Nucleus – known as the brain of the
cell
Cell membrane – gives protection to
the cell and helps holding together the organelles
Cytoplasm – jelly-like substance that
holds together the organelles.
Endoplasmic Reticulum – consists of
smooth endoplasmic reticulum which lacks ribosomes, and rough endoplasmic reticulum
which has ribosomes.
Ribosomes – consists of RNA and
protein enzyme and helps in protein synthesis
Mitochondria – known as the powerhouse
of the cell and helps transport energy all throughout the cell
Golgi Apparatus – gather proteins and
lipids in the cell and distribute it.
Centrioles – releases spindle like
formations that is attached to the cell in one of the cell division stages
Lysosomes – helps breakdown larger
molecules to smaller molecules
<span>Vacuole – food and water is stored
here. It also store waste material
before it is transported outside of the cell.</span>

Explanation:
When scientists speak of evolution as a theory they do not mean that it is a mere speculation. It is a theory in the same sense as the propositions that the earth is round rather than flat or that our bodies are made of atoms are theories. Most people would consider such fundamental theories to be sufficiently tested by empirical evidence to conclude that they are indeed facts. As a result of the massive amount of evidence for biological evolution accumulated over the last two centuries, we can safely conclude that evolution has occurred and continues to occur. All life forms, including humans, evolved from earlier species, and all still living species of organisms continue to evolve today. They are not unchanging end-products.
Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
