Now that you know what plants need to perform photosynthesis, let’s figure out how to
put the ingredients in to get the products! Use the steps to fill in the diagram below with
the correct ingredient (reactant) or product.
1. Photosynthesis begins at the roots of the plants. The roots suck up water from the
ground which is then transported to the chloroplast through a complex set of tubs in the
plants. Kind of like straws!
What did the chloroplast take in?
2. Next the plant absorbs energy from sunlight with the help of a green pigment called
chlorophyll that is located inside the chloroplast. This solar energy is turned into
chemical energy for the plant called ATP. What was absorbed by the chlorophyll?
3. The energy from the sunlight breaks down water in the leaves and breaks it into
oxygen and hydrogen. The plant uses the hydrogen later to help it grow and the oxygen is
released into the air.
What product did the plant expel?
4. Then the carbon dioxide (a gas animals give off when they breathe) from the air is
absorbed into the leaves through tiny pores called stomata. What is entering the leaves?
5. The hydrogen left in the chloroplast blends with the carbon dioxide in the cells of the
leaves to create food for the plant in the form of glucose. The plant stores the sugar in its
leaves, stems and roots. What is the plants food source?

Cellular Respiration: Why do we eat and breathe?
Use the reading to help you fill in the diagram: Focus on what molecules go into cellular respiration and what
products come out.
1. We breathe because we need oxygen (O2) in order for our bodies to create ATP (energy). Oxygen is taken in
through the lungs, added to your blood and is transported to every living cell in your body. Once in the cell, oxygen
is taken to the mitochondria for part of an important process known as cellular respiration.
2. Another important molecule our body needs in order to perform cellular respiration is glucose (sugar). How do we
get glucose? BY EATING! When you eat, the food travels through your digestive system and is broken down into
smaller pieces known as monomers... The monomer of carbohydrates is known as glucose. Once in the blood,
glucose transported to all of the cells in your body to be broken down and combined with oxygen.
3. The mitochondria uses the oxygen

put, ATP is like the electricity in batteries and the mitochondria is like the battery itself. It is required for every
muscle in your body to move, cellular process like protein synthesis, and active transport in cellular membranes.
4. Carbon dioxide (CO2) byproduct of cellular respiration. This gas is taken from your cells by your bloodstream and
transported to the lungs to be released from the body when you breathe out.
5. A small amount of water (H2O) is also produced from this reaction as well.
