Question | Answer |
Organelle DNA ? | found in chloroplast & mitochondria, its essential for normal function of these organelles |
the cell membrane is sometimes known as..? | lipid bilayer |
Cell membrane? | flexible barrier |
chloroplast? | contain chlorophyll to preform photosynthesis |
mitochondria? | power house of the cell |
example of active transport? | edocytosis, phagocytosis, exocytosis, pinocytosis |
active transport? | DOES require energy bc it involves movement from area of low concentration to an area of high concentration against the concentration grading |
aquaporins are a type of ...? | facilitated diffusion |
aquaporins | special water channel protiens that allow water into the cell |
diffusion | the movement of molecules across a membrane from high to low concentration |
osmosis | diffusion of water across a selectively permeable membrane/ will continue until equaliblium is reached |
hypotonic solution | concentration higher in cell ( water moves out, cell shrinks ) |
isotonic solution | equalibrium is achieved |
facilitated diffusion | some molicules must pass through the membrane using protien channels |
example of eurokaryotes? | fungi, protist, plant/animal cells |
example of prokaryotes? | bacteria |
eurkaryotes | larger, more complex cells, contain a nucleus & membrane bound organelle |
prokaryotes | small, simple cells that lack nucleus & membrane bound organelles |
in 1855, Rudoff Virchow said..? | " where a cell exist, there must have been a pre-existing cell " |
in 1839, Theodore Schwann said ..? | " all animals are made of cells " |
In 18_ _, who said " all plants are made of cells " | Mathia Schleiden, 1838 |
new cells are produced from...? | pre-existing cells |
_____ are the basic unit of structure & function in living things | cells |
all living things are composed of...? | cells |
in _____, who used a simple microscope to look at a thin slice of cork? | 1665, Robert Hooke |
who invented the single lens microscope & when? | Anton Van Leevenhook, 1600s |
golgi apparatus | uses enzymes to attach carbohydrates & lipids to protiens |
smooth ER? | without rybosomes |
rough ER? | covered with ribosomes |
endoplasmic reticulum ? | cell membrane componets are assembled & some protiens are modified |
ribosomes? | protien syntheis |
cytoskeleton? | supports |
lysosomes? | clean up & contain digestive enzymes |
vaccuoles & vesticles? | storage of water, salts, protien, and carbs |
chromosomes? | condensed chromaton contains genetic info visible when cells divide |
chromaton? | DNA bound to protien within the nucleus |
organelle? | " tiny organs " |
cytoplasm? | jelly-like, all organelles are suspended within |
nucleus? | control center, identified by Robert Hooke in 1831 |
nucleolus? | inside nucleus functions in the making of ribosomes |
