10421301854Eukaryotic cells (eykaryotes)Cells containing a nucleus and other membrane bound organelles. All cell types other than bacteria.0
10421301855Prokaryotic Cells- cells lack a nucleus and all other membrane based organelles. Ex: bacteria1
10421301856NucleusA part of the cell containing DNA and RNA.2
10421301857NucleolusFound inside the nucleus and produces ribosomes3
10421301858Smooth ERIs ER that does not have ribosomes attached. It is a major site of lipid synthesis.4
10421301859Rough ERThat portion of the endoplasmic reticulum studded with ribosomes. Makes proteins5
10421301860Golgi bodyorganelles that package cellular materials and transport them within the cell or out of the cell6
10421301861RibosomesSite of protein synthesis. May be bound to the Rough ER or free in the cell.7
10421301862LysosomesAn organelle containing digestive enzymes used to break down food and worn out cell parts8
10421301863vacuoleCell organelle that stores materials such as water, salts, proteins, and carbohydrates9
10421301864ChloroplastAn organelle found in plant and algae cells where photosynthesis occurs, contains its own DNA10
10421301865mitochondriaEnclosed by two membranes with the inner membrane folded; contains its own DNA Site of ATP synthesis via Cellular Respiration11
10421301866Endosymbiotic theoryA theorized process in which early eukaryotic cells were formed from simpler prokaryotes by engufing them. It is hypothesized that the mitochondria and chloroplast were initially free- living bacterial cells that were engulfed by a larger, eukaryotic cell.12
10421301867Evidence for the endosymbiotic theoryChloroplast and bacteria each have a double Membrane, Same size as bacteria, contain own DNA, Divide and reproduce on their own13
10421301868Endomembrane system- definitionSystem of organelles connected by their similar phospholipid bilayers regulates protein traffic and performs metabolic functions in the cell. Builds & modifies proteins, packages them into vesicles, and sends them in the cell where they need to go (in a vesicle, bound in the membrane, exports out of the cell)14
10421301869Endomembrane system- pathwayRibosome bound to Rough ER (builds protien), Rough ER (modifies protein), Golgi (packages protein), vesicle containing protein either 1) remains in vesicle, 2) merges with the membrane to build more membrane, or 3) exports the contents outside the cell15
10421301870centriolesCell organelle that aids in cell division in animal cells only16
10421301871Surface area to volume ratioa variable that decreases as cells grow, so that it sets a limit to the size of cells.17
10421301872What kind of SA:Vol ratio is preferable to a cell? What are some ways this is accomplished?Cells require a large SA:Vol Ratio. Keeping cells small, cells with fingerlike projections increase SA.18
10421301873CytoskeletonA network of long protein strands in the cytosol that helps support the cell. Acts as "tracks" on which things can move around the cell.19
10421301874Cell WallA rigid layer of nonliving material that surrounds the cells of plants and some other organisms.20
10421301875What organelles are specific to a plant cell?Cell Wall, Large central Vacuole, chloroplast21
10421301876Cell Membranethe semipermeable membrane surrounding the cytoplasm of a cell, regulates what can enter and exit the cell.22

Need Notes?

While we strive to provide the most comprehensive notes for as many high school textbooks as possible, there are certainly going to be some that we miss. Drop us a note and let us know which textbooks you need. Be sure to include which edition of the textbook you are using! If we see enough demand, we'll do whatever we can to get those notes up on the site for you!
