Task 4
Written report. Mask this to the point and concise.
a)Explain how the features/ structures of each organelle in a eukaryotic cell enable it
to perform its function.
The organelles in prokaryotes cells, are different than the ones in human cells, because the
ones in pokaryotes cells, are mainly made so they can stay alive. So each organelle, has
their own specific function to help the cell survive. The nucleus of eukaryotic cells, works as
a brain for the cell, it keeps the dna and also the cell’s activities. 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. They contain enzymes that digest the cell’s used
parts. All of the cell’s organelles must work together to keep the cell healthy.
The cell membrane is the protective barrier that surrounds the cell and prevents unwanted
material from getting into it. The cell membrane has many functions, but one main function
that it has is to transport materials salts, electrolytes, glucose and other necessary
molecules into the cell to support necessary life functions. Not only does the membrane let
molecules into the cell, but it also lets wastes such as carbon dioxide out of the cell. The cell
membrane is made up of a phosholipid bilayer. Each phopholipid contains a hydrophilic, or
water loving head and ahydrophobic, or water fearing tail. These properties that the
phospholipids have and the specific orientation they are arranged in provide the cell with an
selectively permeable barrier.
This way mitochondria are responsible for ATP production; the endoplasmic reticulum
modifies proteins and synthesizes lipids; and the golgi apparatus is where the sorting of
lipids and proteins takes place, also Peroxisomes carry out oxidation reactions that break
down fatty acids and amino acids and detoxify poisons; vesicles and vacuoles function in
storage and transport.
