Answer:
During the creation of oocyte, 3 additional haploid cells are created that will not be fertilized these cells are called Polar bodies.
Explanation:
The process of formation of oocyte is known as the Oogenesis. The oogenesis is the formation of oocyte which is capable of being fertilized, and the process begins even before the birth of the child. The oogonia is a diploid cell which undergoes mitosis to form the primary oocyte.
The primary oocyte then undergoes first meiotic division forming the secondary oocyte. this secondary oocyte is haploid in nature and this would again undergo another meiotic division to produce 4 haploid daughter cells. One of these is haploid ovum with additional 3 cells which do not get fertilized. these additional haploid daughter oocyte cells are Polar bodies.
Pick a point on the graph-
Mass= 24 and volume =4
Density = mass/ volume
Density = 24/4 = 6
Answer:
c. They usually have certain special functions.
Explanation:
Multicellular organisms have more than one cell in their body. They exhibit division of labor. This means that various cells of multicellular organisms are differentiated to perform specific functions. Therefore, there are different types of cells in the bodies of multicellular organisms that differ from each other with respect to structure and functions. For example, the cells of root hairs in plants perform the function of absorption of water from the soil while the mesophyll cells of their leaves perform the function of photosynthesis.
