How do organisms reproduce class 10 questions and answers
Table of Contents
This Free PDF Notes contains How do organisms reproduce important questions for upcoming government exams. In addition, Organisms reproduce to produce offspring that inherit their genetic material. Reproduction is an important process for the survival of a species because it allows for the continuation of the species and the passing on of genetic traits to the next generation. There are two main types of reproduction: asexual reproduction and sexual reproduction.
Asexual reproduction involves the production of offspring from a single parent, without the involvement of fertilization or the formation of gametes. Asexual reproduction can occur through various methods, such as binary fission, budding, fragmentation, and vegetative reproduction. Single-celled organisms, such as bacteria and protists, typically reproduce asexually.
How do organisms reproduce
Sexual reproduction involves the production of offspring from two parents through the fusion of gametes, which are specialized cells that contain half the genetic material of the parent organism. It allows for the creation of genetically diverse offspring, which can be beneficial for the survival of a species in changing environments. Sexual reproduction occurs in both multicellular animals and plants.
In sexual reproduction, meiosis is a process that occurs in the production of gametes, in which the number of chromosomes is halved through a series of cell divisions. This is followed by fertilization, in which the gametes fuse to form a zygote, which develops into an offspring.
You can download solutions for CBSE Class 10 Science Chapter 8 – How do Organisms Reproduce. These questions are prepared by expert biology teachers based on CBSE NCERT Science books. However, How do organisms reproduce class 10 extra questions and answers is very important to crack any SSC, UPSC, IAS, Railway, RRB NTPC exams in India.
Plants can reproduce sexually through the production of seeds, which contain the genetic material of the parent plant, or asexually through the production of vegetative structures, such as bulbs, rhizomes, or stem cuttings.

Animals can reproduce sexually through the production of eggs and sperm, which fuse during fertilization to form an embryo. Some animals can also reproduce asexually through methods such as parthenogenesis, in which an egg develops into an offspring without fertilization, or by producing offspring through cloning.
Sexual reproduction has the advantage of creating genetically diverse offspring, which can increase the chances of survival in changing environments. However, it also has the disadvantage of being a slower process compared to asexual reproduction, as it requires the production of gametes and fertilization. Asexual reproduction, on the other hand, is a faster process, but it does not allow for the creation of genetically diverse offspring.
- Reproduction is the process of producing new individuals of the same kind.
- Organisms reproduce in two ways- asexually and sexually.
- Asexual reproduction does not involve the fusion of male and female gametes. This takes place in bacteria, amoeba, hydra, etc.
- Sexual reproduction involves the fusion of male and female gametes and can be seen in humans and many animals.
- Fission, budding, vegetative propagation, fragmentation are some different types of asexual reproduction. It does not require any reproductive organs.
- Sexual reproduction involves the reproductive organs of male and female.

How do organisms reproduce class 10 important questions pdf is very important for class 10 students and SSC, Railway competitive exams point of view. Distinguishable organisms reproduce in distinct practices . Let us have a blow-by-blow visage at how distinctive organisms reproduce. The organisms reproduce in two ways, 1.

Fission takes emplacement in unicellular organisms. It’s of two types – Binary fission and multiple fission. Binary Fission – The organisms reproduce by binary fission exclusively when satisfactory quantities of food and moistness is out there. In this, the mommy cell divides into two daughter cells, each bearing a nucleus. Amoeba divides by binary fission. Multiple Fission – The unicellular organisms reproduce by multiple fission when the contingencies are unfavourable with no respectable quantities of food, humidity, and temperature. In this, the organism forms a tubercle around itself. The nucleus divides, and every daughter nuclei is encircled by a membrane. When the stipulations are appreciative anew, the tubercle dissolves and also the daughter nuclei are unleashed, which latterly develops into an separate cell. Plasmodium and Entamoeba endure this procedure.
- What is vegetative propagation ?
- Answer: It is the formation of new plants from vegetative parts (e.g., stem, leaf, root, bud) of a parent plant.
- List two functions performed by ovaries in a human female.
- Answer: Formation of ova
- Secretion of hormones, estrogen and progesterone.
- What is the effect of DNA copying which is not perfectly accurate in the reproductive process ?.
- Answer: It produces mutations which give rise to useful, harmful and neutral variations in the progeny.
- Mention the common mode of reproduction found in Amoeba and Planaria.
- Amoeba Binary fission in any plane.
- Answer: Planaria: Transverse binary fission.
