Y7 Cells

Question 1

Cell Wall:

Answer 1

The second barrier around the cell and it keeps the plant cell firm.

Question 2

Magnification:

Answer 2

Is the power of how many times bigger you see something but it doesn’t actually increase in size in real life.

Question 3

Specialised Cells

Answer 3

A cell that is specialised to do something and can only do that thing.

Question 4

Resolution

Answer 4

Resolution is a solution to a problem.

Question 5

Vacuole

Answer 5

It contains liquids called cell sap.

Question 6

Diffusion

Answer 6

It is when an area of high concentration tries to spread out to places of low concentration so everywhere has an even amount of concentration.

Question 7

Nucleus

Answer 7

It controls the cell and contains the DNA-the information needed to make new cells.

Question 8

Organisms

Answer 8

It is a living thing.

Question 9

Chloroplasts

Answer 9

It is found in a plant cell and is made out of chlorophyll . It collects sunlight for the plant and helps in photosynthesis .

Question 10

Cytoplasm

Answer 10

It is where chemical reactions take place .

Question 11

Cell membrane

Answer 11

It controls what comes in and out and it is the first barrier around the cell.

Question 12

Mitochondria

Answer 12

It is where respiration happens.

Question 13

MRS GREN

Answer 13

Movement
Reproduction 
Sensitivity 
Growth 
Respiration 
Excretion
Nutrition

Question 14

Microscope

Answer 14

It is used to see microscopic objects, organisms or cells through the eye piece lens.

Question 15

Slide

Answer 15

It is where you put the cell to be seen under the microscope.

Question 16

Cell

Answer 16

It is what it is what all living things are made out of.

Question 17

Unicellular Organisms

Answer 17

They are cell that are organisms only using a single cell.

Question 18

Multicellular

Answer 18

Are cells that aren’t organisms by themselves but are organisms together.

Question 19

Specimen

Answer 19

Something that needs to be viewed under the microscope.

Question 20

Nerve Cell Adaptations

Answer 20

They carry electric impulses around the body. They are long and thin and has lot of connections and this helps it transmit messages around the body .

Question 21

Egg Cell Adaptations

Answer 21

It has a jelly layer to attract sperm cells. It a nucleus and cytoplasm with fat stores.

Question 22

Sperm Cell Adaptations

Answer 22

It has a streamlined head and a tail and a nucleus in the head to help it swim to the egg cell

Question 23

Root Hair Cell Adaptations

Answer 23

It absorbs water and nutrients from the soil. These cells have no chloroplasts because it is underground and it does not need photosynthesis unlike plant cells.

Question 24

Red Blood Cell adaptations

Answer 24

It transports oxygen around the body and contains haemoglobin to join to oxygen it does not have a nucleus so it can contain oxygen . And they have a disc-like surface to also increase area for carrying oxygen .

Question 25

Rate of diffusion

Answer 25

The rate of diffusion is faster when there is a more higher concentration of particles in that area ,so it tries to get to an area of lower concentration more quickly.

Question 26

Binary Fission

Answer 26

It is how cells unicellular make more cell. Using the DNA of a cell it creates another identical self of itself .

Question 27

Magnification:

Answer 27

Is the power of how many times bigger you see something .

Question 28

Specialised Cells

Answer 28

A cell that is specialised to do something.

Question 29

What is the structural pyramid?

Answer 29

Organisms
Organ systems
Organ
Tissue
Cell
