Which of the following plant can be vegetatively propagated by leaf?

• Bryophyllum

• Carrot

• Ginger

• None of these

Answer explanation

Leaves of a number of plants possess adventitious buds for vegetative propagation. For example: Bryophyllum. Hence bryophyllum can be vegetatively propagated by leaf. Carrot can be vegetatively propagated by roots and ginger can be vegetatively propagated by stem.

Which of the following statement is correct? 1. Hydra reproduces by the process of regeneration. 2. Hydra reproduces by the process of budding.

• Only statement 1

• Only statement 2

• Both statement 1 and statement 2

• Neither statement 1 nor statement 2

Answer explanation

Hydra reproduces by the process of regeneration as well as by the process of budding. Hence both statements are correct.

• Amoeba

• Plasmodium

• Leishmania

• Bacteria

What factors are responsible for the rapid growth of Rhizopus on the bread?

• Formation of sporangia

• Large number of spores

• Presence of hyphae

• All of these

Answer explanation

Rhizopus is a fungus. On bread the fungus grows rapidly because of presence of large number of spores. These spores germinate at appropriate temperature and moisture and new fungus is grown and spreads on the whole bread.

Asexual reproduction is seen in the members of kingdom:

• Monera

• Plantae

• Animalia

• All of these

Answer explanation

We know that bacteria, sugarcane and hydra reproduces by asexual reproduction. All prokaryotic unicellular organisms are members of kingdom monera. All plants are member of kingdom plantae and animals are member of kingdom animalia. So bacteria belongs to kingdom monera, sugarcane belongs to kingdom plantae and hydra belongs to kingdom animalia. That's why asexual reproduction is seen in members of kingdom monera, plantae and animalia.

Shubham is studying about the process of regeneration in planaria. He removed the head of planarial worm from its body. What will happen to the two body fragments of planarial worm?

• The planarial worm will die

• The removed head will grow into new planarial worm while body without head will die

• The body will grow into new planarial worm while the removed head will die

• Both removed head and body without head will grow into new planarial worms

Answer explanation

Planarial worms reproduces by the process of regeneration. This is one of the type of asexual reproduction. In the process of regeneration the body parts that are cut from the body develops into new organism. If planaria, is cut down into different parts, each part develops into a new planaria. Hence option 4 is the right answer.
