Fruits and Nuts: Wild Strawberries HELP!, 0 by Izumi

Thank you so much for your help! I greatly appreciate it. Your advice has generated a few new questions in my mind, though. I'm not a very experienced cultivator from seed, so forgive me if I don't understand the basics.

If I put a sealed plastic bag around the plant, how often should I water it? Will it still get enough carbon dioxide to survive for several days, or do I need to open the bag periodically to replenish the air? I could put the plant in a north window that is somewhat shaded (light filters through large trees outside), or in an east window that is less shaded, but which gets direct sun only in the morning. Which do you think would be best? And, by the way, do you think I should repot it now, or give it a chance to stabilize first?

I'm attaching a photo of the plant in its current state. What do you think; does it have a chance? Any ideas about the brown on the tips of the new sprout?

Many, many thanks for your helpful suggestions.
