How can we define it?

Growth Reproduce Homeostasis Response to

stimuli Metabolism

The set of chemical reactions that happen in living organisms in order to maintain life

By the end of today you will…

Understand these chemical reactions Know why and where these chemical

reactions occur Have observed these reactions through

experimentation Be able to list several factors that effect

these reactions

Plants Animals

Photosynthesiswater + sunlight + Carbon dioxide

sugar + oxygen

Respirationsugar + oxygen water + energy +

carbon dioxide

What do organisms use energy for? Growth, reproduction, maintaining homeostasis

To Live!!

Genus of aquatic plants Live entirely under

water

Photosynthesis Q: what is the effect

of light intensity on the rate of photosynthesis?

Unicellular fungi eukaryote 1,500 species

Respiration Q: What is the effect

of sugar concentration on respiration?

5 sugar concentrations: 0% 0.5% 1% 4% 10%

For the x axis: choose either time or sugar concentration

For the y axis: choose either bubble height or balloon circumference
