Anatomy Cells

Front 1

Cell membrane

Back 1

Composed of protein and lipid molecules. Maintains integrity of the cell, controlls passage of material into and out of cell, provides for signal transduction

Front 2

Ribosomes

Back 2

Composed of protein and rna molecules. Synthasize proteins

Front 3

Endoplasmic reticulum

Back 3

Complex of connected membrane sacs, canals, and vesicles. Transports materials within the cell, provides attatchment for ribosomes, and synthasizes lipids

Front 4

Vesicles

Back 4

Membranous sac. Contains substance that recently entered the cell, store and transport newly synthasized molecules

Front 5

Golgi apparatus

Back 5

group of flattened membranous sacs. Packages and notifies protein molecules for transport and secretion

Front 6

Mitochondria

Back 6

Release energy from food molecules and convert the enery into a usable form called ATP

Front 7

Lysosomes

Back 7

Membranous sac. Contain enzymes capable of digesting worn cellular parts or substances that enter the cell

Front 8

Peroxisomes

Back 8

Membranous sac. Contain enzymes called peroxidases, important in the breakdown of many organic molecules

Front 9

Centresome

Back 9

Nonmembranous structure composed of 2 rod like centrioles. Helps distribute chromosomes to new cells during cell divosion, initiates formation of cilia

Front 10

Cilia

Back 10

Motile projections attatched to basil bodies beneath the cell membrane. Some cilia propel fluids over cell surface; others are sensory

Front 11

Flagellum

Back 11

Projection attatched to a basil body beneath the cell membrane. Enables sperm cell to move

Front 12

Microfilaments and microtubules

Back 12

Thin rods and tubules. Support cytoplasm, help move substances and organelles within the cytoplasym

Front 13

Nuclear envelope

Back 13

Selectively permeable double membrane that seperates the nuclear contents from the cytoplasym. Maintains the integrity of the nucleus, controls the passage of materials between the nucleus and cytoplasym

Front 14

Chromatin

Back 14

Fibers composed of protein and DNA molecules. Carries information for synthasizing proteins

Front 15

Nucleoulus

Back 15

Dense nonmembranous body composed of protein and RNA molecules. Site of ribosome formation
