cell organelles

Terms in this set (47)

stores material within the cell
vacuole
closely stacked, flattened sac (plants)
chloroplast
sites of protein synthesis and builds proteins
ribosomes
transports materials within the cell
vesicles
region inside the cell that secures organelles
cytoplasm
manages or controls all the cell functions in a eukaryotic cell
nucleus
digests excess or worn out cell parts, food particles and invading viruses or bacteria
lysosome
cell membrane
separates cell from outside and controls what enters and exits
plant support and gives plants their shape
cell wall
gives the cell energy -ATP
mitochondria
builds proteins in the cytoplasm
rough er
builds membrane in the cytoplasm
smooth er
finishes, sorts, packages, and ships proteins
Golgi Apparatus
protect DNA and let RNA out
nuclear membrane/envelope
genetic info and DNA
chromatin
makes ribosomes inside nucleus
nucleolus
cell movement attached to the outside of the cell
flagellum
cell movement- multiple attached to the outside of the cell
cilia
water storage (plants)
central vacuole
makes energy and sugar
chloroplast (green stacks)
cell support
microtubules
cell structure and cytoskeleton
mircofilaments
coordinate cell division
centrioles (animal)
are these cells eukaryotic or prokaryotic? explain
eukaryotic because they have a nucleus
where is DNA found (chromatin)
in the nucleus
describe the general shape of the cork cells under the microscope
squiggly circles that are all connected
what organelles were seen in the cork cells
none bc cork cells are dead
what is the shape of stained onion Epidermal cells
long rectangles and skinny
what does the Elodea egeria look like
long rectangluar bricks that area green and moving
what does the stained human cells look like
ovals with dark purple nuclei and the cytoplasm is foggy and light purple
how can u tell the cork cell is not alive
there are no organelles
what did Rober Hooke really see when he looked through the microscope
cell wall
based on lab, how are human epithelial cells and living plant cells have in common
cytoplasm, cell membrane and nucleus
based on lab, how are human epithelial cells and living plant cells differ
plant cells have a cell wall and chloroplast
some epithelial cells are folded and wrinkled what does this tell you about the thickness of the cells
they are very thin
why do Elodea cells contain chloroplasts and onion cells do not
onions grow under ground so they do not use sunlight so they do not use photosynthesis unlike Elodea
what are structures the plant cell has that the animal cell does not
cell wall, chloroplast, and central vacuole
what are structures the animal cell has that the plant cell does not
centrioles
what did Robert Hooke observe
walls of dead plant cells and named them compartments/cells
what remained after the cork cells
polysaccharides
what did Anton Von Leeuwenhoek observe
tiny living organisms in pond water and was the first to observe living organisms ("animalcules")
what is the cell theory
1. all living things are made of cells
2. cells are the basic unit of structure and function
3. all cells come from pre existing cells
what are the 2 classes of cells
eukaryotic and prokaryotic
what are the 7 features of all cells
1. structure relates to function
2. small size
3. plasma membrane
4. cytoplasm
5. DNA
6. ribosomes
7. cytoskeleton
what gives a solid shape
cytoplasm
what are the 3 jobs of cells
1. make energy
2. make proteins (do the work in the cell)
3. make more cells (for growth and replace damaged/diseased cells)
what do organelles do
do the work of the cell and have a specific job
