May 23, 2020 · Peroxisomes are oxidative membrane-bound organelles found in the cytoplasm of all eukaryotes. The name is accredited due to their hydrogen peroxide generating and removing activities. Structure. Peroxisome consists of a single membrane and granular matrix scattered in the cytoplasm.

Microbodies are single, membrane-bound, globular shaped organelles, which are found in the cytoplasm. They range in size from 0.5-1 micrometer, and contain degradative enzymes. Many kinds of microbodies are present in a plant cell, of which the two most common types are peroxisomes and glyoxysomes.

This membrane-bound structure is what is known as an organelle. The membrane that bounds the organelle is made from two layers of phospholipids. The function of this double layer is to insulate all the little compartments that are in every large cell. Prokaryotic cells do not have a membrane- bound nucleus or any other membrane-bound organelles. They are small (generally 0.5-10 µm) single cells (unicells). They are relatively basic cells and have very little cellular organization (their DNA, ribosomes, and enzymes are free floating within the cell cytoplasm).
single-membrane compartment eukaryotes Mitochondria and chloroplasts, which have double-membranes and their own DNA , are believed to have originated from incompletely consumed or invading prokaryotic organisms , which were adopted as a part of the invaded cell. Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. This means that they have no nucleus. Also, the genetic material, i.e. DNA, in prokaryotes is not bound within a nucleus. Additionally, the DNA is less structured and is in a single loop.
double line on electron micrographs. (In addition to the cell membrane, some eukaryotic cells, such as plant cells, also have a rigid cell wall surrounding the cell membrane. This serves a structural function. Nucleus The nucleus is a membrane-bound structure that contains the genetic material (deoxyribonucleic acid, or DNA) of eukaryotic cells.

The matrix also possesses single circular DNA molecule, a few RNA molecules, ribosomes (70S) and the components required for the synthesis of proteins. So, Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds (cristae) when viewed in cross-section. The cristae greatly increase the inner membrane's surface area.
Unlike prokaryotic cells, eukaryotic cells have: 1) a membrane-bound nucleus; 2) numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others; and 3) several, rod-shaped chromosomes.
