Answer 1

It’s a site of chemical reactions in the cell that contains enzymes to catalyse reactions

Question 2

What is the Nucleus?

Answer 2

It contains genetic material and controls activities of the cell and codes fro proteins

Question 3

What is the cell membrane?

Answer 3

It’s a semi permeable cell that controls the movement of all substances in and out of the cell

Question 4

What is the ribsome?

Answer 4

It’s a site of protein synthesis that mRNA is translated to an amino acid chain

Question 5

What is the mitochondrion?

Answer 5

Answer 6

The plant and Animal cell

Question 7

What is the permanent vacuole?

It contains cell sap, keeps cell turgid and contains sugars and salts in solution

Question 8

What do the cell wall?

Answer 8

It’s made of cellulose and supports and strengthens the cell

Question 9

What is chloroplast?

Answer 9

It’s the site of photosynthesis, contains chlorophyll and absorbs light energy

Question 10

What is cell differentiation?

Answer 10

It’s how a cell changes and becomes specialised, undifferentiated cell and are called STEM cells

Question 11

What’s in a animal cell?

Answer 11

Cytoplasm, A nucleus, Cell membrane and mitochondria

Question 12

What’s in a plant cell?

Answer 12

Cytoplasm, A nucleus, Cell membrane, cellulose cell wall, mitochondria, permanent vacuole and chloroplast

Question 13

What is in Bacterial Cells?

Answer 13

The Cell Membrane, Bacteria DNA, Cell wall, Plasmid and Cytoplasm

Question 14

What is Bacterial DNA?

Answer 14

It controls the function of a bacterial cell and it’s not in nucleus it just floats in the cytoplasm

Question 15

What is a plasmid?

Answer 15

It’s small rings of DNA and contains additional genes

Question 16

What are bacterial cells?

Answer 16

They’re smaller than plant and animal cells and are prokaryotes simpler organisms

Question 17

What is a nerve cell?

Answer 17

It’s a long branched cell that carry electrical signals

Question 18

What is a sperm cell?

Answer 18

It’s a specialised animal cell that has a long tail and fertilises a egg in reproduction

Question 19

What is a muscle cell?

Answer 19

It’s a specialised animal cell that contains a large number of mitochondria and contracts to allow movement

Question 20

What is a root hair cell?

Answer 20

It’s a hair like projection to Ashton water and minerals from soil

Question 21

What’s a xylem?

Answer 21

It’s through transpiration and carries a water and minerals

Question 22

What is a phloem cell?

Answer 22

It’s through translocation and carries glucose

Question 23

What is the calculation for magnification?

Answer 23

Magnification = Size imagine / Real size of the object

Question 24

What is a cell?

Answer 24

It’s the smallest structural and functional unit of an organism

Question 25

What is DNA?

Answer 25

It’s a polymer made of 2 strands forming a double helix

Question 26

What is mitosis and the cell cycle?

Answer 26

Cells divide in a series of stages. The genetic material is doubled and then divided into 2 identical cells.

Question 27

What are stem cells?

Answer 27

They are undifferentiated cells of an organism which divides to form more cells of the same type and can differentiate to form many other cell types.

Question 28

What are adaptions for diffusion?

Answer 28

The greater the difference in concentrations the faster the rate of diffusion

Question 29

What is diffusion?

Answer 29

It’s the moment of particles in a solution from a higher to lower concentration

Question 30

What is osmosis?

Answer 30

It’s the movement of water from a dilute solution to a more concentrated solution

Question 31

What is active transport?

Answer 31

It’s the moment of particles from a dilute solution to a more concentrated solution with required energy
