What is DNA?
The "blueprint" in a cell that contains information to make new cells and provide instructions for making proteins
100
Is the purpose of bacteria to make us sick? Why or why not?
No, its purpose is not to make us sick. Bacteria is trying to survive which can sometimes cause us to be sick.
100
Define Osmosis
The diffusion of water from a high concentration to an area of low concentration through a cell membrane.
100
What are Carbohydrates made of?
Carbohydrates are made of sugars.
100
How many cells does a unicellular organism have?
1
200
What is a Lipid?
A type of biochemical, including fats and oils, that does not dissolve in water and stores energy.
200
Why did the food coloring diffuse quicker in warm water?
The water molecules move quicker in warm water causing the rate of diffusion to increase
200
Why did the gummy bear get smaller in honey?
The gummy bear got smaller in honey because the high concentration of water was in the bear. The low concentration of water was in the honey, so the water moved from the bear to the honey resulting in the bear decreasing in size.
200
What is the most famous example of a nucleic acid?
DNA
200
How do unicellular organisms reproduce?
Asexual reproduction
300
What is a specialized cell?
A cell in a multicellular organism that has a specific function.
300
Name an advantage for asexual reproduction
Organisms that reproduce Asexually do not need a mate, so they are not wasting/using energy to find one.
300
What happens when particles are too large to pass through the cell membrane?
There are "doorways" that allow these larger molecules to pass through.
300
What are the subunits of protein?
Amino acids
300
How does a multicellular organism get bigger?
A multicellular organism gets bigger by increasing the number of cells through cell division.
400
What is the function of a Phospholipid?
A phospholipid forms much of a cell's membrane
400
Why must organisms eat food?
Since animals do not produce food, they need to eat in order to obtain the nutrients needed for their cells to carry out their functions.
400
What is passive transport?
Passive transport is diffusion! ( the movement of particles from an area of high concentration to an area of low concentration.) It does not require energy
400
Name two functions of the lipids.
1. Store energy 2. Create the cell membrane
400
Name an advantage of sexual reproduction
An advantage for sexual reproduction is that the offspring have genetic variation which can help them survive.
500
What is Active transport?
The movement of particles from an area of low concentration to an area of high concentration.
500
How does a unicellular organism get bigger?
By obtaining nutrients that cause the single cell to increase in size.
500
What is active transport and give an example.
Active transport is the movement of particles from an area of low concentration to an area of high concentration( requires energy.) An example would be plants obtaining salt from the soil
500
What is ATP?
ATP is the major fuel used for all cell activities that require energy.
500
Name three examples of a unicellular organism
Bacteria, amoeba, protist, paramecium,and euglena.
