Key Topics to Revise
1
Nervous System in Animals
- Neurons are the basic units of the nervous system, consisting of dendrites, cell body, axon, and nerve endings
- Information travels as electrical impulses through neurons via synapses
- Receptors detect stimuli from the environment (gustatory for taste, olfactory for smell, photoreceptors for light)
2
Control and Coordination in Plants
- Plants lack nervous system but show two types of movements: growth-dependent and growth-independent
- Tropic movements are directional growth responses to stimuli (phototropism, geotropism, hydrotropism, chemotropism)
- Phototropism: shoots bend towards light, roots bend away from light
3
Plant Hormones
- Plant hormones are chemical messengers that coordinate growth and development
- Auxins: promote cell elongation, cause phototropism, synthesized at shoot tips
- Gibberellins: promote stem growth and germination
4
Hormonal Control in Animals
- Endocrine glands secrete hormones directly into blood for chemical coordination
- Major endocrine glands: pituitary, thyroid, pancreas, adrenals, testes, ovaries
- Adrenaline prepares body for emergency situations (fight or flight response)
