When the intestines do not return from the umbilical cord, this is what causes an Omphalocele. The omphalocele will not have skin on top of it, only the umbilical membrane. An umbilical herniation is a weakening of the muscles/fascia around the umbilicus and protrudes tissue/organs through that area.Skin will be covering the herniation.t is not covered w/skin. An umbilical hernia may present itself @ birth, but you're more likely to see it later in infancy, childhood, or (if female) not even til pregnancy--it's actually sort of an umbilical rupture then. Skin does cover the defect, and it is no where near as large as an omphalocele.
Plant cells do not have centrioles. Hence, the structure of the poles is different to that of the cells that possess centrioles. The poles of the cells of plants are broader when compared to the cells of animals. This is probably because of the absence of a cellular organelle that is defined to act as a f ocal point.
A plant cell also contains structures not found in an animal cell. Some of these include a cell wall, a large vacuole, and plastids. Plastids, such as chloroplasts, assist in storing and harvesting needed substances for the plant.Animal cells also contain structures such as centrioles, lysosomes, and cilia and flagella that are not typically found in plant cells.lant cells are eukaryotic cells, or cells with a membrane-bound nucleus. Unlike prokaryotic cells, the DNA in a plant cell is housed within the nucleus.
