Science Test TUESDAY!!!
Before the descovery of orgainisms like Euglena, all organsims were classified as either what?
plants or animals
Scientists classify organisms based on their what?
WHich characteristic is not true for organisms of the genus Euglena?
A green color and the ability to make food through photosynthesis might make some people think that members of the genus Euglena are what?
Which is a characteristic that animals and members of the genus Euglena posses but plants do not?
ability to move by themselves
Do you think there will always be six kingdoms used for classifying organisms?
No, as time goes on we will find new organisms and have to make new kingdoms that they fit under
Bacteria are what, or organisms that lack nuclei?
Scientis added the kingdom what, creating a classification for organisms that had characteristics of both plants and animals?
Many scientists divide bacteria into two kingdoms: what?
Archaebacteria and Eubacteria
Some of these live inside humans.
One of these causes pneumonia.
These live in places where most other organisms could not live.

Plants can be found growing on what and in what that can penetrate.
1. land 2. water
Explain why the food that plants make is important not only to the plants themselves but to other organisms as well?
If a surtain organism eats something else, and that something else dies, than that surtain organism will also die and that cycle keeps on going
Plants provide nutrients for other organisms. What is another way that trees and other flowering plants are used by animals?
Some animals make their homes in trees

Eukaryotic(true nucleus), Multicellular, Cell membrane(no cell wall), Obtains nutrients from other organisms, Have the ability to move, either a herbivore, ominvore, or a carnivore
Members of kingdom Animalia have specialized sence organs that allow them to do what?
respond to their environment
Members of kingdom Animalia are commonly called what?
Explain how animals need plants?
Some animals are ominvores, which the animal only eats plants, so they would need the plants for food to survive
Explain how animals depend on bacteria and fungi?
Fungi and bacteria are depended on by the animals to recycle the nutrients found in dead organisms
The kingdom Animalia includes some very simple members, such as what, that do not have sence organs and cannot move?
The division of organisms into groups, or classes, based on specific characteristics
Putting plants and animals into orderly groups based on similar characteristics is called what?
Classifying living things help human beings because why?

lions and house cats
Early scientists divided organisms into two groups. What were they?
animals and plants
What swedish botanist and physician created the first organized, modern taxonomy?
How many levels of classification do scientists use today?
Why are the platypus, brown bear, lion, and house cat thought to be related to each other?
Because they all contain hair, or mammary glands
What characteristics do the bear lion and house cat have that the platypus doesnt?

The singular form of the word genera is what?
In order from largest to smallest, what are the seven levels of classification
Kingdom, Phylum, Class, Order, Family, Genus, Species
No matter how many common names an organism might have, it only has one what?
How was the naming of organisms different before Carolus Linnaeus, and how was the system difficult for scientists?
Scientists used 12 words to describe organisms. Hard to work with because the organism could have more than one name
Who simplified the naming of living things by giving each species a 2-part scientific name?
IN the scientific name for the Asian elephant, Elephas maximus. the word Elephas indicates the animals what?
All genus names begin with a what?
All species names begin with a what?
