Brain of the cell Nucleic acids are produced here (DNA and RNA) Nuclear envelope- membrane surrounding the nucleus with pores that allow certain molecules to pass through Nucleoplasm- chromatin found here (DNA and protein)

Dark spots in the nucleus Produces ribosomes

Processes, packages, and ships molecules Stacks of membranes filled with fluid Works like a factory production line

Endoplasmic Reticulum

System of folded sacs and tunnels running throughout the cell Rough ER – covered with ribosomes that make proteins for outside of the cell – looks rough because of the ribosomes on the surface Smooth ER – no ribosomes

Most numerous part of the cell. Not a membrane bound organelle because it is not surrounded by a double membrane. Where proteins for use in and out of the cell are made.

Chloroplast – green – chlorophyll absorbs sunlight – photosynthesis takes place here Chloroplast has own DNA like mitochondria Chromoplast – absorb wavelengths of light that chloroplast doesn’t

Separates the cell from the external environment. Gives shape and flexibility to the cell. Selectively permeable – allows some molecules but not all to cross the membrane

Surrounds the cell membrane Support and protection of the cell Very rigid

Fluid filled cavities Take up to 90% of the cell's volume Can store salts, toxins, water and other materials

Cleaners of the cell, prevent bad material from hurting the cell

long whip-like structure protruding from the cell (usually numbering from 1-3)

short hair-like structures protruding in large numbers from the surface of the cell

Respiration center of the cell The powerhouse Scattered throughout the cytoplasm of the cell

Jelly like material found inside the cell membrane. In constant movement – cytoplasmic streaming – carrying molecules around the cell. Acts as a shock absorber.

When two things combine, happens with bacteria. Can gain unique ability.

“Little organs”- like the organs in our body, each perform a specific function

Cell Flashcards, Biology study set for TVMSC

Term	Definition
Nucleus	Brain of the cell Nucleic acids are produced here (DNA and RNA) Nuclear envelope- membrane surrounding the nucleus with pores that allow certain molecules to pass through Nucleoplasm- chromatin found here (DNA and protein)
Nucleolus	Dark spots in the nucleus Produces ribosomes
Golgi Apparatus	Processes, packages, and ships molecules Stacks of membranes filled with fluid Works like a factory production line
Endoplasmic Reticulum	System of folded sacs and tunnels running throughout the cell Rough ER – covered with ribosomes that make proteins for outside of the cell – looks rough because of the ribosomes on the surface Smooth ER – no ribosomes
Ribosomes	Most numerous part of the cell. Not a membrane bound organelle because it is not surrounded by a double membrane. Where proteins for use in and out of the cell are made.
Chloryplast	Chloroplast – green – chlorophyll absorbs sunlight – photosynthesis takes place here Chloroplast has own DNA like mitochondria Chromoplast – absorb wavelengths of light that chloroplast doesn’t
Cell Membrane	Separates the cell from the external environment. Gives shape and flexibility to the cell. Selectively permeable – allows some molecules but not all to cross the membrane
Cell Wall	Surrounds the cell membrane Support and protection of the cell Very rigid
Central Vacule	Fluid filled cavities Take up to 90% of the cell's volume Can store salts, toxins, water and other materials
Lysosome	Cleaners of the cell, prevent bad material from hurting the cell
Flagella	long whip-like structure protruding from the cell (usually numbering from 1-3)
Cilia/pili	short hair-like structures protruding in large numbers from the surface of the cell
Mitochondria	Respiration center of the cell The powerhouse Scattered throughout the cytoplasm of the cell
Cytoplasm	Jelly like material found inside the cell membrane. In constant movement – cytoplasmic streaming – carrying molecules around the cell. Acts as a shock absorber.
Endosymbiosis	When two things combine, happens with bacteria. Can gain unique ability.
Organelles	“Little organs”- like the organs in our body, each perform a specific function
