1

Barrier between external and internal environment. An area where things can go in and out

Plasma membrane

2

Keeps the DNA molecules separate from metabolic machinery of the cytoplasm. Makes it easier to organize DNA and copy it

The nucleus

3

Site of translation : made of rna and proteins

Ribosomes

4

Synthesis, storage, and shipping of molecules

Endomembrane system

5

Processes proteins and makes membrane

Rough endoplasmic reticulum

6

Makes lipids,detoxification

Smooth Endoplasmic reticulum

7

Finishes making proteins and lipids that arrive and sends them to where they need to go

Golgi body

8

Transport material from organelle and plasma membrane, then breaks down waste

Vesicles

9

Produces ATP through cellular respiration, then uses energy and turns it into a useable form

Mitochondria

10

Converts sunlight energy into ATP through photosynthesis

Chloroplast

11

Network of protein fibers within a cell that defines the shape and provides strength. Gives movement.

Cytoskeleton

12

A cytoskeleton, acts as "railroads" with movement within a cell

Microtubules

13

A cytoskeleton, comprised of the protein actin

Microfiliments

14

Microtubule organizing center, help with cell division.

Centrosome and centriole

15

Slender and flexible structure functioning in motility. Used to move things around the cell. Hair like
