The true statement about the relationship between true moss sporophytes and gametophytes is: (d) Sporophytes are parasites of gametophytes.
Sporophyte is the part of the life cycle in plants where the plants are asexual and in diploid phase of their life. The plants produce spores during this stage. In vascular plants sporophyte is the dominant stage of life.
Parasites are the organisms that live inside or outside an organism and depend upon that organism for their food as well. Apart from extracting food, the parasites also provide some kind of harm to the host they live in. Sporophytes are called parasites because they directly developed from the fertilized egg in archegonia.
The given question is incomplete, the complete question is:
Considering that the mature sporophytes of true mosses get their nutrition from the gametophytes on which they grow, and considering these generations as individual plants, what is true of the relationship between true moss sporophytes and gametophytes?
a. Sporophytes are endosymbionts of gametophytes.
b. Sporophytes are mutualists of gametophytes.
c. Sporophytes are commensalist of gametophytes.
d. Sporophytes are parasites of gametophytes.

Answers:
#1:
The process that takes place in the stroma in both sunlight and darkness is the Calvin cycle. In sunlight and darkness the Calvin cycle produces a light dependent reaction which then produces ATP and NADPH. Even in darkness the process will still be able to undergo completion. If it has been dark for too long there will not be enough ATP and NADPH to continue sugar production.
#2:
Pyruvate: If there is any oxygen molecules produced in glycolysis will be passed to the Kreb cycle but when there isnt enough oxegen the transport chain wont run which mean fermentation will occur since the NADH molecules have nowhere to go.
NADH: Will go into electron transport.
ATP: Stores energy for a period of time.
#3:
Mitosis and cytokinesis both go through cell division and during mitosis chromatis divides into daughter cells meanwhile cytokinesis has one cell split into two. Without cytokinesis, mitiosis would still happen but only create two nucli in one cell and if cytokinesis happens the cell would die.
It should be the second one it sounds very familiar.
