Zoospores are the most common asexual spores in green algae. Which structural property guarantees their functional role in disperse phase propagation?

1. They are non-motile, thick-walled resting spores produced during extreme desiccation.
2. They are produced inside oogonia via meiotic reduction division.
3. They are diploid vegetative fragments formed by cell wall cleavage.
4. They are flagellated, motile spores that germinate directly into new plants.
