* Sperm cells: These are actually motile plant cells, meaning they can move. They have flagella, whip-like structures that propel them through the water, allowing them to reach the egg cell for fertilization.
It's important to note that sperm cells are specialized cells with a specific function in reproduction, and they aren't typical examples of the general plant cell.
While other plant cells don't swim in the same way as sperm cells, some do exhibit cytoplasmic streaming, a type of internal movement within the cell. This movement helps distribute nutrients and organelles throughout the cell, but it's not considered swimming.
So, the short answer is: Only plant sperm cells swim.
