  • Male Reproduction System

    Male Reproduction System consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female’s body; the fertilized ovum (zygote) develops into a fetus, which is later […]

  • Transpiration

    Transpiration is the process in which plants release the water inside it in the form of moisture or water vapor. Parts of plants like stems, small pores on leaves, flowers evaporates the water to the atmosphere. Basically, It is the process in which water is evaporated in the atmosphere from plant leaves and other parts. […]
