Cells
• Cell membrane- keeps all the cell structures in the cell and prevents substances from entering

Cells
• Cytoplasm- all structures outside the cell nucleus
• Mitochondria- responsible for catabolism- breaking down molecules and releasing energy
Mitochondria
From Wikipedia.com
Cells
• Endoplasmic Reticulum- responsible for anabolism- making chemicals and structures from proteins– Smooth
• Produces lipids, metabolism of carbohydrates, and detoxification of drugs and poisons
– Rough• manufactures and transports proteins destined
for membranes and secretion

Cell Activity
• Catabolism breaking down molecules and releasing energy
• Anabolism making chemicals and structures from proteins
• Metabolism is a combination of catabolism and anabolism
Cell Specialization
National Institute of Health: An Owner’s Guide to the Cell
Cell Specialization
• Muscle cells-• Epithelial cells- provides covering
layer of all body surfaces and linings of internal organs
• Nerve cells-neuron• Fat cells- lipid

Genetics
• Chromosomes- contain all genetic material that is passed down to daughter cells
• Karyotype- a picture of the chromosomes from a cell nucleus– Sperm and eggs contain ½ the genetic material of regular
cells– Each chromosome is made up of genes– Genes are made of DNA– The DNA sequences are the directions for all traits of an
organism
Body Organization
• Cells• Tissues- groups of similar cells working
together• Organs- internal organs are called viscera
– Comprised of several types of tissues
• Systems- groups of organs working together to perform complex functions
DNA
Different levels of DNA condensation. (1) Single DNA strand. (2) Chromatin strand (DNA with histones). (3) Chromatinduring interphase with centromere. (4) Condensed chromatin during prophase. (Two copies of the DNA molecule are
now present) (5) Chromosome during metaphase.
