is the process that allows both plants and animals to use food molecules for energy.
is the process that allows both plants and animals to use food molecules for energy.
Glucose is a subunit of .
During O2 reacts with food molecules to create the new products of CO2 and .
An ecosystem needs a constant input of energy. As this energy enters the environment, plants use it in to create molecules. These molecules are then used by in to produce energy for cells.
Identify each statement as a characteristic of photosynthesis or cellular respiration by selecting the bubble in the correct column.
Photosynthesis | Cellular Respiration | |
|---|---|---|
Makes glucose | ||
Captures light energy | ||
Uses oxygen | ||
Occurs in all organisms | ||
Uses food molecules | ||
Occurs only in plants |
ALL food molecules contain atoms of these THREE elements:
All food sources can be traced back to plants.
The purpose of cellular respiration is to make food molecules.
Carbon cycles between organisms in the environment. Plants take in their carbon as and animals take in their carbon as .
When do plants do photosynthesis?
Identify each item as describing either carbohydrates, proteins, or fats.
Carbohydrates | Proteins | Fats | |
|---|---|---|---|
Has the most Calories per gram. | |||
Often has rings. Starch and glucose are an example | |||
Has Nitrogen atoms. |
Different types of food molecules, when reacting with , provide different amounts of energy.
Where does most of the matter that makes up plants originally come from? (hint: more than one answer)
A closed terrarium is a container in which a plant lives and grows in its own micro-ecosystem. After it is first set up and put in a sunny location, it can live for many years without the need to add more water or nutrients.
Explain how a plant can live like this.
Make sure to describe the role of photosynthesis and cellular respiration in your answer.
The following is the equation for photosynthesis:
-->
How does the human body store energy when it is not needed right away?
Why do you have to eat even when you are done growing?
