Key Topics to Revise

1

Animals - Nervous System

  • Nervous system provides control and coordination through electrical impulses
  • Receptors detect environmental stimuli (gustatory for taste, olfactory for smell)
  • Nerve impulse pathway: Dendrite → Cell body → Axon → Synapse → Next neuron
2

Coordination in Plants

  • Plants lack nervous system but show two types of movements: growth-dependent and growth-independent
  • Touch-me-not plant shows immediate response through water movement in cells, not growth
  • Tropic movements are directional growth responses to stimuli
3

Hormones in Animals

  • Hormones are chemical messengers secreted by endocrine glands directly into blood
  • Endocrine system provides chemical coordination alongside nervous system
  • Adrenaline from adrenal glands prepares body for fight-or-flight response
