Front Back

-region where the cells microtubules are initiated
-contains a pair of centrioles


-network of membraneous sacs and tubes
-active in membrane synthesis and other synthetic and metabolic processes

endoplasmic recticulum

-double membrane enclosing the nucleus
-perforated by pores continuous with ER

nuclear envelope

-nonmembraneous structure involved in production of ribosomes
- a nucleus has one or more nucleoli


-material consisting of DNA and proteins
-visible in a dividing cell as individual condensed chromosomes


membrane enclosing the cell

plasma membrane

-complexes that make proteins
-free in cytosol or bound to rough ER or nuclear envelope


organelle active in synthesis modification sorting and secretion of cell products

Golgi apparatus

digestive organelles where micro molecules are hydrolyzed


organelle where cellular respiration occurs and most ATP is generated


-organelle with various specialized metabolic functions
-produces hydrogen peroxide as a by product then converts it to water


-prominent organelle in older cell plans
-functions include storage breakdown of waste products hydrolysis of macromolecules
-enlargement of vacuole is a major mechanism of the plant growth

central vacuole

-photosynthetic organelle
-converts energy of sunlight to chemical energy stored in sugar molecules


cytoplasmic channels through the cell walls that connect the cytoplasm of the adjacent cells


-outer layer that maintains cell shape and protect yourself from mechanical damage
-made of cellulose and other polysaccharides and protein

cell wall
