Answer:
The correct answer is - Organelles would not receive the products they need to function and materials that were made within the cell would not be able to leave the cell for use.
Explanation:
In the absence of the Golgi apparatus, there would be many changes and negative impact would be on the cell such as lysosome would be lacking also and digestion would not be possible. Golgi apparatus functions as the modifying agent of protein and lipid that come from ER and transport them out of the cells to the desired organ.
The modification and transport of lipid and protein produced would be stopped and might float in the cytoplasm. If the particular organ does would not get the hormone, lipid molecule or particular enzyme, the organ will fail to do its function and homeostasis of organism would be affected.
Carbon dioxide (CO2) is formed from one carbon atom bonded to two oxygen atoms. Therefore, carbon dioxide is a compound!
