1.2 - Respiration and combustion

Text

HW Q6

Lichen - algae and fungus 

Algae - has chlorophyll = photosynthesis can take place here

          - unicellular without stem or roots

Fungus - mycelium (has roots!)

Water? 

Energy from sunluight is absorbed by? 

Photosynthesis takes place in? 

Glucose produced by photosynthesis provides energy for?

HW Q7

Plant with bright light vs plant with no light

Funnel over both - funnel filled with water

Plant produces bubbles of gas

Water level in the funnel drops

a. What gas is in the test tube?

b. Amount of CO2 same? decreased? increased?

1.2 - Respiration and combustion

Energy

Where in your body is energy needed?

And what for?

Combustion (= verbranding)

Specific form of combustion in our cells = cellular respiration

Cellular respiration: Glucose is broken down to energy and water

Cellular respiration

Glucose + oxygen -> water + carbondioxide + energy
