Which of the following are characteristics of living things?
Made of cells and composed of chemicals
Have hair, move and sleep
Use energy and respond to stimuli
Grow, develop and reproduce
The idea that living things can arise from nonliving things is called spontaneous generation instant generation spontaneous reproduction instant reproduction( spontaneous generation, instant generation, spontaneous reproduction, instant reproduction ).
Biogenesis Abiogenesis Spontaneous generation Biology( Biogenesis, Abiogenesis, Spontaneous generation, Biology ) is the observation that living things come only from other living things through reproduction.
Name four scientists that participated in the debate over spontaneous generation.
Leuuwenhoek, Hooke, Janssen, and Zeiss
Redi, Needham, Leeuwenhoek, and Pasteur
Redi, Hooke, Leeuwenhoek and Spallanzani
Redi, Needham, Spallanzani, and Pasteur
Redi's experiment was designed to prove that flies do not arise from decaying meat.
What ingredient did Needham, Spallanzani and Pasteur all use in their experiments to prove or disprove abiogenesis?
broth
chicken legs
human hair
unicorns
What basic needs do all living things have?
water
food
living space
love
stable internal conditions
Organisms that make their own food are called autotrophs trophies automobiles heterotrophs( autotrophs, trophies, automobiles, heterotrophs ).
Heterotrophs Autotrophs Trophies Automobiles( Heterotrophs, Autotrophs, Trophies, Automobiles ) are organisms that cannot make their own food.
Which of the following is an example of an autotroph?
bears
people
trees
bees
Which of the following is an example of a heterotroph?
Homeostasis Homogenous Monostasis Homeochrome( Homeostasis, Homogenous, Monostasis, Homeochrome ) is the maintenance of stable internal conditions.
The temperature that humans need to maintain homeostasis is 98.6 degrees F (37 degrees C).
How many kinds of organisms have scientists identified on Earth?
more than one thousand
more than one hundred thousand
more than one million
more than one billion
Classification Kingdom Order Specification Gentrification( Classification, Kingdom Order, Specification, Gentrification ) is the process scientists use to organize living things into groups based on similarities.
Why do scientists classify living things?
To make them easier to study
Because everything deserves to belong to a group
To make them smell better
So they don't accidentally lose them
The scientific study of how living things are classified is called taxonomy taxidermy tax collector taxi driver( taxonomy, taxidermy, tax collector, taxi driver ).
Binomial nomenclature...
was created by Carolus Linnaeus.
is a two-part scientific name.
uses both genus and species to name organisms.
uses Latin.
There are 9 levels of organism classification.
Choose the answer that lists the levels of classification from greatest to most specific.
domain, kingdom, phylum, class, order, family, genus, species
species, genus, family, order, class, phylum, kingdom, domain
domain, phylum, kingdom, class, family, order, species, genus
How many domains are used to classify living things?
2
What are the names of the three domains of living things?
Animals, Insects, and Plants
Larry, Curly, and Moe
Antibacteria, Archaic, and Eugene
Bacteria, Archaea, and Eukarya
Where can you find bacteria?
What do you call cells that don't have a nucleus?
Brainless
Prokaryotes
Protagonist
Where can you find organisms that belong to the domain Archaea, which like to live in the most extreme environments on Earth?
cow intestines
hot springs
salty water
your sister's hair
There are four kingdoms within the domain Eukarya. What are they?
Protists, Fungi, Plants, and Animals
Cats, dogs, hamsters, and guinea pigs
Albatross, Chickadee, Egret, and Gull
Mushroom, Conifer, Human, and Duck
Cells...
are named for "small rooms."
were discovered by Robert Hooke.
are the basic units of structure and function in living things.
were discovered in a thin slice of cork.
One square centimeter of your skin's surface contains more than 100,000 1,000 10,000 1,000,000( 100,000, 1,000, 10,000, 1,000,000 ) cells.
Name this object.
First compound microscope
Simple microscope
First telescope
Transmission Electron Microscope
Who invented this compound microscope, which used three lenses and an oil lamp for lighting, in 1660?
Zaccharias and Hans Janssen
Robert Hooke
Anton Von Leeuwenhoek
Ernst Abbe and Carl Zeiss
In 1674, Anton Von Leeuwenhoek created a simple microscope. What made it special?
It used one tiny lens crafted by his own hand.
He developed more than 500 lenses for it.
It magnified things 266x.
It showed objects in 4D.
Who were the first scientists to use the laws of physics and optical theory to build a compound microscope?
Robert Hooke and Anton Von Leeuwenhoek
Ernst Ruska and Carl Inventor
What did Anton Von Leeuwenhoek call the moving organisms he saw through his microscope?
little swimmers
fishies
animalcules
organimals
What three scientists are best known for developing the cell theory?
Mickey, Minnie, and Pluto
Schleiden, Schwann, and Virchow
Rodriguez, Falcao, and Valderrama
Moyer, Salazar, and Afanador
The cell theory states...
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
Cells like to party like it's 1999.
All cells arise from pre-existing, living cells, through biogenesis.
Identify the animal cell.
Identify the plant cell.
Organelles Cellulites Cellulitos Organitos( Organelles, Cellulites, Cellulitos, Organitos ) are the tiny structures inside a cell.
This provides support and protection in plant cells.
cell wall
cell membrane
cytoplasm
chloroplasts
This controls what substances come into and go out of a cell. It is called the "gatekeeper."
cystoplasm
This is the clear, gel-like fluid that keeps the organelles within a cell in place.
Cytoplasm
golgi bodies
vacuoles
This controls all the activities of the cell. It is nicknamed the "control center."
nucleus
mitochondria
endoplasmic reticulum (ER)
ribosomes
These are known as the "powerhouses" of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.
These passageways carry proteins and other materials from one part of the cell to another. Nicknamed the "transportation system."
endoplasmic reticulum
Ribosomes Mitochondria Cytoplasm Lysosomes( Ribosomes, Mitochondria, Cytoplasm, Lysosomes ) are the "factories" that produce protein within a cell.
This organelle receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell. Nicknamed the "packaging room."
Chloroplasts Cytoplasm Mitochondria Vacuoles( Chloroplasts, Cytoplasm, Mitochondria, Vacuoles ) are only found in plants. They capture energy from sunlight and use it to produce food for the cell.
These are the storage areas of the cell. Nicknamed the "warehouse."
lysosomes
These are small, round structures containing chemicals that break down certain material in the cell. Nicknamed the "clean up crew" or the "garbage disposal."
