Answer:
Photosystem II is the first link in the chain of photosynthesis. It captures photons and uses the energy to extract electrons from water molecules. ... First, when the electrons are removed, the water molecule is broken into oxygen gas, which bubbles away, and hydrogen ions, which are used to power ATP synthesis.
Answer:
Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
Explanation:
it has a nucleus membrane bound organelle like endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria
In a prokaryotic division, the cellular reproduction
is by binary fission. The bacterial chromosomes replicate then proteins migrate
toward the midpoint of the cell and the duplicated chromosomes moves away from
each other forming a protein ring at the midpoint. Plasma membrane and cell
wall materials will accumulate to add to the cell volume. Then, the protein
ring will form a septum that pinch inward and divide the cell in two, forming
two daughter cells.
