Relationship Between Cell Structure & Function. By Contributor; Updated All living things require a source of energy. Factories are linked up. Cell Structure and Function. All living things are composed of cells. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. work together in animals and plants, including relationships between organelles, cells, tissues. The distinctive structure of a jet uses principles of physics to enable it to take off and remain airborne. Its form is directly connected to its function. Living things.
Nucleus In the same way that the main building controls a gigantic factory, the nucleus is the control center of the cell. This organelle holds the cell's DNA and the directions for producing proteins and other vital things.

The nucleus is bordered by a nuclear envelope that is made up of two membranes. This envelope is dotted with thousands of nuclear pores, which permit material to go through the nucleus.
Like messages, instructions and blueprints moving in and out of a main office, a river of proteins go through the nuclear pores to and from the rest of the cell. Ribosomes Creating proteins is one of the most crucial jobs in a cell.
The Organization of Living Things: Structure/Function Relationships
They are made on ribosomes. Ribosomes are puny pieces of protein found all over the cell. Each ribosome, in its own way, is like a small machine in a factory, spiraling out proteins on instructions that arrive from its nucleus. The endoplasmic reticulum is the site where the apparatus of the membrane are assembled, along with proteins and other materials that are exported from the cell.
The rough ER is given this name because of the ribosomes found on its surface. Newly made proteins leave these ribosomes and are put in the rough endoplasmic reticulum, where they will be modified chemically. Golgi Apparatus Proteins made in the rough ER move next into an organelle called the Golgi apparatus. This organelle was discovered by the Italian scientist Camillo Golgi.
In the Golgi apparatus, proteins are put all over the cell Lysosomes Even the neatest, cleanest factory needs a cleanup crew, and that's what lysosomes LY-suh-sohmz are. Lysosomes are small organelles filled with enzymes.
One function of lysosomes is the digestion of lipids into molecules that can be used by the rest of the cell. Plant cells have chloroplasts, a cell wall and a central vacuole. Animal cells lack these three organelles. Plant cells have chloroplasts because they make their own food.

Plant cells have a cell wall so that they do not burst when the central vacuole fills up with water. Prokaryotes do not have a nucleus, and lack membrane bound organelles.Structure and Function in Biology
They are the oldest cells on earth. Prokaryotes often move using special structures such as flagella or cilia. Cells have many structures inside of them called organelles. These organelles are like the organs in a human and they help the cell stay alive. Eukaryotes also have a golgi apparatus that packages and distributes proteins. Mitochondria are the power house of the cell and provide the cell with energy.
Both plant and animal cells have mitochondria.
Lysosomes are like the stomach of the cell.
