A living thing that gets food by consuming, or eating, other living things
A living thing that can capture energy from sunlight or chemicals to make its own food
The process by which plants and other autotrophs use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
converts light energy into chemical energy through photosynthesis
What is the function of chloroplast?
What does chlorophyll mean?
Soil, minerals, water, and light.
What do plants need to survive?
Life is based on cells
What does Cellular basis of life mean?
Photosynthesis happens at the cellular level
How does the cellular basis of life relate to the ability of some organisms to capture and use energy from the sun?
what is another name for adenosine triphosphate?
3 phosphate groups.
What are the 3 parts of ATP?
the 3 phosphate groups
What is the key to how ATP can store and release energy?
ATP uses these groups to store and release energy.
Why are the three phosphate groups important?
Adenosine diphosphate
What is ADP?
ADP only has two phosphate groups instead of three.
This is key to how living things store energy.
How is ADP different from ATP?
They break the chemical bond between the second and third phosphate group.
How do cells release energy?
ATP can easily release and store energy by breaking and re-forming the bonds between its phosphate groups.
Why is ATP useful to cells?
– Power Active Transport.
– provides energy to move material into and out of many cells.
– helps proteins in muscles to slide closer together (muscle flexing).
Name some ways that cells use ATP?
ATP is great for giving off small amounts of energy quickly, but glucose is much better for storing energy.
Why is ATP not used for long-term energy storage?
It will die.
What do you think would happen to a cell if it did not have any ATP?
Tri (meaning 3)
What part of Adenosine triphosphate tells you how many phosphate groups ATP contains?
– two.
– The prefix “di” means “two”.
How many phosphate groups does adenosine diphosphate or “ADP” have? How do you know?
They both need food to survive.
How are heterotrophs and autotrophs alike?
Heterotrophs get their food by eating other living things, but autotrophs make their own food.
How are heterotrophs and autotrophs different?
plants change the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
What happens during photosynthesis?
all living things would die without autotrophs
Why are autotrophs so important?
They produce their own food and food for other organisms
Autotrophs are also known as producers. Why?
An animal that gets its food by eating other animals is a(n) _______________.
Adenosine Triphosphate (ATP)
___________ provides a cell with energy when it loses a phosphate group.
____________ use photosynthesis to make sugars.
Mushrooms cannot make their own food. They must get it from the remains of other living things.
Why are decomposers, such as mushrooms, heterotrophs and not autotrophs?
Is a tree an autotroph or a heterotroph?
b. Grasses
Which of the following are autotrophs?
a. Deer.
b. Grasses.
c. Leopards.
d. Mushrooms.
c. Sunlight
Where do plants get the energy they need to carry out photosynthesis?
a. Air.
b. Soil.
c. Sunlight.
d. Water.
Glucose stores much more energy than ATP stores. However, ATP is more easily used as an immediate source of energy for the cell.
How does a molecule of ATP compare to a molecule of glucose in terms of the amount of energy stored?
