Study Notes
Sperm and Egg Cells
- Sperm cells possess a tail, facilitating movement towards the egg.
- The sperm's head houses genetic material, transmitting male parental genes through its nucleus.
- Egg cells are significantly larger than sperm cells and are round in shape.
- Egg cells contain yolk, which serves as an energy source during early developmental stages.
- The nucleus of the egg cell contains the genetic material from the female parent.
Cell Comparison Chart
-
Sperm Cell:
- Shape: Head with middle piece and a tail.
- Genetic Information: Derived from male parent.
- Energy Storage: None.
- Size: Small.
-
Egg Cell:
- Shape: Round.
- Genetic Information: Derived from female parent.
- Energy Storage: Contains yolk.
- Size: Large.
Calculating Size of Cells
- The formula for determining the actual size of a cell is:
- actual size = image size / magnification
- Example provided: A sperm cell image measures 20mm at a magnification of 500, resulting in an actual size of 0.04 mm.
Key Concepts
- Cells undergo structural and shape changes during their development.
- Specialized cells are adapted for specific functions, exemplified by ciliated cells, which feature cilia to aid in moving mucus along the windpipe.
