M2: Cell Organelles Activity Flashcards
consist of semipermeable phospolipid bilayer
cell membrane
a jelly like substancve that fills the interior space of cells
cytoplasm
controls which substances enter and leave the cell, and also seperates the interior of the cell from its externakl environment
cell membrane
it is main composed of water, but also contains salts, enzymes and other organic molecules
cytoplasm
surround and protects the organelles of the cell and is where many cellular processes (such as protein synthesis and glycolysis) take place
cytoplasm
the control center of the cell and houses all the cell’s genetic information
nucleus
protects the cell’s DNA while controlling all other cellular activities, such as cell division, growth, protein production and cell death
nucleus
site of production in plant and animal cells
ribosome
produce proteins by assembling amino acid sequences according to the instructions contained in the genetic code
ribosome
is a network of membranes inside a cell, and its main functions are to process and transport new materials
endoplasmic reticulum
endoplasmic reticulum has two types which are
rough er and smooth er
is studded with ribosomes, giving it a bumpy or “rough” appearance. it folds and tags newly synthesized proteins before transporting them to wherever they are needed in the body
rough er
does not have ribosomes attached to it and is instead involved in hormone and lipid synthesis
smooth er
a series of flatted, membrane bound sacs that packages and distributes substances to outer cell membrane, where they either become part of the lipid bilayer of leave the cell
golgi apparatus
the site of respiration and ‘powerhouses’ of cells, pumping out energy which is then stored in ATP (adenosine triphosphate). ATP molecules are the energy currency of cells and are used to fuel all the other activities of the cell
mitochondria
