What is the role of the cell nucleus?
The nucleus contains nearly all the cell's DNA and, with it, coded instructions for making proteins and other important molecules.
specialized organs or "little organs"
Store materials like water, salts, proteins and carbohydrates.
Store and move materials between organelles, as well as to and from the cell surface.
Small organelles filled with enzymes. Breaks down lipids, carbohydrates, and proteins into small molecules so that it can be used for the cell. They also involve in breaking down organelles that have outlived their usefulness.
Eukaryotic cells are given their shape and internal organization by a network of protein filaments. Helps the cell maintain shape and also involves movement.
threadlike structures made up of a protein called actin. These help cells move and allow amoebas and other cells to crawl along surfaces.
hollow structures that are made of proteins known as tubulins. Play an important role in cell division as it is the structure known as the mitotic spindle.
Helps separate chromosomes in cell division
Located near the nucleus and help organize cell division.
Where proteins are assembled.Are small particles of RNA and protein found throughout the cytoplasm in all cells. Produce protein by following coded instructions that come from DNA
Proteins produced in the Rough ER move to this organelle. It modifies, sorts and packages proteins and other materials from the endoplasmic reticulum.
Where lipid components of the cell membrane are assembled along with the proteins and other materials that are exported from the cell.
Involved with the synthesis of proteins. Ribosomes are found on its surface, thus, giving it its name.
Contains collections of enzymes that perform specialized tasks, including the synthesis of proteins and detoxification of drugs.
Capture energy from sunlight and convert into food that contains chemical energy in a process called photosynthesis.
Convert the chemical energy stored in food into compounds that are more convenient for the cell to use.
It regulates what enters and leaves the cell and also protects and supports the cell.
Provide much of the strength needed for plants to stand the force of gravity. It is also a strong supporting barrier around the membrane.
Gives cell membrane a flexible structure that forms a strong barrier between the cell and its surroundings.
