What are the functions of nucleus, plastids,cell wall ,cell membrane,vacuoles

Solution
Nucleus
This organelle has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
PLastids
Plastids are the site of manufacture and storage of important chemical compounds used by the cell. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.
cell wall
The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.
cell membrane
It consists of a lipid bilayer with embedded proteins. Thebasic function of the cell membrane is to protect the cellfrom its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
vacuole
Function of the Vacuole. A vacuole is usually found in all plant and fungal cells, as well as some cells of protists, animals, and bacteria. These membrane-bound structures are basically just enclosed compartments thatare filled with both inorganic and organic molecules, along with water to support the organelle.
