Cell Adaptations

What is one possible reason for seeds to have hooks or barbs?

• to stay warm during the winter

• to protect themselves from sunlight

• to get attached to passing animals and get carried away

• to stick to animals and steal nutrients from them

What adaptations do roots have that help them absorb water and minerals?

• They have a high surface area and lots of mitochondria

• They are covered in water attracting chemicals

• They have a low surface area with very few mitochondria

• They have no chloroplasts

Cactus have a thick waxy coating on their stem that keeps them from drying out- is this a behavioral adaptation or physical adaptation?

• Behavioral adaptation

• Physical adaptation 

A nice smell is an adaptation that__________.

• helps the plant keep water inside the leaves

• pokes animals that try to eat the plant

• attracts pollinators to the plant.

How do red blood cells adapt to efficiently transport oxygen?

• They have a biconcave shape to increase surface area

• They have a spherical shape to store more oxygen
