It needs soil, water, sunlight and nutrients.
The embryo is the baby plant. It has an embryo root to push its way eventually out of the seed coat, and embryo stem, and embryo leaves which will later start food production.
It must push its plumule through the soil to emerge during seed germination.

Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
Friction of the ground against the player's shoes.
When hail falls to the ground, it is because of the force of FRICTION!! :)
i dont know
When you stand still . . . The sole of your shoe exerts a downward force equal to your weight against the ground. The ground exerts an upward force equal to your weight against the sole of your shoe. The net force where the sole of your shoe meets the ground is zero, which is the reason that your shoe doesn't accelerate vertically.

...he exerts against the ground
the up thrust force on us is the ground stopping us from flying straight to the core.It acts against gravity.
The answer is reaction. A simple example is you standing on the ground. You are not moving or accelerating (in our reference frame). You are pushing down against the ground with a force (the action) equal to your weight. The ground pushes back up (opposite direction) with an equal force (the reaction force).
