LAPTOP ACTIVITY: ILLUMINATING PHOTOSYNTHESIS
This feature reveals the secret of life, or at least it reveals a small bit. It shows how a plant uses light
from the sun and from this how we all benefit.
It shows you how plants create glucose. It shows you the cycle of gases. It asks you some relevant questions
that make think about how plants and animals work together.

Atomic Shuffle
1. Draw each of the following molecules: carbon dioxide, hydrogen, water, oxygen, and glucose. Be sure
to put the name of each below:
2. Write a description of the process of photosynthesis in your own words.___________________

Three Puzzlers
1. A tree inhales CO2 it needs to if it is to survive. But can it release enough O2 to keep just one person
alive? ______________________________________________________________________
2. A plant needs its own food to function. It can’t make its own food at night. Beyond a few hours of
darkness can a plant stay alive with out light? _________________________________________
3. A plant receives the nutrition it needs will continue to live, we now know. But what if we took all of its
O2 away? Do you think the plant could still grow? _______________________________________
