Front 1

nuclear envelope

Back 1

porous double membrane that separates nuclear contents from cytoplasm
function- maintains wholeness if the nucleus and controls passage of materials between nucleus and cytoplasm

Front 2

chromatin

Back 2

fibers composed of protein and DNA molecules
function- contains genetic information for protein synthesis

Front 3

cilia & flagella

Back 3

hairlike projections attached to basal bodies beneath cell membrane
function- propel fluids over cellular surface and enable certain cells to move

Front 4

lysosomes

Back 4

membrane sacs
function- contain enzymes for intracellular digestion

Front 5

cell membrane

Back 5

membrane composed mainly of protein and lipid molecules
function- maintains wholeness of cell and controls passage of materials in and out of the cells

Front 6

vesicles

Back 6

membrane sacs
Function: contain various substances after abtry into the cell

Front 7

endoplasmic reticulum

Back 7

network of interconnected membranes consisting of sacs and canals
function: transports materials within the cell

Front 8

nucleus

Back 8

surrounded by the nuclear envelope

Front 9

microfilaments and microtubules

Back 9

thin rods and tubules
function: provide support to cytoplasm and help move objects within the cytoplasm

Front 10

nucleolus

Back 10

dense membranous body composed of protein and RNA
Function: contains materials to form ribosomes

Front 11

Golgi body

Back 11

group of flattened membranous sacs
function: packages protein molecules for secretion

Hint 11

aka golgi apparatus

Front 12

ribosomes

Back 12

particles composed of protein and RNA
function: bodies where proteins get synthesized

Front 13

centrosomes

Back 13

non membranous structure composed of two rod like centrioles
function: helps distribute chromosomes to daughter cells during cell reproduction

Front 14

mitochondria

Back 14

membranous sacs with inner partitions
function: site where energy released from food molecules
