Single cells grow and [blank_start]divide[blank_end] to form more cells in a process called the [blank_start]cell cycle[blank_end].
A [blank_start]young[blank_end] cell undergoes cell division which promotes cell growth. The cells can then either grow into more stem cells or develop into specialized cells which in turn develop into [blank_start]mature[blank_end] cells.
[blank_start]Embryonic[blank_end] development causes many cells to [blank_start]lose[blank_end] the ability to divide as they develop into the tissues and organs that make up organisms. The cells that retain many embryonic properties are called [blank_start]adult[blank_end] stem cells.
Flagella is for the mobility of the cell and pili is for the attachment to other cells.
Flagella is for the attachment to other cells and pili is for the mobility of the cell.
Flagella is for nuclear division and pili is for structure
Flagella is for structure and pili is for nuclear division
Which of the following are organelles are present in prokaryotes but not eukaryotes?
Which of the following are fundamental statements of cell theory?
Cells come only from other cells
Cells maximize their SA;Vol ratio
All living things consist of cells
Cells are the smallest units of life
Which part of the plasma membrane is involved in recognition of other cells?
How do animals use cholesterol?
To store energy
To form part of the plasma membrane
To insulate neurons (nerve cells)
To increase blood pressure
Which cell organelle is responsible for the production of proteins to be exported from the cell?
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
By which method do prokaryotes reproduce?
ANSWER: [blank_start]binary[blank_end] [blank_start]fission[blank_end]
Prokaryotes do not have a mitochondrion
Complete the following statement using the correct numbers. (Use numbers not words. Ex: 15 not fiveteen)
Eukaryotes have [blank_start]80[blank_end]s ribosomes and Prokaryotes have [blank_start]70[blank_end]s ribosomes.
Which of the following is true for a ribosome?
It is responsible for the breakdown of the contents of "food" vacuoles
It is responsible for protein synthesis
It is responsible for packaging and sending off proteins
An animal cell is placed in a hypotonic (very weak) sugar solution and therefore the cell will decrease in mass.
Osmosis is the movement of [blank_start]water[blank_end]
Diffusion is the movement of [blank_start]liquids and gases[blank_end]
liquids and gases
The smaller the size of a cell the less surface area to volume it has.
Which of the following does 'surface to volume ratio' determine?
The amount of absorption that occurs
How long heat energy takes to get in or out
Which of the following types of transport moves from a low concentration to a high concentration?
Decode the following DNA to mRNA
DNA --> TAC CTC CGG TGG GTG CTT GTC TGT ATC
mRNA->[blank_start]AUG[blank_end] [blank_start]GAG[blank_end] [blank_start]ACC[blank_end] [blank_start]ACC[blank_end] [blank_start]CAC[blank_end] [blank_start]GAA[blank_end] [blank_start]CAG[blank_end] [blank_start]ACA[blank_end] [blank_start]UAG[blank_end]
[blank_start]A[blank_end][blank_start]U[blank_end][blank_start]G[blank_end] is the start codon
[blank_start]U[blank_end][blank_start]A[blank_end][blank_start]G[blank_end] is the end codon
Where does the first step of protein synthesis occur?
The bases on tRNA are called...
Drag the function to the correct primase, polymerase, and ligase:
- RNA primase; forms short lengths of [blank_start]RNA[blank_end] primer at intervals [blank_start]along the DNA strand[blank_end]
- DNA polymerase III; [blank_start]forms[blank_end] short [blank_start]DNA[blank_end] strands called Okazaki Fragments[blank_start], starting from each RNA primer[blank_end]
- DNA polymerase I; [blank_start]replaces[blank_end] the [blank_start]RNA primer[blank_end] at the start of each Okazaki Fragment with a [blank_start]DNA strand[blank_end]
- ligase; [blank_start]joins the DNA strands together[blank_end]
