Answer:
cell is the smallest unit of life
Answer:
Cells are the basic unit of life. In the modern world, they are the smallest known world that performs all of life’s functions. All living organisms are either single cells, or are multicellular organisms composed of many cells working together.
Cells are the smallest known unit that can accomplish all of these functions. Defining characteristics that allow a cell to perform these functions include:
A cell membrane that keeps the chemical reactions of life together.
At least one chromosome, composed of genetic material that contain the cell’s “blueprints” and “software.”
Cytoplasm – the fluid inside the cell, in which the chemical processes of life occur.
Below we will discuss the functions that cells must fulfill in order to facilitate life, and how they fulfill these functions.
Function of Cells
Scientists define seven functions that must be fulfilled by a living organism. These are:
A living thing must respond to changes in its environment.
A living thing must grow and develop across its lifespan.
A living thing must be able to reproduce, or make copies of itself.
A living thing must have metabolism.
A living thing must maintain homeostasis, or keep its internal environment the same regardless of outside changes.
A living thing must be made of cells.
A living thing must pass on traits to its offspring.
