Study Notes
Cell Biology Vocabulary Test Study Notes
Part 1: Multiple Choice
- ATP Production: Mitochondria are responsible for producing ATP, the cell's main energy source.
- Protein Synthesis: Ribosomes synthesize proteins.
- Plant Cell Structure: The cell wall provides structural support and protection to plant cells.
- Prokaryotic vs. Eukaryotic Cells: Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.
- Amino Acid Macromolecules: Proteins are made up of amino acids.
- Photosynthesis Organelle: Chloroplasts are responsible for photosynthesis in plant cells.
- Genetic Information Storage: Nucleic acids, specifically DNA, store genetic information.
Part 2: Short Answer
- Golgi Apparatus Function: Modifies, sorts, and packages proteins for secretion or use within the cell.
- Nucleus Function: Contains the cell's DNA, controls cell activities, and is the site of ribosome synthesis.
- Cellular Respiration: The process of converting glucose and oxygen into ATP, the cell's energy currency. Cellular respiration is vital for energy production in all living cells.
- Lysosomes: Contain enzymes to break down waste materials, cellular debris, and foreign particles. They are crucial for maintaining cellular health.
- Monosaccharide vs. Polysaccharide: A monosaccharide is a single sugar molecule (e.g., glucose), while a polysaccharide is a complex carbohydrate composed of multiple sugar units (e.g., starch).
Part 3: Matching
- A. Nucleolus: A structure within the nucleus that helps assemble ribosomes.
- B. Endoplasmic Reticulum (ER): A network of membranes involved in protein modification, folding, and transport.
- C. Cytoskeleton: Provides structural support and facilitates intracellular transport.
- D. Vacuole: A storage organelle, particularly for water and nutrients, especially in plant cells.
- E. Chlorophyll: A green pigment within chloroplasts that absorbs light energy for photosynthesis.
Part 4: True or False
- Mitochondria and Cellular Respiration: True (they are responsible in both plant and animal cells)
- Ribosomes in Prokaryotic Cells: False (Ribosomes are found in both prokaryotic and eukaryotic cells).
- Cell Membrane Function: True (It regulates what enters and leaves the cell).
- Photosynthesis Location: False (Photosynthesis occurs in the chloroplasts, not mitochondria).
- Glucagon and Insulin: True (These are hormones that regulate blood glucose levels).
Part 5: Fill in the Blanks
- Cellular Respiration Process: Cellular respiration
- Single Sugar Unit: Monosaccharide
- Pancreas Cells: Islets of Langerhans (or pancreatic islet cells)
- Protein Synthesis Nucleic Acid: RNA
- Brain Structure: Amygdala (plays a key role in processing emotions and survival instincts)
