To investigate the effect of phosphate on cell division in root tips.

Planning Exercise Aim To investigate the effect of phosphate on cell constituent in stemma tips. Background knowledge phosphate ions (macronutrients) thermonuclear number 18 all important(p) large amounts by plants. They be required for root growth. For the root tips cells to divide, mitosis has to occur. orthophosphate is needed for work of ATP which provides energy for mitosis to occur. desoxyribonucleic acerb replication occurs during interphase of the cell cycle. desoxyribonucleic acid is do up of newton containing base, pentose scratch line and phosphate group. The phosphate group forms part of the sugar phosphate backbone of desoxyribonucleic acid. Phosphate is thitherfore necessary in DNA replication. During root growth, membranes in addition grow and they argon made of phospholipids bi-layer which contains phosphates. Therefore, phosphates atomic number 18 needed their membranes to grow. Mitosis is the process in which a eucaryotic cells nucleus divides into two resembling fille nuclei. There are five dresss in mitosis. 1. Interphase, in this do the DNA in the nucleus replicates. Therefore, the chromosomes d intumesce of two same chromatids each. However, they are in obvious. 2. Prophase, in this stage chromosome belongs obvious as they become shorter and thicker. Replicated centrioles run for opposite poles of nucleus and a arbour is formed. atomic gasbag and nucleolus disappear. Chromosomes become visible and the two chromatids are attach to each other at centromere. 3.

Metaphase, in this stage chromosomes are attached to mandrel by centromeres and line up crossways the equator. Chromosome separates at the centromere and the chromatids are pulled apart. 4. Anaphase, in this stage, chromatids are pulled by the microtubules and move to opposite poles. 5. Telophase, in this stage, chromatids reach the poles of the spindle and nuclear envelope reforms as well as nucleolus. The spindle ultimately disappears. Nucleoli reappear. Mitosis is completed. Hypothesis My hypothesis is that as there is more intentness of phosphate, the... If you regard to get a broad(a) essay, order it on our website: Orderessay
