Reproduction (or procreation or breeding) is the biological process by which new individual organisms – “offspring” – are produced from their “parent” or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction.
How do we reproduce and develop?
Humans Must Develop Male or Female Gonads and Genitalia to be Capable of Reproduction. Reproductive structures begin to form in the embryonic stage. By week 6, gonads and genitalia are present but undifferentiated. Whether they become male or female is determined by one chromosome delivered by the sperm.
What is reproduction in biology?
Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique. In asexual reproduction, one parent copies itself to form a genetically identical offspring.
What is reproduction and answer?
Reproduction means to reproduce. It is a biological process by which an organism reproduces an offspring who is biologically similar to the organism. Reproduction enables and ensures the continuity of species, generation after generation. It is the main feature of life on earth.What is reproduction and example?
Reproduction is defined as the creation of a copy of something, a copy of something, or the act of sexual intercourse to create an offspring. An example of a reproduction is a copied drawing. noun.
What is cell growth and reproduction?
– Offspring produced by sexual reproduction inherit some of their genetic information from each parent. – Chromosomes make it possible to separate DNA precisely during cell division. – During the cell cycle, a cell grows, prepares for division, and divides to form two daughter cells.
What is 12th reproduction?
Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself. The offspring grow, mature and in turn produce new offspring. Thus, there is a cycle of birth, growth and death. Reproduction enables the continuity of the species, generation after generation.
How do you explain fertilization to a child?
Fertilization, simply, is the joining of an egg and a sperm. It happens inside a woman’s reproductive system and is the first step of a pregnancy. It specifically involves the joining of the female reproductive cells (egg) with the male reproductive cell (sperm).How do eggs become embryos?
The egg travels from the ovary to the fallopian tube, and there it will stay until it is successfully fertilized by a single sperm. After successful fertilization, the sperm and egg grow into an embryo. The process of becoming an embryo is fast: every 12-14 hours the embryo divides.
What is reproduction short answer 6th?Answer: Reproduction is the biological process by which new organisms are generated from their parents. It is the mechanism of species continuation. There are two means of reproduction: asexual and sexual reproduction.
Article first time published onWhat is definition of reproduction Class 10?
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.
What is meant by reproduction Class 6?
Reproduction is a biological process through which living organisms produce offspring similar to themselves. Living organisms reproduce to maintain their number and continuation of their species. Concept insight: Reproduction ensures the continuation of similar kinds of individuals.
What is growth and development in science?
“Growth” simply means “an increase in size and mass of a particular organism over a period of time.” “Development” is defined as “a process wherein a particular organism transforms itself from a lone cell into a more complicated multicellular organism.”
What is reproduction in Brainly?
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. There are two forms of reproduction: asexual and sexual.
Why do we reproduce?
Reproduction is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. … Asexual reproduction refers to simple cell division that produces an exact duplicate of an organism.
What is reproduction and types?
There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.
How do you reproduce?
It typically involves sexual intercourse between a sexually mature male and female. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman’s ovum by the man’s sperm.
What is reproduction write its types?
There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction.
What is biology class 11?
Biology is the study of all the concepts of natural science of life and living organisms. It comprises of living organisms’ physical structure, important molecular interactions, chemical processes, physiological mechanisms, development and evolution. Biology also tells us how cells and organisms work.
What is the chromosome?
(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
What are reproductive cells called?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. … During fertilization, a spermatozoon and ovum unite to form a new diploid organism.
What are the 4 stages of cell reproduction?
Divide into four phases the reproduction process of chromosomes in plant and animal cells. Mitosis has four stages: prophase, metaphase, anaphase, and telophase. Encyclopædia Britannica, Inc.
What happens when sperm enters a woman?
Once the sperm have entered the uterus, contractions propel the sperm upward into the fallopian tubes. The first sperm enter the tubes minutes after ejaculation. The first sperm, however, are likely not the fertilizing sperm. Motile sperm can survive in the female reproductive tract for up to 5 days.
How long does boy sperm stay alive?
The limited window of opportunity for fertilization to occur is about 12-24 hours. Most sperm only live for a maximum of five days after ejaculation. Typically a sperm with the female (X) chromosome is bigger, moves slower and lives longer than a sperm with the male (Y) chromosomes.
How long can sperm live?
When sperm are inside women’s body, they can live for up to 5 days. If you’re a man and you have sex even a few days before your partner ovulates, there’s chance they may get pregnant.
Can a 7 year old get pregnant?
A woman becomes able to get pregnant when she ovulates for the first time — about 14 days before her first menstrual period. This happens to some women as early as when they are eight years old, or even earlier.
How do I tell my 6 year old I'm pregnant?
When you’re ready to tell your child about the pregnancy, keep the language positive, simple, and straightforward. For example, “Right now, there’s a baby growing in Mommy’s tummy. You are going to have a little sister (or brother) next spring.”

Ans- The process by which living things produce new individuals of their own kind is called reproduction.
What is pollination Class 12?
Pollination: It is the process of transfer of the pollen grains from the anther to the stigma of a flower. … There the pollen germinates and gives rise to the pollen tube, which grows down through the pistil toward one of the ovules in its base.
What does development mean in biology?
biological development, the progressive changes in size, shape, and function during the life of an organism by which its genetic potentials (genotype) are translated into functioning mature systems (phenotype).
