What can we learn ?'
- That plants require a specific temperature range for growth as the video shows Charlie
being 'depressed' and wilting due to the seasonal change to winter.During winter in
either hemisphere, the lower altitude of the Sun in winter causes the sunlight to hit
that hemisphere at an oblique angle.Light have to travel a longer distance over the atmosphere.Thus,plants receive less sunlight in winter. - Seeds don't make their own food! So where do they get it? At first the seed gets its food from the cotyledons which are the store house of many nutrients from what I understand. It uses these to grow the first leaves and from there on it makes its own food by photosynthesizing.
OR - A seedling gets food from stored areas of adults plants like roots, stems and leaves. This "food packet" is called an endosperm in flowering plants. However some plants, such as some orchid seeds are so small that they include no endosperm This is different in gymnosperms, but the overall principle is the same, the parent plant provides the seed with nutrition so yay.
