Cell Organelles and Scientists
| Question | Answer |
|---|---|
| Eukaryote | an organism with cells having a true nucleus as well as membrane bound organelles |
| Prokaryote | an organism with cells lacking a true nucleus and membrane |
| Eu | true |
| Pro | before |
| Cytoplasm | consists of everything within the cell membrane except the nucleus |
| Cytoskeleton | a system of fibers in the cytosol that helps maintain the cells shape/ provides protein motors |
| Flagella | an extension of the cytoskeleton; propels the cell |
| Nucleoid | found in prokaryotes, contains the genetic material for the cell |
| Capsule | found in bacteria outside the cells membrane and cell wall, protects the cell |
| Ribosome | found in prokaryotes and Eukaryotes, contains proteins and RNA |
| Chloroplast | pigmented plastid, found in plants and algae, converts light energy from the sun into chemical energy |
| Leucoplast | colorless, stores starches, lipids, amd proteins |
| Cell wall | provides strength and rigidity to the cell, materials pass through its pours |
| Central vacuole | stores water, salts, sugars, and proteins, keeps cell rigid |
| Granum | made of stacks of thylakoids, contain the green pigment chlorophyll to cary out photosynthesis |
| Rough endoplasmic reticulum | transports compounds around the cell, helps maintain the cells shapes |
| Nucleus | controls the actions of the cell/ contains genetic material |
| Chromatin | contains DNA, RNA, and proteins |
| Cell membrane | protects the cell/ allows certain materials to move through it |
| Lysosome | disgusts food, kills bacteria, recycles old cell parts |
| Modern cell theory | cells are the structural and functional units of all living things |
| Hooke | named cells |
| Schwann | said that all animals are made up of cells |
| Schleiden | said that plants are plants are made up off cells |
| Virchow | cells come from cells |
| Unicellular organisms | organisms that are made up of one cell, Ex: bacteria,protons |
| Colony | unicellular organism that work together |
| Multicellular organisms | made of 2 or more cells that depend on each other to function tissues |
| tissues | cells that join together |
| Organs | tissues that work together to perform a specific function |
| Organ System | a group of organs that work together |
| Organelle | A structure found within the cytoplasm of a cell that performs a specific set of functions in a cell that the cell needs to stay alive. |
| Centrosome | builds part of the cytoskeleton (animals,humans) |
| Cilia | propels the cell through its environment, moves particle past the cell, moves out of the lungs and into the throat |
| Lipid bilayer | A structure based on lipids having a hydrophilic end and a hydrophilic end, arranging themselves into two layer |
| Golgi apparatus | receives substances from the ER and packages then into membrane sacs called resides |
| Mitochondria | powerhouse of the cell, transforms energy from sugars into usable energy for the cell |
