Cell Parts And Functions Flashcards
Two types of animal cells
Somatic and gamete cells
Prokaryotes have…and instead have…
No nucleus, nucleoid
Eukaryotic cells…
have a nucleus
DNA is in chromatin network form during…
Quiescence/resting phase
Another word for cell membrane
plasmalemma
What is the main part of the cell membrane?
The phospholipid bilayer
Carrier proteins…
Change shape for large/ bulk movement of proteins
Channel proteins
Have a fixed shape, for medium substances
Both channel and carrier proteins are for
Larger substances that can’t fit through the phospholipid bilayer
Diffusion
Movement of substances from high to low concentrations
For active transport the mitochondria…
Produce energy and shock the particle into moving through the cell wall
Cytosis uses what to move bulk substances?
It uses ATP
Endocytosis
Bulk movement of substances into the cell
Exocytosis
Bulk movement of substances out of the cell
Mitochondria
Makes ATP
Golgi body
Collects substances and transports them to where they are needed
Endoplasmic reticulum with ribosomes
Protein synthesis
Smooth endoplasmic reticulum
Carbohydrate and lipid synthesis
Peroxisome and lysosome
Remove waste from the cell using the acid inside them
Ribosome
Protein synthesis
Centrosome
Form spindle fibre for mitosis
Nucleus
Contains DNA and controls cell activities
Cytoplasm
Holds the organelles in place, provides mechanical support for the cell
