BC: The End
FC: By: Roy Park and Alvin Abraham | All About the Cell
1: Life brings simple pleasures to us every day. It is up to us to make them wonderful memories. CathyAllen | Cell Theory | The cell theory also know as the cell doctrine says that all living organisms are made up of the same basic structure, called a cell. The cell is a structural and functional unit of living things. All cells are made up of spontaneous generation, meaning they come from pre-existing cells. All cells contain hereditary information which is passed from cell to cell. All cells are the same when it comes to is composition. The energy flow occurs in the cell.
2: Prokaryotic V.S. Eukaryotic Cells | The main difference between the two cells is that the eukaryotic cell has a nucleus. Also their DNA is different. The eukaryotic cell's DNA is linear while the prokaryotic''s is circular. Also the eukaryotic cell is a lot more complex than the prokaryotic.
4: Robert Hooke- the first to discover that all living things are made up of cells. He first examined a piece of cork and noticed the different chambers in it.. He however thought that cells only exist in plants. Theodore Schwann- formed the cell theory with the help of Matthias Schleiden, after discussing the structure of a plant cell, He compared that to what he knew about the animal cell to form the cell theory. | Famous Scientists | Robert Hooke | Theodore Schwann
5: Famous Scientists | Matthias Schleiden- Shared his knowledge of the plant cell with Theodore Schwann in order to form the cell theory. He then extended what Schwann had written by adding to the idea of spontaneous generation. Anton Von Leeuwenhoek- used his single lens microscope to be the first man to examine bacteria, and protozoa. He is also known for making microscopes. He was the first to discover red blood cells and live sperm cells of animals. | Matthias Schleiden | Anton Von Leeuwenhoek
6: All things grow better with love. | Animal V.S. Plant Cells | Plant and animal cells have lots in common but they have key differences. One is that the plant cell has a cell wall, while the animal cell doesn't. Also the plant cell's vacuole is much bigger. Takes 90% of the plant cell's volume. They also have chloroplasts for photosynthesis, because animals don't make their own food animal cells don't have chloroplasts. And finally the plant cell is a rectangular shape due to the cell wall, and the animal cell is round.
8: Cell Structures | Nucleus- A cellular organelle that exists only in eukaryote cells. One of the most important organelles, because it processes the information and administrative center of the cell Nucleolus- A small spherical body in the nucleus of a eukaryote cell, made up of mostly proteins and RNA. This organelle forms ribosomes when the chromosomes of the DNA extend into the nucleolus. Nuclear Membrane- made up of two layers, which are made of lipids. This thin barrier regulates and exchanges material in and out of the cell. Smooth ER- formed of small tubules and vesicles. Allows for more surface area to store key enzymes and the product of these enzymes. It also synthesizes lipids and steroids.
9: Rough ER- Composed of sealed sacs that extend to the cell membrane. It synthesizes proteins. Mitochondria- the main purpose is to produce ATP, which carries energy to cellular processes. Chloroplast- Where photosynthesis occurs. Golgi Apparatus- major role is to store and sort proteins and lipids. Peroxisomes- Contains enzymes that help break down amino and fatty acids. Lysosomes- to degrade macro molecules within the cell. These only exist in animal cells. Ribosomes- the organelle serves a protein production machinery for the cell and are consequently most addundant on cells with alot of proteins. | Cell Structures
10: Cell Membrane | The cell membrane is important because it helps a lot with the cells ability to maintain homeostasis. The cell membrane acts as a barrier to the cell blocking harmful substances from the cell's organelles. But it also lets in good substances needed for the cell to maintain homeostasis and do its job.
11: Homeostasis is when a body of complex organisms works together as a system to keep internal stability. The cell tries to keep homeostasis by using all the organelles it has. The cell membrane plays a big role in homeostasis because it lets in chemicals the cell needs and repels the ones that it doesn’t need in order to keep the cell stable. It acts as a barrier to the cell so it will not be harmed. It also keeps the chemicals it needs. The other organelles help by doing its job to keep the cell stable, like making ribosomes and lysosomes to produce energy. | Homeostasis
