Answer:
Here's your answer.
Explanation:
The fundamental organisational unit of life is the cell.
Different cell organelles in a Cell are -
(i) Endoplasmic reticulum (ER) : The endoplasmic reticulum is a large network of membrane bound tubes and sheets. The ER membrane is similar in structure to the plasma membrane. One function of the year is to serve as channels for the transport of materials between various regions of the cytoplasm or between the cytoplasm and nucleus. ER also functions as a cytoplasmic framework providing a surface for some of the biochemical activities of the cell.
(ii) Golgi apparatus : The Golgi apparatus consists of a system of membrane bound vesicles arrange approximately parallel to each other in stacks called cisterns. Its functions include the storage modification and Packaging of products in vesicles the Golgi apparatus is also involved in the formation of lysosome.
(iii) Lysosomes: Structurally, lysosomes are membrane- bound sacs filled with digestive enzymes. These enzymes are made by RER. Lysosomes are a kind of waste disposal system of the cell. Lysosomes are also known as suicide bags of a cell.
(iv) Mitochondria : Mitochondria are known as the powerhouse of the cell mitochondria have two membrane coverings. Mitochondria are strange organelles in the sense that they have their own DNA and ribosomes. Therefore, mitochondria are able to make some of their own proteins.
(v) Plastids : Plastids are only present in plant cells.
(vi) Vacuoles : Vacuoles are storage sacs for solid or liquid contents. Vacuoles are small sized in animal cells while plant cells have large vacuole .
