Summary
Peroxisome is a structure present in the all
eukaryotic
cells
and
are
about
the
size
of
lysosomes (0.5-1.5 µm). peroxisomes are present
near the liver and kidney in animals and in plants
they assist photosynthesis. Peroxisomes helps in
removing of the H2O2 from the cell by the the
enzymes present in them. Any disorder in the
peroxisome swill lead to some disorders like Xlinked
adrenoleukodystrophy (X-ALD)
and
Zellweger syndrome.
A small, spherical, membrane-bound organelle
containing a fluid with dissolved molecules. In
plant cells, the vacuole takes up a large amount of
space, at times, it occupies more than 90% of the
plant cell space. It is said that vacuoles are usually
formed by the fusion of many membrane vesicles.
Due to this reason, a vacuole does not have any
specific size or shape. However, when it comes to
the vacuole structure, it is designed so as to
complement its function. Many mature and grown
plant cells usually have a single large vacuole. This
vacuole is surrounded by a structure known as a
tonoplast. The vacuole contains a fluid known as
cell sap. This fluid or cell sap contains different
compounds, some of which are secretory and
some are excretory in nature. Also the vacuole
contains various concentrations of salts, sugars
and different kinds of soluble pigments. The cell
sap also contains various enzymes that are even
capable of digesting the cell itself. Although most
mature plant cells contain a large single vacuole.
This eventually pushes the cytoplasm, nucleus and
other
such
structures
against
membrane and the cell wall.
