The Structures Within An Animal Cell

First of all, the most important structure in the animal cell is the mitochondria. The mitochondria is the vital because it provides energy for the cell (Doc. 2). For example, without the mitochondria, organelles would function slowly because the cell has no energy (OI). In Document 3, it states “Breaking down the food and releasing’ energy” (Doc. 3). “The mitochondria are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell” (OI). According to Ms. Quitmeyer, the mitochondria is crucial to the animal cell, and

The nucleus is a round, dense and the largest of the cells organelles, making it the easiest organelle to identify. The nucleus needs a protective membrane in order to keep the cytoplasm separate from the genetic material it holds.

The eukaryotes have organelles within them that are surrounded by membranes; each cell have a specific job to do within the area. The eukaryotic cell membrane have the same basic structure as the plasma membrane, which surround the cell, to do with the running of the cells and play many

One of the main manufacturing facilities within a cell. Consists of rough ER and smooth ER, they are physically connected but differ in structure. Consist of membrane-enclosed tubes and sacs within the cytoplasm. Rough ER, named for the ribosomes attached to its surface, make membrane and secretory proteins. One function of rough ER is to produce new membrane. Some products by rough ER are dispatched to other locations by transport vesicles.

Nucleus – The nucleus is the largest organelle in the cell. It acts as the control system for almost all the activities of the cell. It stores the cell 's hereditary material, or DNA

Numerous cells have little, finger-formed projections of the plasma film on their uncovered surfaces. These projections, called microvilli (solitary, microvillus), significantly increment the surface territory of the phone presented to the extracellular environment. Likewise, they cover the surfaces of cells that are effectively engrossing materials from the extracellular liquid, for example, the cells coating the stomach related tract. Microvilli have broad associations with the cytoskeleton. A center of small scale fibers hardens each microvillus and grapples it to the cytoskeleton at the terminal web.

Nearly all animal cells have a nucleus, with the only exception being the red blood cell. The nucleus has two major functions, which are housing the DNA and controlling the cell’s activities. In the centre of the nucleus is the nucleolus. This doesn’t have a membrane, but holds itself together. In the nucleolus, ribosomes are created through the mixture of RNA and proteins. These proteins are originally found in the cytoplasm, outside the nucleus, but they travel through the pores in the nuclear envelope, through the chromatin and into the nucleolus. The structure of the nucleolus allows easy

Which of the following structures is not normally found in the cytoplasm of a resting cell?

Rough ER - looks rough on the surface because it is stubbed with very small organelles called ribosomes. Ribosomes are made of RNA and protein and are the site of protein synthesis.

The rough endoplasmic reticulum is an organelle that plays a large role in synthesising and proteins. This is an important process called protein synthesis. (Plant Cell Anatomy, n.d.)

A vesicle is bubble like membranous structure that stores and transports cellular products and digests metabolic waste in a cell. (Biology Online, 2008)

There are a few organelles that exist in all three types of cells. The first of these is the cell membrane (also known as the plasma membrane). The plasma membrane is the outer boundary of the cell that protects the cell from its surroundings. It is selectively permeable because it controls what enters and exits the cell. Carl Naegeli and C. Cramer discovered the plasma membrane in 1855.

Students applying to the school is like the ribosomes of the school because they are the ones who pay for the school, get all of the sports awards, and get the school recognized for leadership awards.

Ribosomes are the structures in which proteins are made. Cells that are active in protein synthesis are often crowded with ribosomes. Ribosomes are composed of RNA and protein. Some ribosomes are attached to the membranes, and some are free in the cytoplasm. Ribosomes are among the smallest of organelles. They are no larger than 25 nanometers in diameter. A nanometer is equal to one billionth of a meter.

The cytoplasm is a semifluid in the plasma membrane. It is in all eukaryotic cells. In prokaryotes, this is where the chemical processes of the cell take place. In eukaryotic cells, this is where organelles perform their functions. Cellular respiration also takes place here. One of stages of cellular respiration is glycolysis. Glycolysis is when glucose breaks down to form two pyruvates and 4 ATP. Its net result of 2 ATP is important for another process called the Krebs Cycle. This process is important because it begins cellular respiration. The cytoplasm also gives the cell its shape; without it, the cell would be “deflated” and substances would not be able to move throughout the cell. Organelles would have difficulty functioning too. It has been misunderstood that organelles float freely in the cytoplasm even
