How is a sperm cell Specialised?
Sperm Cells are specialised in a number of ways. They have an Undulipodium (tail) which moves by energy generated by many mitochondria and propels the cell. The head of the cell contains an Acrosome, which is a specialised Lysosome that releases enzymes so that the Sperm Cell can penetrate the Ovum Coat of the Egg.
What does it mean if a cell is Specialised?
Specialised cells are cells that have developed certain characteristics to perform a particular function. Example: Red blood cells (rbcs). Function – Red blood cells carry oxygen around the body when it is bound to a protein called haemoglobin.
What is a disadvantage of cell specialization?
What is the disadvantage to cell specialization? A cell that only has to do one function can be much more efficient at that job. The cells are dependent upon one another. If one group of cells fails to do its job, the other cells will perish.
What is indefinite cell division?
Cells which can divide indefinitely are termed immortal. Outside of cell biology, senescence refers to the aging process.
What is cell specialization and why is it important to multicellular organisms?
Cell specialization ensures that there is no conflict in functioning of cells to perform a specific task. The specialisation process ensures an effective use of energy by the cells.
Why do cells have to undergo cell division?
It is important for cells to divide so you can grow and so your cuts heal. It is also important for cells to stop dividing at the right time. If a cell can not stop dividing when it is supposed to stop, this can lead to a disease called cancer. Some cells, like skin cells, are constantly dividing.
What are the most important structures in the cell during cell division?
Recall the cellular structures called centrioles that serve as origin points from which microtubules extend. These tiny structures also play a very important role during mitosis. A centrosome is a pair of centrioles together.
Which type of cell division is required for growth and repair of body?
meiosis
