Gregor Mendel lived in an Austrian monastery and tended the monastery garden. In 1865, through his observations of the garden pea plants that grew there, Mendel developed three basic principles that—although ignored at the time by his scientific colleagues—would later become the foundation for the new science of genetics.Every pea plant contains both male and female reproductive parts and will normally reproduce through self-pollination.
<span>Everyone has cells because these are the building
blocks of life. These tiny particles that clump into groups that form tissues,
organs, and organ systems are
what makes organisms distinct from non-living things that exist on Earth. Where
there are cells, life is present, and in its absence life cannot exist as we
know of today. Cells are responsible for bringing different species of
organisms that are found in different ecosystems all over Earth. They are tiny
but in groups they are responsible for every living organisms that have existed
through time. </span>

Sensory neurons <span>carry information to the brain, and motor neurons relay information from the brain to the muscles.
