Study Notes
Ciliated Cells (Animals)
- Specialized cells with cilia (hair-like structures) that move fluids or particles across surfaces.
- Cilia beat in coordinated waves to move substances.
- Cell body contains the nucleus and organelles.
- Basal body anchors the cilium to the cell membrane.
- Move mucus or particles (e.g., in the respiratory system).
- Aid in locomotion in some unicellular organisms.
- Move fluids in the respiratory tract to protect lungs.
- Located in the respiratory (trachea, bronchi), reproductive (fallopian tubes), and brain (ependymal cells).
- Examples include epithelial cells in the trachea and ependymal cells in the brain.
Palisade Cells (Plants)
- Specialized plant cells in leaves for photosynthesis.
- Contain chloroplasts (with chlorophyll) for photosynthesis.
- Have a cell wall for structural support.
- Also have a nucleus, cytoplasm, and other organelles.
- Photosynthesize, converting sunlight, CO2, and water into glucose (plant food) and oxygen.
- Located in the upper mesophyll layer of leaves for maximum sunlight absorption.
- Tightly packed for maximum light exposure and chloroplast function.
Pollen Cells (Plants)
- Male reproductive cells in plants for fertilization.
- Have a tough exine (outer coating) for protection.
- Include a generative cell that divides to form sperm cells.
- Produce a pollen tube to deliver sperm to the ovule.
- Fertilize the ovule in the female reproductive system.
- Found in the anthers of flowering plants.
- Pollen tube grows down the style to deliver sperm to the ovule after pollination.
Red Blood Cells (Humans)
- Specialized cells transporting oxygen from lungs to tissues and CO2 in the opposite direction.
- Have a biconcave shape for increased gas exchange surface area and narrow capillary passage.
- Contain hemoglobin, a protein that binds and carries oxygen.
- Lack a nucleus for maximum hemoglobin space.
- Transport oxygen from lungs to tissues, and CO2 back to the lungs.
- Located in blood vessels throughout the body.
- Hemoglobin binds oxygen in the lungs, and cells deliver it to tissues while collecting CO2 for expulsion via lungs.
Root Hair Cells (Plants)
- Specialized plant cells in roots for water and mineral absorption.
- Have long, thin root hairs to increase surface area for absorption.
- Composed of a cell wall, nucleus, cytoplasm (for water and mineral movement).
- Absorb water and minerals from the soil using osmosis and active transport.
- Involved in transporting absorbed water and minerals throughout the plant.
- Located in the epidermis of plant roots, close to the tips.
Xylem Cells (Plants)
- Specialized plant cells for water and mineral transport from roots to other parts.
- Form long, tube-like tracheids and vessels.
- Xylem walls are strengthened by lignin.
- Mature xylem cells are dead and hollow.
- Transport absorbed water and minerals throughout the plant.
- Provide structural support due to their strong cell walls.
- Found in the plant's vascular tissue (vascular bundle).
- Water moves upward via transpiration and cohesion (through xylem vessels and tracheids).
Nerve Cells (Neurons) (Humans)
- Specialized cells transmitting electrical signals for communication throughout the body.
- Cell body contains the nucleus to control cell functions.
- Have dendrites (branch-like structures) to receive signals from other neurons.
- Axon is a long extension to carry signals away from the cell body.
- Myelin sheath is a fatty layer surrounding axons to speed signal transmission.
- Synapses are junctions where signals are transmitted through neurotransmitters.
- Transmit electrical signals between brain, spinal cord, and body parts.
- Allow body to respond to stimuli and coordinate actions.
- Located in the brain, spinal cord, and nerves.
- Neurons transmit impulses through axons, communicate at synapses, and enable body responses.
