draw diagram of plant cell and explain its part ?
diagram must be in copy neat and tidy?

Plz refer to the attachment for the DIAGRAM.
Explanation of plant cell
1)Plant cells are made of basically two regions =The Cell wall and Protoplasm(Nucleas +Protoplast) .
2)It is made of organic molecules like protein.
3)Parts of a plant cell(Cell Organelles)=>
A) CELL WALL
-Every plant cell is covered by a carbohydrate rich rigid wall called cell wall of an plant cell
-The main components of cell wall is cellulose fibrils.
B) Protoplasm
-The substance that is present inside the cell which includes Protoplast and Nucleas is together called Protoplasm.
C) Nucleas
-It is the part of plant cell that is almost found in every plant cell except mature sieve tubes and mammalian erythrocytes. It is the largest cell organelle.
D) Cytoplasm
-It is the cell organelle that is found inside plasma membrane and outside the nucleus.
-It is the heterogeneous mass containing granules of different sizes and shapes.
E) Ribosome
-It occur free in the cytoplasm and is attached to the endoplasmic reticulum.
-They are also present in the chloroplastids.These are aggregates of ribosome and are also known as the polyribosome or polysome.
F) Mitochondria
-It is called as Powerhouse of the cell as it produces energy from the food by oxidation of gluscose.
-They are small rod shaped cells.
G) Lysosome
-They are known as Sucidal bags of cells as they contain enzymes which helps in digestiin and killing of microbes.
-They don't have any internal structure.
H) Plastid
-They are small and variously shaped organelles present in cytoplasm of plant cells.
-They can be coloured or non coloured.
-They are of two types =>
i) Leucoplast (Non coloured)
ii) Chromoplast (coloured)
I) Endoplasmic Reticulum
-It is cell permeated by complex elaborate system of membranes which are termed endoplasmic reticulum.
-It is of two types =>
i ) Rough ER
ii) Smooth ER
It can be called the brain of the plant cell and the most important of all plant cell parts. This is because the cell nucleus performs all the administrative tasks of the cell. It coordinates all the metabolic functions. Cell growth, cell division, and protein synthesis are some of the tasks that are coordinated by the nucleus.
Plastids
Plastids are those plant cells which carry pigments. So, it goes without saying that chloroplast happens to be the most important of all plastids, because they contain green chlorophyll pigments. Chloroplast plastids photosynthesize sunlight and make food for the plants.
Ribosome
These predominantly contain ribonucleic acids (RNA). Their composition contains almost 60% of the ribonucleic acids and 40% of proteins. Ribosomes are those parts that are responsible for the synthesis of proteins in plants.
Mitochondria
Complex carbohydrates and sugars are very difficult to breakdown. The mitochondria is responsible for this task. They break complex carbohydrates into very simple form, which is easily used in plants. They are called the powerhouse of the cell.
Golgi Body
Also known as golgi complex or golgi apparatus, it is used to transport material inside and outside the cell. Golgi body alters and prepares lipids for their transport outside the cell.
Endoplasmic Reticulum
Endoplasmic Reticulum (ER) is a network of convulsed sacs, which are in turn interconnected. The cytoplasm of the plant cell and nucleus are connected by the endoplasmic reticulum. There are two types of ER, which are distinguished according to the presence of ribosome. They can be called smooth or rough. Endoplasmic reticulum is that structure which basically transports glycogens, proteins, and other compounds.
Vacuoles
'Turgor pressure' is that pressure in a plant cell that helps in maintaining its shape. Vacuoles in all of plant cell parts do the job of maintaining this pressure. Basically, there are many vacuoles, but the centrally located one is larger than the others.
Peroxisomes
Fatty acids have to be broken down metabolically into simple sugar forms. Peroxisomes contain certain oxidative enzymes that are responsible for breaking such fatty acids into simpler forms. Peroxisomes also help chloroplasts in the process of photosynthesis.
In this article, I have tried to explain the parts of a plant cell and the functions very briefly. The coordination of all functionalities in plants are very important for carrying out every metabolic activity.
Hope it helps☺☺☺
