Cells And What They're Made Of

Front 1

Cytomembrane system

Back 1

1. group of related organelles in which lipids are assembled and new polypeptide chains are modified
2. products are sorted and shipped to various destinations

Front 2

Rough ER

Back 2

1. Arranged into flattened sacs
2. ribosomes on surface give it a rough appearance
3. some polypeptide chains enter through rough ER and are modified
4. cells that specialize in secreting proteins have lots of Rough ER

Front 3

Smooth ER

Back 3

1. A series of interconnected tubules
2. no ribosomes on surface
3. lipids assembled inside tubules
4. smoot ER of liver enactivates wastes and drugs
5. sarcoplasmic reticulum of muscle is a specialized form

Front 4

Golgi bodies

Back 4

put finishing touches on proteins and lipids that arrive from ER
2. package finished material for shipment to final destinations
a. material arrives and leaves in vesciles

Front 5

Vesicles

Back 5

1. membranous sacs that move through the cytoplasm
a. lysosomes
b. peroxisomes

Front 6

Mitochondria

Back 6

(both)---located in cytoplasm
1. important for energy (ATP) production in the cell
2. the powerhouse of the cell
3. important in cellular respiration

Front 7

Chloroplasts

Back 7

plant only---against edge of cytoplasm
1. site of photosynthesis in cell

Front 8

Cytoskeleton

Back 8

both---cytoplasm
1. provides shape and internal organization for the cell

Front 9

Microtubules (tube--hollow)
(element of cytockeleton)

Back 9

1. largest elements
a. composed of protien tubulin
2. arise from microtubule organizing centers (MTOCs)
3. polar and dynamic
a. involved in shape, motility, and cell division

Front 10

Microfilaments(fil--filled)
(element of cytoskeleton)

Back 10

1. thinnest cytockeletal elements
a. composed of protein actin
2. polar and dynamic
a. take part in movement formation and maintenances of cell shape

Front 11

Accessory proteins

Back 11

1. attach to tubulin and actin
2. motor proteins(movement)
3. crosslinking proteins (holds together)

Front 12

Flagella & Cilia

Back 12

1. structures for cell motility
2. 9+2 internal structure

Front 13

Cell Wall

Back 13

plant only---cytoplasm
1. rigid shell gives shape to cell
2. provides tugor pressure when cell fills with water

Front 14

Cell to cell junctions

Back 14

1. plants
a. plasmodesmata
2. animals
a. tight junctions
b. adhering junctions
c. gap junctions

Front 15

animal cell junctions

Back 15

1. archaebacteria and Eubacteria
a. DNA is NOTNOTNOT enclosed in nuculeus
b. generally the smallest simplest cells
c. no organelles
