What are the parts of the plant?
Draw a picture of a plant cell.
What is cellulose?
What is the vacuole?
What are chloroplasts?
What is photosynthesis? Where does it take place inside the plant cell?
Made by Liesl at homeschoolden.com
What ingredients do chloroplasts need to make food?
Using a molecular model set, make the two molecules you wrote down above. If you don't
have a set, draw a picture of these two molecules:
What is the name of the "food" that plants make?
How many carbon atoms are there?
How many hydrogen atoms are there?
How many oxygen atoms are there?
Make a model of this molecule using a molecular model set (if you have one).
What are the products of photosynthesis?
How does water go from the roots to the top
of a tree?
How are sugars moved from the leaves to all of the cells in the plant and to the
roots?

What are the parts of the plant?
Terminal bud, stem, leaves, roots, root hairs, fruit (and/or flower)
Draw a picture of a plant cell. Answers can contain any of the following:
What is cellulose?
The main component of plant cell walls that gives plants their strength
What is the vacuole?
These are like storage containers in plant cells for food, water and nutrients
What are chloroplasts?
This is where plants make food
What is photosynthesis? Where does it take place inside the plant cell?
This is the process of chloroplasts making food using sunlight energy.
What ingredients do chloroplasts need to make food? carbon dioxide (CO2) and
water (H2O).

What is the name of the "food" that plants make? glucose
How many carbon atoms are there? 6
How many hydrogen atoms are there? 12
How many oxygen atoms are there? 6
Make a model of this molecule using a molecular model set (if you have one).
Since we are not studying chemistry at the moment, we quickly reviewed
some chemistry basics and went over the chemical bonding again with this
explanation of happy atoms over at:

Water molecule
Carbon Dioxide molecule
What are the products of photosynthesis? Glucose and oxygen
How does water go from the roots to the top of a tree? Water moves through xylem
How are sugars moved from the leaves to all of the cells in the plant and to the
roots? Sugars move through phloem.
Oxygen is known as O and has 2 bond/s.
Carbon is known as C and has 4 bond/s.
Hydrogen is known as H and has 1 bond/s.
Here are the activities we did to show how the molecules from carbon dioxide

and water form the basis for glucose and oxygen molecules:
We used the Molymod Organic Chemistry Model Kit.
