I Know Anatomy
Selectively permeable membrane (allows only certain substances through) made of phospholipids and proteins surrounding the entire cell
Plasma Membrane
Elongated, rod-shaped bodies filled with fluid, containing DNA
Known as the “power plant” of the cell
Mitochondria
Pair of rod-shaped bodies made of microtubules found near the nucleus
Centrioles
Contains many suspended organelles, or cell structures
Medium for chemical reactions
Cytoplasm
“Packaging and shipping plant” of the cell
Packages and releases materials secreted by the cell for external use
Forms lysosomes for use within the cell
Golgi apparatus
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
Cytoplasm
Small granules of RNA found in the nucleolus or cytoplasm
Ribosomes
Short, hair-like microtubules projecting from the cell membrane
Cilia
Protein synthesis for both internal and external use
Ribosomes
Digest waste materials including damaged materials found in the cell, old cell components, and materials entering the cell
Lysosomes
Large, spherical body near the center of the cell containing genetic material in the form of DNA
Nucleus
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)
Endoplasmic reticulum
Long, hair-like microtubules, projecting from the cell membrane
Flagella
Convert nutrients into energy for use by the cell/body; create adenosine triphosphate (ATP)
Mitochondria
Participate in cell reproduction through the distribution of DNA to new cells
Centrioles
Double-layered, porous membrane surrounding the nucleus
Nuclear membrane
Four to six flat membranous sacs, connected to the endoplasmic reticulum; typically found near the nucleus
Golgi apparatus
Separates the internal components of the cell from the surrounding environment
Essential to the life of the cell
Plasma membrane
Transports materials throughout the cell
RER: Supports the synthesis and transport of proteins
SER: Supports the synthesis of some lipid molecules, including steroids
Endoplasmic reticulum
Aid in the movement of substances along the surface of the cell
Cilia
Dark, dense body within the nucleus without an enclosing membrane; most cells contain one to four
Nucleolus
Sacs surrounded by membranes created by the Golgi apparatus
Lysosomes
Control center of the cell
Regulates cell activity
Houses genetic material
Nucleus
Protects the nucleus, allowing in only specific materials
Nuclear membrane
Move the cell itself, through a whip-like motion
Flagella
