FC: Biology: Information About Cells | Cole Miller & Griffen Fry
1: 1.All living things are made of cells. 2.Cells are the basic units of life. 3.Cells come only from other cells. | Three Principles of Cell Theory
2: Robert Hooke created the first microscope and used it to look at cork cells. We use microscopes to look at things unseen by the naked eye. | Rudolf Virchow is Known as the “Father of modern pathology”. He was the leader of medicine and pathology in the 19th century. His biggest achievement was his observation that a whole organism does not get sick, only certain cells or groups of cells.
3: Matthias Schleiden concluded that all plant tissues contain cells. He declared that the cell is the basic building block of all plant matter. This was the first generalization concerning cells. | Theodor Schwann concluded that animal tissue is composed of cells, but that plant and animal cells are of different structure. He stated that cells are organisms and all organisms consist of one or more cells. He also concluded that cells are the basic unit of life, this was the 2nd generalization concerning cells and considered the most important in the start of biology.
4: Prokaryotic cells are unicellular. They were the first living thing on the planet, around 3.5 billion years ago. They are most commonly bacteria. | Prokaryotic
5: Eukaryotic | Eukaryotic cells are cells that evolved from prokaryotic cells. They can be multicellular or unicellular. Things like dogs, trees, shrubs, and even you, are made of eukaryotic cells.
6: Plant Cell | Plant cells contain several things that animal cells do not have, including: Vacuoles, a rectangular shape, Cell wall, chloroplast and it's larger than an animal cell. | V
7: Animal Cell | Animal cells also have a few differences, including: centrioles, lysosomes, a circular shape, and a smaller size than a plant cell. | S.
8: Chloroplasts | Chloroplasts are found only in plant cells. They hold the chlorophyll for the plant, which | is why they are green. The plants photosynthesis takes place here.
9: Mitochondria | Mitochondria are the "power-house" for the cell. They make sugars along the inner membrane. | The folds that are on the inside allow for more surface area, so that the organelle can produce more energy.
10: Central Vacuole | A large sac inside the cell, it helps with intracellular digestion. It is mostly made up of water. It is very large in plant cells and, when supplied with water, provides structure.
11: Golgi Apparatus | The golgi apparatus or golgi body, is important for packing macromolecules (very large, complex molecules) so that they can be transported throughout the cell. | Golgi Apparatus macromolecule
12: Lysosomes | Lysosomes are small spheres inside the cell. They hold, and transport enzymes throughout the cell, and between other cells. They are more common in animal cells than in plant cells.
13: Cell Wall | The cell wall is the outer layer of a plant cell that provides the cell with protection and structure. It is used to prevent too much water from going into the plant cell and over filling the plant cell. | Cell Wall---->
14: Ribosomes | Ribosomes are the organelles where the cell assembles proteins according to its genetic instructions. Ribosomes can bind to endoplasmic reticulum and make proteins that are exported to other cells.
15: Nucleus | The nucleus is specific to only eukaryotic cells. It's the main sphere in the middle of the cell that is used to hold DNA. It is encased in a double membrane called the nuclear envelope.
16: Flagellum | The flagellum is the tail-like thing on the end of a cell that allows the cell to move around. It is most commonly found on a eukaryotic cells.
17: Endoplasmic Reticulum | Endoplamic reticulum is a eukaryotic organelle that is connected to the nuclear envelope and is used to store enzymes and give them a place to do their actions. | Smooth ER--->
18: Cell Membrane | The cell membrane is what encloses the cell. It is a double layer of lipids (fats) and has pores to allow things to pass in and out of it.
19: an up close view of the cell membrane. <----- | The cell membrane surrounds the cell. ---------->
21: Homeostasis is the level of balance and equilibrium within an organism. At all times, every organism is attempting to reach homeostasis. Your body trying to reach homeostasis is what causes you to respond to things the way you do.
