Study Notes
Specialized Cells
- Specialized cells are modified to perform specific functions in the body of an organism, adapting through changes in size, shape, etc.
Function of Different Specialized Cells
- Red blood cells: contain hemoglobin to carry oxygen around the body
- Sperm cells: male reproductive cells for sexual reproduction, fuse with the egg to produce offspring
- Ovum or egg cells: female reproductive cells for sexual reproduction
- White blood cells: defend the body against infections
- Nerve cells: transmit nerve impulses from one part of the body to another
- Muscle cells: facilitate movement of body parts
Specialized Cells in Plants
Root Hair Cells
- Cover the outside surface of roots with tiny 'hairs' that poke into the soil
- Absorb more water and minerals from the soil
Xylem Cells
- Transport water from the roots to other parts of the plant
Phloem Cells
- Transport sugary water from the leaves to the rest of the plant
Guard Cells
- Allow gas exchange and control water loss within the leaf
- Open or close to regulate the flow of materials into or out of the leaf based on the plant's condition
This quiz covers the characteristics and functions of specialized cells in the human body, including red blood cells, sperm cells, ovum or egg cells, and white blood cells.
