22
Q

What are the 4 organs of a flower?

A

Root, leaves, stem and petals/flower

23
Q

Why are unicellular organisms constantly in direct contact with their environment?

A

So they can absorb nutrients straight from their surroundings, which is why they do not need organ systems

24
Q

Why do multicellular organisms need organ systems?

A

They have many more cells that cannot all be in direct contact with the environment, therefore the organisms develop systems to ensure they receive all nutrients that they need, which is why we need organ systems.
