Why are cells described as the "building blocks" of all living things?
Question 14 options:
Cells are always stacked in rows, like bricks, to build the parts of living things.
They are found in everything living things need, including water and food.
A cell is the smallest part of a living thing that can function on its own.
A cell is the smallest part of the air living things need to breathe.
A cell is the smallest part of a living thing that can function on its own.
The correct option is:
A cell is the smallest part of a living thing that can function on its own.
Cells are described as the "building blocks" of all living things because they are the basic structural and functional units of life. They are capable of carrying out all the necessary processes for life, such as obtaining energy, reproducing, and responding to their environment. Just like a brick is the smallest unit used to build a structure, a cell is the smallest unit that can perform the essential functions of an organism.
The correct answer is: A cell is the smallest part of a living thing that can function on its own.
Cells are often described as the "building blocks" of all living things because they are the basic structural and functional units of life. Just like building blocks are used to construct buildings, cells are used to construct living organisms. Every living organism, from the tiniest bacteria to the largest animal, is made up of cells.
To understand why cells are considered the building blocks of living things, it's helpful to know what a cell is. A cell is the smallest unit of life that can replicate independently and carry out all the necessary functions of life, such as metabolism, growth, and reproduction. Cells contain various organelles and structures, each with a specific role in maintaining the overall function of the cell.
Cells can exist as single-celled organisms, such as bacteria, or they can come together to form multicellular organisms, such as plants, animals, and humans. In multicellular organisms, different types of cells specialize in performing specific functions to contribute to the overall functioning of the organism. For example, in humans, there are muscle cells, nerve cells, blood cells, and many others, each with their own unique structure and function.
In summary, cells are described as the "building blocks" of all living things because they are the smallest units of life that can function independently, and they come together to form the complex structures and systems that make up living organisms.
