1
New cards
What is a cell?
The smallest unit of life. All living things are made of cells.
2
New cards
What is a tissue?
A group of similar cells working together (e.g. muscle tissue).
3
New cards
What is an organ?
Several tissues working together to do a job (e.g. the heart, a leaf).
4
New cards
What is an organ system?
Several organs working together (e.g. the respiratory system).
5
New cards
What is an organism?
The whole living thing.
6
New cards
What is cellular respiration?
The reaction that releases energy from food inside every living cell.
7
New cards
Where does cellular respiration happen?
In the mitochondria.
8
New cards
What is breathing?
Moving air in and out of the lungs.
9
New cards
Is breathing the same as respiration?
No. Breathing is moving air in and out of the lungs, while cellular respiration is the reaction that releases energy from food inside every living cell.
10
New cards
What is the order of levels of organisation from smallest to largest?
Cell → tissue → organ → organ system → organism.
11
New cards
What are the reactants in cellular respiration?
Glucose + oxygen.
12
New cards
What are the products of cellular respiration?
Carbon dioxide + water + energy.
13
New cards
What is the equation for cellular respiration?
Glucose + oxygen → carbon dioxide + water + ENERGY.
14
New cards
What is photosynthesis described as in the revision sheet?
The reverse of cellular respiration.
15
New cards
What is the equation for photosynthesis?
Carbon dioxide + water → glucose + oxygen.
