WebMay 4, 2024 · Plant cells do not have cilia, which are short projections from the cell that function in movement, but the sperm cells of early diverging plants, like bryophytes and seedless vascular plants, have flagella. These are long projections that function in movement. Microtubules are also are guides for the construction of the cell wall, and ... WebUndulipodia use a whip-like action to create movement of the whole cell, such as the movement of sperm in the reproductive tract, and also create water movement as in the choanocytes of sponges. [citation needed]Motile (or secondary) cilia are more numerous, with multiple cilia per cell, move in a wave-like action, and are responsible for movement …
