Hi, I'm Laura, Professor of Science. I will tell you about cells and their functions
The cell is a structure consisting of three basic elements: plasma membrane, cytoplasm and genetic material (DNA). Cells have the ability to perform all three vital functions: nutrition, relationship and reproduction (see t13)
The shape of the cells is basically determined by their funcion..The size of the cells is also extremelly variable.
This is the cell
now we are going to see a cell from the microscope
this cell is eucariota,these cells have three distinct parts:the membrane,which surrounds it;the cytoplasm,which fills a large part pf the cell and where organelles work, and the nucleus where the genetic information of the cell is found.
One of the most important characteristics of the cell is its two types: Unicellular cells: Its body is constituted by a single cell, which performs all the functions of a living being
