CELL STRUCTURE AND FUNCTION - UK Essays A description of the functions of each cell and some of their individual using our Essay Writing Service! Essays; Sciences; Cell Structure And Function FREE Cell Structure and Function Essay - Example Essays Cell Structure and Function. A cell membrane is found in both plant and animal cells. It is a well known fact that cell is an integral part of any living body. But the structure and function of the cells are not alone controlled by the organelles present within it; rather it depends upon the membranes as well. Therefore, cell membranes are the part of any cell that divide the. Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles, but their functions are quite different. The purpose of vacuoles in a plant cell is to store water and maintain the structure of a cell, whereas in animal cells they are used to store water, waste, and ions.
Although plant and animal cells both have mitochondria, cytoplasm, and ribosomes they differ in many ways. Animal cells do not have a cell wall and are round with irregular shapes. Centrioles are also present in all animal cells, as well as most eukaryotic cells.
Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles, but their functions are quite different. The purpose of vacuoles in a plant cell is to store water and maintain the structure of a cell, whereas in animal cells they are used to store water, waste, and ions.
Animal cells have one or more small vacuoles, whereas plant cells have one, large central vacuole. Plant cells are the only type of cells that contain plastids which contain pigments that are used in the photosynthesis process. Both cells have an assortment of organelles, each with various functions that make life as we know it possible.
Which of the following structures are present in both prokaryotic and eukaryotic cells? Both types of cells are covered by a cell membrane and are made of the same basic chemicals: Ribosomes are responsible for the synthesis proteins and are also present in prokaryotic and eukaryotic cells.
Where is genetic material found in plant cells? DNA is the genetic material found in the nucleus of plant cells. Mitochondria contain their own separate DNA as well. Mitochondria are the only organelles that contain their own DNA circular and have a double membrane.
Why do you think this might be so? Mitochondria contains circular DNA. This type of DNA is typically found in viruses and bacteria. Bacteria were present billions of years before the first eukaryotes appears. Because of their ancient origins it is argued that mitochondria originated as bacteria.
The mitochondria then invaded or was consumed by another prokaryotic cell.
Over the course of millions of years mitochondria lost the ability to function independently and became a permanent part of the eukaryotic cell. Although the mitochondria became a part of the cell, it retained some of its original DNA. Where else do we see circular DNA?CELL STRUCTURE AND FUNCTION All living things are made of the same basic building blocks, cells.
