cell theory Flashcards
what types of cells are eukaryotic
plant and animal cells
what are the 5 levels of organization of organisms
cells, tissues, organs, organisms, organ system.
what types of cells are prokaryotic
bacterial cells
what structures are found in plant cells but not animal cells
chloroplasts, cell wall, central vacuole
what structures are found in animal cells but not plant cells
centrosomes, lysosomes, centrioles
what are the 3 components of the cell theory
all cells arise from pre existing cells, a cell is the basic structural and functional unit of living organisms, all living organisms are composed of one or more cells.
this is the control center of the cell
nucleus
this is the site of protein synthesis in a cell
ribosomes
this porous structure surrounds the nucleus, keeping it intact
nuclear membrane
when newly formed proteins leave the rough Endoplasmic reticulum, they are transported to this organelle, where the proteins are sorted and packaged
Golgi apparatus
this part of the cell manufactures the ribosomal subunits
Nucleolus
this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes
lysosome
the portion of the cell that exists outside of the nucleus
cytoplasm
the part of the cell that controls what enters and leaves the cell
cell membrane
the part of the cell where chromosomes would be found
nucleus
this place where lipids are manufactured
smooth endoplasmic reticulum
this part of the cell contains strong digestive enzymes to break down proteins, carbohydrates and lipids into small molecules that can be used by the rest of the cell
lysosomes
these are the most numerous of the cell’s organelles
ribosomes
this organelle consists of two types of fibers called microfilaments and microtubules
cytoskeleton
this part contains the instructions for making proteins and other important molecules
nucleus
this is the semi-fluid portion found inside the nucleus
Nucleoplasm
this organelle puts the “ finishing touches “ on proteins before they are shipped off to their final destinations
Golgi apparatus
this large structure in a plant cell is filled with water creating turgor pressure
Vacuole
this is the site of photosynthesis in a plant cell
chloroplast
