the nuclear envelope consists of two separate membranes that for nuclear pores at many points of the nucleus.
the hereditary material of the cell and controls cell activities
consists of RNA and proteins and are the sites of ribosomal subunit assembly.
sites of protein synthesis
ROUGH ENDOPLASMIC RETICULUM
ER with ribosomes attached and major site of protein synthesis
SMOOTH ENDOPLASMIC RETICULUM
ER does not have ribosomes attached and is the major site of lipid synthesis
a series of closely packed membrane sacs that collect, modify, package and distribute proteins and lipids produced by the ER.
membrane-bound sacs that carry substances from Golgi apparatus to the cell membrane, where the vesicle contents are released.
LYSOSOMES & PEROXISOMES
membrane-bound sacs containing enzymes.
break down phagocytized material
break down fatty acids, amino acids and hydrogen peroxide.
major sites for the rpoduction of ATP, which cells use as an energy source; also carry out aerobic respiration (requires oxygen).
supports the cytoplasm and organelles and is involved with cell movements.
composed of microtubules, microfilaments and intermediate filaments.
locasted in the centrosome, are made of microtubules. They facilitate chromosome movement during cell division.
move substance over the surface of the cells
much longer than cilia and propel sperm cells
increases the surface area of the cells, aiding in absorption
