7. Eukaryotic cells typically range in size from:

1 to 10 nm

8. Prokaryotic cells reproduce primarily by:

Mitosis
Meiosis
Binary fission
Budding

9. Sexual reproduction in prokaryotes involves:

Meiosis and fertilization
Conjugation, transformation, or transduction
Spore formation
Gamete fusion

1. Which of the following describes the most fundamental difference between prokaryotic and eukaryotic cells?

Presence of ribosomes
Presence of a cell membrane
Presence of a nucleus
Presence of cytoplasm

36. Which of these structures is essential for maintaining turgor pressure in plant cells?

Cell membrane
Mitochondrion
Chloroplast
Central vacuole

37. The presence of a cell wall prevents animal cells from:

Performing photosynthesis
Undergoing cellular respiration
Bursting in hypotonic solutions
Synthesizing proteins

38. The flexible nature of the animal cell membrane allows for processes like:

Photosynthesis
Endocytosis and exocytosis
Turgor pressure maintenance
Cell wall synthesis

39. The main difference in energy acquisition between typical animal and plant cells is that plant cells can:

Only respire aerobically
Perform photosynthesis
Only respire anaerobically
Obtain energy from external sources only

40. When a plant cell is placed in a hypotonic solution, it becomes turgid. What happens to an animal cell in the same solution?

It shrinks.
It bursts (lyses).
It becomes turgid.
It remains unchanged.

41. When an animal cell is placed in a hypertonic solution, it undergoes:

Lysis
Turgor
Crenation
Plasmolysis

42. When a plant cell is placed in a hypertonic solution, it undergoes:

Lysis
Turgor
Crenation
Plasmolysis

43. Which organelle is responsible for packaging and modifying proteins and lipids for secretion or delivery to other organelles in both cell types?

Endoplasmic Reticulum
Ribosomes
Golgi Apparatus
Lysosomes

44. The presence of plastids, such as amyloplasts (for starch storage), is characteristic of:

Animal cells
Plant cells
Fungal cells
Bacterial cells

29. If you observe a cell under a microscope and identify a cell wall, chloroplasts, and a large central vacuole, you are most likely looking at a:

Bacterial cell
Animal cell
Plant cell
Fungal cell

45. The cell membrane in both animal and plant cells is described as:

Fully permeable
Impermeable
Selectively permeable
Non-permeable

30. If you observe a cell under a microscope and note the absence of a cell wall and chloroplasts, along with the presence of small vacuoles and centrioles, you are most likely looking at an:

Animal cell
Plant cell
Bacterial cell
Fungal cell

46. Which of the following organelles is NOT typically found in an animal cell?

Nucleus
Mitochondrion
Chloroplast
Ribosome

31. Both animal and plant cells are classified as:

Prokaryotic
Eukaryotic
Archaea
Monera

47. Which of the following is present in a plant cell but usually absent in an animal cell?

Cytoskeleton
Vacuole (large central)
Cell membrane
Cytoplasm
