Cells and Organelles
Much of what you will need to know applies to the structure of eukaryotic cells. They are characterised by having membrane-bound organelles.

Organelle
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body.

What Is Organic Chemistry?
What do you think of when you think of when you hear the word organic? Do you think of the baby carrots that you saw in the grocery store the other day or do you think of something entirely different?

Organic molecules are those that: 1) formed by the actions of living things; and/or 2) have a carbon backbone. Methane (CH4) is an example of this. If we remove the H from one of the methane units below, and begin linking them up, while removing other H units, we begin to form an organic molecule.

Well, the organic spores, I'm not really familiar with how they use those, because they don't use them a lot in this particular area because of the lower incidence of corn borer.

The plant body is divided into several organs: roots, stems, and leaves. The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy.

UNC-69 and UNC-76 regulate presynaptic organization cooperatively
We showed above that UNC-69 is required for localization of synaptic vesicles in axons. Does UNC-76 also have a role in this process, and if so, does UNC-76 control presynaptic organization together with UNC-69?

Organelles of the Cell
Eukaryotic cells (all organisms except bacteria and archaea (prokaryotes)) have complex organelles which are surrouned by their own membrane (similar to the cell membrane).

Organisms depend on the cohesion of water molecules.
The hydrogen bonds joining water molecules are weak, about 1/20 as strong as covalent bonds.
They form, break, and reform with great frequency. Each hydrogen bond lasts only a few trillionths of a second.

centimorgan (cM) The metric used to describe linkage distances. A centimorgan is the distance between two genes that will recombine with a frequency of exactly one percent. This term is named afer Thomas Hunt Morgan, who first conceptualized linkage while working with Drosophila.

Centimorgan. Metric used to describe linkage distances. 1 cM = 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation. In humans, 1 cM=1,000,000 bp. See linkage map.

centimorgan
The unit of linkage that refers to the distance between two gene loci determined by the frequency with which recombination occurs between them. Two loci are said to be one centimorgan (cM) apart if recombination is observed between them in 1% of meioses.

Moving Organisms
Beyond the role they play in internal cell movement, microtubules also work together to form larger structures that work on the outside of the cells. They can combine in very specific arrangements to form cilia and flagella.

Centimorgan (cM)
A unit of measure of recombination frequency. One centimorgan is equal to a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation.

Organisms get oxygen from their environment in a variety of ways. Many land animals breath oxygen directly from the air, while ocean bearing animals often use the oxygen dissolved in the water to survive. No matter how they get it, oxygen is an important need for almost all life forms.

Organisms have short sequences of bases which are repeated many times. These are called satellite DNA. These repeated sequences vary in length from person to person. The DNA is copied using PCRand then cut up into small fragments using restriction enzymes.

Organisms are not passive targets of their environment. Each species modifies its own environment. At the least, organisms remove nutrients from and add waste to their surroundings. Often, waste products benefit other species. Animal dung is fertilizer for plants.

organ A structure composed of different tissues, such as root, stem, leaf, or reproductive (e.g., flower) parts.

All organisms begin as a single cell, but multicellular organisms have programming to produce cells that have considerably different characteristics, even though the DNA is presumably identical. Kim, et al.
