III. Prokaryotic and Eukaryotic Cells

Question 1

Q: What is the main difference between prokaryotic and eukaryotic cells?

Answer 1

A: Prokaryotic cells lack a membrane-bound nucleus; their DNA is in a nucleoid region, while eukaryotic cells have a membrane-bound nucleus

Question 2

Q: Do prokaryotic cells have membrane-bound organelles?

Answer 2

A: No, prokaryotic cells do not have membrane-bound organelles like the nucleus, mitochondria, Golgi apparatus, chloroplasts, lysosomes, or endoplasmic reticulum.

Question 3

Q: What is the structural difference in DNA between prokaryotes and eukaryotes?

Answer 3

A: Prokaryotic cells have a single circular DNA molecule, while eukaryotic cells have multiple linear DNA molecules organized into chromosomes.

Question 4

Q: How do prokaryotic and eukaryotic cells reproduce?

Answer 4

A: Prokaryotes reproduce by binary fission, while eukaryotes use mitosis and meiosis.

Question 5

label parts of leaf cell tissue

Answer 5

Epidermis, cuticle, stomata, guard cells, palisade mesophyll, spongy mesophyll, vascular bundle (xylem, phloem), vein

Question 6

Parts found in animal cells

Answer 6

Cell membrane, cytoplasm, nucleus, ribosomes, mitochondria, endoplasmic reticulum (rough and smooth), Golgi apparatus, lysosomes, vacuoles, cytoskeleton, centrosome, peroxisomes

Question 7

Q: What are the steps to prepare a wet mount of cheek cells for microscope observation?

Answer 7

1. Prepare a clean object glass with a few drops of water.
2. Scrape the inside of your cheek with a wide-tipped toothpick and mix it in the water.
3. Carefully cover with a cover glass, avoiding air bubbles.
4. Clean any excess water outside the cover glass.
5. Observe under a microscope starting with low magnification, then switch to 40x magnification

Question 8

cells observed during lab?

Answer 8

epithelial cheek cell, red onion, rhoeo discolor, preserved animal cell (emphysema?), dicotyledon cell, aspergillus conidiophores?

tbh dont memorise this
