:
a specialized cellular part
(such as a mitochondrion, chloroplast, or nucleus) that has a specific function and is considered analogous to an organ.
What is cell organelle in short?
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the
suffix -elle
being a diminutive.
What is a simple definition of organelle?
An organelle is
a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body
. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
What is organelle in a sentence?
Organelles sentence example
Plant and animal cells contain organelles ,
structures that perform special functions within the cell
. All the cellular organelles may be seen in detail.
What is an organelle give an example and definition?
The definition of an organelle is
a structure in a cell with a specific function
. An example of an organelle is a centriole. … The nucleus, the mitochondrion, the chloroplast, the Golgi apparatus, the lysosome, and the endoplasmic reticulum are all examples of organelles.
What is the best definition of an organelle?
: a specialized cellular part (such as a mitochondrion, chloroplast, or nucleus)
that has a specific function and is considered analogous to an organ
.
What does the term organelle literally mean?
Organelles are specialized structures that perform various jobs inside cells. The term literally means “
little organs
.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
Which organelle is called suicidal bags of cell?
50 years ago, Christian de Duve introduced the term “suicide bags” to describe
lysosomes
(1), the organelles containing numerous hydrolases, which were, until the discovery of the ubiquitin-proteasome system, thought to be responsible for the major part of the intracellular turnover of proteins and other macromolecules …
What organelle can you live without?
You can’t survive without
mitochondria
, the organelles that power most human cells.
What is a cell organelle Class 9?

What is structure of cell?
A cell consists of three parts:
the cell membrane, the nucleus, and, between the two, the cytoplasm
. … Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
How many cell organelles are there?
- Nucleus. nucleus; animal cell. …
- Ribosomes. Ribosomes are the protein factories of the cell. …
- Endoplasmic reticulum. Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells. …

What are the two main types of cells?
A living thing can be composed of either one cell or many cells. There are two broad categories of cells:
prokaryotic and eukaryotic cells
. Cells can be highly specialized with specific functions and characteristics.
What is the advantage of having organelles?
Membrane-bound organelles offer several advantages to eukaryotic cells. First, cells can concentrate and isolate enzymes and reactants in a smaller volume, thereby
increasing the rate and efficiency of chemical reactions
.
How does an organelle function?
Organelles are structures within a cell that perform specific functions
like controlling cell growth and producing energy
. Plant and animal cells can contain similar types of organelles. … These cells can contain some non-membranous organelles like flagella, ribosomes and circular DNA structures called plasmids.
