| Question | Answer |
|---|---|
| What does a plasma membrane do? | protects supports the cell |
| What is the structure of the plasma membrane? | fluid mosaic composed of double lipid bylayer |
| plasma membrane heads are __ and point __ the aqueous fluid, while tails are ___ and point___ from aqueous fluid. | *Hydrophilic/towards *Hydrophobic/away |
| membrane proteins are anchored by _____ in the cytoplasm | Protein filaments |
| what are the three types of membrane proteins? | transport, recognition, receptor |
| Transport protein: | allows H20 soluble molecules through plasma membrane (salt, sugar, AA) |
| Receptor protein: | have binding sites for chemicals that alter overall cell function |
| Recognition protein: | have sugar groups on outside of cell, used by immune system to identify cells as self. |
| simple diffusion: | passive |
| Osmosis: | passive |
| Pinocytosis: | active |
| facilitated diffusion: | passive |
| Pinocytosis refers to engulfing ____ and phagocytosis engulfs _____ | *liquid *solid |
| 5 things all cells have in common: | plasma membrane, DNA, cell cytoplasm, obtain energy/nutrients from enviroment, function limits size |
| Mitochondria: | Produce energy |
| site of protein synthesis: | Ribosome |
| synthesizes lipids: | Smooth endoplasic reticulum |
| Synthesizes protein: | rough endoplastic reticulum |
| Digests excessive membrane: | Lysosome |
| 3 differences in cilia from flagella | shorter, more, move with perpendicular force |
| cilia and flagella both contain cytoskeletal elements made of ___ | Microtubles |
| synthesizes microtubules: | centrioles |
| plasma membrane: | Protects and supports the cell |
| flagella : | facilitates movement |
| Golgi apparatus: | sorts, modifies, and packages |
| Nucleus: | synthesizes ribosomes |
| The nucleus is made up of : | DNA, RNA, PROTEIN |
| ___ are the relaxed forms of DNA | Chromatins |
| Nuclear envelope: | (double membrane) Regulates movement of materials to/from the nucleus |
| Steroids are made of____ | Lipids |
| Nuclear pore: | Gate keeper |
| Intermediate filaments: | maintain cell shape/Integrity |
| What is the nucleus made up of? | plasma membrane, nuclear pores, chromatin, nucleus |
| osmosis: | passive movement of water |
| Diffusion: | High to low concentration |
| RBC's are still considered cells because they once had a _____ | nucleus |
| ____ and ___ are the effects of having no nucleus | *can't divided *cant synthesize |
| A lack of mitochondria is an advanage due to increased ____ carrying capacity | O2 |
| What are the 2 types of transport across cell membranes? | *Cell transport *energy requiring transport |
| Hypertonic: | concentration outside the cell is greater than inside (cell shrinks) |
| Isotonic: | same concentration in /out of the cell |
| Hypotonic: | concentration outside the cell is lower (cell swells) |
| Simplest cell is a ______ | Prokaryotic |
| a cells _____ differentiates us from bacteria | membrane bound nucleus |
| Prokaryotic cells are found in what 2 groups of single celled organisms? | bacteria and archaea |
| Eukaryotic cells are found in ___ and ___ | *People and plants |
| Eukaryotic cells are ___ in size compared to Prokaryotic cells and also contain a ____ | *larger *nucleus |
| Molecules are moved by ___ | Vesicles |
| Difference in animal and plant cells: | Cell wall, central vacule, chloroplast |
| Prokaryotic cells do not have ____ or ___ while Eukaryotic cells do. | *Microtubules *Nucleus |
