Question

Zoospores are
A) motile spores seen in bryophytes
B) motile sexual spores
C) motile asexual spores in fungi
D) motile asexual spores in algae and fungi

Answer 1

Either the disintegration of the zoo sporangial wall or the development of an apical pore on the zoosporangium releases the zoospores. The zoospores swim after liberation, then suspend their flagella, encyst and ultimately germinate into green growth.

Complete Answer:
The only fungus structures that can shift by themselves are zoospores. However, zoospores can only travel with very short distances.

Now, let us find the solution from the options-
- The generation of sporophytes is short-lived. This contains a capsule that develops spores by meiosis and a stem that keeps the gametophyte. When released, the spores are spread by air currents and germinate when they land somewhere wet. This restores the development of gametophytes. A filamentous stage called a protonema is first produced by the spore. Chloroplasts are full of these cells. Thus option A is not the correct option.
- Sexual spores are also thick-walled and are capable of withstanding harsh environmental conditions, like heat treatment, as in the situation of the sexual spores of Byssochlamys, which can ruin fruit juices. Thus, option B is not the correct option.
- A zoospore is an asexual motile spore which uses a locomotion flagellum. Often referred to as a swarm spore, certain bacteria, fungi, and bacteria produce these spores to disperse themselves. Thus, option C is not only the correct option.
- Zoospores are considered the motile reproductive systems of algae and fungi that specifically give birth to new individuals. It is a motile spore that is asexual. For locomotion, it requires flagella

Thus, the correct answer is option (D) motile asexual spores in algae and fungi.

Note: The mechanism through which zoospores are drawn to their hosts is not entirely clarified, but several variables may be involved. With respect to chemical, nutritional, ionic or energetic gradients, zoospores display lateral swimming responses.
