What is the difference between unicellular organisms and multicellular organisms?
Unicellular is made up of 1 cell and multicellular organisms are made up of more than 1 cell (usually many).
100
What is the organelle that releases energy from sugars and is considered to be the cell's "powerhouse"?
Mitochondria
100
What is an advantage of a light microscope?
You can use it to observe live specimens.
100
Put these organizational levels in the correct order, from smallest to largest. organism, cell, organ system, tissue, organ
cell, tissue, organ, organ system organism

What does the cell wall do?
It is the tough outer covering that lies just outside the cell membrane in a plant cell.
200
Give an example of a unicellular organism and an example of a multicellular organism.
Various. Examples: Unicellular (Paramecium, Euglena, etc.); Multicellular (dog, tree, human, etc.)
200
What is the organelle that encloses and protects the entire cell? It separates the inside from the outside.
Cell membrane
200
What is a disadvantage of a light microscope?
It can't be used to see very small organisms/details of organisms.
200
What is an organ?
Different tissues working together to perform a particular function.
200
What is the word used for any part of a cell that's enclosed by a membrane?
organelle
300
How did the microscope change human understanding of life?
It led to the discovery of cells since most are too small to see without it.
300
What is the gelatin-like material that houses organelles in a cell?
Cytoplasm
300
What is the advantage of an electron microscope?
It can be used to magnify objects up to a million times.
300
What is tissue?
It's a group of similar cells that are organized to do a specific job.
300
What is the organelle that contains genetic material and tells the cell what to do?
The nucleus
400
What are 3 things every organism needs to live?
1) Energy 2) Raw materials 3) Living space
400
What is the function of chloroplasts?
They use energy from sunlight to make sugar.
400
What is a disadvantage of using an electron microscope?
The specimen has to be dead. (It is either coated in gold or it is sliced.)
400
What is specialization?
When specific cells perform specific functions/jobs. They are organized in a way to be able to do this.
400
What organelle is found in animal cells but NOT plant cells?
lysosomes
500
What are the 4 characteristics common to all living things?
1) Organization 2) Develop and grow 3) Respond to its environment 4) Reproduce
500
What is the function of the central vacuole?
It stores water and other materials in plant cells.
500
What is the main difference between a prokaryotic cell and eukaryotic cell?
A eukaryotic cell has a nucleus and a prokaryotic cell does not have one. Prokaryotic - genetic material is in the cytoplasm; usually unicellular Eukaryotic - genetic material is stored in the nucleus; usually multicellular
500
What are the 3 domains of organisms? Which of these have cells that contain nucleus?
1) Bacteria 2) Archaea 3) Eukarya - contains a nucleus
500
What are the 3 organelles that are found in plant cells but NOT animal cells?
1) cell wall 2) chloroplast 3) central vacuole
