1. Distinguish between somatic and reproductive cell division and explain the importance of each.
Cell division between somatic cells, which is also known as MITOSIS, is the process wherein non sex cells are reproduced. The main purpose of this process is for the regeneration of damaged tissues and cells such as wounds and scars. Mitosis consists of 5 phases, which are prophase, metaphase, anaphase, telophase, and cytokinesis.
Cell division between reproductive cells on the other hand, is commonly referred to as MEIOSIS. This is the process of reproducing gametes, or sex cells in the gonads. Meiosis has three different parts with several phases in each. First is interphase, which is where the cells prepare for the process, MEIOSIS 1 (prophase 1, metaphase 1, anaphase 1, telophase 1, cytokinesis), and MEIOSIS 2 (prophase 2, metaphase 2, anaphase 2, telophase 2, cytokinesis).
2. What is the significance of interphase?
Interphase is significant because this is the phase wherein cells prepare themselves for the actual process of cell division. Without interphase, cells would not divide properly. Interphase refers to the processes such as: G1, wherein cells increase in size, organelles and cytoplasmic components replicate. S, where DNA replication is present and produces 2 sister chromatids. Lastly, G2, where enzymes are produced and cytoplasmic materials are assembled.
