carried out in there. Complex sugars including glycogen and melanin which is the pigment responsible for skin and hair colour are in the cytoplasm. These chemicals are the basic living materials that a cell needs. Organelles are the various components of a cell with a specific structure and function and are linked to miniature organs. These include: Mitochondria: These are small components within cells that perform different important functions in order to keep the body healthy. They make the energy

Endocytosis is when a substance gains entry into a cell without passing through its cell membrane. A cell's plasma membrane encloses and fuses to lock foreign material inside. An intracellular vesicle is formed as result .The ribosomes of the inner structure in chloroplasts and mitochondria resemble prokaryotic ribosomes. Evolutionist Lynn Margulis proposed the idea in the late 1960’s. In 1970 she published her argument in The Origin of Eukaryotic Cells. The controversy surrounding theory is that it

This assignment will discuss about the Prokaryotic and Eukaryotic cells by comparing their structure and function: It will talk about the similar components they have and their function of the two cells (prokaryotic and Eukaryotic) and then it will talk about the different components and their function in the cell. It will relate the structure to function in two specialised eukaryotic cells and the structure of the cell membrane to its function of movement of substances into and out of the cell.

network of interconnected membranes forming channels within the cell. A site for synthesis and metabolism of lipids. Also contain enzymes for detoxifying chemicals including drugs and pesticides. RIBOSOMES All living cells contain Ribosomes, tiny organelles composed of approximately 60% RNA and 40% protein.In eukaryotes, ribosome are made of four strands of RNA. In prokaryotes, they consist of three strands of RNA. LYSOSOMES The main function of these microbodies is digestion. Lysosomes break

Thomas Spann Biology Lab Plant Cell Definitions and Functions Nucleus: The cell nucleus is supposed to be the most important organelle. It carries the genetic information present in this organelle which inherits the physical traits from one generation to another. It has a dark stained nucleolus mainly responsible for protein formation. Apart from this, the nucleus coordinates all the cell functions and regulates the metabolism of plants. The passage of food and water and the influx of nutrients

Cell Essay This is my essay for converting a cell into a city. I started out with creating a cell wall. I made a Nordic wall of stone to protect the city. Next I did the cell membrane which I transformed into a draw bridge to fit the theme. For the cytoplasm I put grass because it makes up the shapes of the cell/city. The next big project was the chloroplast which I turned into solar panels and smokestacks because it takes in sunlight and releases CO2. On the inside I put greens and vines. The

Organelles and Disease: Adrenoleukodystophy (ALD) Understanding an Animal Cell: Basic Units of Life The cell is the fundament unit of life. They make up the smallest level of a living organism in the human body, where the metabolic processes happen to in order to maintain life. It itself is considered a mini-organism made up from organs called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell

A plant cell is like a jungle because the organelles in a plant cell are very similar to the organisms in a jungle. Both of these things are very different, but when you think about what’s inside of a plant cell and a jungle, it’ll make sense. The nucleus of a cell is known for controlling the organelles and their functions. In shorter words, it’s the boss of the cell. A lion’s nickname is “the King Of The Jungle”, so this proves the point that they are related in a way. Lions are also known as

1.1 Compare the ultra structure of a prokaryotic and a eukaryotic cell. ANSWER: Prokaryotic and Eukaryotic organisms: are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane while membranes are composed of phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure. The main different between the both cell organism is nucleus: Prokaryotic cells are smaller and simpler organisms without no nucleus but most are unicellular, while eukaryotic
