1.) All organisms are made of cells.
2.) All existing cells are produced by other living thing.
3.) The cell is the most basic unit of life.
B.) Contributors to the Cell Theory:
People | Information | Hooke | He was the first to identify cells and he also named them. | Leeuwenhoek | He made better lenses so he observed cells in greater detail. | Schledien | He was the first to note that plants are made of cells. | Schwann | He concluded that all living things are made of cells. | Virchow | He proposed that all cells come from other cells. |
C.) Prokaryotic vs. Eukaryotic Prokaryotic Eukaryotic * Has a nucleus. * The largest organelle encloses the genetic information. * Can be multi-cellular.
* Does not have a nucleus. * DNA is suspended in the cytoplasm. * Are microscopic single-celled organisms.
* They can be single celled.
D.) Characteristics of all cells
E.) Cell Organelles Organelles | Function | Pictures | Cytoskeleton | A network of proteins that Are constantly changing to meet the needs of a cell. | | Nucleus | The storehouse for most of the genetic information in your cells. | | Endoplasmic Reticulum | An interconnected network of thin folded membranes. | | Ribosome | Tiny organelles that link amino acids together to from proteins. | | Golgi Apparatus | Consists of closely layered stacks of membrane enclosed spaces that process sort and deliver proteins. | | Mitochondria | Supply energy to the cell. | | Vacuole | A fluid filled sac used for the storage of materials needed by a cell. | | Lysosome | Membrane-bound organelles that contain enzymes. | | Centriole | Cylinder-shaped organelles mad of short microtubules arranged in a circle. | | Cell Wall | A rigid layer that gives protection, support, and shape to the cell. | | Chloroplast | Organelles that carry
