Question 7

To answer how blood cells differ from plant cells:

• Color: Blood cells (e.g., human red blood cells) are often pale pink/red (due to hemoglobin), while plant cells (e.g., onion epidermis) are typically colorless or have natural pigments (green from chloroplasts in leaf cells).
• Shape: Blood cells (red) are biconcave discs (no nucleus in mammals), plant cells have a rigid, fixed shape (rectangular/ polygonal) due to the cell wall.
• Size: Blood cells (red) are smaller (∼7 - 8 μm diameter), plant cells (e.g., onion) are larger (∼10 - 100 μm, varies by type).

This is a practical lab task. Choose slides (e.g., onion epidermis, cheek cells, bacteria) and record magnification (e.g., 40x, 100x, 400x) and slide name.

Answer:

• Color: Blood cells (e.g., red blood cells) may appear red/pink (from hemoglobin), while plant cells (e.g., onion) are often colorless or green (with chloroplasts).
• Shape: Blood cells (red) are biconcave discs (flexible, no fixed shape without a wall), plant cells have a rigid, polygonal/rectangular shape (due to the cell wall).
• Size: Blood cells are generally smaller (e.g., red blood cells: ~7–8 μm) than many plant cells (e.g., onion epidermal cells: ~10–100 μm).
