Cellular Respiration

Lab Brief #1

🎯 Your mission

Master the concept. Use it tomorrow.

⚡ The twist

Living things break the rules of non-living things — find the rule they break.

What you'll learn

Cellular respiration is how cells release energy from food by combining glucose with oxygen. This process takes place mainly in the mitochondria and produces carbon dioxide and water as waste, along with the energy cells need to work.

Key words

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

Make a hypothesis first

Predict: what will happen to the plant if you change the water?

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

Create a detailed food web for a local ecosystem. Include at least 8 organisms and use arrows to show energy flow from producers to top predators.

Step 3 of 4 · Observe

Note any unexpected results and think about why they happened.

Step 4 of 4 · Record

Share your findings with the class or a partner and discuss what you learned.

Question 1 of 3

What is the main source of energy for most food chains?

How sure are you?😐 maybe

Question 2 of 3

What gas do plants release during photosynthesis?

How sure are you?😐 maybe

Question 3 of 3

What organism produces food at the base of most food chains?

How sure are you?😐 maybe

Mind = blown

🌳 Trees can talk to each other through underground fungus networks.

Nice work!

You got 0 of 3 right.
