Cell Theory
These are considered the basic unit of sttucture and function in living things
What are Cells?
Organisms that make their own food are called this.
What are autotrophs?
Cells with a nucleus are called these.
What are eukaryotic cells?
Plants use this process to make food.
What is photosynthesis?
Differences in traits among members of the same species are called these.
What are variations?
This scientist first observed cork cells using a microscope.
Who is Robert Hooke?
Organisms that must consume other organisms for energy are called this.
What are heterotrophs?
Cells without a nucleus are called these?
What are prokaryotic cells?
A mushroom is this type of organism because it cannot make it own food.
What is a heterotroph?
A rabbit with white fur surviving in snowy areas ia an example of this?
What is advantageous variation?
What is a helpful trait?
Cell theory states that all cells come from these.
What are pre-existing cells?
This term describes an organism make of one cell.
What is unicellular?
This organelle separates eukaryotes from prokaryotes.
What is the nucleus?
This is the original energy source for most ecosystems.
What is the Sun?
Variations can help populations survive when these change.
What are environments?
Scientists Schleiden and Schwann concluded that all plants and animals are made of these.
What are cells?
Humans, dogs, and trees are examples of this type of organism organization.
What is multicellular?
Plants and animals are examples of these types of organisms.
What are eukaryotes?
Organisms that break down dead organisms are called these.
What are decomposers?
Traits that make survival harder.
What are disadvantageous traits?
This part of the cell theory explains that cells carry out life functions.
What is "Cells are the basic unit of structure and function"?
Bacteria are usually classified as these two characteristics.
What are prokaryotic and unicellular?
True or False: All prokaryotes are multicellular.
What is false?
This type of organism can make its own food and is usually the producer in a food chain.
What is an autotroph?
This causes variations in populations.
What are differences in inherited traits?
