HSPT: self study cell structure

Plasma Membrane:

separates internal components of cell from surrounding environment, permeable membrane

Cytoplasm:

suspended organelles, chem reactions, gel-like fluid inside

Nucleus:

control center, regulates cell activity, genetic material, DNA material in center

Nuclear Membrane:

protects nucleus, only specific materials, double-layered membrane

Nucleolus

forms RNA/ribosome, body within nucleus

Mitochondria:

convert nutrients into energy, creates ATP, powerplant of cell

Ribosomes:

protein synthesis for internal/external, use small RNA in nucleus/cytoplasm

Endoplasmic Reticulum:

transports materials throughout cell, connects cell-membrane to nucleus mem.

RER + SER

synthesis/transport of proteins

synthesis + lipid molecules

Golgi Apparatus

packages/releases material secreted by cell for external use, 4-6 membrane sacs, near nucleus

Lysosomes:

digest waste material found in cell, sacs surrounded by membranes

Cytoskeleton:

maintains shape/structure of cell, keeps organelles in place

Centriole

cell reproduction through DNA to new cells, rod-shaped bodies

Cilla:

aid in movement of substances along cell surface, short hair-like microtubules

Flagella

move cell itself, long hair-like microtubules
