|
Flagella
|
How to identify:
long, less numerous hairlike organelles that extend from the surface of a cell Function: assist in movement. |
|
|
Cilia
|
How to identify:
short, more numerous hairlike organelles that extend from the surface of the cell Function: assist in movement of the cell, trap tiny particles and debri |
|
|
Spindle Fibers
|
How to identify:
bundles of microtubules that come together and extend across the cell |
|
|
Microtubule
|
How to identify:
Largest strands of cytoskeleton, hollow tubes. Extend outward from a central point near the nucleus to sites near the cell membrane. |
|
|
Microfilament
|
How to identify:
Smallest strands that make up cytoskleton. Threads made of protien that contrbute to cell movement and play a role in the contraction of muscle cells. |
|
|
Lysosomes
|
How to identify:
small spherical organelles that enclose enzymes with single membranes. Function: digest proteins, carbohydrates, lipds, DNA, and RNA |
|
|
Golgi Apparatus
|
How to identify:
series of flattened sacs with characteristics of a convex shape in cytosol. Function: modifies proteins for export by the cell and is the processing, packaging, and secreting organelle of the cell |
|
|
Smooth ER
|
How to identify:
not covered in ribosomes and appears smooth Function: involved in the synthesis of steriods in gland cells, regulatioin of calcium levels in muscle cells, and the breakdown of toxic substances by liver cells. |
|
|
Rough ER
|
How to identify:
covered in ribosomes which gives it the rough appearance Function: prominent in the cells that make a large amount of proteins to be exported from the cell or inserted into the cell membrane |
|
|
Ribosomes
|
How to identify:
most numerous organelle of the cell and are not surrounded by a membrane, made of protiens and RNA some remain from within cytosol while others are attatched to ER. Function: play important role in synthesis of proteins, produces the proteins that need to be inserted into membranes or exported from the cells when attached to ER |
|
|
Mitochondria
|
How to identify:
relatively large organelle scattered throughout cytosol with two membranes Function: where energy in the form of ATP is produced |
|
|
Cytosol
|
How to identify:
gelatin-like aqueos fluid that organelles are bathed in |
|
|
Cytoplasm
|
How to identify:
contains the various organelles of the cell and is located between the cell membrane and the nucleus |
|
|
Nucleus
|
How to identify:
control center of the cell which is surrounded by a double membrane Function: stores hereditary information in DNA and also copies RNA from DNA |
|
|
Chromatin
|
How to identify:
fine strands that appear inside the nuclear envelope |
|
|
Nuclear Matrix
|
How to identify:
protein skeleton that helps the nucleus maintain its shape |
|
|
Nucleolus
|
How to identify:
small circular structures within the nucleus which may be involved in protein synthesis |
