| Which was discovered first plant cells or Animal Cells | Plant |
| What did Anton van Leeuwenhoek observe | Animalcules (microorganisms |
| What did Rudolf Virchow determine | Cells come from pre-existing cells |
| What are the three statements of the cell theory | 1. all living organisms are made of one or more living cells 2. cells are the basic units of structure and function 3. cells come from pre-existing cells |
| What is the basic unit of life | the cell |
| cells are limited in size by their | surface area- to - volume ratio |
| what are the three basic parts of a cell | cytoplasm, control center, cell membrane |
| how are cell shape and function related | shape reflects function |
| why is small surface area-to- volume ratio ideal for cells | quick exchange of materials in and out of the cell |
| why is the mitochondria called the powerhouse of the cell | is makes ATP( energy) which powers the cellular functions |
| what do ribosomes do | make proteins |
| what is the role of the golgi body | processes and packages proteins and lipids |
| what is the function of lysosmes | digest food and bacteria and old cell parts |
| what is the function of the smooth ER and the Rough ER | smooth- builds and transports lipids rough - transport proteins |
| what types of cells lack a nucleus | prokaryotes |
| what do eukaryotic cells and prokaryotic cells dont | Nucleus and membrane bound organelles |
| membrane bound organelles are found in eukaryotes. give three examples of membrane- bound- organelles | ER, Mitochondria, Chloroplasts, Vesicles, Lysosmes, Nucleus, and Golgi Body |
| name two of the three parts that are found in plant cells and not in animal cells | Plastids (chloroplasts), Central Vacuole, Cell wall |
