Elongation of the meristematic tissue
Geotropism is a plant growth or movement in response to gravity. Upward growth of the plant's parts against gravity is called negative geotropism, whilst downward growth of roots is called positive geotropism.
The shoots of plants respond to gravity through a process called gravitropism, where they grow in the direction of gravity. This response helps the shoots to grow upward and the roots downward, optimizing their position for optimal growth and nutrient absorption. Specialized cells called statocytes sense gravity and trigger hormonal changes that mediate this growth response.
The upward force is called lift, while the downward force is called weight or gravity.
An upward slant indicates a positive trend or growth in something, such as sales or performance. A downward slant indicates a negative trend or decline in something, such as productivity or stock prices.
Corn plants exhibit a phenomenon called gravitropism, where their roots grow downward in response to gravity while their shoots grow upward. If the corn plants were placed in a dark environment and still demonstrated this growth direction, it would indicate a response to gravity rather than light. Additionally, if the plants were rotated, but their roots continued to grow downward and shoots upward, this further supports the conclusion that gravity is the primary factor influencing their growth orientation. Other factors like water and seed orientation would not consistently produce the same directional responses.
An upward slant is known as an incline or ascent, while a downward slant is called a decline or descent. These terms are often used to describe the direction or angle of a slope or surface.

Both geotropism and phototropism involve plant growth responses to external stimuli. Geotropism is a plant's growth response to gravity, which helps roots grow downward and stems grow upward. Phototropism is a plant's growth response to light, guiding plants towards a light source for photosynthesis. Both tropisms aid plants in optimizing their growth and development.
Upward.
Gravitropism is a plant's growth response to gravity. It involves the bending or growth of a plant in response to a gravitational stimulus, usually resulting in roots growing downward and shoots growing upward. This helps plants anchor themselves in the soil and optimize their exposure to sunlight for photosynthesis.
