    • 1254 Words
    • 6 Pages

    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 organelles. The largest and most important membranous organelle is the nucleus. The nucleus contains a dense structure called the nucleolus and surrounded by a double membrane called the nuclear envelope. The nuclear envelope has little holes in it called…

    Organelles in the Cell Cells are the smallest structural unit of all organs and organ systems. They are essential to life. Both animal species and plant species need cells to maintain life. Cells have many and are made up of many organelles that have specific jobs. Animal and plants cells are different, but mainly composed of the same things. Each organelle is significant to its cell, which are the building blocks of life. At the center of almost every cell is a dense organelle called the…

    Organelles of Animal Cells The Nucleus: ~A large, round organelle visible under the microscope. Functions- Regulation • Controls the cell’s activities • Controls cell reproduction Contains genetic material - DNA that makes up the genes and chromosome. The Ribosome: ~Made of dozens of different proteins as well as RNA, also found in large numbers in the cytoplasm of living cells. Ribosome are typically composed of two subunits: • Large subunit • Small subunit “ Free” Ribosome makes…

    Organelles work together to maintain a cell's internal process and functions by providing the necessary needs for the cell. Although this mainly applies to Eukaryotic cells, this can also apply to Prokaryotic cells. Prokaryotic cells perform some of these function, but in a simpler way. Organelles work together to protect the cell, provide energy, repair the cell, direct the cell, and clean up the cell. First, organelles work together to protect the cell. The cell membrane is the main organelle…

    Our human body consists of several different types of organs for example, lung, heart and kidney each organs have specific function that they carry out. Small part of the cell which is called organelles, they have been adapted to carry out certain function and this can be more than one. Organelles are found in eukaryotes and they are always surrounded by protective membrane. Mitochondria which is the organelle it acts like a digestive system because it takes in all the nutrients, breaks them…

    The cell has many parts. Those parts include the cell membrane, cytoplasm, nuclear membrane, nucleus, ribosomes, mitochondria, small vacuoles, lysosomes, endoplasmic reticulum, and the golgi apparatus. We compared all of these organelles to a plastic bag, a toy animal, a large toy bear head, a highlighter, a noise maker, a medicine cup, a candle, a straw, and a box. To begin, a cell membrane controls movement in and out of the cell. It is a thin flexible layer that also supports and…

    The nucleus, controlling all of the cell's activities and containing its genetic information, remains the most important organelle of the cell today. Although the first observations of the nucleus can be dated back to the 1700s, Robert Brown is often the man given credit for its discovery. In 1831, he noticed an opaque mark in a plant cell. Brown was not aware at the time, but he had sparked thought for many scientists. Soon it was discovered that the nucleus could be found in more than just…

    • 2 Pages

    The simple definition of Eukaryotes is that they are any organism whose cells contain a nucleus and other membrane enclosed organelles. Taxonomically, Eukaryotes belong to the taxon Eukarya. The three types of eukaryotic microbes are fungi, protozoa, and algae. Because the three types of eukaryotic microbes are all composed of eukaryotic cells, they have basic similarities in cellular structure, including the presence of a nucleus. However, these types of microbes do differ in many significant…

    Introduction to Cell Biology – Unit 10193 – Chloe Barrett This essay discusses the difference in prokaryotic and eukaryotic cells, two types of specialised eukaryotic cell, and the relation of the structure of cell membranes to their function of moving substances in and out of cells. Prokaryotic and Eukaryotic cells are two very different, but also very similar cells. There are many differences between them that can help to associate between each one. Eukaryotes are any organism that…

    Ribosomes Essay

    • 8 Pages

    The structure of the mitochondria is extremely important to the functioning of the organelle. It has two membranes, a smooth outer membrane, and a convoluted inner membrane which allows cristae to be formed. Between the two membranes is a narrow intermembrane space and within the inner membrane is a larger internal matrix. Both contain a complex mix of specialised proteins. The outer membrane acts like a filter by having channels that prevent large particles from passing through. The inner…
