31 de mar. de 2021 · Cell Parts and Functions. All cells contain specialized, subcellular structures that are adapted to keep the cell alive. Some of these structures release energy, while others produce proteins, transport substances, and control cellular activities. Collectively, these structures are called organelles. Plant and animal cells both contain ...

The plasma (cell) membrane separates the inner environment of a cell from the extracellular fluid. It is composed of a fluid phospholipid bilayer (two layers of phospholipids) as shown in figure 4.1.2 4.1. 2 below, and other molecules. Not many substances can cross the phospholipid bilayer, so it serves to separate the inside of the cell from ...
What’s found inside a cell. An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.
Introduction to the cell. Cells are the most basic unit of life. All cells have a membrane that separates them from the outside world. Although cells are small, they are not simple. Cells contain different components, such as the cytoplasm, ribosomes, and genetic information in the form of DNA. Created by Sal Khan.
Molecular Biology of the Cell is the classic in-depth text reference in cell biology. By extracting fundamental concepts and meaning from this enormous and ever-growing field, the authors tell the story of cell biology, and create a coherent framework through which non-expert readers may approach the subject. Written in clear and concise language, and illustrated with original drawings, the ...
