What are cells made up of Class 9?
Answer: The cytoskeleton, cell membrane and cell organelles make up a cell. The specific cell organelles and their functions are referred to as the cell’s structural organisation.
What is cell class 9 short answer?
“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently.
What is cell biology made of?
Cell biology encompasses both prokaryotic and eukaryotic cells and has many subtopics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several microscopy techniques, cell culture, and cell fractionation.
What are cells made of simple definition?
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks.

The cell was first discovered and named by ROBERT HOOKE in 1665.
Why are cells made?
Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.
What are cells made of cells?
Cells are composed of water, inorganic ions, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
Who was the father of cell?
The Legacy of a Founding Father of Modern Cell Biology: George Emil Palade (1912-2008)
What is a cell made up of in physics?
Inside cells, atoms make up molecules. Those molecules make up organelles inside cells, compartments that have specific functions, and organelles together make up cells.
What is a cell class 9 computer?
Ans: A cell on a spreadsheet is the intersection of a row and a column. In applications with spreadsheets, a cell is a box where you can enter a single piece of data.
Are cells made up of atoms?
Yes, cells consists of atoms. Atoms are the building blocks of all things on Earth, both living and non-living. All the components of a cell, such as the cell membrane, cytoplasm, DNA, are made up of atoms. For example, the cell membrane is made up of fat, and fat is made up of carbon, hydrogen, and oxygen atoms.
What are cell organelles made up of?
Macromolecules such as carbohydrates, lipids, proteins, and nucleic acids (DNA, RNA) make up all cellular organelles.
