and protozoa
All multicelled animals
2. Membrane-bound nucleus
3. Specialized organelles in cytoplasm
4. Reproduce by mitosis/cytokinesis, and meiosis
Compartmentalization - ANSWER Distinct sub-cellular compartments and
organizations that allow chemical reactions that require different environments
to occur simultaneously
Cell Theory - ANSWER 1. All organisms consist of one or more cells.
2. Cells are the smallest units characteristic of life.
3. All cells arise from pre-existing cells
Components of plasma membrane - ANSWER Complex lipid bilayer,
