What is the Plasma Membrane
Selectively permeable membrane made of phospholipids and proteins surrounding the entire cell.
What is the function of the plasma membrane?
Separates the internal components of the cell from the surrounding environment and is essential to the
life of the cell.
What is the Cytoplasm?
Gel-like fluid filling the inside of the cell that is comprised primarily of water, with electrolytes, metabolic
waste products, and nutrients dissolved within it.
What is the function of the cytoplasm?
Contains many suspended organelles, or cell structures and is a medium for chemical reactions.
What is the Nucleus?
Large, spherical body near the center of the cell containing genetic material in the form of DNA.
What is the function of the nucleus?
Control center of the cell, regulates cell activity, and house genetic material (DNA).
What is the Nuclear Membrane?
,Double-layered, porous membrane surrounding the nucleus.
What is the function of the nuclear membrane?
Protects the nucleus, allowing in only specific materials.
What is the Nucleolus?
Dark, dense body within the nucleus without an enclosing membrane; most cells contain one to four.
What is the function of the nucleolus?
Forms RNA and ribosomes
What is the Mitochondria?
Elongated, rod shaped bodies filled with fluid, containing DNA. Known as the "power plant" of the cell.
What is the function of the mitochondria?
Converts nutrients into energy for use by the cell/body' creates adenosine triphosphate (ATP).
What are Ribosomes?
Small granules of RNA found in the nucleolus or cytoplasm.
What is the function of ribosomes?
Protein synthesis for both internal and external use.
What is the Endoplasmic Reticulum?
Complex connection of membranous fluid-filled, flat sacs and tubular channels. Connects the cell
membrane to the nucleus membrane, as well as some organelles. Comprised of the rough endoplasmic
reticulum (RER) and smooth endoplasmic reticulum (SER).
,What is the function of the endoplasmic reticulum?
Transports materials throughout the cell.
What is the function of the rough endoplasmic reticulum (RER)?
Supports the synthesis and transport of proteins.
What is the function of the smooth endoplasmic reticulum (SER)?
Supports the synthesis of some lipid molecules, including steroids.
What is the Golgi Apparatus?
Four to five flat membranous sacs, connected to the endoplasmic reticulum; typically found near the
nucleus.
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. Forms lysosomes for sure within the cell.
What are Lysosomes?
Sacs surrounded by membrane and are created by the Golgi Apparatus?
What is the function of Lysosomes?
Digest waste materials including damaged materials found in the cell, old cell components, and materials
entering the cell.
What is the Cytoskeletan?
Comprised of protein microfilaments and microtubules.
, What is the function of the Cytoskeleton?
Maintains the shape and structure of a cell. Keeps organelles in place and moves them throughout the
cell as needed.
What are Centrioles?
A pair of rod-shaped bodies made up of microtubules found near the nucleus.
What is the function of Centrioles?
Participate in cell reproduction through the distributions of DNA to new cells.
What is Cilia?
Short, hair-like microtubules projecting from the cell membrane.
What is the function of Cilia?
Aids in the movement of substances along the surface of the cell.
What is the Flagella?
Long, hair-like microtubules, projecting for the cell membrane.
What is the function of the Flagella?
Move the cell itself, through a whip-like motion.
Which cell organelle is responsible for transporting materials throughout the cell.
Endoplasmic Reticulum
How many planes of the body are there?
Three planes
