What is outer covering of plant cell?

cell wall
The cell wall is the outermost covering of a cell, present only in plant cells. It is made up of pectin, hemicellulose, cellulose microfibrils, and proteins organized into two layers – primary cell wall and middle lamella.

Which is the outermost layer of epidermis in plants?

What is the outer protective layer of the plant?

epidermis
The dermal tissue system—the epidermis—is the outer protective layer of the primary plant body (the roots, stems, leaves, flowers, fruits, and seeds). The epidermis is usually one cell layer thick, and its cells lack chloroplasts.

What is the outer covering of an animal cell called?

The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

Which tissue is responsible for the length of the plant?

Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Apical meristems are found at the apex, or tip, of roots and buds, allowing roots and stems to grow in length and leaves and flowers to differentiate.
