Describe the structure of a cell
WebThe cell wall and cell membrane are not the same thing. All cells have a cell membrane, but not all cells have a cell wall. Cell walls are very rigid, which makes the cell harder to move. They can be made up of a variety of substances, so cell walls in plant cells are different than those found in bacterial cells. WebWhat’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.
