TEAS Biology review exam with answers
All cells arise form preexisting cells
Cells can carry out the processes of life
Organisms are made of cells that function together - ** VERIFIED ANSWERS **✔✔cell theory
The ____ is considered to be the basic unit of life - ** VERIFIED ANSWERS **✔✔cell
single cells organisms such as bacteria are examples of _____. This type of cell does not have a
nucleus,but does have DNA. ALL have a cell wall - ** VERIFIED ANSWERS **✔✔prokaryotes
multicellular organisms such as plants and animals are examples of ______
-some have a cell wall
-cell membrane present - ** VERIFIED ANSWERS **✔✔eukaryotes
The ____ of the cell is responsible for the activites of the cell regarding DNA, has its own membrane
which allows for the passage of materials and proteins needed for DNA replication - ** VERIFIED
ANSWERS **✔✔nucleus
Responsible for the production of proteins
Can be free or bound to the outer membrane of the ER - ** VERIFIED ANSWERS **✔✔ribosomes
The ____ has ribosomes attached to the outer surface, it is also produces the proteins - ** VERIFIED
ANSWERS **✔✔rough endoplasmic reticulum
The _____does not have ribosomes attached and works to transport proteins out of the cell - **
VERIFIED ANSWERS **✔✔smooth endoplasmic reticulum
____ are often termed "suicide sacs of the cell" because of their involvement with digestion within the
cell.
,-besides digesting proteins, also break down parts of the cell that are no longer needed - ** VERIFIED
ANSWERS **✔✔lysosomes
most known for their ability to store materials - ** VERIFIED ANSWERS **✔✔vacuoles
_____ are thought to be the powerhouses of the cell because of their ability to produce the energy
needed for life. - ** VERIFIED ANSWERS **✔✔mitochondria
folds of the inner membrane of the mitochondria are called ___ - ** VERIFIED ANSWERS **✔✔cristae
Present in plants, contains a substance called chlorophyll to carry out the process of photosynthesis - **
VERIFIED ANSWERS **✔✔chloroplasts
provides structure and shape to the cell - ** VERIFIED ANSWERS **✔✔cytoskeleton
these structures are not present within the cell. Instead they are located outside of the cell and allow
the cell to move - ** VERIFIED ANSWERS **✔✔cilia/flagella
Present in plant cells, the cellulose-containing ____ helps to give the plant cell rigidity - ** VERIFIED
ANSWERS **✔✔cell wall
Particles naturally move from an area of high concentration to an area of low concentration this process
is called ____. - ** VERIFIED ANSWERS **✔✔diffusion
Water can diffuse across a membrane in a process called ____ - ** VERIFIED ANSWERS **✔✔osmosis
concentration are the same inside and outside of the cell - ** VERIFIED ANSWERS **✔✔Isotonic
solution
In a _____, the solution outside the cell has a lower concentration of solutes than the solution inside the
cell. Water moves from outside solution into the cell in an attempt to dilute concentrations in the cell.
This causes the cell to ___ and/or ___ - ** VERIFIED ANSWERS **✔✔hypotonic solution, swell, burst
, In a _______, the outside solution has a high concentration of solute than the cell. Water leaves the cell
in an effort to dilute the outside solution. This causes the cell to ___, and ___ - ** VERIFIED ANSWERS
**✔✔hypertonic, shrivel, shrink
____transportation that occurs from a high concentration to a low concentration naturally and without
any additional energy input - ** VERIFIED ANSWERS **✔✔passive
_____ take place when materials need to be moved from an area of low concetration to one of high
concentration.Because this works against the natural process, the cell must use energy to carry out this
process - ** VERIFIED ANSWERS **✔✔active transport
_____molecules are carbon based - ** VERIFIED ANSWERS **✔✔organic
without carbon - ** VERIFIED ANSWERS **✔✔inorganic
Examples of ____ include lipids, carbohydrates, proteins, and nucleic acids. - ** VERIFIED ANSWERS
**✔✔organic
Examples of _____ substances include ions, iron, calcium and water - ** VERIFIED ANSWERS
**✔✔inorganic
_____ is considered to be the universal solvent and can dissolve a large range of substance that are
polar or contain ions - ** VERIFIED ANSWERS **✔✔water
forces between the same molecules - ** VERIFIED ANSWERS **✔✔cohesive forces
forces between different molecules - ** VERIFIED ANSWERS **✔✔adhesive forces
____are organic compounds that contain carbon, oxygen and hydrogen. They are major sources of
energy in the body. - ** VERIFIED ANSWERS **✔✔carbohydrates
