Animal Cell

Animal Cell Definition: Animal cells, which are the fundamental units of life in the Animal Kingdom, are eukaryotic cells. This means that they contain a true (membrane-bound nucleus) along with other membrane-bound organelles. All these work together to perform specific functions that are needed for the proper functioning of the cell. Although plant cells are … Read more


Phospholipid Definition In simple terms, the phospholipid can be called as one of the primary components of the cell membrane. In the cell membrane, these phospholipids will be organized into a “bilayer”, thereby, acting as the framework of the cell in which the other components of the cell membrane will be embedded. As the name … Read more

Central Vacuole

Central Vacuole Definition To put it simply, the central vacuole is membrane-bound organelle that can be seen in the cells of the following organisms: Plants Fungi Protists Animals Bacteria Until recently, it has been believed that all the vacuoles that are present in all these types of cells have a common origin. But, the recent … Read more

Plant Cell

Plant Cell Definition Plant cells, which are the fundamental units of the members of the plant kingdom, are eukaryotic cells. This means that they are having a true (membrane-bound) nucleus in them. In addition to the nucleus that is enveloped by a membrane, the plant cells are also containing other organelles. Here, the organelles can … Read more
