1

Ribosomes

Sites of protein synthesis

2

Microfilaments

Part of the cytoskeleton that is made of actin

3

Nucleoid

The region where DNA is found in prokaryotic cells

4

Middle lamella

The area between plant cell walls that "glues" the cells together

5

Scanning Electron Microscope

A type of electron microscope that looks that the external structures of the cell

6

Lysosomes

Digestive centers of the cell; sacks of enzymes

7

Integrins

Proteins that go all the way through the membrane; they communicate between the ECM and the cytoskeleton

8

Nucleus

Control center of eukaryotic cells

9

Cellular Respiration

Process that breaks down chemical energy (food) into ATP. This occurs in mitochondria in eukaryotic cells.

10

Cis face

Receiving side of the Golgi apparatus

11

Chromosomes

The form that DNA is in right before cell division. these are found in the nucleus

12

Prokaryote

The earliest and simplest type of cell; lacks membrane bound organelles and a nucleus

13

ECM

The structure that is on the outside of animal cells; it helps with structure and is made mostly of glycoproteins

14

Dynein Arms

Motor molecules that help move microtubules in cilia and flagella

15

Desmosomes

Anchoring junctions, these structures hold animal cells together in strong sheets

16

Photosynthesis

Process that turns light energy into chemical energy in autotrophs. It takes place in chloroplasts

17

ER

This organelle makes membranes and also helps to move substances around in the cell.

18

Eukaryotes

More highly specialized cells: they have a nucleus and membrane bound organelles; plant and animal cells are examples of this

19

Nucleolus

Structure in the nucleus that produces RNA (which eventually makes ribosomes)

20

Mitochondria

Powerhouse of the cell
Site of cellular respiration

21

Secondary Cell Wall

This is found under the primary cell wall to strengthen it; it is very strong and wood is an example of it

22

Cytoskeleton

Structural support in cells

23

Contractile Vacuole

A structure in animal cells that gets rid of excess water to prevent the cells from bursting in hypotonic solutions

24

Primary cell wall

The thin and flexible cell wall that is pliable until the plant stops growing. Once it stops growing, it hardens.

25

Cytoplasm

Everything between the nucleus and plasma membrane in eukaryotic cells; made up of cytosol and organelles.

26

Transfer Electron Microscope

A type of electron microscope that looks at the internal structures of the cells

27

Chromatin

The form that DNA is in for most of the cell cycle; long, thin strands

28

Trans face

The shipping side of the Golgi

29

Peroxisomes

Organelles that break down hydrogen peroxide into water and oxygen; this helps cells in the liver detoxify drugs and alcohol

30

Plasmodesmata

Channels through plant cell walls that allow substances to pass from one plant cell to another; similar to gap junctions in animal cells
