Question

Some toxins prevent cells from absorbing water. Cells that are affected by these toxins are unable to carry out many of their normal functions. Which of these organelles would be most directly harmed by one of these toxins? * 5 points ribosomes endoplasmic reticulum chloroplasts mitochondria

Answer 1

Answer:

Chloroplast

Explanation:

This is because in the  first stage of photosynthesis(light dependent stage) i  water molecules is spilt  by sunlight absorbed by chlorophyll- Photolysis into  H+  and electrons, with Oxygen.

It is the H+ from above that is used to reduce CO2 in the light independent stage, as the Calvin Cycle, to produce Glucose, fatty acid, and protein.

Therefore in absence of water, absorption   by the xylem due to inhibition by toxin, Photosynthesis is INHIBITED.Since no H+ is produced.
