Biology Inheritance – Mitotic Squash of Garlic Root Tip Mitosis is the process of cell division; it is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. It is generally followed immediately by cytokinesis‚ which divides the nuclei‚ cytoplasm‚ organelles and cell membrane into two cells containing roughly equal shares of these cellular components. Mitosis and cytokinesis together define the mitotic phase of the cell cycle—the

USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS Introduction The zone of cell division on the onion root tip is a great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually

Biology Experiment Absorbance of Beet Root Sarah Hsu Y 11 Hope Purpose The beetroot experiment is to investigate and understand the affect different temperatures have on cell membrane structures. Hypothesis The higher the temperature is‚ the higher the rate of absorbance of the cell membrane will be. Variables Controlled Variables | Independent Variables | Dependent Variables | The length of the beetroot placed into the test tube. | The temperature of the water bath. | The absorbance

MATERIALS • compound light microscope • prepared slides (longitudinal sections of onion or garlic root tips) • prepared slides (whitefish blastula or other animal tissue) Procedure PART 1: MITOSIS IN PLANT CELLS 1. Observe a prepared slide of a longitudinal section of onion or garlic root tips. Use low power to locate the region of actively dividing cells near the end of the root. Using high power‚ examine individual cells in the region. Find a cell from each stage of mitosis‚ using

molecules present. This will therefore make the experiment unfair‚ because the more pigment molecules present the more pigment molecules that can move out of the cell. Therefore the beetroot used should be freshly cut. pH The pH is also an important factor‚ as pH can have an effect on the weak interactions and bonds that bound the membrane together. To keep the pH constant it is important to make sure that the same surrounding are used for the experiment. Surface area. The surface area of the beta

was the game of Squash. I had no knowledge of squash before other than seeing it on television. It is a game that I believed was only played by persons who were better off in society (Rich)‚ but to my surprise it was not so. Squash is a game for all ages and levels of ability‚ even if you have not seriously played a “racket sport” before you will find it reasonably easy to master the basics and have an enjoyable workout with an opponent. Expectations My expectation for squash was quite normal

Cucurbita morschata better know as butternut squash belongs to the Cucurbitaceae moschata family of field pumpkins; originating from Central America region (Brown‚Klaire).The Native Americans believed the squash to be holy and buried it with their loved ones. They also believed the squashes seeds to increase fertility and were planted close to homes. Externally‚ the squash is better described as large-sized fruit featuring thick neck attached to a pear-shaped bottom and has smooth‚ ribbed skin. However

principally in the roots‚ in the shoots and in the cambium. This experiment aims at observing cell multiplication in the root tip of a garlic root. Discussion The purpose of this practical was to observe and identify under the light microscope the stages of mitosis division (interphase‚ prophase‚ metaphase‚ anaphase‚ telophase) by using tissue from root tips. The root tips were prepared before it was view under the light microscope‚ hydrochloric acid was added to the root tips in order to destroy

Planning Exercise Aim To investigate the effect of phosphate on cell division in root tips. Background knowledge Phosphate ions (macronutrients) are needed 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. DNA replication occurs during interphase of the cell cycle. DNA is made up of nitrogen containing base‚ pentose sugar and phosphate group
