Las defensas de las plantas

Plants have developed various defense mechanisms to protect themselves from predators. These include mechanical defenses like thorns, as seen in acacia trees, and chemical defenses such as toxins in ferns. Some plants, like the mimosa, use movement to avoid threats, while others, like the white nettle, rely on mimicry to deter predators. These strategies highlight the adaptability and complexity of plant defenses.

What is the primary function of the acacia's stinging spines?

• To attract pollinators

• To deter herbivores

• To store water

• To support the plant structure

What happens when a grasshopper touches a mimosa plant?

• The plant changes color

• The plant grows faster

• The plant closes its leaves

• The plant releases a scent

Why do some acacia trees grow in the shape of an umbrella?

• To attract more insects

• To collect rainwater more efficiently

• To prevent giraffes from reaching the upper leaves

• To provide shade for other plants

How do ferns protect themselves from being eaten?

• By having tough, inedible leaves

• By using toxins as a chemical defense

• By camouflaging with their surroundings

• By growing in inaccessible areas

What is the main advantage of mimicry for the White Nettle?

• It attracts more sunlight

• It enhances seed dispersal

• It confuses pollinators

• It avoids predators without producing stingers
