Important Processes of Reproduction
When both the ovaries are fully mature, they alternatively produce ova at the interval of 28 days. Release of ovum into the uterus through the fallopian tube is called as ovulation.

In human beings reproduction takes place through the activities of male and female reproductive organs. To understand this, it is essential to study the structure of male and female reproductive systems separately.
What is the importance of DNA copying in reproduction?
Two organisms- male and female are essential for sexual reproduction. Now let us study some basic methods of reproduction in single organisms.
Living beings develop their population through reproduction. But reproduction is the process through which different traits appear in living beings. Variation is essential for evolution
Flowers are most beautiful and attractive parts of a plant. These contain reproductive structures- male and female. Flowers containing any one of these structures are known as unisexual whereas flowers containing both the reproductive structures are known as bisexual.
Growth of human population, fast but unplanned industrialization and irresponsible behavior to environment are causing imbalances in the local, regional, national and global environment. These are causing not only local but global problems in the environment.
The scarcity of oxygen and the need of producing more and more oxygen! We may think for sometime about it. But, anyone knows that life is not possible without it.
Most of the animals have a network of very fine filamentous or threadlike structures which exchanges information. These structures are called as nerves.
Conservation of species in their natural habitats- in areas where they occur under normal conditions is called in-situ conservation.
This type of conservation strategy protects the entire area. Such an area is protected and maintained to conserve all the known or unknown species inhabiting it.
In this type of conservation, species are not isolated or provided with health care, food, or mating facilities. Only factors detrimental to species’ existence and development are eliminated in this conservation strategy. Human interference, such as hunting, cutting down trees, collecting firewood, etc., is completely banned in such areas.
Thus, diversity of food is in fact the diversity of culture or at least you can say that cultural diversity of India is linked to its biodiversity. And so, the cultural diversity of the world is linked to its biodiversity. But often, we don’t get ready to accept it.
Ever since the earth was inhabited, humans and other life forms have depended on things that exist freely in nature to survive. These things include water (seas and fresh water), land, soils, rocks, forests (vegetation), animals (including fish), fossil fuels and minerals. They are called Natural Resources and are the basis of life on earth.
