BIO LAB EXAM 2 (LABS 3, 4, 5) EXAM
QUESTIONS AND ANSWERS (VERIFIED
AND UPDATED)
Unicellular (lab 3) - ANS A single celled organism
Multicellular (lab 3) - ANS made of many cells
prokaryotic cell (lab 3) - ANS -lack a membrane bound nucleus
-lack membrane bound organelles
-typically unicellular & very small
-includes Bacteria & Archaea
eukaryotic cell (lab 3) - ANS cell that has a nucleus and other membrane-bound organelles
-ex: plants, fungi, animals, algae
- includes Eukarya
3 domains of life (lab 3) - ANS Bacteria, Archaea, Eukarya
which domains are more closely related (lab 3) - ANS Archaea and Eukarya
cell theory (lab 3) - ANS - all organisms are composed of cells
@2026/2027 ALLRIGHTS RESERVED.
, - cells are the basic living, functioning units of all organisms
- all cells come from pre existing cells
endosymbiotic theory (lab 3) - ANS Eukaryotic cells evolved from prokaryotic cells
endosymbiotic evidence (lab 3) - ANS - mitochondria & chloroplast have their own DNA
- both are structurally similar to prokaryotic cells
- both are able to reproduce themselves by a process similar to prokaryotes
all cells have (lab 3) - ANS DNA, cytoplasm, plasma membrane, ribosomes
- "Dude, CPR"
methyl blue (lab 3) - ANS stains negatively charged particles in a cell, such as DNA, RNA,
proteins, and phospholipids; makes the fragments visible
plant cells only have (lab 3) - ANS cell wall and chloroplasts
iodine (lab 3) - ANS reacts with starch to produce a blue-black color in the cell
Why might the cell theory actually be considered a law? (lab 3) - ANS Cell theory describes a
repeated pattern in nature.
You may place _____ in your mouth to see if it alters the reaction with the stains/indicators. (lab
3) - ANS nothing
TRUE or FALSE: You will lose points if you get any liquid stains on your lenses. (lab 3) -
ANS false
