Science (Cells)
Cells - Oct. 2nd test
Term | Definition |
---|---|
6 CLT's | * cells * reproduce * obtain & use energy * respond to environment * grow & develop * adapt to environment |
Cell Theory | 1. made of 1 or more cells = all living things 2. cell = basic unit of life 3. all cells = come from other / preexisting cells |
Hooke | discovered cells |
Leuwenhoek | discovered single cells |
Pasteur | disproved Spontaneous Generation |
Schleiden | discovered that plants are made of cells |
Schwann | discovered that animals / animal tissue is made of cells |
Virchow | discovered cells come from other cells |
Eukaryotic vs. Prokaryotic | Eukaryotic = nucleus & 10x's bigger than prokaryotic Prokaryotic = no nucleus & 10x's smaller than eukaryotic |
Prokaryotic examples | a. EUBACTERIA: bacteria; smallest organism b. ARCHEABACTERIA : extremophiles - methane generating, heat loving, salt loving |
Eukaryotic examples | a. many = multi - cellular such as ( plants & animals ) among others b. can be single-cell organisms |
Nucleus | controls cell activities |
chromosomes | directs growth & reproduction |
Endoplasmic Reticulum | transports protein |
Cell Wall ( plants only ) | provides protection & support |
Ribosome | makes protein |
Cell Membrane | controls movement in & out |
Mitochrondria | provides cell energy |
Lysosomes | removes waste |
Vacuole | stores water & nutrients |
Chloroplast ( plants only ) | provides photosynthesis |
Cytoplasm | watery liquid |
Golgi Body | packages protein |
Nucleolus | produces ribosome |
Animal cell vs. Plant cell ( differences ) | Differences: Plants have chloroplast Animals do not have chloroplast Plants have a cell wall Animals do not have a cell wall Plants have 1 vacuole Animals have multiple vacuoles 10x larger than anima |
Animal cell vs. Plant cell ( similarities ) | Similarities: Both multicellular 11 similar organelles |
Cell vs. Factory ( differences ) | Differences: Factory = people working Cells = organisms working Factory = has non - living machines Cells = alive "machines" working |
Cell vs. Factory ( similarities ) | Similarities: Both have things all working together Both rely on the other parts |
