Living Things Meet Their Needs - Unit Review

​Understanding the Biosphere

What does it mean to be Living?

Review - Organisms

​

• Organisms are living things.

• Organisms have a life cycle:

  • Be Born, Grow, Reproduce, Die

• Organisms have needs:

  • Food, Water, Shelter, Air

• If an organism cannot meet it's needs, it will die.

• ​Organisms are made of parts that work together to help the organism meet it's needs.

• Each part does a different job.

• The science word for job is Function. ​

Organisms are made of cells.

​

• Organisms are made of cells.

• The cells are too small to see. We need a microscope.

• Not all cells look the same.

• Cells will have different shapes, sizes, and parts depending on their function. ​

Multiple Choice

How can we see cells?

• With a telescope

• With a microscope

Multiple Choice

Why do we need a microscope to see cells?

• They are too small to see with our eyes.

• They are too far away to see with our eyes.

• They are clear, so we would see right through them.

Multiple Choice

Are all cells exactly the same?

• Yes!

• No, they have different shapes and functions.

• No, they have the same shape but different functions.

• No, they have different functions but the same shape.

Review - Cells are made of organelles.

​

• Cells are living things, so they have needs.

• To meet their needs, cells need different parts to help them perform each function.

• The parts of a cell are called organelles.
