Differences between animal and plant cells
 * **Animal Cells** || **Plant Cells** ||
 * lack cell walls (bursts more easily) || have cellulose cell walls (allow for higher pressure-> can accept water more easily without bursting) ||
 * heterotrophic: obtain energy from other living organisms or their dead remains || autotrophic: photosynthetic cells with cholroplasts ||
 * vacuoles small (one or more) || large, prominent central vacuole (one) ||
 * do not have a regular shape, very varied || have a regular shape ||
 * have centrioles, which help in cell division || do not have centrioles ||

Differences between eukaryotic and prokaryotic cells
 * **Eukaryote** || **Prokaryote** ||
 * relatively large cells (30-150um) || relatively small cells (0.5-10um) ||
 * have a double membrane bound nucleus, and organelles (internal membrane-bound structures) || only membrane is the cell membrane ||
 * have DNA enclosed in the nucleus || genetic material naked in the cytoplasm ||
 * can reproduce in many ways (eg. melosis, mitosis) || reproduce via binary fission ||
 * can be discrete, or exist in cell colonies, or as part of multicellular organisms (with specializations) || almost always single-celled, unless existing in colonies ||
 * fungal, protistan, animal, plant cells || bacterial cells ||
