Germ celltumors(GCTs) are a neoplasm, or an abnormal growth of cells resulting in a mass of tissue, that are derived from the germ cells, the precursors of the gametes or sex cells, namely eggs andsperm. GCTs most often arise in theovariesor testes, known collectively as the gonads, ...
The G1, S and G2phases are collectively termed interphase. The rest of the cell cycle is concerned with cell division – mitosis in somatic cells, meiosis in the specialized cells of gonads. The stages of mitosis and meiosis are collectively called the M phase, potentially introducing confusion...
A stamen is the male part of a flower, and together all stamens form the inner third whorl of a flower structure called theandroecium. Each stamen comprises a long tubular filament with a sac called theantherat the top.Pollengrains contain male reproductive cells or malegametesand are produc...
What are gonads and gametes in human reproductive system? Egg and sperm cells are both a) Gametes b) Somatic c) Diploid d) Both a and c How does the female gamete move from the ovary to the uterus? Name the technique(s) which is(are) employed in the following scenario: Embry...
The largest dividing cells: are they alike? Joseph Frankel 'Physical extremes, in this case a very large cytoplasm, are always interesting in biology'[97] How can we frame a useful inquiry about the upper limits of cell size? If one asks which cell is the largest, one comes up with a...
are not corrected in the somatic cells, it may leads to the development of cancer or it results in the loss of function of genes. More than that, if DNA damages occur in the gametes is not rectified, it will be carried over to next generation through progenies. Thus, damage to the ...
