🧬 NEET Biology Class 11 Notes Important Topics
Chapter 1 – The Living World
Biology is the science of life. Organisms show growth, reproduction, metabolism, and response to stimuli.
- Metabolism: Sum of all biochemical reactions in a living cell.
- Taxonomy: Science of naming and classifying organisms.
- Binomial Nomenclature: Proposed by Linnaeus — two names (Genus + Species).
- Hierarchy: Kingdom → Phylum → Class → Order → Family → Genus → Species.
- Taxonomical Aids: Herbarium, Botanical Gardens, Museums, Zoological Parks.
Chapter 2 – Biological Classification
- Whittaker’s Five Kingdoms: Monera, Protista, Fungi, Plantae, Animalia.
- Monera: Prokaryotic (bacteria, cyanobacteria).
- Protista: Unicellular eukaryotes (Amoeba, Euglena).
- Fungi: Heterotrophic, chitin wall, spore reproduction (Yeast, Mushroom).
- Plantae: Multicellular autotrophs with cellulose walls.
- Animalia: Multicellular, no cell wall, heterotrophic.
Chapter 3 – Plant Kingdom
- Major Groups: Algae, Bryophyta, Pteridophyta, Gymnosperms, Angiosperms.
- Algae: Aquatic, photosynthetic (Chlamydomonas, Spirogyra).
- Bryophytes: Require water for fertilization (Mosses).
- Pteridophytes: First vascular plants (Ferns).
- Gymnosperms: Naked seeds (Cycas, Pinus).
- Angiosperms: Flowering plants with double fertilization.
Chapter 4 – Animal Kingdom
- Organisation Levels: Cellular → Tissue → Organ → System.
- Symmetry: Radial (Hydra), Bilateral (Human).
- Phyla Highlights: Porifera, Cnidaria, Platyhelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Chordata.
Chapter 5 – Morphology of Flowering Plants
- Root: Tap vs Fibrous types and modifications (carrot, beetroot).
- Stem: Support and transport (potato = modified stem).
- Leaf: Photosynthesis and gas exchange (onion = modified leaf).
- Flower: Reproductive structure (Calyx, Corolla, Androecium, Gynoecium).
- Fruit & Seed: Ripened ovary and fertilized ovule.
Chapter 6 – Anatomy of Flowering Plants
- Tissues: Meristematic (Apical, Intercalary, Lateral) and Permanent.
- Xylem: Transports water and minerals.
- Phloem: Transports food throughout plant.
- Secondary Growth: Vascular cambium activity forms annual rings.
Chapter 7 – Structural Organisation in Animals
- Tissues: Epithelial, Connective, Muscular, Nervous.
- Examples: Bone, Cartilage, Ligament, Neuron.
- Animals to Study: Earthworm, Cockroach, Frog.
