| CELL MEMBRANE | *support *protection *controls movement of materials in/out of cell *barrier between cell and its environment *maintains homeostasis |

| ROUGH ENDOPLASMIC RETICULUM | an interconnected network of flattened, membrane-enclosed sacs or tube like structures known as cisternae with ribosomes attached |
| SMOOTH ENDOPLASMIC RETICULUM | Transports and modifies organelles, highway for cell. Processes carbohydrates, lipids, fats and such. No ribosomes on this organelle |
| LYSOSOME | Contains digestive enzymes necessary for breaking down materials within a cell |
| MITOCHONDRIA | Provides energy to cell. Have a double membrane. The outside is smooth but the inner is highly folded to increase its surface area. Cellular respiration is performed here, making energy (ATP) for the cell. Has its own DNA and ribosomes - Powerhouse of the cell |
| CYTOSKELETON | Helps maintain cell shape. Its primary importance is in cell motility. It makes the cell move internally and externally. |
| EUKARYOTIC | An organism with cells characteristic of all life forms except primitive microorganisms such as bacteria |
| PROKARYOTIC | A single‐celled organism that lacks a membrane‐bound nucleus and specialized organelles. |
| NUCLEAR MEMBRANE/ENVELOPE | Double membrane that separates the nucleus from the rest of the cell. Contains nuclear pores that controls what goes in and out of the cell. |
| DNA | Hereditary information that gets passed on during reproduction. It also directs the cells activities while not dividing. Responsible for the production of proteins. |
| CILIA | MULTIPLE, SHORT, HAIR-LIKE PROJECTIONS OFF OF MANY TYPES OF ANIMAL CELLS FOR TRANSPORTING FLUIDS OR PARTICLES |
| FLAGELLA | SINGLE OR FEW, WHIP-LIKE PROJECTION OFF A CELL THAT AIDES IN MOVEMENT. |
| NUCLEOPLASM | Fluid in the nucleus. |
| PLASMA (CELL) MEMBRANE | Regulates what enters and leaves the cell. Defines the area of the cell. Separates the inside of the cell from the outside of the cell. |
| NUCLEUS | Contains the hereditary information (DNA). Controls the cell by providing the information to make specific proteins. |
| VESICLES | - Form by pinching off from other membranes. - Fuse with other membranes when they come into contact. - Used to transport materials. |
| ORGANELLE | cell parts with specialized function |
| CYTOSKELETON | A network of long protein strands in the cytosol that helps support the cell |
| CHROMATIN | A material in cells that contains DNA and carries genetic information |
| SMOOTH ENDOPLASMIC RETICULUM | responsible for the production and secretion of steroid hormones. |
| SMOOTH ENDOPLASMIC RETICULUM | functions for detoxification, which is the removal of all the toxic materials such as (metabolic wastes or drugs) |
| ROUGH ENDOPLASMIC RETICULUM | associated with protein synthesis and also plays a vital role in protein folding |
| CYTOLOGY | STUDY OF CELLS |
| ROBERT HOOKE | 1665 -English scientist that cut a thin slice of cork and looked at it under his microscope. To him, the cork seemed to be made up of empty little boxes, which he named cells |
| MATTHIAS SCHLEIDEN | 1838 German botanist who determined plants are composed of cells. |
| RUDOLF VIRCHOW | 1858 - A doctor who stated that all living cells come from other living cells (part 3 of the cell theory) |
| ANTON VAN LEEUWENHOEK | 1673 Dutch naturalist who created a very powerful (for the time period) single lens microscope, He observed pond water. In pond scum he discovered small animals he called animalcules,or little animals (protists),and also discovered bacteria while examining scraping of crud from his teeth. |
| EUKARYOTIC | An organism with cells characteristic of all life forms except primitive microorganisms such as bacteria |
| CELL | the basic structural and functional unit of all organisms |
| THEODORE SCHWANN | German physiologist, histologist, & zoologist who in 1838 and 1839 identified the cell as the basic structure of animal tissue (1810-1882) |
| PROKARYOTIC | A single‐celled organism that lacks a membrane‐bound nucleus and specialized organelles. |
| DNA | Hereditary information that gets passed on during reproduction. It also directs the cells activities while not dividing. Responsible for the production of proteins. |
| EU | true |
| PRO | before |
| KARY | nucleus |
| UNICELLULAR | single celled |
| MULTICELLULAR | many cells |
| CELL MEMBRANE | thin membrane that forms the outer surface of the protoplasm of a cell and regulates the passage of materials in and out of the cell |
| CYTOPLASM | fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol. |
| NUCLEUS | membrane-bound structure that contains a cell's hereditary information and controls its growth and reproduction. |
| PERMEABLE | having pores or openings that allow substances to pass through |
| CELL THEORY | -All living organisms are composed of cells. -Cells are the smallest unit of life -Cells come from pre-exsisting cells and cannot be created from non-living material. |
