Why not test yourself with our quick 20 question quiz, The cells of animals are advanced and complex. A large number of specialised cells together make up tissues and various tissues together make up an organ. Now we have established the general features of both animal and plant cells we must also remember that many cells do look different and this is because they have their own special jobs to do. The acrosome in the head contains enzymes so that a sperm can penetrate an egg. Ribosomes are involved in the process of creating proteins. ✕FREE Animal Cells fact sheet Enter your details to receive our fact sheet on animal cellsNice! The middle piece is packed with mitochondria to release energy needed to swim and fertilise the egg. Some specialised cells in animals that you should know: Muscle Cell; Nerve Cell There was an error submitting your subscription. Cilia on the surface beat to move fluids and particles up the trachea. For this task we are going to use a … Examples include nerve cells, muscle cells and red blood cells. Three types of blood cells exist in our circulatory system: red blood cells, white blood cells, and platelets. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system. Epidermis. These small organelles perform a number of functions regarding the digestion of compounds such as fats, amino acids, and sugars. Muscle Cells. The nucleolus is the center core of the nucleus and produces organelles called ribosomes. Keratinocytes make up around 90% of all skin cells and produce a protein called ‘keratin’. The cytoplasm contains nutrients for the growth of the early embryo. The aim is to explain how cells are organized in multicellular organisms to form tissues and organs. Specialised cells: A specialised cell is when a cell has certain features that make it very good at its job. Melanocytes sit underneath keratinocytes in a lower layer of skin cells and the melanin they produce is transported up to the surface layers of cells. The specialized cells can perform a certain function within the body. Please try again. Biology. Specific Function: Contain haemoglobin which transports oxygen to other cells and around the body. N.p., 2017. This is world’s #1 textbook for beginning biologists and has been hugely valuable to me over the years. Red Blood Cell 2. Specialized Cells, Biology 1.
