Biological Science Revision Checklist
Everything to revise for BSE Telangana Class 10 Biological Science — diagrams, life processes, control and coordination, reproduction, and ecology by exam priority.
Diagrams — High Priority
High- Nephron: glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal tubule, collecting duct
- Neuron: cell body, dendrites, axon, myelin sheath, nodes of Ranvier, axon terminal
- Human heart: four chambers, valves, major blood vessels (aorta, pulmonary artery, vena cava)
- Cross-section of leaf: epidermis, mesophyll cells, stomata, guard cells, xylem, phloem
- Reflex arc: receptor → sensory neuron → spinal cord → motor neuron → effector (muscle)
Life Processes — High Priority
High- Nutrition: autotrophic (photosynthesis equation + conditions) vs heterotrophic (types)
- Respiration: aerobic (mitochondria, 36 ATP) vs anaerobic (cytoplasm, lactic acid/ethanol)
- Transportation: double circulation in humans — pulmonary and systemic loops
- Excretion: kidney function — filtration, reabsorption, secretion, urine formation
- Translocation in plants: phloem, source-to-sink movement; transpiration through stomata
Control and Coordination — High Priority
High- Nervous system: central (brain + spinal cord) vs peripheral; voluntary vs reflex actions
- Brain: cerebrum (thinking), cerebellum (balance), medulla oblongata (involuntary actions)
- Endocrine glands and hormones: pituitary (GH), thyroid (thyroxine), adrenal (adrenaline), pancreas (insulin)
- Plant hormones: auxin (phototropism), gibberellins (growth), abscisic acid (dormancy)
- Synapse: neurotransmitters bridge gap — impulse crosses chemically, not electrically
Reproduction and Heredity — Medium Priority
Medium- Asexual reproduction: binary fission, budding, fragmentation, spore formation — one example each
- Sexual reproduction in plants: pollination types, fertilisation, seed and fruit formation
- Human reproduction: menstrual cycle, fertilisation, implantation, gestation
- Mendel's Laws: Law of Dominance, Law of Segregation — monohybrid cross 3:1 ratio
- Sex determination: XX = female, XY = male — father determines sex, not mother
Ecology — Medium Priority
Medium- Ecosystem components: producers, consumers, decomposers — examples from grassland and aquatic
- Food chain: grass → grasshopper → frog → snake → eagle — energy flows, matter recycles
- Ozone depletion: CFCs → ozone destroyed → UV reaches Earth → skin cancer, plant damage
- Biodiversity threats: habitat loss, poaching, pollution, invasive species
- Conservation methods: in-situ (national parks) and ex-situ (zoos, seed banks)
