Cells are created from existing cells is the part of the
cell theory which explains why the skin is able to repair itself. The body
produces 300 million new cells every day. After getting a cut or scratch, the
skin may start bleeding. This happens when the injury tears down the tiny blood
vessels that is found under the skin’s surface. The body wants to stop the
bleeding so the platelets will come to the rescue.
At the cut, platelets stick together. This is how the blood
clots which then become a scab. This protects the area so the cells underneath
it can have the time to heal. Beneath the scab, new skin cells multiply to
repair the wound. Damaged blood vessels are restored and blood cells end the infection
in the wound. And also, under the scab, a new skin layer is formed.
Answer:
Generally in non flowering plant the male sex organ is called the antheridium,while the female is called the achegonium. Due to the habitat and methods of reproduction, special adaptive feature s have been developed by these plants to ensure reproduction and prevent extinction.
Explanation:
Based on structure,Antheridial (male sex cells) are usually upright in position,with pores located at the top of the antherialdial disk.These perforation is adaptive feature for effective dispersal of sperm during reproduction.
In addition present in the archegoniu is the achegonium dsik. The latter is the adaptive feature for protection of the archegonia.The disc serve as an umbrella surface for the protection of the archegonia during reproduction.Thus ovum is well protected to ensure fertilization and prevent wastage.
