Scientists call the first part of an organism's name the ____________.
The second part of an organism's scientific name is called the __________.
What do scientists call the organisms that use the sun's energy to make their own food?
autotrophs (auto means "self")
What is the most abundant chemical in cells?
The cells of a _______________ lack a nucleus.
prokaryote (Pro sounds like NO)
Organism's with cells that contain a nucleus are called _________________.
eukaryotes (eu sounds like DO)
An action or change in an organism's behavior or environment that occurs as a result of a stimulus is called a _____________.
A change in an organism's surroundings that causes an organism to react is called a ________________.
What is the main energy source for cells?
______________is the process of change that occurs during an organism's life to produce a more complex organism.
_______is the process of getting larger.
An organism's ability to maintain stable internal conditions is called __________________.
(Hint: maintain means to keep the same)
Organisms that cannot make their own food are called___________________.
A Swedish scientist, Carolus Linnaeus, devised a two-part naming system for organisms called__________________.
An organism can successfully reproduce at which level?
What are the six characteristics that all living things share?
(Hint: John McNeil's silly cell phone story)
- 1.cellular organization
- 2.contain similar chemicals
- 3.use energy
- 4.respond to their surroundings
- 5.grow and develop
What are the four things that all organisms need to stay alive?
- 1.energy (same as food)
- 3.living space
- 4.stable internal conditions
- (energy water looks so scrumptious)
What are the seven levels of classification after the DOMAIN level?
- (After Domain level)
- King Philip came over for ginger snaps.
_____________________designed a controlled experiment to show that flies do not arise from decaying meat.
The scientific study of placing organism's into groups based on shared characteristics is ________________.
The idea that life could spring from nonliving matter is called_____________.
Scientists call the process by which organisms gradually change over a long period of time is called ______________.
An organism made up of many cells is called _____________________.
An organism that is made up of a single cell is called __________________.
Your first teeth falling out and being replaced by permanent teeth and male facial hair growth are both examples of __________________.
When an organism eats vegetables and salad they are acting like a/an________.
a. an autotroph
b. a heterotroph
c. a stimulus
Who was the scientist who demonstrated that new bacteria appeared in broth only when they were produced by existing bacteria? (Life comes from life)
(1)What is the difference between autotrophs and heterotrophs?
(2)Give an example of each.
Autotrophs are self feeders. Using the sun's energy they make their own food. Plants are autotrophs.
Heterotrophs cannot make their own food. They rely on the energy they consume from autotrophs and heterotrophs. All animals are examples of heterotrophs because they eat plants and animals to get the energy they need to survive.
What are the 3 domains of life called?
(Remember: The domains were added because of the advancement of technology. Modern technology has allowed scientists to see many more differences among cells so added the domains)
- 1. bacteria
- 2. archaea
- 3. eukarya
What are the 4 kingdoms in the Eukarya domain?
What kingdom is bread mold found in?
What are the 3 conditions that scientists believe are best for mold to grow?
What is the difference between a prokaryote and a eukaryote?
- (Pro sounds like NO/Eu sounds like DO)
- Prokaryotes lack a nucleus (Do not have)
- Eukaryotes contain a nucleus (have)
An organism's scientific name consists of two parts. The first and second parts are the __________ and __________.
Genus and species
- (First name, or genus, is always capitalized/the second name, or species, is not capitalized
- Example: Felis domesticus)
