Do all stems grow upward?
Gravity can be either “artificial gravity” or natural gravity. It is a general feature of all higher and many lower plants as well as other organisms. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards).
Why does the plant need to stay upright?
Turgor pressure is what allows plant cells to maintain upright growth. This puts pressure on the walls of the cell, leading to cell elongation and providing growing plant material with the rigidity to stay upright.
Why do things grow upwards?
Why do plants grow upward, against the force of gravity? Plants grow upwards in an attempt to reach a light source in order to begin photosynthesis.
Do seeds always grow up?
How do seeds figure out the effect of gravity and grow in the right direction? Short answer: Seeds can sense gravity and position themselves in accordance with it. This behavior is dictated by a physical phenomenon called gravitropism, wherein the growth of a plant is governed by the force of gravity acting on it.
