Active transport | the movement of materials from low to high concentration. It takes energy from the cell. |
Cell membrane | flexible layer around all cells |
cell wall | non-living boundary layers around plant cells |
centrolies | helps animal cells with cell division |
chloroplasts | green organelles in plant cells that carries on photosynthesis |
cytoplasm | jelly-like substance inside cell |
chromosomes | a strand of genetic material made up of jenes |
diffusion | the movement of materials from high to low concentration |
er (endoplasmic reticulum) | organelles that helps transport materials in the cell |
Osmosis | movement of water in or out of cell |
Passive transport | movement of materials in or out of cells |
mitochondria | powerhouse of the cell |
mitosis | cell division / cell dividing into 2 |
nucleur membrane | a double layer around nucleus |
nucleus | control center of cell |
passive tranport | when materials flow from high to low concentration through membrane and does not use any energy |
ribosomes | organelle that makes protein |
vacuoles | stores food, water, or waste from cell |
nucleolus | small body in nucleus |
lysosomes | breaks down food and destroys foreign substances |
