Energy
What type of energy keeps body systems running properly?
Chemical energy
In plants, photosynthesis takes place in which structure?
Chloroplast
What REACTANT of photosynthesis is found in the atmosphere in gas form?
Carbon Dioxide
What is the WASTE product of photosynthesis?
Oxygen
Which color of light is LEAST useful for a plant to perform photosynthesis?
Green (it is reflected, cannot be absorbed)
Why do plants use glucose to make sweet fruits?
To attract animals that will eat the fruit and disperse (spread) their seeds.
An organism that can make its own food is called a(n)
Autotroph
Which REACTANT of photosynthesis is found in the environment in liquid form?
Water
Which PRODUCT of photosynthesis does a plant USE for energy?
Glucose
Why do desert plants usually have small leaves and large root systems?
They need to conserve (save) water.
Which stores more energy, ATP or glucose?
Glucose
An organism that must get energy from eating other living (on once-living) organisms is called a
Heterotroph
Which type of ENERGY is needed as a reactant in photosynthesis?
Light (sunlight)
How many products result from photosynthesis and what are their names?
TWO, Glucose and Oxygen
What causes the colors that our eyes see?
The pigments that an object REFLECTS.
What type of chemical stores energy for a SHORT period of time?
ATP
The pigments needed for photosynthesis are found in which organelle?
Chroloplast
Which of the following does NOT have an effect on photosynthesis?
a.) Availability of water
b.) Size of the plant
c.) Light intensity
b.) Size of the plant
Name two ways in which plants use glucose.
1. For energy
2. For storage in the form of starch
3. For structure
4. For attracting pollinators
5. For attracting animals to eat fruit & spread seeds.
Based on the colors that chlorophyll absorbs most, plants grow best when exposed to which types/colors of light?
Red and blue light.
Where does the energy needed to make ATP come from?
ATP comes from the food animals eat.
What is the NAME of the pigment that makes plants appear green?
Chlorophyll
What is the first step in the process of photosynthesis?
The absorption of light energy.
What are the name of the two reactions that work together for photosynthesis?
Light dependent and light independent reactions.
What would happen to life on Earth if there were no autotrophs and WHY would this happen? Be specific!
If there were no plants, all other life would die because there would be nothing to perform photosynthesis. Since oxygen is produced by photosynthesis, all animal life depending on oxygen would die. There would also be no food being made for other animals to consume.
