<span>A cell is the most basic form of
life. It is what most of the organisms are made off. For the organism to
function, the cell must also function. It has organelles too that helps
functions what the microorganisms need. A leaf cell contains chloroplasts that
animal cells and animal cells do not have.
The chloroplast is where the photosynthesis happens. It needs sunlight
for the process of photosynthesis. Notice that the leaf has a broader surface
area to enable them to be exposed to the sun.</span>
A chromosome is made of both one DNA molecule wound around small protein molecules whereas DNA is just one large molecule called deoxyribose nucleic acid.
A non random influence affecting who survives or reproduces
is selective pressure. A selective pressure is considered to be a phenomenon in
which behaviors of the living organisms are being driven to evolution and the
natural selection in which they are also divided in to two types.
