Detailed explanation-1: -The epidermis protects the plant from infection and water loss. It regulates the gas exchange in plant cells. The epidermis regulates the secretion of metabolic substances. The epidermis is in charge of absorbing water and essential minerals.

Detailed explanation-2: -Sclerenchyma cells are generally found in nongrowing parts of the plant to add structural support to them. For example, sclerenchyma cells can be found supporting the vascular bundles in a stem, the plant tissues responsible for transport.

Detailed explanation-3: -Most flowers have four main parts: petals, sepals, stamens, and a pistil. Each flower part plays an important role in a plant’s ability to produce more of its kind. Pollination is the transfer of pollen grains from stamen to pistil. With few exceptions, pollination must take place before seeds can form.

Detailed explanation-4: -Plants have a root system, a stem or trunk, branches, leaves, and reproductive structures (sometimes flowers, sometimes cones or spores, and so on).
