Educational worksheet exploring how plants protect themselves from animals.

Here’s the solution to the 5 questions based on the provided text “How Plants Defend Themselves”:

---

1. What do cacti and roses have that can hurt animals?

→ Answer: Cacti and roses have sharp spikes or thorns.

*Explanation:* The text says: “For instance, some plants, like cacti and roses, are equipped with sharp spikes or thorns.” These physical defenses deter animals from eating them by causing pain or injury.

2. Why might an animal avoid eating a plant that tastes bad?

→ Answer: An animal might avoid eating a plant that tastes bad because the bad taste acts as a deterrent — it signals danger or unpleasantness, and over time, animals learn to steer clear of it.

*Explanation:* The passage states: “Moreover, certain plants taste really bad or can make animals feel unwell. This yucky taste acts as a deterrent, and over time, animals learn to steer clear of these plants.” Animals associate bad taste with negative consequences (like sickness), so they avoid those plants in the future.

3. How do some plants hide from animals?

→ Answer: Some plants hide by blending into their surroundings or mimicking the appearance of other objects, so animals may not notice them or simply pass them by.

*Explanation:* The text explains: “By blending into their surroundings or mimicking the appearance of other objects, they can often go unnoticed, and animals may simply pass them by.” This is a form of camouflage — a passive defense strategy.

4. What happens to bugs that touch plants with sticky leaves or stems?

→ Answer: Bugs that touch plants with sticky leaves or stems get trapped in the sticky mess and can’t crawl away.

*Explanation:* The passage says: “When unsuspecting bugs land there, they get trapped in this sticky mess and can’t fly or crawl away.” This is a physical trap mechanism used by some plants (like sundews or stickyweed) to capture insects — sometimes for nutrients, but also as a defense.

5. How do some plants use ants to protect themselves?

→ Answer: Some plants use ants to protect themselves by forming partnerships with them — the ants live on the plants and act as personal bodyguards, chasing away or attacking pests that come too close.

*Explanation:* As stated in the text: “For example, certain plants form partnerships with ants. These ants live on the plants and act as their personal bodyguards, chasing away or attacking any pests that come too close.” This is a mutualistic relationship — the plant provides shelter or food, and the ants provide protection.

✔ Summary of Plant Defense Strategies Mentioned:
- Physical defenses: Thorns, spikes, sticky traps
- Chemical defenses: Bad taste, unpleasant smells
