Explanation:
The Germ Theory of Disease indicates that microbes are the causal agents in human disease. In modern healthcare, Germ Theory has led to a breakthrough in the treatment of infectious diseases with antibiotics such as penicillin, and the prevention of disease outbreaks through proper sanitation and vaccination.
Further Explanation:
Biology's unifying principle states that cells are the basic units of biological organisms. Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.
Before the discovery of cells by Robert Hooke in 1665 with a simple microscope, many scientists had long believed that life rose spontaneously over extended periods of time. Circa 1668 Francesco Redi, challenged the idea of spontaneous generation of maggots from rotting meat by placing meat in various sealed open, partially sealed and sealed containers. Sealed containers did not show the presence of maggots, and he theorized that these were likely from eggs laid on the meat by flies. This was the development of the theory disproving abiogenesis (cells arise from other living cells); this eventually proved the unifying principle we know today.
Cell theory states that living things are comprised of cells, as their smallest units capable of functioning. Microscopy helps to prove this, as cells and their varying components can readily be seen, observed and later classified.

Answer: Stomata
Explanation:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters.
Fertility is the measure of the ability to become a parent.
<h3>FERTILITY:</h3>
Fertility is a phenomenon that describes the ability to reproduce or produce offsprings.
Reproduction is one of the characteristics of living things and the ability to successfully execute this characteristics is termed fertility.
The opposite of fertility is sterility, which means the inability to produce offspring or reproduce.
