The Basic Unit of Life - Biology Lab
What is the shape of an onion cell?
A circle
Are blood cells from a producer or a consumer? Explain.
A consumer because animals have blood cells, and they are incapable of producing their own energy. They are the consumers of producers.
Is duckweed a plant or an animal? Explain.
A plant because it is a producer and a cell wall is present (animal cells do not have cell walls).
Who is Robert Hooke?
An english scientist who, in 1665, reported an interesting observation while looking through his microscope at cork.
Are cheek cells produced by plants or animals?
Animals
Describe the location of the cell's cytoplasm.
Area in the cell, outside the nucleus.
What is the function of chloroplasts?
Captures the sun's energy and converts it into chemical energy by a process called photosynthesis.
What cell part name is used to describe the outer edge of a frog blood cell?
Cell Membrane.
What specific cell part is all that remains of the cell?
Cell Wall
What specific part was all that was left of the cork?
Cell Wall
What do fungi have that most consumers don't have?
Cell Wall.
What were the honeycomb units at which Hooke was looking at?
Cells (cork)
What chemical makes up the cell wall?
Cellulose
What is the shape of the frog blood cells?
Circular
Describe the shape of a cheek cell
Circular (with indents)
What is the shape of the duckweed cells?
Circular.
What are the small units that can be seen under high power called?
Cork Cells
What is the color of chloroplasts?
Green
Where do chloroplasts lie?
In the cytoplasm?
Where does the nucleus lie?
In the nuclear envelope.
Where is the nucleolus found?
In the nucleus.
What is the function of the nucleus?
It contains and protects the cell's genetic information in the form of DNA.
What is the function of the cell membrane?
It is a thin, flexible layer that regulates what enters and leaves the cell.
What is the function of the cell's Nucleolus?
It is the "Communication Center" of the cell and the assembly of ribosomes begin here.
What is the appearance of the cytoplasm?
Jelly like portion of the cell.
Are cork cells alive?
No
Do animals have cell walls?
No
Is the cell wall present in the Cheek Cell?
No, animals do not have cell walls.
Are chloroplasts present in consumer cells?
No, because consumers rely on producers for their energy intake, like green plants (Chloroplasts are only present in plant cells because of photosynthesis.)
Can a cell wall be seen in frog blood cells?
No, it does not contain one.
What are things found in a plant cell?
Nucleus, Cell Wall, Cell Membrane, Cytoplasm, Nuclear Membrane, and Chloroplasts.
What are things found in an animal cell?
Nucleus, Cytoplasm, Nuclear Membrane, Nucleolus, and a Cell Membrane (No Cell Wall or Chloroplasts).
What cell part name is used to describe the dark center of a frog blood cell?
Nucleus.
Describe the location of the cell membrane.
Outer part of an animal cell, second layer of a plant cell.
Is cork produced by a plant or animal?
Plant
Is Elodea a plant or an animal?
Plant.
Are onions produced by plants or animals?
Plants
What is the shape of the Elodea cell?
Rectangular.
What is the shape of chloroplasts?
Small, round organelles (ovals).
Why were the onion cells stained?
So you can see the cell's structures.
What is the function of a cell's cytoplasm?
Space for work to be done.
What separates the contents of the nucleus from the cytoplasm?
The nuclear membrane.
What is the shape of a nucleolus of an onion cell?
Tiny dots or eye-like structures.
Why was a stain added to the cheek cells?
To make it easier to see the cell's structures.
Are cheek cells alive?
Yes
Can a cell wall be seen in the duckweed cell?
Yes
Is a cell wall present in the onion cell?
Yes
Is the cell wall present in the Elodea cell?
Yes
