What statement was originally part of the cell theory, but later removed due to further research?
Cells form through spontaneous generation.
Which invention from the 17th century allowed for the development of modern cell
The light microscope.
A plant and an animal are both living things, according to the cell theory what can you conclude about these two different organisms.
They are both made out of one or more cell.
Which structures to eukaryotic cells and prokaryotic cells share
Howare prokaryotic and eukaryotic cells different?
Prokaryotic lack a nucleus
What is it called when H+ ions are being pumped from a low to high concentration?
What types of cells have genetic material that is contained in a nucleus?
Both plant and animal cells.
What is the ribosomes primary function?
If someone with swollen gums rinses his mouth out with warm salt water and the swelling decreases, what has occurred?
The water in the gums would have moved out due to the high concentration of salt in the solution.
In a cell, which organelle provides the site where amino acids are synthesized into proteins?
The rough ER
Substances that are blocked from entering a cell membrane are known as...
How does a muscle cell differ from other types of cells?
The muscle cell would have more mitochondria than other animal cells
What type of cell would contain a nucleus, lysosomes, a cell membrane and a cell wall?
A eukaryotic plant cell.
Which of the following contain complex, membrane bound organells? 1. bacteria . viruses 3.eukaryotic 4.prokaryotic
What is the advantage of cells being so small?
The cells then have a larger surface area to volume ratio which means it can move nutrients into the cell and waste out more efficiently
What are the advantages of having folded membranes that contain ribosomes in the endoplasmic reticulum
This increases the surface area so more proteins are produced.
What would occur if a cells lysosomes were damaged?
The cell would be less able to break down molecules in its cytoplasm.
What is used to pump antibiotics out of their cells?
Which structure is responsible a plant cell not swelling and bursting when placed in water, such as a red blood cell would do?
The cell wall
Which of the following functions does active transport perform in a cell?
moving substances against a concentration gradient.
What happens to red blood cells when placed in distilled water
They would burst and could cause fatal side effects.
What is an independant variable?
The variable whose variation does not depend on anything else.
