Squishling — Cells: Small Units of Life Membrane Gate

Hi!

I'm Squishling.

Welcome to Membrane Gate!

Will you help me investigate cells: small units of life?

The Grumblies have mixed up our clues.

Let's check the evidence!

Living organisms are made of cells.

Some organisms are one cell;

others contain many cells with different jobs.

What are living organisms made of?

  • A. Cells
  • B. Only empty space
  • C. Only sunlight

The answer is A: Cells

Living organisms are made of cells.

Some organisms are one cell;

others contain many cells with different jobs.

That clue helps us make sense of this place.

Most cells are too small to examine well with unaided eyes.

A microscope helps reveal details;

a large cell drawing is a model, not the actual scale.

Can an organism be one cell?

  • A. No
  • B. Only if it is a plant
  • C. Yes

The answer is C: Yes

Living organisms are made of cells.

Some organisms are one cell;

others contain many cells with different jobs.

Hmm...

how does that connect to our first clue?

Our display compares a whole plant, a magnified cell image

and a labeled drawing.

All three help explain life,

but only the plant is the whole multicellular organism.

Why use a microscope?

  • A. Cells only work inside microscopes
  • B. Many cell details are too small to see unaided
  • C. Cells exist only when magnified

The answer is B: Many cell details are too small

to see unaided

Most cells are too small to examine well with unaided eyes.

A microscope helps reveal details;

a large cell drawing is a model, not the actual scale.

Nice investigating!
