What do the guard cells do?
Control active transport
Control nutrients moving into the cell
Controls the rate of transpiration (loss of water through the leaf)
What does xylem transport?
Water and minerals
Water only
Sugar
Food
Without the process of transpiration, a plant would be unable to...
Move sucrose from the leaves to the roots.
Create new proteins for the plant.
Pull up new water and mineral ions from the roots to the leaves.
Grow towards the light.
After water enters the plant, water travels from the root hair cells, through the ... to the xylem vessels
phloem
cortex
mesophyll cells
cuticle
Identify the blood vessel labelled B.
Aorta
Pulmonary artery
Pulmonary vein
Vena cava
Which one is NOT correct about Sinoatrial node?
As pacemaker
Initiate the heartbeat
Generate impulse and spread it to wall of both atrium
Delay impulse from spreading to wall of atria & ventricles simultaneously.
Which one is NOT correct about Atrioventricular node?
Spread impulse to Bundle of His, branches of Bundle of His to the apex of heart and to Purkinje fibers.
Delay the impulse from SA node for about 0.1 second
Generate impulse and spread it to wall of both atrium
Allow the ventricles to contract
The contraction of the atria is controlled by the:
SA node
AV node
Purkinje fibres
Bundle of His
What area of the heart is responsible for the delay of conduction between the atrium and ventricles?
Right bundle branch
AV node
Bundle of his
Bachmann bundle
What is the important of the delay of impulse conduction between the atrium and ventricles?
To allow the atria to relax, all blood from atria pumped into ventricles, hence atria will empty completely.
To allow the ventricles to contract, pump all blood from atria into ventricles, hence atria will empty completely.
To allow atria to contract, all blood from atria pumped into ventricles, hence atria will empty completely.
Which label is representing the left & right branches of Bundle of His?
A
C
D
E
What area of the heart is responsible for the contraction of atria and allow atria to empty completely before ventricles contract?
Right bundle branch
AV node
Bundle of his
SA node
