Cell Wall

 

[image]

Definition

Plant,mushroom,bacteria & protist cells. Prodvides shape and support, Found outside of cell/plasma membrance

 

 

Term

Cell/plasma membrane

 

[image]

Definition

-membrance that surronds the cell. Allow some molecules to pass through its, others not. holds in cell parts. found in all cells

 

 

Term

Cytoplasm

 

[image]

Definition

-jelly-line substance in the cell -holds nucteus & organelles -found in all cells

 

 

Term

Mitchordria

 

[image]

Definition

-where celluar respiration takes places -converts food into energy -powerhouse of the cell -plant and animal cell

 

 

Term

Chloroplast

 

[image]

Definition

Converts light into energy. Found in Protist & plants. Give plants its green color

 

 

Term

Ribosome

 

[image]

 

 

Definition

are the protein builders or the protein synthesizers of the cell.

 

 

Term

Vocuoles

 

[image]

Definition

Storage sac for food and water. Found in plant and animal cells Huge main are in plant cells

 

 

Term

lysosomes

 

[image]

Definition

is basically a specialized vesicle that holds a variety of enzymes. They might be used to digest food or break down the cell when it dies

 

 

Term

Golgi Bodies

 

[image]

Definition

flattered membrance used for synthesizing(te make) packaging and distribution found in plant and animal cells

 

 

Term

Endoplasmic Reticulum (er)

 

[image]

Definition

Where parts of the cell membrane are made. Where proteins are chemically modified. Produces litids rids cell of toxins transport system found in Animal,Plant cells

 

 

Term

Cytoskeleton

 

[image]

Definition

help move internal cell parts- support for cell found in animal cells

 

 

Term

Centrioles

 

[image]

Definition

found in animsls cells only Special cytosk eleton needed for cell reporstion full art

 

 

Term

Nucleus

 

[image]

Definition

-Control center of the cell -has hereditary information -has double membrane with small holes - found in plant and animal cells

 

Term

Cilia

 

[image]

Definition

-only in animal and bacteria cells -short,hair-like extension on surfaceof cell -used for movement and gathering food

 

 

Term

Flagella

 

[image]

Definition
-only in Animal and bacteria cells -long, whip-like extensions of the surface of cells -used for movement
Term

Prokaryotic

 

[image]

Definition

-Does not have true nucleus -Has genetic material -Has no membrane bound organellas Bacteria are prokaryotes.

 

 

Term

Eukaryotic

 

[image]

Definition

-Has a nucleus -Has membrane bound organelles -Tend to be larger than prokaryotic cells
