  2. Prophase - Wikipedia

    en.wikipedia.org/wiki/Prophase

    Arabidopsis thaliana cell in preprophase, prophase and prometaphase. Preprophase band is present along the cell wall from images 1–3, is fading in image 4, and disappears by image 5. [1] The most notable difference between prophase in plant cells and animal cells occurs because plant cells lack centrioles.

    However, side products are considered waste and removed from the cell. [2] Different metabolic pathways function in the position within a eukaryotic cell and the significance of the pathway in the given compartment of the cell. [3] For instance, the electron transport chain and oxidative phosphorylation all take place in the mitochondrial membrane.

    The Green Salt Plant, the common name for Plant 4, produced "green salt" (uranium tetrafluoride) from UO 3. Green salt was the key intermediate compound in the overall process of producing uranium metal. This plant contains 12 banks of furnaces for the conversion of uranium trioxide to uranium tetrafluoride.

    They regulate cell functions including proliferation, gene expression, differentiation, mitosis, cell survival, and apoptosis. [1] MAP kinases are found in eukaryotes only, but they are fairly diverse and encountered in all animals, fungi and plants, and even in an array of unicellular eukaryotes. [citation needed]
