Adaptation of plants:
Plants adapt to their environments in various ways to survive and thrive. For example,
| Plant | Habitat | Type of Root | Characteristics of Leaves | Characteristics of Stem |
|---|---|---|---|---|
| Lotus | Aquatic | Fibrous | Large and round with a waxy layer | Hollow and flexible |
| Cactus | Desert | Taproot | Spines (modified leaves) to reduce water loss | Thick and fleshy to store water |
| Banyan | Terrestrial | Prop roots | Broad with a large surface area | Thick and woody |
