Mathoscience 42 Contributions Is photosynthesis performed by all plants? Most of the removed electrons and hydrogen ions ultimately are transferred to carbon dioxide CO2which is reduced to organic products.
Just did this lab in Biology. For advanced microscopy, such as fluorescence microscopy, the layers halfway between the outside and the centre of the onion are best. Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.
