eukaryotic cell structure

study for unit exam 1 and 1 lab pratical

nucleus

all dna is housed to give instructions

nucleus

between the nucleus envelope creates ribosomes

nuclear envelope

double layered membrane that protects the nucleolus and the nucleus

peroxisomes

breaks down fatty acid into hydrogen peroxide that breaks down into water and oxygen

plasma membrane

the shell of the cell, protects all of the organelles and controls what molecules enter and exit

ribosomes

proteins are synthesized creating different forms of amino acid together to create the proteins

rough endoplasmic reticulum

helps ribosomes bind so proteins can be made and folded properly

smooth endoplasmic reticulum

breaks down smooth carbohydrates creates llipid that are needed for the cell and regulates calcium in the muscles

secretion of exocytosis

THIS IS A FUNCTION ; toxins and other products of the cell are released along the cell membrane outside of the cell to be disposed

centrioles

works on the organization of the cell by spacing where the nucleus is compared to other organelles

centrosome matrix

helps form the microtubules

chromatin

helps dna package during mitiosis

cytosol

a skeleton for the cell to provide support and shape

intermediate filaments

helps make up the cytoskeleton usually thicker than microfilaments

microtubules

helps form the cytoskeleton for support of the cell as well as the movement of the cell

lysosomes

removes any toxic or unwanted molecules so the cell is not harmed

golgi apparatus

package proteins from the ER into transport vesicles to be carried to other parts of the cell

mitochondrion

power house of the cell, creates all energy for the cell by breaking down glucose into water oxygen and atp
