Cytoplasm

divides it occurs in two steps: mitosis and cytokinesis. During mitosis, the nuclear membrane breaks down and reforms. The chromosomes also separate to where each daughter cell receives a diploid number of chromosomes. Cytokinesis is the division of cytoplasm that results in…

microscope. It might be better to use a light microscope if you are viewing a live specimen and do not want to kill it. 2. Prokaryotic cells are small, simple, no nucleus, no membrane-bound organelles, single loop of DNA (nucleosome), no cellulose, cytoplasm, cell membrane, cell wall (made of carbs), sometimes have cilia or flagella (movement). Eukaryotic Cells are larger cells, complex, with nucleus, membrane bound organelles, DNA tightly wrapped around histone proteins in chromosomes,…

eukaryotes. The prokaryotic is the simpler of the two and are the one-celled organisms such as bacteria and archaea. The interior of a prokaryotic cell consists of a main nucleoid, which contains the DNA, the ribosomes, which synthesize proteins, and the cytoplasm, which is a liquid cytosol that suspends the organelles. The cell is surrounded by a plasma membrane, which facilitates what enters or leaves the cell, a cell wall, which gives rigidity…

that float free in the cytoplasm or it is usually attached to the rough endoplasmic reticulum (ER). It is made of RNA, protein and is site for protein synthesis. Vesicles Vacuole is a small fluid filled sac present in the cytoplasm and it is always surrounded by a membrane. It transports substance in and out of the cell through plasma membrane. Some vacuoles are formed by Golgi apparatus and ER, while others are formed at the cell surface. Cytoplasm The Cytoplasm is a jelly- like…

In this stage numerous reactions can occur in the cell’s cytoplasm, and glycolysis will then take the molecule and break it down. The stage of cellular respiration is Krebs cycle, this cycle happens in mitochondria in eukaryotes and also in cytoplasm in prokaryotes. There are many steps to this cycle however enzymes, and catalysts have a big role in individual reactions. The pyruvic acid in created by…

B) Compare & contrast: Plant & Animal cells. Although plant and animal cells contain numerous similarities, they also feature prevalent significant differences. Animal and plant cells not only have functional differences but also have structural differences. Plant and animal cells both have a nucleus which is the control centre of the cell, it controls how the cell develops and how it reproduces. DNA is the genetic makeup of a cell, organ and body systems, the DNA in a cell is held and…

cells may exist which have capacity to recirculate widely through the lymphoid system. The stem cell (hemocytoblast) gives rise to cells that undergo several mitotic divisions together with cytoplasmic division to produce the megakaryocytes. The cytoplasm of the megakaryocyte becomes compartmentalised by membranes. The plasma membrane the fragments, freeing the…

acid. When the mRNA leaves the nucleus and enters the cytoplasm, the codons in mRNA are recognized by the anticodons in tRNA. Anticodons are a three nucleotide sequence that is complementary to the codons in the mRNA. The tRNA is a complex that has an amino acid at one end and an anticodon recognized by the codon in mRNA at the other end. Translation occurs in three steps and takes place on a ribosome. The ribosomes are found in the cytoplasm, they have a large and small subunit, and a E, P and…

Cycle and The Electron Transport chain. Glycolysis is the first step to cellular respiration. There are 2 stages that make Glycolysis happen. The first is the “Investment” stage. As you consume food, glucose is consumed and passed through the cytoplasm. In order for the investment stage to begin, you need to use energy to start it. Unlike the other two processes, Glycolysis does not need Oxygen to function. The only form of energy our bodies can process is ATPs, which stands for Adenosine…
