Why is the cell important?
Cells are the basic building blocks of living things. Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues?, which in turn group together to form organs?, such as the heart and brain.
How do cells know what to do?
| The human genome contains 30,000 genes, but only a subset is expressed in each cell. Through gene expression, transcription and translation of this subset of genes determines how a cell looks and acts—its phenotype. | Cell fate means that a stem cell “makes a decision” to differentiate into a more mature cell type.
How do we keep your cells healthy?
Antioxidants — such as vitamins C and E and carotenoids, which include beta-carotene, lycopene and lutein — help protect healthy cells from damage caused by free radicals.

What goes into a cell?
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Metabolic processes in animals and plants usually require oxygen, which is in lower concentration inside the cell, thus the net flow of oxygen is into the cell.
What are the different types of cells and their functions?
Some of the cells are like Mitochondria, ER or Endoplasmic Reticulum, Golgi complex, Lysosomes, and Peroxisomes. There are the different types of human cells and their functions will be discussed. Mitochondria, it is also known as the ‘power plant’ because it is the powerhouse of the cells.
How does the body identify its own cells?
The immune system must distinguish between self and non-self cells so that they are able to identify cells belonging to the body and foreign cells that need to be attacked. The immune system co-exists with all the cells in the body without attacking them due to the cells have MHC markers enabling the immune system to identify these cells as belonging to self.
How does the body produce new types of cells?
New cells are created from a process called cell division. The new cells are produced when a cell, called the mother cell, divides into new cells called daughter cells. When two daughter cells have the same number of chromosomes as the original cell, the process is called mitosis.
What do blood cells carry to your body?
among a range of other vital functions.
