and woody when it matures.
