| The seedlings are starting to grow! |
I was sick for a few days and wasn't able to update my posts. Here are some images from the seed starts that I had discussed in my last post.(See above) I have some nasturtium and tomato plants growing now!

| Nasturtium - They are an edible flower, they taste somewhat like a radish. They make a beautiful salad garnish and a great outdoor decoration! |
Mrs. Bell, all this plant testing going on, and we still do not have a conclusion on growing plants with out sunlight. And speaking of sunlight, i was thinking about UV rays from the sun and wondering, since the sun is just a ball of fire, does regular fireplaces, or bon fires put out UV rays??? p.s. this is eliajh
ReplyDeleteHi Elijah! Sorry for the delay! :) I have been very busy the past few days. Well I wasn't sure on the whole UV rays thing, so I looked it up. I found that essentially the sun is made up of constant chemical reactions and explosions; so it's a little more of a ball of fire... but enough on that. Most fires do not give off UV radiation the best that I understand. Some very hot fires (think blowtorch, welding apparatus, etc. do have some possibility of giving off UV rays). I still think some plants can survive a period of time without sunlight... that length of time probably depends on how much energy the plant can obtain from nutrients from its environment and were present in the endosperm (the nutrients in the seeds that provide energy for germination). The plant will continue to attempt to grow to reach sunlight until all of its energy resources are exhausted... the nitrogen from your fertilizer bag may have allowed for that energy to be used for a longer period of time. Also the plant may have put more energy into reaching the sunlight than producing chlorophyll and chloroplasts which is why parts of the plant we find underground are often white. This is just a hypothesis, but some more detail on why it kept growing w/o sunlight. Hope you're having a fantastic summer! :)
