1: Theodor Schwaan published conclusions that expressed the principle of cell theory. Theodore Schwann published a plants and animal cells book in 1839. Mathais Schleiden and Theodore Schwann actually worked together to create the three principles of cell theory. When Shleiden advanced the pant cell theory for plants, Schwann | Theodore Schwann wanted to extend it to animals. His contribution to the cell theory was he concluded that all animals are made up of cells. Schawann studied the muscle contraction and nerve structure.
2: Hooke was the first first person to look through a microscope and see a cell. He was the person who gave the cell its name. | Virchow was the first to demonstrate that the cell theory applies to diseased tissue as well as to healthy tissue-that is, that diseased cells derive from the healthy cells of normal tissue. | Mathias Schleiden declared that the cell is the basic building block of all plant matter. Schleiden viewed the plants under a microscpe. He is considered to be the co-founder of cell theory together with Schwann.
3: The Three Principles of Cell Theory 1. The cell is the unit of structure, physiology, and organization in living things. 2. The cell retains a dual existence as a distinct entity and a building block in the construction of organisms. 3. Cells form by free-cell formation, similar to the formation of crystals.
4: What is the Difference between Prokaryotic and Eukaryotic Cells? | Prokaryotic DNA is linear No Nucleus contains no chromosones lack some organelles unicellular Ribosomes are small reproduction only asexual | Eukaryotic DNA is circular Has a nucleus contains chromosones do not lack any organelles multicellular ribosomes are large asexual or sexual
5: Animal Cell vs Plant Cell | Animal Centrioles round shaped cant create there own food | Plant Cell Wall Chloroplasts Square Shaped make their own food
6: Ten Cell Structures | Nucleus The nucleus is the brain of the cell. Membrane enclosed organelle found in the eukaryotic cells. | Cell Wall The cell wall is the cell shape, strength, and protection, and pressure. | Cilia The cilia is a hair like structure that helps move liquid past the surface of the cell. | Mitochondria The bronchial process of respiration and energy production occur.
7: Chloroplast chloroplast are specialized organism found in all higher plant cells. they contain the plants chlorophyll which makes them green. | Ribosome Cell organelle composed of protein synthesis is cellular structures. | Central Vacuole found in plant cell that is used to digest food and contains food. | Eukaryote Eukaryote is an organelle whose cells contain complex structures enclosed within membranes | Flagella is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells
8: Homeostasis The ability of a system or living organism to adjust to its natural habitat to maintain a stable equilibrium. Such as the ability of warm-blooded animals to maintain a constant body temperature. Maintaining a stable natural environment requires constant monitoring and adjustments as the environment changes. Homeostasis helps the body to adapt to its surroundings.
9: Cell Membrane The cell membrane is made up of protein and phospholipids. Phospholipids is a lipid containing a phosphate group in its molecule. The cell membranes job for the cell is to decide what comes in and what comes out. The cell membranes job is important because if the wrong stuff comes in it could damage the cell.
