Cyanobacteria are organisms commonly found in streams and ponds as chains of cells. A portion of a chain of cyanobacteria cells is shown in the diagram below. The major parts of a cyanobacteria cell are labeled.
Is cyanobacteria a prokaryotic or eukaryotic cell? How can you tell by looking at the diagram?

Look at the picture of the plant cell. Identify two structures that are not labeled in the plant cell AND describe the functions of the two organelles you identified.
What is represented by the small dots found in each of the bacteria cells?
free-floating DNA
ribosomes
cell membrane
flagellum
What might be the purpose of this the flagellum (the tail-like structure)?
storing genetic information
making protein
movement
eating
State two structures that are present in plant cells and not animal cells.
plant cells have mitochondria and ribosomes while animal cells do not
plant cells have a nucleus and animals cells do not
plant cells have chloroplast and a cell wall while animal cells do not
plant cells have cytoplasm and a plasam membrane unlike animal cells
Muscle cells are important to motion in the body. They form muscle tissue which contracts to move substances within the body or to help the body move in the environment. Why might muscle cells have more mitochondria than other cells.
have more mitochondria because they need more energy
have more mitochondria because they have more genetic material to store
have more mitochondria because they need to store water
have more mitochondria so they can make more proteins
A student makes the following statement: "
"Plant cells don't need mitochondria. They have organelles that help them make their own food and so they do not need mitochondria"
Is this a true statement?
No
Yes
A cell from an organism has a nucleus, mitochondria, a cell wall, and chloroplast. The organism is most likely classified as which of the following?
animal
bacterium
prokaryote
plant
Each of the illustrations shows either a prokaryotic cell or a eukaryotic cell. Each cell is numbered. Which two cells should be classified as prokaryotic cells?
1 and 2
1 and 3
3 and 4
2 and 4

Both cyanobacteria and plant cells have golgi
Both cyanobacteria and plant cells have a nucleus
Both cyanobacteria and plant cells have mitochondria
Both cyanobacteria and plant cells have a cell wall
