Here's a breakdown:

* Genetically modified organisms (GMOs): This is the most common term used to refer to any organism whose genetic material has been altered using biotechnology techniques. This alteration can involve adding, deleting, or modifying specific genes.

* Transgenic organisms: This term specifically refers to organisms that have received genetic material from a different species. For example, a plant containing a gene from a bacterium.

Examples of GMOs:

* Crops: Many crops are genetically modified to enhance traits like pest resistance, herbicide tolerance, or nutritional value.

* Animals: Some animals are genetically modified for research purposes, production of pharmaceuticals, or improved agricultural traits.

* Microorganisms: Microorganisms are commonly genetically modified for various applications, including production of pharmaceuticals, biofuels, and industrial enzymes.

Important Note: The term "GMO" is often used broadly and can be controversial. Some people use it to refer to any organism with altered genes, regardless of the method used or the origin of the genes. However, the term "transgenic organism" is more specific and refers to organisms that have received genes from a different species.
