Science (Cells)

Cells - Oct. 2nd test

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
