BC: It's the little things that make life beautiful.
FC: By: Kenlierushi | All About Cells
1: Cell Theory!!!:) | 1. All living things are made of one or more cells. 2. Cells are the basic unit of structure and function in organisms. | 3. All cells arise from existing cells.
2: Robert Hooke: Discovered cells on a piece of cork and was credited for finding the basic unit of life. | Scientists
3: Rudolph Virchow: Suggested that all cells come from pre-existing cells.
4: Friends are Flowers that Never Fade | Matthias Schleiden: Proposed that all plants are composed of cells.
5: Theodor Schwann: Discovered all animals are made of cells. Together, Schleiden and Schwann's ideas contribute to the cell theory: all living things are made of cells.
6: Eukaryotic Cell | A cell that contains membrane-bound compartments in which specific metabolic activities take place. Most important among these compartments is the nucleus, which houses the eukaryotic cell's DNA. Eukaryotic organisms also have other specialized, membrane-bounded structures, called organelles, which are small structures within cells that perform dedicated functions. Eukaryotic cells are typically 10 to 100 micrometers across, or about 10 times the size of prokaryotic cells. Examples: animals, people, plants.
7: Prokaryotic Cells | Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. These cells have few internal structures that are distinguishable under a microscope. Examples of prokaryotic cells: E. Coli Bacteria, Salmonella Bacteria, and Bacillius Bacterium.
8: Animal Cells | -They have more of a round shape and are specialized to fit the functions of animals and humans! Organelles in the cell include: -Cell membrane -Mitochondria -Nucleus -Rough E.R -Smooth E.R. -Golgi Apparatus -Lysosome -Vacuoles -Ribosomes This is a eukaryotic cell.
9: Plant Cells | Plant cells are more adapted to a plant's function and needs. They are more square in shape. Although they have the same organelles as animal cells, they have some more of them with specialized functions. They have a cell wall which gives them structure and support as well as chloroplasts which help in photosynthesis.. They have a central vacuole too which holds more fluid.
10: Lysosome- Cleans up the waste in the cell Ribosome- Makes proteins Mitochondria- Makes ATP energy | Lysosome | Ribosome | Mitochondria
11: Cell Wall- Supports and gives structure to plant cells Smooth ER- it detoxes the cell Rough ER- Modifies proteins | Cell Wall | Smooth ER | Rough ER
12: Nucleus | Nucleolus | Golgi Apparatus | Cytoplasm | Nucleus: contains genetic information (DNA) and controls organelles functions. Nucleolus: stores ribosomes Golgi Apparatus: packages and ships proteins Cytoplasm:holds organelles together
13: Cell Membrane | It separates the internal environment from the external environment.It also controls what comes in the cell and what goes out. They use passive transport without energy and active transport with energy. It is a semipermeable membrane. (selectively permeable)
14: Homeostasis | Homeostasis tries to achieve a balanced internal environment. For example, the cell membrane protects the cell from outside stimuli that can disrupt homeostasis. The nucleus helps to regulate the functions of other organelles to adapt to certain changes.
