A 1.46 g B 1.63 g C 1.20 g

Therefore the relative dry biomass at the end of the experiment is... B>A>C

Answer each of the questions below, making sure you are using the following words and phrases –

photosynthesis, cellular respiration, taking in carbon dioxide, giving off carbon dioxide, chlorophyll, leaves, energy, mass, water, glucose/carbohydrates/polysaccharides/sugars, ATP, sunlight, chloroplast, mitochondria.

About the Radish Experiment...

• Three batches of radish seeds – each weighing 1.5 g – were weighed out. • The following experimental treatments were done:

A. Seeds not moistened (left DRY) placed in LIGHT B. Seeds placed on moistened paper towels in LIGHT C. Seeds placed on moistened paper towels in DARK

• After 1 week, all plant material was dried in an oven overnight (no water was left) and the plant’s dry biomass was measured in grams on a scale.

Note: Dry biomass is the weight of all the molecules in a living thing after water is removed through drying.

1. As a thoughtful biologist, make your best prediction about what the relative dry biomass of the plant material in each of the three treatments will be at the end of the experiment. Your prediction should be a simple equation, using symbols like >, <, = between A, B, C.

2. Write an explanation of why you made the predictions you did. Use your knowledge of biology – and carefully – use the language of biology including terms like: mass, energy, sugar, carbohydrates, glucose, carbon dioxide, sunlight, chlorophyll, photosynthesis, cellular respiration, and more...

3. Write a statement about how confident you are in your prediction and explanation.
