The Cell Wall. If you examine Figure 4.8b, the diagram of a plant cell, you will see a structure external to the plasma membrane called the cell wall. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Fungal and protistan cells also have cell walls.
Cytoplasm is a clear substance that is gel-like in the cell membrane but is on the outside of the nucleus. It contains mostly water with the addition of enzymes, organelles, salts and organic molecules. Cytoplasm will liquefy when it is stirred or agitated. It is often referred to as cytosol, meaning "substance of the cell."Animal cells do not have a cell wall. When looking under a microscope, the cell wall is an easy way to distinguish plant cells. Chloroplasts . Plants are autotrophs; they produce energy from sunlight through the process of photosynthesis, for which they use cell organelles called chloroplasts. Animal cells do not have chloroplasts. A chloroplast, as a distinct and essential organelle within plant and algal cells, plays a pivotal role in the process of photosynthesis. This membrane-bound plastid possesses the photosynthetic pigment chlorophyll, which is the principal agent responsible for capturing solar energy.The Chloroplast Is One Member of the Plastid Family of Organelles. Chloroplasts are the most prominent members of the plastid family of organelles. Plastids are present in all living plant cells, each cell type having its own characteristic complement. All plastids share certain features.Chloroplasts are surrounded by a double membrane similar to the double membrane found within a mitochondrion. Within the chloroplast is a third membrane that forms stacked, disc-shaped structures called thylakoids. Embedded in the thylakoid membrane are molecules of chlorophyll, a pigment (a molecule that absorbs light) through which the entire ...

Chloroplasts and Photosynthesis - Molecular Biology of the Cell - NCBI Bookshelf All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape.
