organ; organelles
An _______________ is composed of two or more tissues types, whereas ____________ are microscopic structures in a cell.
Organ and organelles are two important terms that are related to the biology of living organisms.
– Organ: An organ is a distinct part of an organism that performs a specific function. Organs are made up of tissues, which are composed of cells. Examples of organs include the heart, lungs, liver, and brain in animals, and the leaves, stem, and roots in plants.
– Organelles: On the other hand, organelles are small structures that are present within a cell, and they perform specific functions in the cell. Organelles are often referred to as the “organs” of the cell. Examples of organelles include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and chloroplasts.
In summary, an organ is a distinct structure that is made up of different tissues and performs a specific function in an organism, while organelles are small structures that are present within a cell and perform specific functions to maintain the cell’s life.
