Question

A mutant plant lacking the ability to pump protons out of leaf companion cells will be unable to do which of the following?
a. initiate transpiration
b. load sucrose into sieve-tube elements
c. carry out photosynthesis
d. transport water through the xylem

Accepted Answer

Hello everyone and welcome to today's video. So companion cells are blank and regulate the activities of blank seek to cells. And these question relates to whether these cells are nuclear hated, multi nuclear hated or eaten nuclear rated. Which means that they lack a nucleus. So let's think about it in this way recall from previous videos what the function of the C. Two cells are and the function is to transport certain nutrients or to transport water because they have to transport things. They're usually going to be hollow, meaning that they have nothing inside. So these nutrients can pass through without any organelles getting in the way because of this they're going to lack most organelles including a nucleus so their nuclear waited or they lack a nucleus. However these companion cells have to load up these seeds to cells with the nutrients that they're going to be carrying or transporting because of this. They have to metabolize and work with these nutrients so that they are ready for transport when they load them up into the seats to cells because they have to metabolize them. They need certain organelles so they will have organelles including a nucleus because of this they are nuclear ated. So companion cells are nuclear hated and regulate the activities of nuclear hated C. Two cells. This is going to be represented by answer choice C. And we will highlight as the final answer to our question. I really hope this video helped you and I hope to see you on the next one
