Mitosis: The Natural Cloning Process

All living organisms grow and reproduce. Eukaryotic organisms, which include you and I, accomplish this through a process called mitosis. During mitosis, a cell clones itself allowing its DNA to be replicated and distributed equally among two cells.

Know Your Plant Parts

Flowering plants, also called angiosperms, are the most numerous of all the divisions in the Plant Kingdom.

The parts of a flowering plant are characterized by two basic systems: a root system and a shoot system.

These two systems are connected by vascular tissue that runs from the root through the shoot.

The root system enables flowering plants to obtain water and nutrients from the soil. The shoot system allows plants to reproduce and to obtain food through photosynthesis.

Mammal Species

Saturday July 5, 2008
Have you ever thought about what makes mammal species different from other vertebrates?

If not, I'm sure that you have noticed the differences between a crocodile (which belongs to the vertebrate class reptilia) and an elephant.

Being a mammal myself, I have always found this particular class of vertebrates very interesting.

Mammals have certain characteristics that differentiate them from other vertebrates.

Some of these characteristics include hair or fur, the ability to maintain a constant body temperature, and the production of milk.

To learn more about the characteristics that differentiate mammal species from other vertebrates, see Mammal Species.
