4.7C: Comparing Plant and Animal Cells
Animal cells usually have an irregular shape, and plant cells usually have a regular shape. Cells are made up of different parts. It is easier to describe these parts by using diagrams:. Animal cells and plant cells both contain:. Plant cells also contain these parts, which are not found in animal cells:.
Although they are both eukaryotic cells, there are unique structural differences between animal and plant cells. Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells. While both animal and plant cells have microtubule organizing centers MTOCs , animal cells also have centrioles associated with the MTOC: a complex called the centrosome. Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not. The centrosome is a microtubule-organizing center found near the nuclei of animal cells. It contains a pair of centrioles, two structures that lie perpendicular to each other.

Plant Anatomy pp Cite as. The cells of plants possess a variety of included structures; some of which are similar to eukaryotic animal cells, but others are quite distinctive. Many can be observed with a compound light microscope, but others are only resolved with the aid of electron microscopy. One of the great biological achievements of the recent twentieth century has been the development of electron microscopes, the appropriate specimen preparation for observations, and the determination of the structural, genetic, physiological and the elucidation of the role of microscopic and ultrastructural components. This chapter will describe the structure and function of cellular organelles and their respective roles in plant anatomy.
Many plant cell organelles are also found in animal cells.
Organelles make up the subunits of a cell. There are numerous each with their own function. The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell. As such, it is actively involved in such both passive and active transportation to and from the cell.
ТРАНСТЕКСТ еще никогда не сталкивался с шифром, который не мог бы взломать менее чем за один час. Обычно же открытый текст поступал на принтер Стратмора за считанные минуты. Она взглянула на скоростное печатное устройство позади письменного стола шефа. В нем ничего не .
Да, да, прямо. К тому же у нас вышел из строя генератор.
