Organelles and their structure
where DNA is replicated & transcribed to form mRNA
nucleus
synthesises proteins for secretion from the cell.
Rough ER
synthesises lipids, phospholipids and steroids. special sERs stores calcium ions.
Smooth ER
processes proteins brought in vesicles to the plasma membrane for secretion
golgi apparatus
contain digestive enzymes, which can be used to break down digested food in vesicles.
can also break down organelles or whole cells.
lysosome
produce ATP by aerobic respiration. fat is digested here (if used as a energy source in cell)
mitochondria
synthesise proteins, release them to work in cytoplasm, as enzymes or else.
ribosome
produce glucose and a variety of other organic compounds by photosynthesis. sometimes contain starch grains.
chloroplast
(in some animals:) foods are digested inside vacuoles. (unicellular organisms:) expel excess water
vacuoles
form an anchor point for microtubules during cell division and also for microtubules inside cilia and flagella.
centrioles
project from cell surface, used for locomotion, also used to create a current in the fluid of the cell.
cilia & flagella
