Kingdom Animalia 🐾
Animals are super interesting! Here’s what makes them special:
- 🦠 Made of many cells with complex structures (eukaryotic)
- 🚫 No cell walls – that’s why we’re squishy!
- 🍔 Can’t make their own food (heterotrophic) – they eat plants or other animals
- 🔁 Eat through internal digestion (holozoic nutrition)
- 💾 Store energy as glycogen (like animal starch) or fat
- 📏 Grow in specific patterns to become adults with defined shapes/sizes
- ⚡ Advanced animals have cool nervous systems and muscles (sensory & neuromotor mechanisms)
- 🏃 Most can move (locomotion)
- ❤️ Reproduce sexually through mating, with babies developing from embryos
Kingdom Plantae 🌿 (Quick Comparison)
- ☀️ Mostly make their own food (chlorophyll-containing)
- 🪴 Have cell walls made of cellulose
- 🔄 Show alternation of generations: switch between diploid (sporophyte) and haploid (gametophyte) life stages
- 🐜 Some exceptions: Insect-eating plants (Venus flytrap, Bladderwort) and parasites (Cuscuta)
Viruses & Friends 🦠
- 🤔 Not considered “alive” in classification because they lack cellular structure
- 💎 Exist as inert crystals outside living cells
- 🤒 Cause diseases like common cold and flu
- 📛 Not included in the five-kingdom classification system
NEET Super-Important Concepts! 💡
- Animalia must-knows: Heterotrophic, multicellular, no cell walls, holozoic nutrition, glycogen/fat storage
- Alternation of generations: Key plant feature switching between sporophyte (2n) and gametophyte (n)
- Virus exclusion reason: Non-cellular nature and inert crystalline structure outside hosts
- Heterotrophic plants: Insectivores (Venus flytrap/Bladderwort) and parasites (Cuscuta)
- Animal reproduction: Always involves copulation and embryological development
Keep exploring the animal kingdom – you’re doing great! 🌟
