Detailed explanation-1: -The cell wall is a non-living, rigid membrane that is made up of cellulose. It provides mechanical strength and support to the cell. Tonoplast is the membrane surrounding the vacuole. Chloroplast is a plastid present in plant cells that help in photosynthesis.

Detailed explanation-2: -The cell wall is the outermost layer of a plant cell. It makes the cell stiff and gives it protection. Animal cells do not have cell walls. The cell membrane is a protective layer that surrounds every cell.

Detailed explanation-3: -The epidermis is the protective outer layer of clonally related cells covering all plant organs. It is composed of a number of specialised cell types which differentiate from the basal epidermal cell in adaptively significant frequencies and patterns.

Detailed explanation-4: -A strong, stiff nonliving layer outside the cell membrane; in plants, made of cellulose. It supports and protects the cell membrane. nucleolus. Small dark area in the nucleus where ribosomes, RNA and proteins are made.

Detailed explanation-5: -Plant cells are surrounded by a tough extracellular matrix in the form of a cell wall, which is responsible for many of the unique features of a plant’s life style.
