Biology- cell organelles assignment Animal cells: Introduction: An animal cell is called a eukaryotic cell; it has a cell membrane‚ cytoplasm and a nucleus. The cell surface is covered by a membrane only. The cell membrane is strong and keeps the cell together even though it is thin and flexible. The cell membrane also controls what goes in and out of the cell e.g. nutrients go in and waste comes out. The cytoplasm is inside the nucleus and it controls the cells activities. An animal is

DETAILED DIFFERENCES BETWEEN EUKARYOTIC AND PROKARYOTIC CELLS Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words‚ prokaryotes are primitive‚ simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes‚ which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and

The cell wall is the tough‚ flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. Just as the wall of the factory is for the factory. The wall also is the structure and strength. The cell membrane that separates the interior of all cells from the outside The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances

We all know that even though a cell is the basic unit of an organism it can be pretty complex inside of one. So why don’t we try and make it a little simpler by comparing it to something we’re all more comfortable with? Take Disneyland for example! Everyone is familiar with Disneyland and how it works. Let’s see just how similar these two can be. First‚ would be the entrance gate. The entrance gate could be our cytoplasm. Cytoplasm is the jelly-like fluid that fills a cell and inside is all the

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS All mammalian cells are eukaryotic‚ and whilst the eukaryotic type of cell is not exclusive to mammals‚ mammalian cells differ from other eukaryotic cells because of the organelles that are or are not present. For instance some plant cells have chloroplasts which are not present in mammalian cells‚ but both plant cells and mammalian cells are eukaryotic in nature. The term eukaryotic refers

Cell Organelle Worksheet Organelle Nucleus Where found (plant/animal/both) In animals it’s in the center of the cell while in plants it’s found in the cytoplasm. What it does in the cell (functions) It maintains the integrity of the genes and controls the activities of the cell. Something that performs the same function in the “real world” It works like a CPU sending out messages. Organelle Nucleolus Where found (plant/animal/both) For both animal and plants it’s within the nucleus of the

between the structure and function of four specialised human cells. The human body is made up of trillions of different cells; all play a huge role in the running and function of the body. They are the foundation of all living things. Each different cell has its own exclusive job. Without cells the human body would simply fail. All cells contain organelles which are the structures of the cells itself‚ organelles have individual functions. This essay will investigate the structure and function
