2. Fill in the blanks regarding the different cell structures by clicking on their names
and reading about them.
Nucleus:
The nucleus is the most ________________ organelle in any eukaryotic
cell. Within the nucleus is the __________ which is responsible for
providing the cell with it unique characteristics. When the cell is dividing
the DNA condenses into ______________________.
Nucleolus:
The nucleolus produces _______________________.
Cytosol:
The cytosol is the _____________ in which the other cell organelles
reside and where most of the cellular metabolism occurs.
Centrosome/Centrioles: During animal cell division the centrioles
___________________ and the centrosome _________________.
Golgi:
The Golgi apparatus is a ___________________ of membrane bound
vesicles that are important in packaging ___________________ for
transport.
Lysosomes: Lysosomes contain hydrolytic _________________ necessary for
intracellular _____________________.
Peroxisomes: These organelles are responsible for ____________________ the cell
from its own production of toxic ___________________________. The
enzymes in peroxisomes break hydrogen peroxide down into
_______________ and ________________.
Secretory Vesicles: Cell secretions such as ________________, _______________
and _________________ are packaged in secretory vesicles at the Golgi
apparatus.
Cell Membrane: Every cell is enclosed by a double layer of _____________________.
The exposed heads are ___________________ (water loving) and
the hidden tails are _____________________ (water fearing). The
hydrophilic heads means that they are ___________________ with
____________ both within the ______________ and outside the
cell. The hydrophobic tails allows the cell membrane to act as a
__________________ barrier to the uncontrolled flow of
__________________.
Label the cell membrane below with the following terms:
hydrophobic tails
Mitochondrion:
protein
hydrophilic heads
cytosol
Mitochondria provide the energy a cell needs to
________________, ___________________,
____________________, ____________________, in
short they are the ___________________ centers of the
cell.
Vacuole: A vacuole is a membrane bound sac that plays a role in
intracellular____________________ and the release of cellular
___________________. In animals the vacuoles are generally
______________.
Vacuoles tend to be ____________ in plant cells and play several
roles:____________ nutrients and waste products, helping increase
cell size during ________________, and even acting much like
__________________ of animal cells. The plant cell vacuole also
regulates _____________ pressure in the cell. Water
________________ in cell vacuoles, pressing outward against the cell
wall and producing ______________ in the plant. Without sufficient
water, turgor pressure _____________ and the plant ___________.
Smooth Endoplasmic Reticulum: The ER is a vast network of membrane-bound
__________________ and __________________.
Its function differs depending on type of _________________. It
could be involved in the synthesis of ________________ and
_________________ or the break-down of lipid-soluble
_____________ in the liver cells and the control of
________________ release in muscle cell contraction.
Rough Endoplasmic Reticulum: Rough ER appears pebbled because of the
presence of __________________ on its surface.
______________synthesized on these ribosomes collect in
the ER for transport throughout the cell.
Ribosomes: Ribosomes are the site of ________________ synthesis.
________________ RNA from the cell’s nucleus is moved
systematically along the ribosome where
_____________________ RNA adds individual
__________________ __________________ molecules to
the lengthening __________________ chain.
Label the following image with the following terms:
messenger RNA
Cytoskeleton:
protein
transfer RNA
amino acid
ribosome
The cytoskeleton helps the cell to maintain its _______________.
But the primary importance of the cytoskeleton is in cell
________________.
Chloroplast (plant cells only): Chloroplasts are specialized organelles found in all
complex plant cells. These organelles contain the plant cell's
________________ responsible for the plant's _______________ color
and are involved in the light capturing, food producing process called
__________________.
Cell Wall (plant cells only): Plant cells have a rigid, ______________ cell wall made up
of polysaccharides. In complex plant cells, that polysaccharide is
_______________. The cell wall provides and maintains the
_____________ of these cells and serves as a ___________________
barrier.
