Geotropism

Description: Geotropism is the response of a living organism to gravity, causing either upward or downward growth in response to the gravitational pull. It is a fundamental concept in biology and botany that influences the growth and development of roots and stems.

Parts of Speech: Noun

Senses:

1. Positive geotropism: The response of a plant or organism to grow or move towards the direction of gravity. This is commonly observed when roots grow downwards into the ground.
2. Negative geotropism: The response of a plant or organism to grow or move against the direction of gravity. This can be observed when plants exhibit upward growth towards light.

Usages:

1. The geotropism of roots allows plants to anchor themselves firmly in the ground and absorb nutrients effectively.
2. The negative geotropism exhibited by shoots helps plants in their search for sunlight, enabling them to photosynthesize efficiently.

Sample Sentences:

1. The geotropism of the seedling's roots caused them to grow deep into the soil.
2. The plant displayed negative geotropism, as its stems reached towards the window where the sunlight poured in.
