You already know that all living organisms are made up of cells, which are the tiniest units. But do you know that cells are made up of even smaller objects? Each of these objects is called a cell organelle. Do you want to know what these are and what their functions are? Let’s learn about them below.

Cell Organelle
A small organ-like structure present inside the cell is called a cell organelle. It has a particular structural makeup and performs a specific function. Depending upon the presence or absence of membrane, cell organelles can be classified into three categories, namely:
- Without membrane: Some cell organelles like ribosomes are not bounded by any membrane. They are present in prokaryotic as well as eukaryotic organisms.
- Single membrane-bound: Some organelles are bounded by a single membrane. For example, vacuole, lysosome, Golgi Apparatus, Endoplasmic Reticulum etc. They are present only in a eukaryotic cell.
- Double membrane-bound: Cell organelles like mitochondria and chloroplast are double membrane-bound organelles. They are present only in a eukaryotic cell.

Solved Exercise
Question 1: Write the name of different plant parts in which chromoplast, chloroplast and leucoplast are present.
Answer:
- Chloroplast are present in green parts of the plant like leaves, the stem of cactus, raw mango fruit etc
- Chromoplast are present in colourful parts of the plant like flowers, fruits etc
- Leucoplast is present in parts not exposed to sunlight like roots, potato etc.
Question 2: Name the organelles which show the analogy written as under
Answer:
- Transporting channels of the cell—— Endoplasmic Reticulum
- Powerhouse of the cell—— Mitochondria
- Packaging and dispatching unit of the cell—— Golgi Body
- Digestive bag of the cell—— Lysosomes
- Storage sacs of the cell—— Vacuole
- Kitchen of the cell—— Chloroplast
- Control room of the cell—— Nucleus
Nice work and Helpful >any thanks for your contribution.
Very much helpful people are intimated with this
Function of
Function of golgi body is produces the energy to cell
no it works as packaging unit of cell where proteins or lipids synthesized are modified and packed in form of vesicles and are transported within cell or outside
Hi everyone
This is too much knowledgeable PDF
