Lab Report Format Expectations
Utilize college level grammar and professional formatting when completing this
worksheet. Submissions without proper formatting, all required photos or
sufficient responses will be rejected.
Pre-lab Questions
1. Identify the major similarities and differences between prokaryotic and
eukaryotic cells. Both have a cell membrane, cytoplasm, DNA, and
ribosomes. Prokaryotes lack a nucleus and organelles, while eukaryotes
have both.
2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a
eukaryotic cell? DNA is in the nucleoid region in prokaryotes and inside
the nucleus in eukaryotes.
3. Name three structures which provide support and protection in a
eukaryotic cell. Cell membrane, cytoskeleton, and in plant cells, the
cell wall.
EXPERIMENT 1: CELL STRUCTURE AND FUNCTION
Introduction Questions
1. What is the difference between the rough and smooth endoplasmic reticulum?
Rough ER has ribosomes for protein synthesis, smooth ER does not and helps
with lipids.
, 2. Would an animal cell be able to survive without a mitochondria? Why
or why not? No, because mitochondria make ATP, which powers
cellular functions.
3. What is the function of a lysosome?
Lysosomes break down waste and recycle materials within the cell.
