Also, it controls the entry and exit of nutrients and other microscopic entities into the cell.
It is a double-membraned structure that surrounds the nucleus. It is an organelle that contains several other sub-organelles such as nucleolus, nucleosomes and chromatins. It is a small organelle found near to the nucleus which has a thick centre with radiating tubules.
A jelly-like material which contains all the cell organelles, enclosed within the cell membrane.
The substance found within the cell nucleus, contained by the nuclear membrane is called the nucleoplasm.
These cells differ in their shapes, sizes and their structure as they have to fulfil specific functions.
Plant cells and animal cells share some common features as both are eukaryotic cells.However, the major difference ends there as animals need to adapt to a more active and non-sedentary lifestyle.Furthermore, animals need to acquire their own food, therefore, they do not possess any of the specialized cell organelles such as chloroplasts.A typical animal cell comprises the following cell organelles: A thin semipermeable membrane layer of protein and fats surrounding the cell.Its primary role is to protect the cell from its surrounding.Furthermore, these cells exhibit the presence of DNA inside the nucleus.They also comprise of other organelles and cellular structures which carry out specific functions necessary for the cell to function properly.Animal cells are generally smaller than plant cells.Another defining characteristic is its irregular shape. But animal cells share other cellular organelles with plant cells as both have evolved from eukaryotic cells.As the name implies, an animal cell is a type of cell that is seen specifically in animal tissues.It is characterized by the absence of a cell wall, with cell organelles enclosed within the cell membrane.
