Place Values
What is in the ones place of the number 14?
4
Write 14 div 2 as a fraction.
14/2
What are the two product of photosynthesis?
Sugar (Glucose, C6H12O6) and Oxygen gas (O2)
What are the two reactants producers use to do photosynthesis?
Water (H2) and Carbon Dioxide (CO2)
What are organisms that can produce their own food through photosynthesis called?
A producer
What is in the tenths place of 13.1?
1
What is 1.2div0.1 ?
12
Which of the two products of photosynthesis stores the carbon from the carbon dioxide?
Glucose (C6H12O6)
What is a producer's source of energy for carrying out photosynthesis?
The sun
What are chloroplasts?
The organelles in plant and other producer cells where photosynthesis takes place?
What is in the thousandths place of 2340.1234
3
What is 1.6div0.2 ?
8
Which of the two products of photosynthesis have oxygen atoms in them?
Both the glucose sugar and the oxygen gas had oxygen atoms?
Where do producers get the CO2 they need for photosynthesis?
From the air (or water) around the plant, through the leaves.
What molecule gives chloroplasts their green color and allow them to absorb sunlight?
Chlorophyll
What number is in the tens place of twenty-four hundred and sixteen?
2416
1
What is 10div0.2 ?
50
What happens to the oxygen gas that is made during photosynthesis?
It is released into the air.
How do plants absorb the water that they need to perform photosynthesis?
Through their roots from the ground
Explain how photosynthesis is important for the cycling of matter and energy through ecosystems.
It takes the energy from the sun and turns it into energy that can be used by living things to live and grow.
It helps cycle carbon, oxygen, and hydrogen atoms through different organisms in an ecosystem, which they can use to grow and build mass.
What number is in the tenths place of one and twenty-four hundredths?
1.24
2
What is 12div0.3 ?
40
What happens to the glucose sugar (C6H12O6) that is produced during photosynthesis?
It is stored in the producer of the organism that created it to be used for energy or to help build new cells by being turned into cellulose to create more cells so that organism can grow. It may also be turned into starch or other molecules for the energy to be stored.
How many carbon dioxide (CO2) molecules are necessary to produce one molecule of glucose?
6
What can plant cells do with the sugar they produce through photosynthesis?
They can use it for energy, they can turn it into starch and other molecules to store energy for later, and they can use it to form cellulose, which is the substance that cell walls are made of.
