Cells chapter 6 Flashcards
what is a cell
smallest unit of life; building block of living organisms
S&F: Nucleus
structure; surrounded by nuclear envelope
function; sotrese chromosomes aka DNA and proteins; pores regulate the entry of materials
S&F; Nucleolus
Function; Assembles rRNA
Structure; inside on nucleus
S&F; Rough ER
S; studded with ribosomes
F; protein synthesis
S&F; Smooth ER
S; smooth (looks like seaweed)
F; produces lipids, breaks down toxins and stores byproducts
S&F; Golgi Body
S; stacked flattened membrane
F; receives products from the smooth ER (cis) and packages in prep. for transport, excretion or lysosomes (trans)
S&F; Plasma Membrane
S; semi-permeable bi-layer
F; regulates what comes in and out the cell
S&F; Ribosomes
S; little dots in cytoplasm/ rough ER
F; protein synthesis/ in cytoplasm they translate genetic material
S&F; Mitochondria
S; oval with cristae zig-zag, 2 membranes and circular DNA
F; cellular respiration/ cellular energy
S&F; Chloroplast
S; disk, 2 membranes, circular dna
F; turns light energy to chemical energy (photosynthesis)
S&F; Cell Wall
S; literally a wall surrounding the plat cell
F; provides strength and integrity
S&F; Cytoskeleton
S; protein filaments; microtubules, microfilaments and intermediate filaments
F; structure and movement, meiosis and mitosis
S&F; lysosome
S; little bowls
f; digestive vesicles; hydrolytic enzymes
S&F; Vacuole
S; large circle
F in animal cells; store and expel waste
F in Plant cells; stores waste and beneficial molecules
S&F; Plasmodesmata
S; pores in cell wall
F: exchange of material, cytoplasm and information between adjacent cells
