A
Cell Membrane
B
Cell Wall
C
Autotroph
D
Heterotroph
Explanation: 

Detailed explanation-1: -Cell wall is a rigid covering present outside the plant cell which is composed of a complex structural substance called cellulose.

Detailed explanation-2: -Plant cells have a cell wall. The cell wall provides strength and support to the plant, much like the exoskeleton of an insect or spider. Our skeletons are inside our bodies, rather than on the outside like insects or spiders. The plant cell wall is mainly made up of the carbohydrates molecules cellulose and lignin.

Detailed explanation-3: -The Cell Wall A cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell. The cell wall contains not only cellulose and protein, but other polysaccharides a s well . The cell wall provides structural support and protection.

Detailed explanation-4: -Cells of bacteria, fungi, algae, and higher plants are surrounded by rigid cell walls, which are an integral part of the cell. Although not encased in cell walls, animal cells in tissues are closely associated with an extracellular matrix composed of proteins and polysaccharides.

Detailed explanation-5: -Cellulose. Cellulose molecules are long, unbranched chains of 1, 4-linked glucose units.
