Microtubule

Microfilaments look like thin solid rods that have a structural function. The microtubules carry functions such as transportation of granules, vesicles or organelles such as mitochondria as well as offering structural support to the cell. The mitochondria are essential organelles in all cells because it is a powerhouse for energy used…

While the animal cell has lysosomes, the plant cell has lytic vacuoles. They both do the same thing; they digest excess or worn out organelles and food particles. Even though the animal cell has microtubules, the plant cell has chloroplasts. The microtubules move around all of the organelles in a plant cell including mitochondria, like a conveyer belt. The chloroplasts use photosynthesis to make food, energy, and heat. The animal cell has centrioles, however, the plant cell…

I. The most basic unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells…

In G2 organelles replicate, and microtubules start to attach at the spindle. Also, chromosomes coil very tightly in G2. As you can see, the gap phase 2 was a pretty quick one for me. Interphase is done which means I will move on to the M…

formation of the spindles and therefore interrupt cell division. The drugs that harm the process of mitosis are represented by microtubule binding drugs that inhibit the function of the mitotic spindle in order to halt the cell cycle in mitosis and to induce apoptosis in tumor cells. Vincristine irreversibly binds to and stabilizes tubulin, thereby interrupting microtubule assembly/disassembly dynamics, thereby preventing the formation of the mitotic spindle and leading to cell cycle arrest in…

The chromosomes are then moved around by molecules called motor proteins. Two different proteins then pull the microtubules from one side to the other so that the chromosomes line up right down the middle at the equatorial plane. Once the chromosomes are in the middle, the pull from the proteins results in a split from the chromosomes’ copies. When the split occurs…

(the area surrounding the centrioles)? Is it necessary for mitosis? Defend your answer. Centrosome is the regions that responsible for formation of spindle fibers from the microtubules. These spindle fibers are needed for pulling the chromosomes apart from each others in anaphase. It is necessary for formation of the microtubules and without the centrosome, there will not be any separation of the chromosomes and genetic disorders will develop. 6. What are advantages of using onion roots for…

Alzheimer’s disease is the most common dementia in elderly presented in more than 5 million Americans. It is an irreversible and progressive brain disease that accounts for 60-80% of cases of dementia in the elderly. The symptoms can appear after the age of 60-65 to population over 85 years old. This disease slowly destroys memory and thinking skills, followed by failure of language skills, visual-spaced orientation, judgment and eventually even the ability to carry out the simplest tasks in a…

called the storma. Then finally suspended in the fluid is a network of membrane-enclosed disks and tubes. The disks occur in interconnected stacks called grana, which are the chloroplasts solar power packs. Cilia and flagella are made up of microtubules that are enclosed in an extension of a plasma membrane; cilia are short structures while flagella are long structures. A cell usually consists of one flagellum or two flagella, but a large number of cilia are present in a cell. They…
