    Organelles Essay

    • 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…

    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…

    Eukaryotes Research Paper

    • 491 Words
    • 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

    • 1794 Words
    • 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…

    The nucleus has many different parts within its structure, in which enables it to operate. Within its structure it contains chromosomes, DNA, proteins, chromatin, nuclear membrane, . The nuclear membrane is a thin layer that surrounds the nucleus and it has pores to allow materials to enter in and out of the organelle. This part of the nucleus helps it to function because it allows the nucleus to allow important materials such as proteins, in and out of the organelle. The chromosomes are made up…

    Includ Plant Cells

    • 520 Words
    • 3 Pages

    Plant cells are eukaryotic cells, or cells with a membrane-bound nucleus. Unlike prokaryotic cells, the DNA in a plant cell is housed within the nucleus. In addition to having a nucleus, plant cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. Organelles have a wide range of responsibilities that include everything from producing hormones and enzymes to providing energy for a plant cell.…

    Mitochondrion is an organelle that exists within the cytoplasm of eukaryote cells, they are considered to be one of the most important organelles. Mitochondrion is usually oval in shape and can vary in size from 0.5 - 1µm. Mitochondrion is composed of a double membrane, the outer membrane is smooth and encompasses the organelle whereas the inner membrane is folded to form layered structures called cristae. In between the outer and inner membrane, is an area called the…
