Cell division

They are unicellular organisms from the kingdom Protista. They move by a flagellum, which is located in the anterior end. They also contain a red eyespot at the anterior end that is able to detect light. Since Euglena lack a cell wall, they contain a pellicle composed of a protein layer. They usually live in quiet puddles or ponds. They have chloroplast that traps sunlight which is used for the process known as photosynthesis. Since Euglena can absorb food from their environment…

were at one point in evolution, prokaryotic cells. It is said that before they had the function and job that they have today, that the mitochondria and the chloroplasts lived on their own and commonly took shelter inside of larger host cells. There they provided the host cell with the nutrients that it needed to live, and in return the host cell gave the cells a protected place to live. Eventually the host cell, the mitochondria, and chloroplast cells became dependent on each other for survival.…

yet, but they are getting closer to cloning humans year after year. Scientists have already cloned human stem cells in 2013 by Shoukhrat Mitalipov and his team at Oregon National Primate Research Center. From a technical perspective, cloning humans and other primates is more difficult than in other mammals. It is more challenging because the cells require proteins essential to cell division. Also, multiple copies of an ancestor’s genes might bring several surprises. When critics say human…

to change into these protective suits so we would be kept safe from any harmful substances. We were all told that we would be put into two groups the A and the B group. We would all be put into a Eukaryotic Cell if the machine worked to get a closer look at the organelles in a Eukaryotic Cell. I was put into the A group along with another girl who looked about 16. The B group had a boy who looked about 14 and a girl who looked about 15. I guess the age varied between all of us because I am 17.…

Cells have specific structures within them that allow them to carry out their functions; these structures are called organelles. Organelles have different functions within a cell that is called Division of Labor. They are also classified in two different groups, membranous and non-membranous. Membranous organelles are surrounded by a membrane while of course, non-membranous are not surrounded by a membrane. When describing the organelles and their function, first will be the membranous…

1. a) The three parts of a nucleotide are phosphate, nitrogen-containing base, and the deoxyribose sugar. b) Deoxyribose sugar is the sugar that is found in a nucleotide. c) The nitrogen-containing base is the nucleotide component that contains nitrogen. d) The four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine. 2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and…

sperm by a cortical granule reaction, specifically by raising of the vitelline envelope. There are thousands of granules beneath the cell membrane that are similar to the granules in the acrosome of sperm. They will fuse with the membrane when Ca2+ is released from the ER within the egg. This fusion will then cause an exocytosis of the granules’ contents between the cell membrane and the vitelline envelope. An enzyme, cortical granule serine protease, is included in the released contents and it…

P5 List of all cell features and functions: • Nucleus • Cytoplasm • Cell membrane • Mitochondria • Ribosomes • Cell wall (Plant Cell) • Endoplasmic Reticulum (smooth & rough) • Lysosome • Golgi Apparatus/body • Nucleolus • Vesicles A nucleus is like the brain of the cell, it is a large oval which controls the activities of the cell and the nucleus also contains genetic material (DNA). The nucleus also contains hereditary information. Most chemical processes and reactions, which are…

Thanks to modern medicine and scientific research, cloning is a reality and no longer science fiction. We may great advancements to Sam cell research as well, leading to cures for diseases. All of this is very different though from what Victor Frankenstein tried when he built the monster. I will first speak on cloning and all the details having to do with it. Clones are living beings that are correct hereditary duplicates. Each and every piece of their DNA is indistinguishable. Clones can…

consists of 2 complementary strands in a helical structure where each strand serves as an informational template for the offspring during duplication (Rafael, 2010). An organism is made up of a vast collection of cells where each cell originates from a parent cell (Rafael, 2010). The cells require a way in which they can transfer and copy their genetic information efficiently (Bagley, 2013). The organism…
