What is the smallest unit in physics?

The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.

Which is the smallest unit of area?

What is cell the unit of life?

A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Who is largest cell?

Biologists used the world’s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.

What is the smallest unit of work?

Work packages are the smallest unit of work that a project can be broken down to when creating your Work Breakdown Structure (WBS).

Is cell smallest unit of life?

The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

What is SI unit of work done?

jouleThe SI unit of work is the joule (J), named after the 19th-century English physicist James Prescott Joule, which is defined as the work required to exert a force of one newton through a displacement of one metre.

Which cell is largest cell?

The sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, which we term male and female.

Which is the biggest unit of energy?

JouleAnswer and Explanation: In the SI unit system, Joule (J) is considered as the largest unit of energy.

Which is the smallest unit of light energy?

photonbundle of light energy is called a photon. This is the smallest distinct and measurable unit of light energy.

Is cell the basic unit of life?

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell’s internal and external environments.

Which is largest animal cell?
