Function - Body structure/Organ System Flashcards
What is the plasma membrane?
Separates the internal components of the cell from the surrounding environment.
Essential to the life of the cell.
What does the cytoplasm contain?
Contains many suspended organelles, or cell structures.
Medium for chemical reactions.
What is the function of the nucleus?
Control center of the cell.
Regulates cell activity and houses genetic material.
What is the role of the nuclear membrane?
Protects the nucleus, allowing in only specific materials.
What does the nucleolus do?
Forms RNA and ribosomes.
What is the function of mitochondria?
Convert nutrients into energy for use by the cell/body; create adenosine triphosphate (ATP).
What is the role of ribosomes?
Protein synthesis for both internal and external use.
What does the endoplasmic reticulum do?
Transports materials throughout the cell.
RER: Supports the synthesis and transport of proteins;
SER: Supports the synthesis of some lipid molecules, including steroids.
What is the function of the Golgi apparatus?
Packaging and shipping plant of the cell.
Packages and releases materials secreted by the cell for external use and forms lysosomes for use within the cell.
What do lysosomes do?
Digest waste materials including damaged materials found in the cell, old cell components, and materials entering the cell.
What is the function of the cytoskeleton?
Maintains the shape and structure of the cell.
Keeps organelles in place and moves them throughout the cell as needed.
What role do centrioles play?
Participate in cell reproduction through the distribution of DNA to new cells.
What is the function of cilia?
Aid in the movement of substances along the surface of the cell.
What do flagella do?
Move the cell itself, through a whip-like motion.
