Eukaryote

This could also lead to evolution, survival of the fittest, overpopulation and the extinction of others. Limiting factors can be many things like space, food, light and many other things. For Sunflowers and example that would lead to carrying capacity would be if all the organisms that consumed or killed the plant would be removed from its environment by an invasive species or environmental changes, then the Sunflowers would grow faster and closer to each other. This would cause space, water,…

Purpose: Meiosis is the process by which cell division results in the production of new cells containing half the number of chromosomes of the original cell. These cells are recognized as gametes and can recombine in order to create a zygote during fertilization. The purpose of this assessment is to demonstrate a clear understanding of the reproductive process and fertilization, through the presentation of a flow chart of this process in mythical dragons. Method: Step 1) Creative title Step 2)…

Eukaryotic cells are known for its organelles variety. Each organelle has its function so consequently each organelle differentiates from one another by its content. In this lab, the cells from a cauliflower were studied with the purpose to separate nuclei and mitochondria content from a solution. To achieve the results, the cauliflower solution had to go through differential centrifugation, microscopy, and succinate dehydrogenase assay. For the fist part of the lab density played a key role in…

Planaria Regeneration and Development Lab 5 Name: Dominic Siaw TA: Marian Wahl Date Performed: 3/31/15 Date Submitted: 4/14/15 Abstract The purposes of this experiment are to become familiar with the anatomy and behavior of Planaria and make a design to test which aspect of diffusion gradient model which will cause development. The body parts of planaria was observed under a microscope. The flatworms were cut into 3 parts equally based on the gradient…

Organelles work together to maintain a cell's internal process and functions by providing the necessary needs for the cell. Although this mainly applies to Eukaryotic cells, this can also apply to Prokaryotic cells. Prokaryotic cells perform some of these function, but in a simpler way. Organelles work together to protect the cell, provide energy, repair the cell, direct the cell, and clean up the cell. First, organelles work together to protect the cell. The cell membrane is the main organelle…

1. What are the various phases that make up the cell cycle? Explain what happens during each phase. (4 marks) The cell cycle consists of many stages, which are separated into two phases: interphase and mitosis. During interphase, the cell grows larger and makes a copy of its own DNA. Interphase occurs for about 90% of the cell cycle and consists of the following stages: G1 phase, during which the cell grows larger and produces more of its organelles, proteins, and ribosomes. This phase ensures…

Protein work “the collection of proteins within a cell determines its health and function Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance. Proteins also receive signals from outside the cell and mobilize intracellular response. They are the workhorse macromolecules of the cell and are as diverse as the functions they serve. Proteins can be big or small, mostly…

The moss Physcomitrella patens is an attractive model system for plant biology and functional genome analysis.(1-7) It shares many biological features with higher plants (vascular plants) but has the unique advantage of an efficient homologous recombination system for its nuclear DNA.(2,3) This allows precise genetic manipulations and targeted knockouts to study gene function, an approach that due to the very low frequency of targeted recombination events is not routinely possible in any higher…

Structure Mitochondria are small membrane-bound organelles that are usually about 1 – 10 microns in length. They can be spherical or rod-shaped. The mitochondrion is enclosed by two membranes that separate it from the cytosol and the rest of the cell components. The membranes are lipid bilayers with proteins embedded within the layers. The inner membrane is folded to form cristae; this increases the surface area of the membrane and maximizes cellular respiration output. The region between the…

The reason TYMC is such a crucial factor is because mold and yeast are considered members of the fungus family. It can be found all throughout nature, in air, soil, water, vegetation and decay. It can grow and thrive in a wide range of temperatures and pH environments, even in harsh conditions that bacteria would not be able to survive in. Unlike plants, they do not produce their own food source. Their means of survival consists of breaking down matter from their immediate environment into…
