All organisms are made up of one or more cells
Lysosomes and centrosomes function as a "garbage disposal" system. In which type of cells can these be found?
Animal cells
The cell membrane separates the interior of a cell from its external environment. Which cell type needs this?
Both eukaryotic and prokaryotic cells
Which of the following statements is the correct second principle of cell theory? 1) cell DNA is the base unit of life 2) cells are the structural and organizational unit of life 3) all organisms are composed of multiple cells 4) DNA is the structural and organizational unit of life
Cells are the structural and organizational unit of life
What is an organelle that can break down foreign matter and dead cells?
Centrosome
In addition to a cell membrane, what other features are universal to all cells?
Cytoplasm, DNA, and ribosomes
