Study Notes
Specialized Animal Cells
- Nerve cells (neurons): Possess a large cell body and extensions (dendrites and axons) for transmitting electrical signals. Dendrites receive signals, axons transmit signals.
- Red blood cells: Disc-shaped, flexible cells lacking a nucleus to facilitate oxygen transport. Contain hemoglobin, a protein that binds oxygen.
- White blood cells: Engulf and destroy damaged cells and invaders; have extensions for movement and engulfing prey. Contain toxic chemicals.
- Bone cells: Form layered columns (osteons) with a central canal for blood vessels. Cells on the outside have extensions for communication.
- Skin cells: Protective layers, cells regenerate pushing newer cells towards surface. Protect from water loss and regulate temperature.
- Muscle cells: Contain contracting fibers to enable movement. Fibers appear as step-like structures in high-powered microscope.
- Fat cells: Round, cloudy due to fat storage; cushions organs, insulation, energy source. Nucleus is pushed toward edge by large vacuole.
- Sperm cells: Tadpole-shaped with a flagellum for movement; half the DNA of a body cell; carry DNA for fertilization.
- Goblet cells: Long, tube-like; secrete mucus; aid nutrient/digestive juice absorption.
Specialized Plant Cells
- Guard cells: Found in pairs on leaves; turgor pressure regulates opening/closing of stomata (pores) for gas exchange.
- Palisade mesophyll cells: Upper layer of leaf; have many chloroplasts for photosynthesis, maximize sunlight absorption.
- Spongy mesophyll cells: Lower layer of leaf; irregularly shaped, loosely packed; allow gas exchange for photosynthesis.
- Phloem cells: Transport dissolved sugars and nutrients throughout the plant. Structure has sieve-like connections.
- Xylem cells: Dead cells forming tubes for efficient water and mineral transport from roots to other parts of the plant. Strong lignin inside for support.
- Epidermal cells: Outermost protective layer of plant organs. Can form waxy cuticle layer on leaves or hair-like structures.
- Storage cells: Synthesize starch and stockpile it in amyloplasts for later use; often in seed, fruit and roots.
Cell Matching and Structure
- Specialized cell: Based on their function, certain organelles are more prevalent in one cell type. Muscle cells have more mitochondria for energy production.
- Fat cells: Contain vacuoles for storing large amounts of fat.
- Sperm cells: Abundant mitochondria to power their movement.
- White blood cells: More lysosomes for digestion of foreign particles.
- Muscle cells: Many mitochondria for ATP (energy) production, and ribosomes for protein synthesis.
