Term
Cell Theory
Definition

→ all living things are composed of one or more cells,

→ cells are the basic untis of structure & function

→ new cells are product of fresh* existing cells.

 

* couldn't read that word, i wrote it lol. so guessed.

Term
Ribosemes
Definition

site of protein synthesis

can be found attached to Rough ER or free cytoplasim

 

 

[image][image]

 

Term
Endoplastic Reticulum (ER)
Definition

site of chemical reactions; highways of cells;

Rough ER:

studded with ribosomes; productions & transfer of protiens

 

Smooth ER:

No ribosomes; production of storage of lipids

[image][image]

 

Term
Golgi Apporatus
Definition

stores modifies & packages protiens

molecules transported to & from the Goli by vesicles

looks like a stack of protiens

 

[image][image]

Term
Lysosomes
Definition

Contains digestive enzymes

→ "garbage disposal"

breaaks down watse

→ worn out organelles foood particles bacteria, ect.

[image]

 

Term
Vaculoe
Definition

Sorage container for water, food & more.

→ large central vacuole in plant cells

→ many smaller vacuoles in animal cells

 

Membrane-bound spaces (sacs)

Term
Mitochondria
Definition

Celluar respiration occurs here to realse energy for cell to use

→ "power houes" of the cell.

 

has an outer membrane & a high folded inner membrane

[image][image]

 

Term
Choroplast
Definition

Site of food (glucose) production

→contains the greeen pigment, chlorophyl

 

not found in animal cells.
