Plantas en hábitats extremos

The video explores how various plants adapt to extreme environments. South African aloe regulates heat by excreting salt as a white powder, reflecting sunlight. The saguaro cactus stores water in its stem, protected by spines from predators. In polar regions, Arctic plants grow close to the ground to withstand cold temperatures. The alpine poppy tracks the sun for effective pollination. These adaptations help plants manage temperature, conserve water, and capture sunlight, ensuring survival in harsh conditions.

How does the South African aloe manage to reflect sunlight?

• By shedding its leaves

• By absorbing salt and excreting it as a white powder

• By growing taller

• By having thick leaves

What is the primary function of the saguaro cactus's thick spines?

• To store water

• To attract pollinators

• To defend against predators

• To absorb sunlight

How do Arctic plants adapt to extremely low temperatures?

• By growing tall and isolated

• By having deep root systems

• By growing close to the ground and each other

• By changing color

What unique behavior does the alpine poppy exhibit to aid in pollination?

• It produces a strong scent

• It changes color throughout the day

• It grows underground

• It rotates 360º to follow the sun

What is a common adaptation among plants in extreme environments?

• Producing more seeds

• Regulating temperature, conserving water, and capturing sunlight

• Developing deep root systems

• Growing taller than other plants
