Classification and Cells
Taxis
What term describes movement in response to stimulus?
Protein
What type of molecule are enzymes?
Scurvy
What can happen if you have vitamin C deficiency?
Plasma
What is the liquid part of blood?
Maintaining a constant internal environment
What is homeostasis?
5
How many kingdoms are in the five‑kingdom system?
Complementary
What term describes enzyme‑substrate fit?
Active transport in the RHC
Which process do plants use to absorb water?
Aorta
What vessel carries blood from the heart to the body?
Speeds up nerve impulse conduction.
What is the function of the myelin sheath?
Chlorophyll makes this structure green.
What organelle contains chlorophyll?
Denaturation
What happens to enzymes at high temperature?
Translocation
What process moves sugars around the plant?
Valve
What structure ensures there is no backflow of blood?
Insulin and glucagon cause these separate mechanisms to regulate blood glucose via negative feedback.
Why does insulin lower high blood glucose and glucagon raises low blood glucose?
Plasmid
What is the structure in bacteria carrying genetic information?
What is the function of trypsin?
To digest starch
What is the role of anylase?
Translocation
What process moves sugars around the plant?
It enables a faster response to harmful stimuli by reducing neural delay.
Why do reflex arcs bypass the brain?
Chitin
What molecule are fungal cell walls made of?
It 'unzips' DNA.
DNA Helicase
To make chlorophyll
Why do plants require magnesium for photosynthesis?
Superior vena cava
What vein carries deoxygenated blood from the upper body back to the heart's right atrium?
It rotates seedlings so gravity stimulus is uniform, preventing directional growth.
How does a clinostat control for gravity when studying tropism in seedlings?
