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 are organelles definition for kids?
In cell biology, an
organelle is a part of a cell that does a specific job
. … Organelles typically have their own plasma membrane round them. Most of the cell’s organelles are in the cytoplasm. The name organelle comes from the idea that these structures are to cells what an organ is to the body.
What is the science definition of organelle?
Organelle,
any of the specialized structures within a cell that perform a specific function
(e.g., mitochondria, ribosomes, endoplasmic reticulum). Organelles in unicellular organisms are the equivalent of organs in multicellular organisms.
What is organelles and example?
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 are organelles simple definition?
An organelle is

What are the functions of the 13 organelles?
- nucleus. contains the cell’s DNA and is the control center of the cell.
- endoplasmic reticulum. transports materials within cell; process lipids.
- mitochondria. breaks down food to release energy for the cell.
- cell membrane. …
- ribosome.
- cytoplasm.
- golgi body.
- lysosome.
What are organelles found?
Organelles are
embedded within the cytoplasm of eukaryotic and prokaryotic cells
. In the more complex eukaryotic cells, organelles are often enclosed by their own membrane. Analogous to the body’s internal organs, organelles are specialized and perform valuable functions necessary for normal cellular operation.
Why do cells have organelles kids?
Special structures, called organelles, within the cytoplasm
perform specific functions
. For example, some organelles make important substances called proteins. Cells use proteins in most of their chemical processes. Other organelles change food molecules into material needed for energy and growth.
What’s another word for organelle?
- cell nucleus.
- cilium.
- nucleole.
- centriole.
- nucleus.
- organ.
- mitochondrion.
- karyon.
What are four facts about organelles?
Organelles typically
have their own plasma membrane round them
. Most of the cell’s organelles are in the cytoplasm. The name organelle comes from the idea that these structures are to cells what an organ is to the body. There are many types of organelles in eukaryotic cells.
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 is the most important organelle?
The nucleus
is the most important organelle in the cell. It contains the genetic material, the DNA, which is responsible for controlling and directing all the activities of the cell. All the RNAs needed for the cell are synthesised in the nucleus.
What does the word organelle mean literally?
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.
How many types of organelles are there?
Cell organelles can be divided into
three types
General cell organelles: they are present in both animal and plant cells all the time – cell membrane, cytosol, cytoplasm, nucleus, mitochondrion, rough and smooth endoplasmic reticulum, Golgi apparatus, peroxisome, lysosome, and the cytoskeleton.
What are the example of cell organelles?
➡️Cell Organelles are the membrane-bound compartment or structure in a cell that performs a special function. Example :- the
nucleus, endoplasmic reticulum, golgi apparatus, mitochondria
,etc.
