Lecture 1 : Asexual reproduction ; Sexual reproduction

what is repro ?

Rose plants produce large, attractive bisexual flowers but they seldom
produce fruits. On the other hand a tomato plant produces plenty of
fruits though they have small flowers. Analyse the reasons for failure of
fruit formation in rose.

Enumerate the differences between asexual and sexual reproduction.
Describe the types of asexual reproduction exhibited by unicellular
organisms.

Justify the statement ‘Vegetative reproduction is also a type of asexual
reproduction’.

Is it possible to consider vegetative propagation observed in certain plants
like Bryophyllum, water hyacinth, ginger etc., as a type of asexual
reproduction? Give two/three reasons.

Honeybees produce their young ones only by sexual reproduction.
Inspite of this, in a colony of bees we find both haploid and diploid
individuals. Name the haploid and diploid individuals in the colony and
analyse the reasons behind their formation.

In haploid organisms that undergo sexual reproduction, name the stage
in the life cycle when meiosis occurs. Give reasons for your answer.

Is the presence of large number of chromosomes in an organism a
hindrance to sexual reproduction? Justify your answer by giving suitable
reasons.

The probability of fruit set in a self-pollinated bisexual flower of a plant
is far greater than a dioecious plant. Explain.

Rearrange the following events of sexual reproduction in the sequence
in which they occur in a flowering plant:

Why do we refer to offspring formed by asexual method of reproduction
as clones?

Mention two inherent characteristics of Amoeba and yeast that enable
them to reproduce asexually.

Give any three differences between asexual and sexual reproduction.

Why is syngamy a major event in sexual reproduction?

Mention the different stages of sexual reproduction.

How will you grow a banana and a ginger plant?

State the function of a vegetative propagule.

What is a bisexual flower? Collect five bisexual flowers from your neighborhood and with the help of your teacher find out their common and scientific names.

Distinguish between asexual and sexual reproduction. Why is vegetative reproduction also considered as a type of asexual reproduction?

How does the progeny formed from asexual reproduction differ from those formed by sexual reproduction?

Offspring formed due to sexual reproduction have better chances of survival. Why? Is this statement always true?

Why is the offspring formed by asexual reproduction referred to as clone?

Which is a better mode of reproduction sexual or asexual? Why?
