Front 27

Periodic Table

Back 27

A table of all the elements

Front 28

Chemical Symbol

Back 28

One or two letters that represent an element

the number of protons an atom contains.

Front 30

Period

Back 30

A row across the periodic table

Front 31

Group or family

Back 31

Front 32

Cell Membrane

Back 32

Semi-Permeable layer that holds the cell together. Controls the flow of material in and out of the cell.

Front 33

Cell Wall

Back 33

Found in plant cells not animal cells. It's a tough and rigid (firm) outer layer that protects the cell and gives it shape.

Front 34

Cytoplasm

Back 34

Jelly like substance in the cell where all the organelles are. The cytoskeleton is located here and it helps maintain cell structure and helps things move around the cell.

Front 35

Ribosomes

Back 35

Protein making factories in the cells

Front 36

Nucleus

Back 36

Control center of the cell. Houses the cells chromosomes (which hold DNA).

Front 37

Vacoules

Back 37

Temporary storage bubbles in the cell. They store food, water, and waste.

Front 38

Lysosome

Back 38

Breaks down food, cell waste, and foreign matter

Front 39

Mitochondria

Back 39

Cell's powerhouse. They release the energy from a cell's food.

Front 40

Endoplasmic Reticulum

Back 40

Transport facility of the cell. Processes and moves materials

Front 41

Golgi Bodies

Back 41

Package, sort, and distribute stuff from the Endoplasmic Reticulum

Front 42

Chloroplasts

Back 42

In plant cells only. Contain Chlorophyll. Change energy from the Sun into food for the plant using photosynthesis.
