Cells have several essential structures that allow them to carry out life functions. The cell membrane forms a barrier around the cell that controls what enters and exits. Inside the cell are several organelles, each with their own functions. The nucleus is a key organelle that controls the cell's activities and holds the chromosomes containing DNA. Other important organelles include mitochondria for energy production, the endoplasmic reticulum for transporting materials, and ribosomes for protein synthesis. Together, these structures allow cells to carry out the basic processes required for life.

1. Cells Stucture and
Function

9. A cell is the smallest working
unit of all living organisms on our
planet earth, which is capable of
performing life functioning.

10. Cell
The term cell was first observed and
identified by an English physicist Robert
Hook in the year 1665.There were many
theories developed for cell. Later in the year
1839 a two German scientist – Schwann
and Schleiden provided few basic principles
of cell.

11. Structure
And Functions

12. The cell wall it helps in protecting the
plasma membrane and plays a vital role in
supporting and protecting the cells. It is a thick
outer layer made of cellulose.

13. The Cell membrane It is a double layered,
thin barrier, surrounding the cell to control the
entry and exit of certain substances.

14. The Cytoplasm it is a membrane, which
protects the cell by keeping the cell organelles
separate from each other. This helps to keep a
cell in stable. Cytoplasm is the site, where many
vital biochemical reactions take place.

16. Nucleus
Ribosomes
Mitochondria
Golgi Apparatus
LysosomesVacuoles
Endoplasmic Reticulum

18. The Nucleus they are the membrane bound
organelles, which are found in all eukaryotic
cells. It is the very important organelle of a cell
as it controls the complete activity of a cell and
also plays a vital role in reproduction.

19. The Nuclear membrane is the bilayer
membrane, which protects the nucleus by
surrounding around it and acts as a barrier
between the cell nucleus and other organs of a
cell.

20. The Nucleolus it is an important
membrane found inside the nucleus. It plays a
vital role in the production of cell's ribosome.

21. The Chromosomes it is made up of DNA
and stored in the nucleus, which contains the
instructions for traits and characteristics.

22. The Endoplasmic reticulum it helps in the
movement of materials around the cell. It
contains an enzyme that helps in building
molecules and in manufacturing of proteins.
The main function of this organelle is storage
and secretion.

23. The Ribosome it plays a vital role in
protein synthesis.

24. The Mitochondria they are double
membrane, filamentous organelles, which play
a vital role in generating and transforming the
energy. Mitochondria play a vital role in various
functions of the cell metabolisms including
oxidative phosphorylation.

25. The Golgi Bodies it helps in the movement
of materials within the cell.

26. The Lysosomes it is also called as suicidal
bags as it helps in cell renewal and break
down old cell parts.

27. The Vacuoles it helps plants in
maintaining its shape and it also stores water,
food, wastes, etc.

28. Deoxyribonucliec Acid (DNA) –
”command center of the cells”.
