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

Planning Exercise Aim To investigate the effect of phosphate on cell region in chill out tips. play down knowledge phosphate ions (macronutrients) atomic number 18 inwrought large amounts by plants. They are required for root growth. For the root tips cells to divide, mitosis has to occur. Phosphate is needed for production of ATP which provides energy for mitosis to occur. desoxyribonucleic acrid replication occurs during interphase of the cell cycle. DNA is do up of nitrogen containing base, pentose scratching and phosphate group. The phosphate group forms part of the sugar phosphate backbone of DNA. Phosphate is therefore necessary in DNA replication. During root growth, membranes likewise grow and they are made of phospholipids bi-layer which contains phosphates. Therefore, phosphates are needed their membranes to grow. Mitosis is the sue in which a eukaryotic cells heart and soul divides into two resembling daughter nuclei. There are quintuple dresss in mitosis. 1. Interphase, in this do the DNA in the sum replicates. Therefore, the chromosomes consist of two same chromatids each. However, they are invisible. 2. Prophase, in this deliver chromosome belongs visible as they constrain shorter and thicker. Replicated centrioles move confrontation poles of nucleus and a arbour is formed. atomic envelope and nucleolus disappear. Chromosomes become visible and the two chromatids are attached to each some other at centromere. 3.

Metaphase, in this stage chromosomes are attached to spindle by centromeres and line up across the equator. Chromosome se parates 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 eventually disappears. Nucleoli reappear. Mitosis is completed. Hypothesis My hypothesis is that as there is more intentness of phosphate, the... If you want to hitch a full essay, order it on our website: BestEssayCheap.com
