Lab 4 The Cell Answer Key Essay
Lab 4 – The Cell Answer Key
Procedure 4.3
Draw a picture of a single Elodea cell and label all visible structures.
See the diagram in your lab manual. Without staining, the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts.
Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________
What evidence do you have to support this claim?
The presence of organelles (chloroplasts) and its large size.
Does this cell have a plasma membrane, a cell wall, or both? ________Both_______________
How does this cell obtain the glucose it needs to make ATP?
Photosynthesis
What are the green organelles that are present in Elodea cells? ____Chloroplasts_________ …show more content…
You should have been able to see cytoplasmic streaming (the movement of chloroplasts and other organelles within the cell.
Procedure 4.5
What cellular structure(s) are more visible after staining? The cell walls and the nucleus.
Onions are plants and yet onion bulb cells do not have chloroplasts. Why?
The bulb of an onion (the part we eat) grows underground and thus, is not exposed to sunlight. Photosynthesis requires the presence of sunlight, so chloroplasts are useless.
Procedure 4.7
What is a plastid? Organelles where food is made and stored.
Why are potato amyloplasts dark purple after staining with
