cell membrane- a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell; proteins in the membrane control passage of ions (like sodium or potassium or calcium) in and out of the cell; "all cells have a cell membrane" ...
A simple diagram comparing an animal cell and plant leaf cell by domdomegg / CC BY (https://creativecommons.org/licenses/by/4.0) Essentially, a cell membrane is the outermost barrier that separates the internal contents of a cell in the cytoplasm from the external environment (e.g. separate...
cells are the structural, functional, and biological units of all living beings. a cell can replicate itself independently. hence, they are known as the building blocks of life . each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. also present in the cytoplasm ...
The cell cycle is a series of events that occur during the division of a cell. Explore the cell cycle definition and different phases of cell cycle only @ BYJU'S.
Large vacuole - Although the shape of palisade cells allows them to move when need be, the large vacuole located at the central part of the cell restricts chloroplasts to the area along the cell membrane. This ensures that light easily reaches the chloroplasts for photosynthesis to take place....
A cell membrane protects a cell and provides it structural support, but it is still necessary for the cell to interact with its outside environment. Along the surface of the cell, important proteins are arranged that facilitate these functions and help link individual cells to the community of ...
Most simple asphyxiants are harmful to the body only when they become so concentrated that they reduce oxygen in air (normally 21%) to dangerous levels (16% or lower). Asphyxiation is a potential hazard of working in confined spaces. Some chemicals like Carbon Dioxide function as chemical ...
Plasma Membrane Structure: Lipids and Plasma Membrane Fluidity Thefluid mosaic modelexplains the function and structure of a cell membrane. First, the membrane looks like a mosaic because it has different molecules inside like phospholipids and proteins. Second, the membrane is fluid because the molec...
Asimple epitheliumis an epithelial tissue that is composed of a single layer of epithelial cells. These cells are in direct contact with the basement membrane. This tissue may be classified histologically according to the shape of the cells it is made up of. It may be squamous (scale-like)...
trim - severely simple in line or design; "a neat tailored suit"; "tailored curtains" tailored plain - not elaborate or elaborated; simple; "plain food"; "stuck to the plain facts"; "a plain blue suit"; "a plain rectangular brick building" ...
