EVERYDAY SCIENCE

Detailed explanation-1: -Yes, all living things are made up of cells. In 1665, Robert Hooke discovered the existence of cells using a microscope, which further paved the way for the discovery of various other microscopic organisms. Some organisms consist of a single cell, for example, the amoeba.

Detailed explanation-2: -Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.

Detailed explanation-3: -All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.

Detailed explanation-4: -By the early 1800s, scientists had observed the cells of many different organisms. These observations led two German scientists, named Theodor Schwann and Matthias Jakob Schleiden, to propose that cells are the basic building blocks of all living things.

Detailed explanation-5: -All living things, or organisms, are made up of at least one cell. Some organisms, such as amoebas, are made up of only one cell and are therefore called unicellular organisms. On the other hand, multicellular organisms, such as humans, are composed of more than one cell.
