Organising Animals and Plants

Question 1

Ventricles?

Answer 1

Large chambers in the heart, right vent to lungs, left vent to body

Question 2

Atria

Answer 2

Small chambers of heart, fill with blood into vena cava and pulmonary vein, then pump blood into ventricles

Question 3

Aorta

Answer 3

Artery leaving the left ventricle

Question 4

Vena cava?

Answer 4

Major vein transporting blood from whole body back to heart

Question 5

Pulmonary vein

Answer 5

Vein leading from lungs to heart

Question 6

Artery

Answer 6

Blood vessel that carries blood away from heart at high pressure

Question 7

Capillary?

Answer 7

Very small, thin walled blood vessel where exchange happens

Question 8

Vein?

Answer 8

Blood vessels that return blood to the heart at low pressure

Question 9

Coronary blood vessel

Answer 9

Heart needs its own blood supply, from this

Question 10

Plasma?

Answer 10

Fluid in red blood cells with glucose, protein, ions and CO2

Question 11

Red blood cells

Answer 11

Biconcave shaped cells that contain haemoglobin which binds to oxygen making oxyhaemoglobin

Question 12

White blood cells

Answer 12

Cells that fight pathogens and release antibodies

Question 13

Platelets?

Answer 13

Fragment of cells that cause blood clotting

Question 14

Epidermal tissue?

Answer 14

Plant tissue that covers the whole surface

Question 15

Palisade mesophyll

Answer 15

Tissue in leaf where photosynthesis happens

Question 16

Spong mesophyll

Answer 16

Tissue in the leaf with air between cells, specialised for gas exchange

Question 17

Xylem

Answer 17

Narrow tubes in roots, stem, leaves which transport water and mineral upwards

Question 18

Phloem

Answer 18

Tubes that run alongside xylem, transport sugards and dissolve water, (transpiration)

Question 19

Meristem?

Answer 19

Type of tissue found at tips of roots containing stem cells so they can differentiate

Question 20

Guard cell

Answer 20

Guard cells form stomata on leaves, holes where gas is exchanged, can open and close as required

Question 21

Transpiration?

Answer 21

Process where plants lose water as vapour through stomata

Question 22

Factors affecting transpiration?

Answer 22

High temp, low humidity, high air flow, high light intensity

Question 23

Stomata

Answer 23

Holes where gas are exchanged

Question 24

What do stomata allow to enter?

Answer 24

Carbon dioxide for photosynthesis

Question 25

What controls stomata opening?

Answer 25

Guard cells
