Plants cannot move away from danger like animals can. They must stay in one place and protect themselves from being eaten or damaged. Plants have special external structures—parts on the outside of their bodies—that help keep them safe.

Many plants have thorns or spines, which are sharp, pointed structures that grow on stems or leaves. These sharp parts poke animals that try to eat the plant. Roses have thorns on their stems, and cacti have spines covering their bodies. When an animal gets poked, it learns to stay away.

Bark is the tough, thick covering on tree trunks and branches. Bark protects trees from insects that might burrow inside and from harsh weather like wind and cold. Think of bark like a suit of armor for a tree.

Many plants have a waxy coating on their leaves. This thin layer of wax keeps water from escaping, which helps plants survive in dry places. The waxy coating makes leaves feel smooth and shiny.

Some plants have other defenses too. Stinging nettles have tiny hairs that inject painful chemicals when touched. Other plants produce bitter-tasting chemicals that make their leaves taste bad to animals. These structures and chemicals work together as the plant's defense system.

Interesting Fact: The Venus flytrap not only protects itself but also traps and eats insects! Its leaves snap shut in less than one second when an insect touches special trigger hairs inside.

What are external structures on plants?

Parts inside the plant's bodyParts on the outside of plantsParts that help plants moveParts that make plants grow taller

How do thorns protect a plant?

They make the plant taste badThey keep water inside the plantThey poke animals that try eating itThey protect from cold weather

What does bark do for trees?

Helps trees make food from sunlightProtects from insects and harsh weatherStores water for the treeHelps trees grow new leaves

Why do plants have waxy coatings?

To keep animals from eating themTo help them grow fasterTo prevent water from escapingTo protect from insects

How do bitter chemicals help plants?

They make leaves taste bad to animalsThey help plants make more foodThey protect plants from cold weatherThey help plants store water

A cactus in the desert uses spines to keep animals away and waxy coating to keep water inside. Why does it need both?

To look pretty in the desertTo survive being eaten and drying outTo grow taller than other plantsTo make seeds for new cacti
