Jul 27, 2023 · The image below shows a detailed timeline that led to the discovery of cell and the cell theory: Cell Theory Timeline. The Three Parts of the Cell Theory. According to the conclusions made by Schleiden and Schwann in 1838, it was proposed that: All living things are composed of one or more cells.
8 months ago. what you actually need to learn from this video: 1. Robert Hooke coined the term cell. He was inspired by monks rooms, which were called cells. 2. the modern cell theory is composed of three facts: a)all life is composed of one or more cells, b)a cell is a basic unit of life, and, c)all cells come from other cells. Hope this helps :)

- What is GERL system and what is the need?ER -> Golgi bodies -> Lysosome. Many needs.... 1. intracellular digestion 2. mobilization/transport of secretory products 3. membrane biosynthesis
- how do we estimate how many cells we have? I mean there's so many!This could be one way: calculate how many cells are in one area (maybe per cubic cm) and then multiply by the total volume

- What was the feud between Newton and Hooke ?They had beef because both claimed credit for coming up with the law of universal gravitation.
- How many cells do people have?estimated to be about 30 trillion
- if an organism is composed of only 2 cells , will it be called diploid or a multicellular organism ?A diploid cell is a cell containing two sets of chromosomes where one set is inherited from each parent. It has nothing to do with the size of an o...
- Aren't cells made up of atoms? So doesn't that make atoms the basic uniits of life?Cells are made of atoms (everything is), but cells are alive and atoms are not, so cells are the basic units of life. Lots of stuff made from atoms...
Explain the contributions of Semmelweis, Snow, Pasteur, Lister, and Koch to the development of germ theory; While some scientists were arguing over the theory of spontaneous generation, other scientists were making discoveries leading to a better understanding of what we now call the cell theory. Modern cell theory has two basic tenets:

The ideas of all three scientists — Schwann, Schleiden, and Virchow — led to cell theory, which is one of the fundamental theories unifying all of biology. Cell theory states that: All organisms are made of one or more cells. All the life functions of organisms occur within cells. All cells come from already existing cells.
Jan 21, 2020 · While some scientists were arguing over the theory of spontaneous generation, other scientists were making discoveries leading to a better understanding of what we now call the cell theory. Modern cell theory has two basic tenets: All cells only come from other cells (the principle of biogenesis).
Feb 10, 2022 · Modern cell theory has three basic tenets: All organisms are made of cells. All cells only come from other cells (the principle of biogenesis). Cells are the fundamental units of structure and function in organisms. Today, these tenets are fundamental to our understanding of life on earth.
The Cell Theory consists of three key principles: Every organism is comprised of one or more cells. The cell is the most basic unit of life. All cells are derived from preexisting cells. Through further scientific investigation of cells over the ensuing centuries, scientists have also discovered that all cells share other properties, including:
