What is the structure and function of the cell wall?
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
What are the main functions of cell wall?
The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell. A cell is the smallest part of an organism that still contains that organism’s elements.
What structure in animals carries out the function of the cell wall?
Animal cells and plant cells
|Mitochondria||Where most respiration reactions happen||Plant and animal cells|
|Vacuole||Contains a liquid called cell sap, which keeps the cell firm||Plant cells only|
|Cell wall||Made of a tough substance called cellulose, which supports the cell||Plant cells only|
What are the main components of an animal cell?
There are 13 main parts of an animal cell: cell membrane, nucleus, nucleolus, nuclear membrane, cytoplasm, endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrioles, cytoskeleton, vacuoles, and vesicles.
What is the basic structure of an animal cell?
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.
What is the structure of an animal cell?
Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall.
