Their structure is a small network of protein fibers which are not surrounded by a membrane but are located in an area of the cell called the centrosome. The centriole has its appearance and structure the way it is because its arrangements must be a circular and the triplet fibers that it’s made out of will eventually create a shape that is similar to a barrel when it it is arranged.
One of their main function is to contribute/help with processes that involve cellular activities. One example of cell division where centriole plays a role in mitosis where the organelles creates spindle fibres. These fibers allow chromosomes to be separated from each during mitosis and the can create daughter cells. The centrioles play a key role …show more content…
More so, two membranes help with this, where one is called the outer and inner membranes - specifically these two membranes serve as the shield for the inner parts of the chloroplast. The third membrane is called the thylakoid. The outer and inner membrane holds a semi-gel-like fluid called stroma, the chloroplast holds this fluid and is mainly the fluid that takes up the volume of it. Whilst the thylakoids is found in the stroma.
One of their main function is to complete a biological process called photosynthesis. When photosynthesis is taking place, the plant cell will obtain using the sun to gets its energy and then ultimately converting it to sugars. This will only occur once that sun has become exposed to the chloroplast causing itself and the chlorophyll molecule which can be found on the surface of the organelle to go to the chemical energy it needs. The creation of ATP energy will not be possible if the potential energy of H+ ions is not used, so this is why chloroplasts will need to use the energy like mitochondria does to make ATP to
