Cell membrane, Cytoplasm, Mitochondria, Nucleus, Ribosomes.

Front 2

Name the Parts of the plant cell?

Back 2

Nucleus, Vacuole, Mitochondria, Chloroplast, Cell Membrane, Cell Wall, Ribosomes, Cytoplasm.

Front 3

What is the Cell Membrane?

Back 3

A selectively permeable outer layer, controls what goes in and out of the Cell.

Front 4

Describe the Cytoplasm

Back 4

Mainly made of water and salts and sugars, where chemical reactions take place.

Front 5

What does the Nucleus do?

Back 5

It controls the cells activities.

Front 6

What does the Mitochondrion do?

Back 6

It's the sit of energy production (respiration)

Front 7

What's the job of the Ribosome?

Back 7

Found in the cytoplasm and is where protein synthesis takes place.

Front 8

What does the Cell Wall do?

Back 8

Strong and flexible. Made from cellulose. Gives the Cell support.

Front 9

The Vacuole does what job?

Back 9

Store what inside the Cell.

Front 10

What does the Chloroplasts do?

Back 10

Contains chlorophyll. Where photosynthesis takes place.

Front 11

What are the Parts of cells called?

Back 11

Organelles

Front 12

What is osmosis?

Back 12

The diffusion of water from an area of high concentration to low concentration across a selectively permeable membrane.

Front 13

What is a cell made up of?

Back 13

99% water, 1% sugar and salt.

Front 14

What does turgid mean?

Back 14

The Cell is full of water

Front 15

What does plasmolysed mean?

Back 15

The process of extreme water loss in a plant cell.

Front 16

What will happen to an animal cell in a pure water solution?

Back 16

They will burst and die

Front 17

What are cell membranes made out of?

Back 17

Proteins and phospholipids

Front 18

What does DNA carry the information to make?

Back 18

Protiens

Front 19

What are the bases in DNA?

Back 19

A, C, T, G

Front 20

What pairs of bases always go together?

Back 20

A+T and G+C

Front 21

What is the shape of DNA?

Back 21

Double helix

Front 22

What is mRNA?

Back 22

Messenger RNA, a copy of DNA

Front 23

What is genetic engineering?

Back 23

The transfer of DNA from one organism to another

Front 24

What are enzymes?

Back 24

Biological catalysts, made by all living cells

Front 25

What happens to enzymes during chemical reactions?

Back 25

They speed them up, are unchanged and always produce the same products.

Front 26

What is the name of the conditions that enzymes work best at?

Back 26

Optimum conditions

Front 27

What effects enzymes?

Back 27

pH and temperature

Front 28

What happens when an enzyme is denatured?

Back 28

It's shape changes, therefore its active site no longer fits with the substrate

Front 29

What is the active site of an enzyme?

Back 29

The place that binds with the substrate and reacts

Front 30

What does "enzymes are specific" mean?

Back 30

They only react with one substrate

Front 31

What is ATP?

Back 31

Adenesine Triphosphate

Front 32

What is the word equation of aerobic respiration in animals?

Back 32

Glucose + oxygen = ATP + Carbon Dioxide + Water

Front 33

Where does the first stage of aerobic respiration in animals take place?

Back 33

Cytoplasm

Front 34

Where does the second stage of aerobic respiration in animals take place?

Back 34

Mitochondria
