Appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because

nodes have non-photosynthetic cells

nodes have meristematic cells

nodes are located near the soil

nodes are shorter than intemodes

cycle occurs in non-primate mammals like cows and dogs.

Plants produced through vegetative propagation are called clones.

False

True

Identify the correct sequence of events.

Gametogenesis → Syngamy → Zygote

Gametogenesis → Syngamy Embryogenesis → Zygote

Gametogenesis → Zygote → Syngamy → Embryogenesis

Gametogenesis → Embryogenesis → Zygote → Syngamy

are the motile microscopic structures produced by many algal species.

Sugarcane is propagated by

stem cutting

root cutting

leaf buds

seeds

There is no natural death in single celled organisms like Amoeba and bacteria because-

they cannot reproduce sexually

they reproduce by binary fission

parental body is distributed among the offspring

they are microscopic

The offspring of animals are vulnerable to predators.

10.

The most significant feature of vegetative propagation is that

it is a method of producing a large number of individuals genetically identical to the parent.

it ensures that the progeny individuals are resistant to diseases and pests.

it is a method of producing a large number of individuals genetically different from the parent.

it is an age old practice.

11.

Development of unfertilised ovum into a new individual is called .

12.

In animals, juvenile phase is followed by-

old age

senescent phase

vegetative phase

reproductive phase

13.

There are various types of reproduction. The type of reproduction adopted by an organism depends on

morphology and physiology of the organism

morphology of the organism

the organism’s habitat, physiology, and genetic makeup

the habitat and morphology of the organism

14.

Bony fishes, bryophytes and pteridophytes show internal fertilisation.

True

False

15.

17.

The terms homothallic and monoecious are used to denote

staminate flowers

pistillate flowers.

unisexual condition

bisexual condition

18.

In oviparous animals like reptiles and birds, the fertilised egg is covered by a shell and laid in a safe place.

19.

Vegetative propagation in Pistia occurs by

offset

runner

rhizome

sucker
