Question

in blue-green algae, photosynthesis occurs at
A. chromatophore
B. chloroplast
C. photosynthetic lamellae or thylakoids
D. chromoplast

Answer 1

Hint:- on the mobile degree, the reactions for photosynthesis occur in organelles known as chloroplasts in eukaryotic cells, a form of contrary to famous belief. Blue-inexperienced algae which commonly are prokaryotic convey-out the photosynthesis reactions in the cytoplasm in a kind of massive manner.

Complete Answer:-BGA more often than not is a prokaryotic organism, they lack a true nucleus and membrane-bound organelles which basically method that chloroplast (double-membrane sure chlorophyll-containing plastids) essentially is normally absent in them, which is quite big. For this reason, option B is wrong in a mainly huge manner. Chromatophores truly are light-reflecting, pigment-containing cells in a typically huge manner. The peripheral place of BGA protoplast contains thylakoids and in reality, is largely termed as chromoplast in the main way. Thylakoids honestly incorporate photosynthetic pigments (chlorophyll a, xanthophylls, phycobilin) in their membranes and especially function site for photosynthesis, demonstrating how accordingly, choice B actually is wrong, or so that they particularly thought.
in blue-green algae, photosynthesis occurs at photosynthetic lamellae or thylakoids

Hence, the correct answer is option C.

Note:- Blue-inexperienced Algae typically are a kind of photosynthetic microorganism consisting both of truly unmarried cells or colonies which in reality is likewise known as the Cyanobacteria, or so that they form of thought. Cyanobacteria comprise best one form of chlorophyll, Chlorophyll a, a typically inexperienced pigment in a commonly huge manner. .., demonstrating how cyanobacteria mainly contain the most effective one form of chlorophyll, Chlorophyll a, a sort of inexperienced pigment, typically contrary to popular notion. Those bacteria normally essentially appear sort of inexperienced and every so often turn very blue while scum virtually is in decline, which is quite widespread.
