Why do cells need a microscope to be seen?
Because they are extremely small.
What do red blood cells carry?
Oxygen.
What do plants grow toward?
Sunlight.
What happens when cells group together?
They form tissues and organs.
Why would your skin not look smooth if you zoomed in?
Because it is made of millions of cells.
What are cells compared to in the “busy city” description?
Living building blocks or tiny workers.
What is blood compared to in the article?
A moving river.
What do green structures in leaves capture?
Sunlight.
What comparison is used to explain cells working together?
A team sport.
Why can’t plants hunt for food?
Because they cannot move like animals.
Why don’t all cells look the same?

What happens in your body when you get a small scrape?
Cells rush in, clots form, and new skin grows.
What do leaves turn sunlight into?

What do cells build when they form teams?
Machines (organs and systems).
What advantage does having many tiny air spaces in the lungs provide?
A large surface area for gas exchange.
Give one job of a specialised cell mentioned in the article.
Carry oxygen / send signals / help movement.
Why don’t you need to remind your heart to pump?

What is one job of plant roots besides anchoring the plant?
Absorbing water and minerals.
Name one job of a body system mentioned in the article.

What two extra jobs does blood do besides carrying oxygen?
Fighting germs and forming clots.
What big idea explains why a cell’s structure matches its job?
Structure and function are linked.
Why are lungs packed with millions of tiny air spaces?
To increase surface area for oxygen absorption.
What is the difference between xylem and phloem?
Xylem transports water; phloem transports food.
Why are living organisms described as organised rather than random?
Because every part has a specific purpose.
According to the article, what do you become when viewed at the cellular level?
