What is the meaning of the word "eukaryote"?
At one time, all prokaryotes were lumped into "Kingdom Monera."
We now know that there are two distinct lineages of

Overview and fertilization
Four Stages of Growth and Development
Gametogenesis: formation of sperm and eggs

An Introduction to Botany Why should we care about PLANTS?
Without plants, most of life on earth as we know it would not exist.
Plants comprise about 98% of the earth's biomass!
Plants are primarily responsible for creating our oxygen-rich atmosphere via
47.2: 47.2: Animal DevelopmentPart 2
A succession of rapid cell divisions after fertilization.
Think of it as having three stages:
1. Beginning: zygote (a single cellthe fertilized egg)
2. Middle: morula (a solid ball of cells)
3. Ending: blastul

History of Classification:
4000 BC Aristotle
Creates first written classification scheme

The Wonderful World of Fungi
What is a Fungus?
Along with bacteria, these are the most important DECOMPOSERS in the biosphere. They convert dead, organic
matter into its inorganic components.
mycelium - the entire body of the fungus

Basic Characteristics of Animals
Multicellular chemoheterotrophic eukaryotes
They must take organic molecules into their body through ingestion (eating).
Lack cell walls
No true organs; Asymmetrical symmetry; Spicules- cells that provide
support and structure; Osculum- opening at the top of the sponge

Microbial Metabolism Chapter 5
sum of all chemical reactions within a living organism
Can be divided into two classes:
1. reactions requiring energy = anabolic
2. reactions generating energy = catabolic

Chemical Building Blocks & Chemical Bonds
Matter composed of one type of atom =
(e.g. Carbon [C], nitrogen [N], oxygen [O], sodium [Na]).
Two or more atoms combine to form:
Either same type of atom
Or different (e.g
