Front Back
-region where the cells microtubules are initiated
-contains a pair of centrioles
centrosome
-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
nucleolus
-material consisting of DNA and proteins
-visible in a dividing cell as individual condensed chromosomes
chromatin
membrane enclosing the cell
plasma membrane
-complexes that make proteins
-free in cytosol or bound to rough ER or nuclear envelope
ribosomes
organelle active in synthesis modification sorting and secretion of cell products
Golgi apparatus
digestive organelles where micro molecules are hydrolyzed
lysosome
organelle where cellular respiration occurs and most ATP is generated
mitochondria
-organelle with various specialized metabolic functions
-produces hydrogen peroxide as a by product then converts it to water
peroxisome
-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
chloroplast
cytoplasmic channels through the cell walls that connect the cytoplasm of the adjacent cells
plasmodesmata
-outer layer that maintains cell shape and protect yourself from mechanical damage
-made of cellulose and other polysaccharides and protein
cell wall
