  4. All except III
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Reproduction is the biological process, through which a new organism produced from their parents. It is of two types - sexual reproduction, asexual reproduction. Asexual reproduction occurs through the involvement of the single parent. It occurs by many methods e.g .budding, fragmentation, spores. Asexually reproduce offspring is an identical copy of their parents. Sexual reproduction occurs through the involvement of two parents. It occurs through the male and female gametes. Sexually reproduce offspring are less similar to their parents. Reproduction is always observed in living organisms.

So, the correct answer is 'All of the above',

Multiple choice botany modes of reproduction why do plants reproduce? reproduction and variation the life cycle of plants

Reproduction is the characteristics of living organisms, but it cannot be regarded as defining property because

  1. Asexual reproduction involves only single parent

  2. Lower organisms do not reproduce under stressful environmental conditions

  3. All living beings do not have the capacity to reproduce

  4. For lower plants growth and reproduction are mutually inseparable phenomenon
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Reproduction is the process by which living organisms produce new offspring similar to themselves.
  • All living organisms do not have the capacity to reproduce. For example worker honeybees, mule or sterile human couples. Despite their inability to reproduce, they show other characteristics of living organisms.


So, the correct option is 'All living beings do not have the capacity to reproduce'

Which of the following is associated with reproduction?

  1. Parthenogenesis

  2. Fertilization

  3. STDs

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization.
Fertilization is the action or process of fertilizing an egg or a female animal or plant, involving the fusion of male and female gametes to form a zygote.
STDs stands for sexually transmitted disease. It is the infection transmitted through sexual contact, caused by bacteria, viruses or parasites.
So, the correct answer is option D.

Reproduction is a .......... process of life.

  1. Structural

  2. Metabolic

  3. Fundamental

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reproduction is the process of continuation of a species. It is a mode of production of new organisms, called offsprings, from their parents. Each organism exists due to reproduction. With every new offspring, genetic variations are passed from the parents, that help the offspring survive better in the environment. Such variations and adaptations contribute to a species sustaining life for a longer duration.

Which of the following process of maintains the existence of the species on the earth?

  1. Metabolism

  2. Reproduction

  3. Adaptation

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism.
Reproduction is a biological process by which new individual organisms or offspring are produced from their parents. It is a fundamental feature of all known life and each individual organism exists as the result of reproduction.
Adaptation is the process of change by which an organism or species becomes better suited to its environment.
So, the correct answer is option B.

During the development of ascus and basidium, which one of the following phenomena is common to both?

  1. Exogenous development of reproductive spores

  2. Fusion of two nuclei and subsequent meiotic division

  3. Crozier formation and clap connection

  4. Endogenous development of reproductive spores
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In both ascus (fungal asci) and basidium development, the fundamental common step is karyogamy, which is the fusion of two haploid nuclei, immediately followed by meiotic division to produce haploid spores. Spore development type and accessory structures like croziers vary between groups.

What is the importance of reproduction?

  1. Regeneration

  2. Replication

  3. Both A and B

  4. Regeneration and passing genes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

  • Reproduction is the method of making a copy of organisms or reproducing young ones. During reproduction, meiosis is the first stage by which gametes are prepared. 
  • Each gamete contains a copy of male or female parents. When a zygote is formed by the fertilization of the gametes, the genetic copy of both the parents come into the offspring. Thus, it helps in the passing of genes.

 Therefore, the correct answer is option D.

Which one the following is a requirement for sexual reproduction?

  1. Male and female parents

  2. Production of gametes

  3. Optimal environmental conditions

  4. Aquatic habitat
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sexual reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female). Nearly all animals employ a diploid-dominant life-cycle strategy in which the only haploid cells produced by the organism are the gametes. Early in the development of the embryo, specialized diploid cells, called germ cells, are produced within the gonads (such as the testes and ovaries)

So, the correct answer is 'production of gametes'

Reproduction may be defined as a phenomenon by which organisms

  1. Increase in size

  2. Produce progeny of their own kind

  3. Are produced from single fertilized eggs

  4. Form new tissues and organs
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Reproduction  is the biological process by which new individual organisms – offspring – are produced from their parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. Reproduction in human beings is by sexual reproduction where both the male and female gametes fertilize to give rise to an embryo. The fertilization of human embryo occurs inside the body of the female 

So, the correct answer is 'produce progeny of their own kind'

  1. Metamarphosis

  2. Fertilization

  3. Cloning

  4. None of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Metamorphosis is the biological process where a larva transforms into an adult through drastic changes in body structure and physiology. This process is common in insects, amphibians, and other organisms. Fertilization is the fusion of gametes, cloning creates genetic copies, and metamorphosis is the correct term for this transformation.
