Question | Answer |
cell theory 1 | all living things are made of cells |
cell theory 2 | cells are the basic unit of life |
cell theory 3 | all cells come from pre-existing cells |
Hooke | named cells |
Van Leuwenkoek | discovered single-cell animal like arganisms |
Schleiden | studied plant cells |
Schwann | determined that all animals are made of cells |
Virchow | all cells come from pre-existing cells |
Redi's experiment | theory that maggots are not born from rotting meat- they come to it to nurse babies and eat the flesh |
cellular transport formula | PEEDO- LLLHH |
diffusion | no energy-high to low-movement of substances (not water)-moves down a concentration gradient |
protein pumps | energy-low to high-transport proteins that require energy to work-changes shape to move molecules |
osmosis | no energy-high to low-diffusion of water across a selectively permeable membrane-balances out water across membrane |
endocytosis | energy-low to high-taking bulky materials into a cell-cell membrane folds in around food particle |
exocytosis | energy-low to high-forces material out of a cell in bulk-membrane surrounding the material fuses with cell membrane |
active transport | energy required |
passive transport | no energy required |
cellular respiration formula | oxygen+glucose>water+carbon dioxide+energy/atp
plant and animal cells-OGWCE
organelle responsible- mitochondria |
photosynthesis formula | WATER+carbon dioxide+sun>oxygen+glucose
plant cells
organelle responsible- chloroplast |
diploid | having 2 copies of each chromosome (2n) |
haploid | Having 1 copy of each chromosome (1n) |
gamete | a reproductive cell that has only 1 set of chromosomes (1n)
example: sperm / egg |
chromatids | duplicated DNA- when it breaks into two 2 |
chromosome | singular, non daugher |
