conditions such as pH can be maintained at an ideal level for a particular process

Organelles with their contents can be moved around within cell

Nucleus, contains the chromosomes, consisting of DNA associated with histone proteins

rER, synthesize protein for secretion from cell

golgi apparatus, processes proteins brought in vesicles brought from rER

Lysosome, contain digestive enzyme used to breakdown ingested food in vesicles or break down organelles or even the whole cell

Mitochondrion, produce ATP for cell by aerobic respiration

free ribosome, synthesize protein

chloroplast, produce glucose and other organic compounds by photosynthesis

vacuoles and vesicles, used to store vesicle and transport materials inside cell

Microtubules and centrioles, moving chromosomes during cell division

cilia and flagella, locomotion of cell
