Question

:) Select the correct statement of the following:
a) Once the sporangia are formed they release the spores.
b) Once the spores are ready and mature, the sporangia burst open.
c) Spores remain inside the sporangia forever and never come out.
d) Spores are bodies produced on the filaments of mucor.​

Answer 1

Answer:

b)once the spores are ready and matured , the sporangia burst open

Explanation:

the spores are the seeds of the plant the sporangia is the shell or wall that protects the spores.

Answer 2

Answer:

Option b) Once the spores are ready and mature, the sporangia burst open.

Explanation:

• The spore is the single-celled asexual body involved in asexual reproduction in the lower plants like fungi, bryophytes and pteridophytes, etc.

• Spores are typically so light body surrounded by a thick cell wall for protection.

• The spores are formed by a process of sporogenesis and are accomplished through mitosis or cellular reproduction.

• The sporangium (Plural: sporangia) is the sporophyte that is the spore-bearing organ.

• Once the spores are produced, they need to get out into the world through dispersal adaptations where they can travel, grow and thrive.

• When the spores mature and become a dark coloured mass, the uppermost part of sporangia bursts open and release them. Later these spores germinate under favourable conditions.  

Hence option b) Once the spores are ready and mature, the sporangia burst open is correct.
