Why does the root appear before the shoot?

Answer 1

Before a fruit can be formed, the flowers must bloom so the male and female parts can develop and produce pollen and receptive ovules.It must bud after it is pollinated, then it can turn into a fruit.

Answer 2

Yes the roots appear before the the shoot because the plant must be able to transpire to push the leaf up.

Transpiration is the process whereas the plant sucks, like a straw, water from the soil to the leaf. The soil is the source of the water and the atmosphere is the sink. So the seed first puts out the root to create the 'source' of water and the cotyledons, because they are high in sugars and there are also special mechanisms, creates an osmotic draw that turns the transpiration 'pump' on which does 2 things.

1, it creates a complete straw that never goes dry because if your transpire tube goes dry, it really cant recover, especially in a tender baby.

2, it pushes 'turger pressure' into the leaf which then allows the cotyledon to push thru the soil and unfurl its leaf. the new leaf doesnt need nutrients as it has all it needs.

This is why a simple wet napkin will work to grow out the first few sets of leaves.

In essence, the same thing happens with all new leaves; first make a new root-->create turger thru transpiration-->shoot out a new leaf using the mechanism of transpiration to draw in the required item to make more leaf.

Now to get really deep... In reality, the leaf is developed while the seed is forming in the mama plant. But this cannot be said for the root as much. The root grows first, again using osmotic and turger pressures to expand downwards. So to truthfully answer your question, the shoot (leaf) is formed first, long before the root but the root appears first.

Answer 3

it starts out as a bud that's a baby flower
