What is a Cell Made Up of?
What is the Structural
Organisation of a Cell?
Answers
Explanation:
cell is the basic functional biological unit that makes up life and living organisms. It is composed of many molecules that come together in a unique way, allowing the cell to perform simple tasks. There are two cell types, prokaryotic and eukaryotic which differ in size, organization, components, etc. We are made from eukaryotic cells - so are plants, fungi, protists, and all other animals.
Think of a cell as a castle, the castle has many parts that work together to keep the community inside running smoothly. The eukaryotic cell of a human has a membrane that separates it from the outside world. This membrane allows certain molecules in and others out (this is like the moat and wall that surrounds the castle).
Inside the cell there are many different organelles (basically mini organs) that all have their own function.
Cytoskeleton helps maintain the structure, this is like the interior wall of the castle that supports the outside wall.
Mitochondria is the “powerhouse of the cell” and generates most of the energy needed. It is like a fireplace in the castle.
Endoplasmic reticulum manipulates products and exports them. Think of the castle making a product and then sending it out to neighboring castles.
Golgi apparatus helps further process and package material from the endoplasmic reticulum.
Nucleus stores all of the genetic information, allowing the cell to duplicate and pass on everything about it to the next generation. This is like a historian that passes on books that contain the history of the castle, as well as instructions on how to do everything, from building walls, to cleaning, to making new products, etc.
There are a few others, but this is a good start.
These cells then come together to eventually form larger structures called tissues and then organs. All cells in our body come from one parent cell (when egg and sperm meet). As the cells copy and divide they become specialized. Think of multiple castles working together, one castle can manage the army (immune system), another castle controls food production (gastrointestinal system), and another houses the King who commands over the entire area (brain and central nervous system). All of these cells have the same basic layout and parts, but they are specialized for their specific tasks.
Answer:
Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules such as proteins and nucleic acids. Most plant and animal cells are only visible under a microscope, with dimensions between 1 and 100 micrometres.
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
A cell is made up of cell membrane, cell organelles and the cytoskeleton. The structural organization of the cell refers to the particular cell organelles and their function. Cells have particular structures that perform specific jobs. These cell structures are called organelles and perform the actual work of the cell.
