Organelle

In a cell there are many organelles to help keep the cell functioning. In the cell you could have a cell wall, cell membrane, ribosomes, cytoplasm, flagella, cilia, nucleus, nuclear membrane, nucleolus, chloroplast, Golgi apparatus, lysosomes, mitochondria, plastid, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, and a vesicle. Everyday items can represent many of the organelles. One example of this is by looking at a house. In a house you have a fence. The fence in your…

However, cells are split into two domains, those being Eukaryotes and Prokaryotes. Prokaryotes are all unicellular and are less advanced than eukaryotes; meaning that they lack a nucleus and only have a nucleoid region. They also lack membrane bound organelles. Prokaryotes are then broken into two kingdoms, Bacteria and Archaea. Bacteria are the less advanced of the two and is believed that Archaea advanced from Bacteria and then eukaryotic cells advanced from Archaea. Eukaryotic cells have a…

Camillo Golgi, an Italian scientist was the first to discover it and named it after himself. They are membrane bound organelles which are shaped like a sack. The Golgi is made up of stacks of membrane-bound structures. At each end of the stack there is a face which helps with the function of the Golgi. One end of the stack is called cis face and the other end is called tans…

defines endosymbiosis as a theory in which modern organelles such as mitochondria and chloroplasts are descended from bacteria which, at one time in their evolutionary…

membrane works as a barrier for the cell. Since it is semi-permeable, it allows some substances/particles into the cell but denies access to others. The cytoplasm is the fluid within each individual cell that surrounds the organelles. This is the 'place' where the organelles complete their individual tasks. The Rough Endoplasmic(RER) Reticulm is a part of a series of connected 'hallways' that carry materials to various parts of the cytoplasm. The RER has many ribosomes attached to it and it…

the cell and the nucleus also contains genetic material (DNA). The nucleus also contains hereditary information. Most chemical processes and reactions, which are controlled by enzymes, occur in the Cytoplasm. It also supports and protects the organelles. The Cytoplasm is a cytosol, a jellylike material and it is also clear and thick. It also holds the cytoskeleton fibres. A cell membrane controls what substances…

In the cell, you have a vast majority of organelles that perform as needed today to support it. These organelles must go by a certain way of processing each of its duties to keep it alive and healthy. It’s like an auto body factory. When one thing goes wrong it causes problems throughout the entire cell. This could cause major discrepancies and dysfunctions that would most likely cause the human body to shut down due to illness, sickness, disease or more severely, death. So it’s a must these…

Stratum Corneum: This is the outermost layer of the epidermis, consisting of dead cells (corneocytes). This layer is composed of 15-20 layers of flattened cells with no nuclei and cell organelles. Their cytoplasm shows birefringent filamentous scleroprotein keratin. The purpose of the stratum corneum is to form a barrier to protect underlying tissue from infection, dehydration, chemicals and mechanical stress. Desquamation, the process of…

Every cell in the body has a nucleus. The nucleus is the largest organelle and is contained within a membrane. The nucleus contains the body’s genetic material, which directs the activities, like the brain of the cell. This is built from DNA and proteins called histones coiled together forming a fine network of threads called chromatin. When under the microscope the most prominent part of the cell is the nucleus. The most visible structure within the nucleus is the nucleolus, which is where…

“I'm super nervous to meet the coach today” she says. She drives to practice. She meets the coach Bob. She thinks in the head the coach is kinda like the chromosomes because they teach you information about softball and how to hit a softball and catch a ball. The chromosomes In the cell Helps direct cell activity and stores necessary information for building proteins. “We are going to run a baseline drill” the coach says. (The girl) says to her friends “ isn't the baseline a little bit like the…
