VFound mainly in plants and protists, these are liquid-filled cavities enclosed by a single membrane. They serve as storage bins for food and waste products. Contractile versions of these organelles are important for freshwater protists to rid their cells of excess water that accumulates because of salt imbalance with the environment.
GThe stack of flattened, folded membranes that forms this organelle acts as the 'post office of the cell.' Here proteins from the ribosomes are stored, chemically modified, 'addressed' with carbohydrate tags, and packaged in vesicles for delivery.
FThese are important organelles of motility, which allow the cell to move. These are long, whip-like structures. These organelles contain a 9 + 2 arrangement of microtubules in cross section and are powered by molecular motors of kinesin and dynein molecules.
MThey are the powerhouses of the cell. They are double-membrane-bound organelles that are the site of respiration and oxidative phosphorylation, processes that produce energy for the cell in the form of ATP. The inner membrane of one forms folds called cristae [KRIS-tee], which are suspended in a fluid called the matrix. The matrix contains DNA and ribosomes.
LThese are membrane-bound organelles that contain digestive enzymes that break down proteins, lipids, carbohydrates, and nucleic acids. They are important in processing the contents of vesicles taken in from outside the cell. It is crucial to maintain the integrity of their membranes because the enzymes they contain can digest cellular components as well.
CFound only in plants and certain protists, this organelle contains the green pigment chlorophyll and is the site of photosynthesis. Like the mitochondrion, this is a double-membrane-bound organelle, and it has its own DNA and ribosomes in the stroma. They contain grana, which are stacks of single membrane structures called thylakoids on which the reactions of photosynthesis occur.
RThese are the machines that coordinate protein synthesis, or translation. They consist of several RNA and protein molecules arranged into two subunits. They read the messenger RNA copy of the DNA and assemble the appropriate amino acids into protein chains.
NThis is the 'command central' of the cell because it contains almost all of the cell's DNA, which encodes the information needed to make all the proteins that the cell uses. The DNA appears as chromatin through most of the cell cycle but condenses to form chromosomes when the cell is undergoing mitosis. Commonly seen within this are dense bodies called nucleoli, which contain ribosomal RNA. In eukaryotes, this is surrounded by a selectively-permeable envelope.
CNot found in plant cells, these are paired organelles with nine sets of microtubule triplets in cross section. They are important in organizing the microtubule spindle needed to move the chromosomes during mitosis.
EThis is a network of tube-like membranes continuous with the nuclear envelope that comes in rough (with ribosomes) and smooth (without ribosomes) varieties. In this, proteins undergo modifications and folding to yield the final, functional protein structures.
CThese are important organelles of motility, which allow the cell to move. These are short hair-like projections. These organelles contain a 9 + 2 arrangement of microtubules in cross section and are powered by molecular motors of kinesin and dynein molecules.
