Answer:
Nucleus
All plant and animal cells, which are eukaryote organisms, contain a true nucleus bounded by a nuclear membrane. (Prokaryotes such as bacteria and archaea don't have a nucleus.) This structure contains a eukaryotic cell's DNA and directs cell activities.
Endoplasmic reticulum
The cell membrane is double-layered in animals, and forms the outer cell boundary that protects the cell contents and regulates what goes in and out of cells. In plants, a plasma membrane lies just underneath the tough cell wall that supports plant tissue.
Golgi Apparatus
Also called the Golgi complex or Golgi body, this organelle looks like a stack of flattened water balloons. It processes the proteins produced by the endoplasmic reticulum and ribosomes, modifying and storing them until it packages them in vesicles. Lysosomes also come from the Golgi apparatus. These are sacs containing enzymes capable of breaking down cell macromolecules
Storage Organelles
Vesicles are membranous sacs that transport or store a variety of compounds. Produced primarily in the membrane systems of the plasma membrane, endoplasmic reticulum and Golgi apparatus, they move throughout the cell along cytoplasmic filaments to discharge their contents to other organelles or outside the cell.
Energy-Producing Organelles
Mitochondria are peanut-shaped organelles found in both plants and animals. The sites of cellular respiration, they break down sugar to fuel the cell. Chloroplasts occur in plant cells. They contain chlorophylls, and photosynthesis occurs within them, allowing plant cells to form sugar from air and water in the presence of sunlight.
Membrane
A cellular membrane, also called a plasma membrane, surrounds all cells. This membrane functions to give the cell shape, and to keep the internal components confined and separate from the extracellular fluid that surrounds all cells. Plasma membranes consist of lipids, fatty or wax-like substances, and proteins. The most common lipid found in membranes, known as phospholipids, contains a phosphate group connected with a glycerol group and two fatty acid chains.

Cytoplasm
The remaining part of the cell bound by the plasma membrane and surrounding the nucleus is the cytoplasm. The cytoplasm consists ofof a jelly-like matrix that holds the other organelles of the cell, including the mitochondria and endoplasmic reticulum. Proteins, amino acids and sugars used for growth and cellular reproduction are contained within the cytoplasm. The cytoplasm serves several important cellular functions.
