| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What is the primary difference between prokaryotic and eukaryotic cells? | Prokaryotic cells lack a nucleus and membrane-bound organelles, whereas eukaryotic cells have a nucleus and a variety of membrane-bound organelles. | Think 'pro' for 'before' nucleus—prokaryotes are simpler and lack a nucleus. |
| 2 | Which organelle is responsible for energy production in the cell? | The mitochondrion is responsible for energy production through ATP synthesis. | Mitochondria = the cell's powerhouses. |
| 3 | What is the function of the rough endoplasmic reticulum (RER)? | The RER synthesizes and processes proteins destined for secretion or for use in the cell membrane, due to the presence of ribosomes on its surface. | Rough = Ribosomes attached, focusing on protein production. |
| 4 | Which organelle contains its own DNA and can replicate independently of the nucleus? | Mitochondria contain their own DNA and can replicate independently, playing a role in energy production. | Think 'Mitochondria' as the 'energy DNA' carriers within the cell. |
| 5 | What is the main structural difference between plant and animal cells? | Plant cells have a rigid cell wall, large central vacuole, and chloroplasts, whereas animal cells lack a cell wall and chloroplasts and have smaller vacuoles. | Plant cells are like fortified houses with walls and solar panels (chloroplasts). |
| 6 | Which organelle is involved in the synthesis of lipids and detoxification? | The smooth endoplasmic reticulum (SER) is involved in lipid synthesis and detoxification processes. | Smooth ER handles lipids, no ribosomes attached. |
| 7 | What structure surrounds the cell membrane and provides structural support in plant cells? | The cell wall surrounds the plasma membrane in plant cells, providing rigidity and protection. | Wall = the 'armor' for plant cells. |
| 8 | Describe the function of the Golgi apparatus. | The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. | Think 'mail center' for proteins. |
| 9 | Which organelle is primarily involved in the breakdown of macromolecules and cellular waste? | Lysosomes contain enzymes that digest macromolecules, waste, and damaged organelles. | Lysosomes = the cell's recycling center. |
| 10 | What is the role of the cytoskeleton? | The cytoskeleton provides structural support, maintains cell shape, and facilitates intracellular transport and cell movement. | Cytoskeleton = the cell's internal framework. |
| 11 | Which component of the cell membrane is responsible for its selective permeability? | Phospholipids and embedded proteins work together to regulate what enters and exits the cell, giving the membrane its selective permeability. | Think 'phospholipid bilayer' as the gatekeeper. |
| 12 | What is the function of ribosomes in the cell? | Ribosomes synthesize proteins by translating messenger RNA (mRNA) into amino acid chains. | Ribosomes = protein factories. |
| 13 | Where are chloroplasts found, and what is their main function? | Chloroplasts are found in plant cells and some protists; they carry out photosynthesis to produce glucose using sunlight. | Chloroplasts = solar panels of the plant. |
| 14 | What is the fluid mosaic model of the cell membrane? | It describes the cell membrane as a flexible layer of phospholipids with embedded proteins, resembling a mosaic of diverse molecules. | Think of the membrane as a dynamic mosaic artwork. |
| 15 | Which organelle is involved in the synthesis of steroids and detoxification of harmful substances? | The smooth endoplasmic reticulum (SER) performs these functions. | Smooth ER handles lipids and detox. |
| 16 | What is the function of the nuclear envelope? | The nuclear envelope surrounds the nucleus, controlling the exchange of materials between the nucleus and cytoplasm via nuclear pores. | Envelope = security gate for nuclear contents. |
| 17 | How do prokaryotic cells reproduce? | Prokaryotic cells reproduce mainly through binary fission, a process of asexual division that results in two identical cells. | Binary fission = 'split in two'. |
| 18 | What is the significance of the endosymbiotic theory in cell evolution? | It proposes that mitochondria and chloroplasts originated from free-living bacteria that were engulfed by ancestral eukaryotic cells, leading to symbiosis. | Endosymbiosis = bacteria living inside cells, providing energy or photosynthesis. |
| 19 | Which organelle is responsible for packaging materials into vesicles for transport? | The Golgi apparatus packages proteins and lipids into vesicles for transport within or outside the cell. | Golgi = the cellular post office. |
| 20 | What role do cilia and flagella play in eukaryotic cells? | Cilia and flagella are hair-like structures that facilitate cell movement or move substances over the cell surface. | Cilia = tiny oars; flagella = longer tail for movement. |
