Biology: Cell Structure I Nucleus Medical Media
Nucleus Medical Media
Understanding Cells: The Smallest Living Units
Cells are the smallest living units of an organism
...
The cytoplasm is a jelly-like fluid
that fills the cell and provides a medium for the cell's organelles to function
...
The genetic material of a cell is contained within its nucleus
...
Eukaryotic cells are more advanced and complex, with organelles
such as the nucleus and specialized structures
...
Prokaryotic cells, such as bacteria, are unicellular organisms that do not have a nucleus
...
However, eukaryotic cells, which are found in plants, animals, and fungi, have a nucleus that
serves as the control center of the cell
...
Organelles, such as mitochondria, ribosomes, and the
endoplasmic reticulum, perform specific tasks in the cell
...
The endoplasmic reticulum is involved in the synthesis,
processing, and transport of proteins and lipids
...
However, when the cell is
ready to divide, the DNA condenses into chromosomes
...
Once the ribosomes are produced, they leave the
nucleus
...
They are
located outside the nucleus and are found floating within the cytoplasm, a gel-like substance
that houses other organelles
...
Functions of Ribosomes
●
Synthesis of proteins
Ribosomes are responsible for taking genetic instructions from DNA and using them to create
proteins
...
Ribosomes in the Cytoplasm
The cytoplasm is a jelly-like substance that fills the cell and is home to various organelles,
including the ribosomes
...
The Endoplasmic Reticulum (ER) is a membrane-enclosed passageway used for transporting
materials, including proteins synthesized by ribosomes
...
Proteins and other materials emerge from the ER in small vesicles, which are then transported
to the Golgi apparatus
...
As proteins travel through the Golgi body, they undergo modifications and are
transformed into shapes that can be utilized by the cell
...
Functions of the Golgi Body
●
●
●
Processing and modifying proteins
Sorting and packaging proteins for transport within the cell or outside of the cell
Producing lysosomes, which are responsible for breaking down waste within the cell
Overall, the Golgi body is an essential component of cellular function and plays a vital role in the
processing and modification of proteins
...
Plant and animal cells have different structures that serve different functions
...
Vacuoles are sac-like structures that store different
materials
...
