who founded cell theory & who founded our classification system
cell theory:
1.
2.
3.

Explanation:

1. Cell: The basic unit of life. All living organisms are made up of cells, which can be single - celled (unicellular) or multi - celled (multicellular).
2. Unicellular: Organisms consisting of a single cell, like bacteria and some protists. They perform all life functions within that one cell.
3. Multicellular: Organisms made up of many cells. These cells can be specialized to perform different functions, such as nerve cells, muscle cells in animals or xylem and phloem cells in plants.
4. Cell theory: States that all living organisms are composed of cells, cells are the basic unit of structure and function in living things, and new cells are produced from existing cells. It was founded by Matthias Schleiden, Theodor Schwann, and Rudolf Virchow.
5. Taxonomy: The science of classifying organisms. It arranges organisms into a hierarchical system of groups such as kingdom, phylum, class, order, family, genus, and species.
6. Kingdom: The highest level of taxonomic classification. Examples include Animalia, Plantae, Fungi, Protista, and Monera.
7. Phylum: A taxonomic rank below kingdom. For example, Chordata is a phylum in the animal kingdom which includes vertebrates.
8. Class: A rank below phylum. In the Chordata phylum, classes include Mammalia (mammals), Aves (birds), etc.
9. Order: Below class. For example, in the Mammalia class, Primates is an order.
10. Family: Below order. For example, in the Primates order, Hominidae is a family.
11. Genus: Below family. For example, in the Hominidae family, Homo is a genus.
12. Species: The most specific taxonomic rank. A group of organisms that can interbreed and produce fertile offspring. For example, Homo sapiens is the species of modern humans.
13. Scientific name: Composed of the genus and species name, written in Latin. It is unique for each species and provides a universal way to identify organisms.
14. Biblical kind: A concept from a creation - based perspective, not a scientific taxonomic term. It is thought to represent a group of organisms that were created separately and can vary within that kind.

The 6 characteristics of life are: 1. Organization (cells are the basic unit of organization), 2. Metabolism (the sum of all chemical reactions in an organism), 3. Growth and development (organisms grow and change over time), 4. Response to stimuli (react to changes in the environment), 5. Reproduction (produce offspring), 6. Homeostasis (maintain a stable internal environment).
The classification system was founded by Carl Linnaeus.

Answer:

1. Cell: The basic unit of life.
2. Unicellular: Single - celled organisms.
3. Multicellular: Organisms with many cells.
4. Cell theory: All living things are made of cells; cells are basic units of life; new cells from existing cells. Founded by Schleiden, Schwann, and Virchow.
5. Taxonomy: Science of classifying organisms.
6. Kingdom: Highest taxonomic rank.
7. Phylum: Rank below kingdom.
8. Class: Rank below phylum.
9. Order: Rank below class.
10. Family: Rank below order.
11. Genus: Rank below family.
12. Species: Most specific taxonomic rank.
13. Scientific name: Genus and species name in Latin.
14. Biblical kind: Creation - based concept.

The 6 characteristics of life: 1. Organization, 2. Metabolism, 3. Growth and development, 4. Response to stimuli, 5. Reproduction, 6. Homeostasis.
Cell theory founders: Schleiden, Schwann, Virchow.
Classification system founder: Carl Linnaeus.
