labelled diagram of parts of a flower

Use of the diagram to understand the complex matters in the science subjects is a age old process, even Michael Angelo, the famous painter of his time tried to draw the diagrams showing the human anatomy to understand the structures in a better way.
When we try to study the biology or rather precisely our relations to the plant kingdom and its peculiarities then it is obvious that we would be required to know about the plant cells, the smallest unit of the plant.

To understand it in a better way it is a traditional activity in a high school biology class is to have students draw plant cell diagrams. A well drawn and labeled plant cell diagram always helps to understand the function of the plant cell as a whole and the functioning of its organelles too. It is advisable that when drawing a plant cell diagram try to draw each organelle proportionately as this provides a better look to the diagram. A similar problem exists with plant cell diagrams displayed in the textbooks.

Many times students are misled into thinking that the organelles are very large in size.
Usually the plant cells are eukaryotic in nature and they are microscopic in size, in other words they can only be seen clearly with the help of a high powered microscope. The plant cells are somewhat rectangular in shape and there are few distinct features like cell wall, chloroplast and vacuole are present in these cells which separates them from the common animal cells. While drawing a diagram of a plant cell first thing to remember is that clearly define the cell wall, after that the most prominent structures to be defined or depicted are nucleus, vacuole, chloroplasts, Golgi complexes etc. Sometimes the presence of the cell sap is also shown using colored dots or using some light color.

After the cell wall the plasma membrane should be drawn followed by the nucleus and if a larger detail is required then nucleolus, nuclear pores and chromatins should be shown. After that mitochondrion should be shown as these are vital part of any plant cell, the number of mitochondria may vary from cell to cell. Then it is the turn to show the chloroplasts, usually these structures are shown in green color. Then the endoplasmic reticulum is shown with ribosomes attached to it.

After you have done with the endoplasmic reticulum it is the turn for the Golgi complex then go on and add Lysosomes if you desire as Lysosomes are present in only some of the plants. Then you may show the peroxisomes, microtubules and microfilaments to give your drawing of the plant cell completeness. Do not forget one more vital part of the plant cell, Vacuole, the shape of the vacuole is irregular and size varies from time to time hence you can use this part to fill the extra space left in the plant cell diagram. After you have finished the drawing, color the different parts of the plant cell in different colors and then label it.
