Cell Organelles

Front 1

Cell membrane

Back 1

Compocition: Lipid bylayer, containing phospholipids, steroids, and proteins.

Function: Provides isolation, protection, sensitivity and support; controls entrance and exit of materials.

Front 2

Cytosol

Back 2

Composition: Fluid component of cytoplasm.

Function: distribute materials by diffusion.

Front 3

Cytoskeleton

Back 3

Composition: Proteins organized in fine filaments or slender tubes.

Function: Provides strength and support; enables movement movement of cellular structures and materials.

Front 4

Microtubbuials

Back 4

microtubules and micrfilliamnts make up the cytoskeleton.

Front 5

Ribosomes

Back 5

ribosomes are found attached to the RER. Free ribosomes are scattered in the cytoplasm. Ribosomes Synthesize protein.

Front 6

globi Apparatus

Back 6

Sacks of flattened membranes containing chambers. it stores, alters and packages secretory products; formes lysomes

Front 7

Lysomes

Back 7

vesecles containing powerful digestive enzymes. They remove damaged organelles or pathogens within the cell.

Front 8

mitochondria

Back 8

Double membrane, with inner folds enclosing important metabolic enzymes. Produces 95% of the ATP required by the cell.

Front 9

Centrioles

Back 9

Two centrioles, at right angles; each composed of microtubules. they are essential for movement of chromosomes during cell division.

Front 10

Nucleus

Back 10

Contains DNA, nucleotides, enzymes and proteins; surrounded by a double membrane. Controls metabolism; stores and processes genetic information; controls protein synthesis.

Front 11

chromatin and chromosomes

Back 11

Each are found within the nucleolus of the cell. Chromatin is DNA that is loosley spread out. Chromosomes are tightly wound DNA that is ready for cell mitosis.

Front 12

Nucleoli

Back 12

Dense region in nucleoplasm containing DNA and RNA. Synthesizes RNA and assembles ribosomal subunits.

Front 13

Cilla

Back 13

Membrane extensions containing microtubules. it moves material over the cells surface

Front 14

SER

Back 14

Smooth endoplasmic riticulum: A network of membranous channels extending throught the cytoplasm. It synthesizes lipids and carcohydrates.

Front 15

RER

Back 15

Rough endoplasmic riticulum: A network of membranous channels extending throught the cytoplasm that has ribosomes attached to its membranes.It synthesizes secretory products; provides intracellular storage and transport. Packages newly synthesized proteins.

Front 16

Flagella

Back 16

A threadlike appendage, especially a whiplike extension of certain cells or organisms that functions as an organ of locomotion.

Front 17

Microvilli

Back 17

Membrane extensions containing microfilaments.Increase surface aera to facilitate absorbtion of extracellular materials.
