GENERAL HISTOLOGY

Detailed explanation-1: -Final answer : The two structures found in plant cells that are absent in animal cells are cell wall and chloroplast.

Detailed explanation-2: -Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.

Detailed explanation-3: -A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary cell wall, the middle lamella, and the secondary cell wall (not pictured).

Detailed explanation-4: -The organelles found only in plant cells include-chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.
