Imagine that you have developed a drug that prevents photosystem I -- but NOT photosystem II -- from absorbing light energy. What effect would this have on a plant cell? Pick an option The cell would stop producing NADPH, and therefore stop fixing carbon dioxide.

The cell would stop producing NADPH, and therefore stop oxidizing glucose.

The cell would no longer be able to generate a proton gradient in the chloroplast, and therefore the lumen's pH would become lower.

The cell would no longer be able to generate a proton gradient in the chloroplast, and therefore would need more ATP from the mitochondria.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

bacterium is not correct

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
