are cell membranes found in plants
Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes. Plant and animal cells are both eukaryotic cells, so they have several features in common, such as the presence of a cell membrane, and cell organelles, like the nucleus, mitochondria and endoplasmic reticulum. In a plant cell it is located just inside of the cell wall (outer layer). In an animal cell, the cell membrane is the outer layer. + 44 others found this useful. Plasma Membrane – Plant Cells. The plasma membrane is a selectively permeable membrane made up of a lipid bilayer and proteins surrounding the cell but inside the cell wall. Explore the process, structure, and function of a plant cell’s plasma membrane with this interactive tutorial. Chapter: Cell Membranes. Cell Wall. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall. When looking under a microscope, the cell wall is an easy way to distinguish plant cells. 1 Cholesterol molecules are selectively dispersed between membrane phospholipids. 2  This helps to keep cell membranes from becoming stiff by preventing phospholipids from being too closely packed together. 3  Cholesterol is not found in the membranes of plant cells. A cell membrane is found in animal cells, but other parts, like … chloroplasts and cell walls are found in plant cells. Plant cells are eukaryotic cells, or cells with a membrane-bound nucleus. Unlike prokaryotic cells, the DNA in a plant cell is housed within the nucleus. In addition to having a nucleus, plant cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. 1 Cholesterol is not found in the membranes of plant cells. 2  Glycolipids are located on cell membrane surfaces and have a carbohydrate sugar chain attached to them. 3  They help the cell to recognize other cells of the body. 4  Cell Membrane Proteins. 5  Structural proteins help to give the cell support and shape. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape. Animal cells, plant cells, prokaryotic cells, and fungal cells have cell membranes. A plant cell also contains structures not found in an animal cell. Some of these include a cell wall, a large vacuole, and plastids. Plastids, such as chloroplasts, assist in storing and harvesting needed substances for the plant. Animal cells also contain structures such as centrioles, lysosomes, and cilia and flagella that are not typically found in plant cells.
