Neither. The basic activities of life occur inside the cell
The basic activities of life occur in the cell. Cells are the smallest units of any living organism, and the smallest components of life itself.
They occur primarily and exclusively within the [confines of the] Living Cell.
All cells have three common features: a cell membrane (plasma membrane) that encloses the cell and controls what enters and exits, cytoplasm where cellular activities occur, and DNA that serves as the genetic material and contains instructions for cell function.
In both plant and animal cells there is a nucleus, cell membrane,cytoplasm A plant cell also has a cell wall and a permanent vacuole In both plant and animal cells there is a nucleus, cell membrane,cytoplasm A plant cell also has a cell wall and a permanent vacuole
Phospholipids.
Diffusion occurs on the cell membrane.
Not only Euglena, all living cells have cell membranes. This cell membrane is called as plasma membrane, which is a cell membrane. Plant cells have an additional outer membrane, called as cell wall, made up of cellulose. Animal cells lack cell wall but have plasma membranes. They also both have a Nucleus, which is the centre of a cell and controls all the cells activities.
There is no such thing as gytopplasm. BUt there is a cytoplasm is the parts of a cell that are enclosed within the plasma membrane. The cytoplasm is the site where most cellular activities occur, such as many metabolic pathways, and processes such as cell division.
the cell membrane
cell membrane (cell wall), nucleus, centrosome, protoplasm, and nuclear membrane these are the main parts...as for just 3, i guess you can pick The 3 basic cell parts are: 1. Plasma Membrane- The outer boundary of the cell. It controls what enters and exits the cell. 2. Cytoplasm- Portion of cell outside of the nucleus; is a semi-fluid cytosol with imbedded organelles. 3. A Control Center- Contains the DNA and controlls cell activities. In most cells this is a nucleus but not all.
it occurs in the cell membrane(through the cell membrane really)
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
