10

Atom

The building block of matter

11

Molecule

a group of atoms bonded together

12

organelle

a small body in the cell's cytoplasm that preforms a specific function in the cell

13

Cell

The basic unit that can preform all life processes; made of cytoplasm and organelles inside a membrane

14

Tissue

group of similar cells that preform a common function

15

Organ

a collection of tissues that carry out a specialized function of the body

16

Organ System

a group of organs that work together to preform body functions

17

Organism

a living thing; anything that can carry out life processes independently

18

Cell Wall

A rigid structure surrounding the cell membrane that provides support. Only found in plant cells

19

Cell Membrane

Protects the cell; controls the movement of materials into and out of the cell. Found in both Animals and plant cells

20

Cytoplasm

The fluid that all the cell's organelles outside the nucleus; the site of most cell activities. Found in both Animals and plant cells

21

Nucleus

contains the cell's DNA, the instructions that direct all cell activities. Found in both Animals and plant cells

22

Ribosomes

make proteins. Found in both Animals and plant cells

23

Endoplasmic Reticulum

'rough' ER processes and transports proteins that are made by ribosomes covering it
'smooth' ER make lipids
Found in both Animals and plant cells

24

Mitochondria

a chemical reaction called cellular respiration occurs here, breaking down sugar to release energy. Found in both Animals and plant cells

25

chloroplasts

a chemical reaction called photosynthesis occurs here and stores energy (in the form of sugar) only found in plant cells

Golgi complex

Packages and distributes lipids and proteins. Found in both Animals and plant cells

27

Lysosomes

Digest large molecules and other waste. only found in animal cells

28

Vacuoles

large round sacs that store water and other materials. Found in both Animals and plant cells

29

eye piece

contains ocular lense

30

nose piece

allows you to change between objective lenses

31

objective lenses

each one has a different magnification factor

32

arm

Holds up the part that you look through and gives easy access to transportation

33

stage

the surface on which you place the sample

34

Stage clips

Secure the sample in place so it doesn't move round

35

Diaphragm

allows you to adjust the amount of light that comes through the stage

36

light source

when turned on helps you view the sample

37

base

Helps stabilize and support the whole microscope
