wrap-up
history of classification
The first scientific classification system for living things started all started Aristotle. He broke up living things by plants and animals. He put the plants in to herbs, shrubs, and trees. He put the animals in water, land, and air.
modern classification
The current classification system used today are
- Plants
- Animals
- Protists
- Fungi
- Archaebacteria
- Eubacteria
archeabacteria and eubacteria
They're either archaebacteria or eubacteria. They are all unicellular prokaryotic organisms and can be found in almost every environment on earth. They have a cell wall and their genes are found in a circular chromosome rather than paired chromosomes. The only way to see them is if they are under a microscope or if they are growing in vast colonies.
protist
Protists are unicellular or multicellular organisms that are eukaryotic. There are very few multicellular protists though. There are many different types of protists out there. There are plant type, animal types, and fungi type protists.
fungi
Fungi is a type of organisms that used to be classified as plants. Scientists thought that fungi was a type of plant because they thought that fungi could produce their own food and because they grow in soil or decaying logs
plants
Plants are eukaryotic and one the most important organism to our environment because they are at the base of the food chain and provide the most energy to other organisms.
ANIMALS
Animals are multi-cellular organisms that are pretty much everywhere.They are one of the most diverse kingdoms out there and range from things that dwell at the bottom of the sea to organism that can fly.
transport
Basically all cells in all organisms work the same. They go through active transport or passive transport. Passive transport lets things get into the cells without any energy needed.
excretion
Protist's excretion system is basically only involves them getting rid of their waste by using a process known as diffusion.
communication
All of the function of a body are all really controlled by the nervous system and endocrine system. This applies to all animal like the worms, insects, amphibians, and mammals.
resperation
Every single organism goes through a process of respiration. Respiration gives the cells energy to perform their functions.
nutrition
Annelids, protists, insects, amphibians, and mammals all get their nutrients from eating other organisms. Plants on the other hand don't. They break the food down all in a similar process and excrete their waste. Nutrients are required for the body to perform their every day functions.
reproduction
All organisms reproduce mostly the same. They can reproduce asexually and sexually. Even though they are different organisms and they go through different processes, all organisms can produce sexually, which involves a male fertilizing a females eggs with its semen.
growth and development
All organisms sort of all grow similarly. When either an offspring is produced asexually or sexually, they grow and develop nearly the same. They start off as an embryo or a seed and grow into babies or saplings
