Budding is a method of asexual reproduction found in ______.
Ginger is vegetatively propagated through:
Example: Zingiber officinale (ginger), Curcuma longa (turmeric)

There is no natural death in single-celled organisms like Amoeba and bacteria because
During unfavourable conditions, the Amoeba reproduces by:
Sporulation is the process of production of spores which germinates under favourable condition. During favourable condition the encysted amoeba divides by multiple fission and produces pseudopodiospores. This phenomenon is known as sporulation. In order to survive, the unfavourable condition amoeba develops a tough wall around it known as cyst. When the favourable condition approaches the cyst wall bursts out, and the spores are released in the surrounding medium to grow up into many amoebae.

So, the correct answer is option A.
__________ is not a method of vegetative propagation.
Vegetative propagation methods include:
Propagation is the natural mechanism by which plants regenerate.
Hence, the correct option is 'C' i.e. Lytic Cycle
Vegetatively propagated plants are ______.
Therefore, Option C is correct, i.e. Genetically similar.
Which one of the following statements is not correct?
1. In potato, banana, and ginger, the plantlets arise from nodes present in the modified stem.
So, the statement is false.
2. Asexually developed plants are the clone of their own parents because of the fusion of gametes does not take place in vegetative propagation so there is no chance of recombination and variation.
The statement is true.
3. A zoospore is a motile asexual spore that uses a flagellum for locomotion.
The statement is true.
4. Water hyacinth is an aquatic weed which is popularly known as the terror of Bengal because it grows very rapidly and eliminates the growth of several species and even eliminates them.
So, the correct answer is option A.
Vegetative propagation in mint occurs by ______.
Vegetative propagation in Mint:
Which of the following options shows bisexual animals only?
So, the correct answer to the question is earthworm, sponge, and leech. Figure below showing Sponge, Earthworm & Leech.
How many daughter cells are produced when a bacterial cell reproduces asexually?
Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA onto their offspring asexually. In other words, a bacterial cell reproduces by simply replicating its chromosome and dividing it into two daughter cells.
