Human A And P Cell

Front 1

Plasma membrane

Back 1

-later if lipids and proteins in constantly changing fluid mosaic

-separates intracrllular fluid from ecf

Front 2

Mitochondria

Back 2

-double membrane with shelf like crustal

-Site of ATP synthesis; powerhouse of the

cell., contain dna and rna and are able to on reproduce on their own (such as needed in atp production)

Front 3

Ribosomes

Back 3

-granules containing rRNA and protein

The site of protein synthesis. Located in cytoplasm and on rough er

Front 4

Rough endoplasmic reticulum

Back 4

-surface stubbed with ribosomes

-manufactures secreted proteins and makes the components of the cell

Front 5

Smooth endoplasmic reticulum

Back 5

-tubules arranged in a looping network

-breaks down glycogen, detoxify drugs and carcinogens, in testis makes testosterone, in intestines site of absorption synthesis and transport of fats, and in skeletal and cardiac muscles release of calcium the triggers contraction

Front 6

Golgi apparatus

Back 6

-stacked and flattened membranous sacs

-Packages and ships, functions in modification, concentration and packaging proteins and lipids

Front 7

Lysosomes

Back 7

-spherical membranous bags containing digestive enzymes

-package of strong acids and enzymes that can destroy whole cell, digest bacteria virus and toxins, suicide bags of the cells

Front 8

Peroxisomes

Back 8

-membranous sacs containing powerful oxidases and catalases

- detoxifies harmful substances and neutralizes free radicals

Front 9

Peroxisomes

Back 9

-membranous sacs containing powerful oxidases and catalases

- detoxifies harmful substances and neutralizes free radicals

Front 10

Cytoskeleton

Back 10

Elaborate series of rods throughout cytosol

Front 11

Microfilament

Back 11

-actin strands attached to cytoplasmic side of plasma membrane

- function in bracing and strengthening cell, helps cell change shape to move and function in endocytosis and exocytosis

Front 12

Intermediate filament

Back 12

-tough insoluble, rope-like, protein fibers

-most stable,most permanent, resists pulling forces on cell, and attaches to desmosomes

Front 13

Microtubules

Back 13

-dynamic hollow tubes that radiate from centrosome

-they determine overall shape of cell, used to distribute organelles

Front 14

Centrioles

Back 14

-cell center near nucleus

-generates microtubules and mitotic spindle fibers during mitosis

Front 15

Cytoplasm

Back 15

Intercellular fluid packed with organelles

Front 16

Nuclueus

Back 16

-largest organelle, contains fluid and is surrounded by nuclear envelope

-control center of cell, transmits genetic information, provides instructions for protein synthesis

Front 17

Nuclear envelope

Back 17

- double membrane structure pierced by pores

-separates nucleoplasm from cytoplasm, regulates transport of large molecules into and out of nucleus

Front 18

Nucleolus

Back 18

- dense spherical body composed of rna and proteins

-site of ribosome submit manufacture and r-rna synthesis

Front 19

Chromatin

Back 19

-fundamental units are nucleosomes

-Made up of dna, histone proteins,rna

Arranged in units called nucleosomes

Condense into chromosomes

Front 20

Mitochondria

Back 20

Powerhouse of the cell, double membrane structure that contains its own dna and rna and can reproduce to increase atp production
