essential parts of an animal cell

Cell membrane

• aka plasma membrane

• Regulates inflow and outflow of cytoplasmic substances

Nucleus

• contains genetic materials / DNA in chromosomes, RNA in nucleolus, nuckear sap and nuclear envelope

Mitochondrion

• boat / sausage shaped

• Regarded as the powerhouse of cell for it produces energy in the form of ATP thru kreb’s cycle/citric/tricarboxylic acid cycle

Lysosome and Peroxisomes

Contains hydrolytic and oxidative enzymes, respectively for destroying foreign agents (esp in phagocytic cells/cells capable of engulfing bacteria and viruses)

RER / granular ER

for protein synthesis

SER / agranular ER

for lipid, steroid, and carbohydrate synthesis

Ribosomes

Freely suspende in cytoplasm. Protein synthesis for internal use (lipoproteins, glycoproteins, etc.)

Golgi apparatus

• aka golgi complex / golgi body

• Packages secretory products of RER and SER prior to release out of cell

Centriole

Paired organelle (located in centrosome) which migrate to opposite poles during mitosis and meiosis and served to organize and guide the mitotic spindle during cell division process
