Cell Strucure Flashcards
What are organelles
Structures within a cell
What is cytoplasm?
Portion of cell outside the nucleus
What is the role of the cell’s nucleus?
Contains nearly all the cell’s DNA and with it the coded instructions for making proteins and other important molecules
What are the functions of vacuoles?
Vacuoles store materials like water, salts, proteins, and carbohydrates
What are the functions of lysosomes?
Break down lipids, carbohydrates and proteins into small molecules that can be used by the rest of the cell. They also break down organelles that have outlived uselfulness
What are the functions of the cytoskeleton?
Helps maintain the cell’s shape and movement
What are the functions of centrioles?
help organize cell division
What are the functions of ribosomes (small particles of RNA)?
Assembly of proteins (occurs right on them)
What are the functions of endoplasmic reticulum?
Prepare proteins to be released from the cell
What are the functions of the Golgi Apparatus?
Modifying, sorts, and packages proteins and other materials for storage in the cell or release outside the cell
What are the functions of the chloroplast (plants)?
Capture the energy from sunlight and convert it into food
What are the functions of the mitochondria (animal)?
Convert chemical energy stored in food into compounds that are more confine for the cell use
What are the functions of the cell wall?
Strong supporting layer around the membrane
What are the functions of the cell membrane?
Regulates what enters and leaves the cell and also protects and supports the cell
Why are cell membranes made of a lipid bilayer
Gives the cell flexible structure that is also strong barrier
