MRS GREN is a way to remember all the characteristics of an organism. Movement Respiration etc.

Question 19

Unicellular organisms

Answer 19

These are organisms that are made up of one cell

Question 20

Multicellular

Answer 20

This means it is made up of more than one cell

Question 21

Cell membrane

Answer 21

This is the border of the cell and, like a gate it opens and closes to let things in

Question 22

Magnification

Answer 22

Magnification is when something is magnified and moves because of the magnetic pull

Question 23

Resolution

Answer 23

Resolution is the skill to know one thing from the other

The slide is the thing you put on the specimen once it has been diluted

Question 25

Chloroplast

Answer 25

This is were photosynthesis takes place

Question 26

White blood cell

Answer 26

This is what keeps all bad things out of your body, they travel in the blood flow and they kill things using antibodies they then get a memory of that thing so if it comes back it is ready.

Question 27

Organism

Answer 27

Question 28

Trachea

Answer 28

Used as a pipe for air to travel to the lungs

Question 29

Nose/Mouth

Answer 29

Used as entrances for air into the body

Question 30

Bronchus

Answer 30

The bronchus is a slightly smaller pipe than the trachea, there are two of them and they both come off the trachea. Like a upside-down Y.

Question 31

Bronchiole

Answer 31

The bronchiole is one of many bronchioles that form a tree shape in the lung and come off the bronchus

Question 32

Alveolus

Answer 32

The alveolus or air-sac is at the end of every bronchiole and is where the blood cells exchange inhaled air for the air that will be exhaled

Question 33

Diaphragm

Answer 33

The diaphragm separates the respiratory system to the abdomen

Question 34

Lung

Answer 34

The lung is where the bronchus, bronchiole and alveolus live, it protects them while they are the mechanics of the respiratory system

Question 35

Heart

Answer 35

The heart pumps blood

Question 36

Muscle

Answer 36

The muscle moves the body part/organ. In this case the lung

Question 37

Rib

Answer 37

The ribs are the protective cages that protect the lungs and heart

Question 38

Tendon

Answer 38

A tendon is what joins the muscle to the bone

Question 39

Hierarchy of living things

Answer 39

This hierarchy of living things is a table that shows all the things that live or are needed to live .e.g. Organelles, cells, tissues,organs,organ systems, organisms, ecosystems, the biosphere

Question 40

Ligament

Answer 40

A ligament is what joins together two or more bones, like a biological rope

Question 41
