Initially, when scientists were first using the taxonomy system to classify living organisms there were only considered to be 2 kingdoms: plants and animals. However, when the microscope was invented, scientists were able to observe differences in organisms at the cellular level! They were also able to observe microscopic living organisms like bacteria that they had not been able to observe before. Scientists realized it was necessary to add 4 new kingdoms to account for the observations they had not seen before the invention of the microscope.

A eukaryotic cell can replicate itself two ways. Hope this helps!
Answer:
1: Light-dependent reactions:
Reactants: H2O, ADP, NADP
Products: O2, ATP, NADPH
Location: Thylakoid membranes of chloroplasts in cells of leaves
2: Light-independent reactions
Reactants: CO2, H2O, ATP, NADPH
Products: C6H12O6 (glucose), ADP, NADP
Location: Stroma of chloroplasts in leaf cells
Explanation:
Photosynthesis takes place in two stages:
1: Light-dependent reactions: This stage includes splitting of water in the presence of sunlight and release of electrons and oxygen gas. The electrons are channeled into the electron transport chain and result in the formation of ATP and NADPH. This stage includes photosystem I and II present in the thylakoid membrane. Hence, light-dependent reactions of photosynthesis occur in the thylakoid membrane of chloroplasts and form ATP and NADPH.
2: Light-independent reactions: Also called as Calvin cycle, the light-independent reactions use ATP and NADPH formed during light reactions of photosynthesis to fix CO2 into glucose. The enzymes of the Calvin cycle are present in the stroma of chloroplasts and hence, this stage of photosynthesis occurs in the chloroplast stroma.
