Bacterial cells, spermatozoa i.e. human sperm cell, green algae, ferns, mosses and some gymnosperms.
some plant cells do, which swim about. others don't.
It is said that some plant sex cells contain a flagella.
Not all prokaryotic cells have flagella only some do. The flagella in prokaryotic cells are made up of the hook, filament and basal body.
Generally not, although some plant sperm do have flagella.
Yes some cells have. Sperms are good example
there are no animal cells that have a flagella, as animal cells, for the most part are stationary. Some move with aid by blood, etc. Only prokaryotes (Bacteria) have flagella, and only certain ones. I hope this clarifies the situation for you.

Well the flagella works as a propeller to help the cells move. However plant cells dont actually have flagella or cilia because they dont need to move. Some plants (bryophytes?) have motile sperm that have flagella. Also, only prokaryotic flagella work like propellers. Eukaryotic flagella whip back and forth rather than rotating.
Cilia and flagella assist in the movement of cells. Not all cells have them, but they are very common in prokaryotic cells. They are usually long, and appear to be projections of the cell. Without them, some cells would be unable to function. For example, sperm cells require flagella to move towards the egg.
Flagella are not cells - they are extensions of cells that render the cell motile. (Think of it as a tail of some sort.) Sperms have flagella and other unicellular organisms such as paramecium and other organisms such as bacteria have flagella too. It isn't common for plant cells to have flagella.
Most plant cells have neither flagellum nor cilium but in some cases there are exceptions. For example, the cycads have some cells with cilia and flagella. In particular, sperm cells have a flagella.
