Conclusion
Aphototropism is a term used to describe the response of plants to light. It is a phenomenon whereby plants grow in a direction away from light. This response is generally seen in plants that grow in low light conditions or in environments where light is not readily available. In this article, we will explore the definition, origin, meaning, associations, synonyms, antonyms, and examples of aphototropism.
Definitions
Aphototropism is defined as the growth of a plant away from a source of light. This response is caused by the presence of certain hormones in the plant that are activated by the absence of light. Aphototropism is also known as negative phototropism.
Origin
The word aphototropism is derived from the Greek words “a-” meaning “not,” “photo-” meaning “light,” and “tropism” meaning “turning.” The term was first used in the early 20th century to describe the response of plants to light.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, aphototropism is defined as “the growth or movement of a plant away from a source of light.” The Oxford English dictionary defines it as “the tendency of a plant to grow or move away from a source of light.”.
Associations
Aphototropism is associated with plants that grow in low light conditions, such as those found in the understory of forests. It is also seen in plants that grow in environments where light is not readily available, such as underwater plants.
Synonyms
The synonyms of aphototropism include negative phototropism, geotropism, and gravitropism.
Antonyms
The antonyms of aphototropism include positive phototropism, which is the growth of a plant towards a source of light.
The same root words
The same root words as aphototropism include phototropism, which is the growth of a plant towards a source of light, and tropism, which is the turning or bending of an organism in response to an external stimulus.
Example Sentences
- The aphototropism of the plant allowed it to survive in the low light conditions of the forest floor.
- The underwater plants showed a strong aphototropism, growing away from the limited light available.
- The aphototropism of the seedlings was a response to the lack of light in the laboratory.
Aphototropism is a natural response of plants to light that allows them to survive in low light conditions. It is a negative phototropism that is caused by the absence of light and is associated with plants that grow in environments where light is not readily available. Understanding aphototropism is important for botanists and gardeners alike, as it can help them to better understand the growth patterns of plants in different environments.
