| Organelles | Answer |
|---|---|
| What does ER synthesize | involved in synthesis of protein |
| Rhibosomes whithin ER produce | primary structures which ER modifies later |
| ER does what with cellular substances | synthesizes, modifies, transport |
| what has no ribosomes and is used for trasnportation | smooth ER |
| what sort of ER is most often found in secretion cells such as the throat | smooth ER |
| In Rough ER, rhibosomes are | adhered to one side |
| Stacks of membranous, flattened sacs | Golgi bodies |
| charactersitics of the Golgi body | dynamic, always forming and diminishing, they continue the chemical functions of the ER |
| vescicles are | membrane bound vacuules |
| Lysosomes | contain digestive enzymes that are synthesizied by Golgi bodies |
| prokaryotic characteristics | simple, single cell forms of life, biochemically complex |
| what is an example of a prokaryotic organism | blue green algae (Monera) |
| prokaryotic bacteria have | many structures on the inside, many ribosomes, DNA |
| EUKARYOTIC | TRUE NUCLEAS |
| EUKARYOTIC HAVE | NUMEROUS MEMBRANE SURROUNDED ORGANELLES, |
| EXAMPLES OF EUKARYOTIC ORGS: | PROTISTA, PLANTAE, ANIMALIEA |
| SIMILIAR CELLS COMBINE TO FORM | TISSUES, ORGANS. SYSTEMS, ORGANISMS |
| 7 Fx of a cell | synthesis, assimilation, digestion, transportation, energy transformation, responses, movement (SAD TERM) |
| two types of transport | passive and active |
| cells are | organized, living, membranous, have a variety structures |
| cell theory | all organisms have at least 1 cell, cell = basic unit of life, and all cells come from pre existing cells |
| plant cell vs animal | plants have cell wall & membrane, animal just membrane |
| plant chemicals vs animal chemicals in a cell | plant cytoplast chloroplast animals = sentioles |
| cilia | hairs for movement |
| flagella | whip like chord for movement |
| plasma membrane organelle does : | seperates internal/external; selectively permeable, |
| plasma membrane is made of | proteins and phospholipids, make a bi lipid layer |
| microtrabecular lattice | skeleton of cell |
| microtrabecular lattice is a | maze like network of hollow fibers that connects and supends organelles |
| cyto skeleton is also called | microtrabecular lattice, or cytoplasmic matrix |
