In a developing embryo, analyse the consequences if cell divisions are not followed by cell differentiation.Topic: Biology
‘Fertilisation is not an obligatory event for fruit production in certains plants’. Explain the statement.Topic: Biology
Is it possible to consider vegetative propagation observed in certain plants like Bryophyllum, water hyacinth, ginger etc., as a type of asexual reproduction? Please give two/three reasons.Topic: Biology
With which type of reproduction do we associate the reduction division? Analyse the reasons for it.Topic: Biology
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.
The number of taxa exhibiting asexual reproduction is drastically reduced in higher plants (angiosperms) and higher animals (vertebrates) as compared with lower groups of plants and animals. Help me to analyse the possible reasons for this situation.Topic: Biology
In haploid organisms that undergo sexual reproduction, name the stage in the life cycle when meiosis occurs. Help me to give reasons for answer.Topic: Biology
What do the following parts of a flower develop into after fertilisation?
Match the organisms given in Column-’A’ with the vegetative propagules given in column ‘B’.
iv. Water hyacinth
c. leaf buds
d. bulbilsTopic: Biology
Which of the followings are monoecious and dioecious organisms.Topic: Biology
Why do gametes produced in large numbers in organisms exhibit external fertilisation?Topic: Biology
Help me to give reasons as to why cell division cannot be a type of reproduction in multicellular organisms.Topic: Biology
