cell Flashcards
mitochondria
- powerhouse/energy production for cell
- food enters the cell as glucose and this is where glucose is converted into energy to power
endoplasmic reticulum
- divides the cell into compartments
- forms surfaces where many chemical reactions occur
- two types, smooth, and rough
cell membrane
select what goes in and out
peroxisome
releases enzymes to breakdown harmful substances
vacuole
stores everything
ex, fluid, waste, food, proteins, toxins etc (grandmas attic)
lysosome
relates enzymes to digest old/worn out cells
Golgi app/complex
modify and transport proteins
microvilli
- not on all cells
- increases surface area for secretion or absorption
- short extension of the cell membrane
centrioles
-aids in cell division by pulling the chromosomes towards the opposite poles to help in the formation of two new cells
cytoplasm
fluid in cell
-found btw the nuclear membrane and cell membrane
nuclear membrane
select what goes in and out of the nucleus
nucleus
control centre
- contains all the genetic material and chromosomes
- regulates the passage of substances into the cell
nucleolus
makes ribosomes
what is the study of cells called
cytology
cell functions
- obtain or make food
- digest and assimilate nutrients
- expel waste into the environment
flagellum
- long, whip-like projection from the cell
- moves the cell
- in humans, the only cell with a flagellum is a sperm cell
microtubules
-play an important role in lining up duplicated chromosomes and movement of chromosomes to opposite poles of a cell undergoing cell division (mitosis)
rough end. reticulum
- gives a large surface area for ribosomes to attach to the cytoplasmic surface of the ER
- bumpy appearance
- allows for transportation of proteins into the ER
smooth end. reticulum
-area of the ER without attachment of ribosomes
ribosomes
makes protein
cilia
hair like projections to filter
vesicle
stores materials to transport
chromatin
