Cell Organelles and Their Jobs

Lab Brief #6

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

Nature loves to surprise the careful watcher.

What you'll learn

Cell organelles each have specific functions. The mitochondria produce energy, the ribosome makes proteins, the endoplasmic reticulum processes molecules, and the Golgi apparatus packages them.

Key words

cell
The tiny building block that makes up all living things.

Make a hypothesis first

Before you start: write down what you think will happen, and why.

Say your guess out loud — then find out if you were right.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Build a 3D cell model using household materials (plastic bag for membrane, gelatin for cytoplasm, a grape for nucleus). Label all organelles.

Step 3 of 4 · Observe

Look for patterns in your observations.

Step 4 of 4 · Record

Make a graph or chart showing your results.

Question 1 of 3

What organelle produces energy for the cell?

How sure are you?😐 maybe

Question 2 of 3

How many chromosomes do human body cells have?

How sure are you?😐 maybe

Question 3 of 3

Which structure is found in plant cells but not animal cells?

How sure are you?😐 maybe

Mind = blown

🔬 The more you look, the more nature shows you.

Nice work!

You got 0 of 3 right.
