TPP/UCC109 Biology 3
, All cells
Are enclosed by a cell membrane
- keeps the internal environment separate from the
external environment
- enables homeostasis
Have DNA as their genetic information
- Chromosomes carry genes in the form of DNA, the
instructions for building the cell
Have cytosol
- a semiliquid gelatinous material within a cell in
which subcellular components are suspended
Have ribosomes
- organelle that is site of protein synthesis
- all cells require proteins
