Some of these structures release energy, while others produce proteins, transport substances, and control cellular activities. Collectively, these structures are called organelles.
Review your understanding of cell parts and functions in this free article aligned to NGSS standards. Key points: All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out.

Some cells are covered by a cell wall, other are not, some have slimy coats or elongated structures that push and pull them through their environment.
Puntos más importantes: Todas las células tienen una membrana celular que separa el interior y el exterior de la célula, y controla lo que entra y lo que sale. La membrana celular rodea el citoplasma de la célula, que es una sustancia gelatinosa que contiene las partes de la célula. Las células tienen partes llamadas organelos.

A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
So, let's take a look at some of the structures inside a cell and see how their functions come together to allow cells to carry out all the processes of life. So let's explore the parts of a cell starting with the cell's surface. Cells are separated from their outside environment by a cell membrane.
