We don’t usually think of plants as parents,
but when they make a seed, they put in a lot of
energy and nutrients. This gives the new plant a
good start in life. The new sprout may be buried
deep underground, so it needs a good food supply
until it can start collecting light and carbon
dioxide from its leaves and nutrients from its
roots. People have bred plants like rye for
hundreds of years to get seeds that are packed
with food. We usually collect the seeds and grind
them for flour, so we want them to be full of
energy and nutrients.
So those young plants are doing fine now, even
in the dark because they are using the stored
food. They are a pale green and tall because
they are putting most of their energy into growing
up instead of making green chlorophyll.
Why? Because they aren’t getting any
light. This usually means that a seed is too
far underground and its only chance for survival
is to grow as fast as it can so that it can get
some light before the food in the seed runs out.
Which plant do you think will last longer in
the dark, the sweet potato or the rye grass?
Thanks for asking,
Keep experimenting and wondering!
