Noun

Pronunciation

/ˈeɪpɪkəl ˈmɛrɪstɛm/

Definitions

• A region of actively dividing cells at the tip of the plant shoot or root that is responsible for the growth in length of the plant.
• In botany, the apical meristem is where new cells are produced to extend the plant's roots or stems and is crucial for the plant's vertical growth.

Usage Examples

• The apical meristem of the plant grew rapidly, pushing the shoot upwards.
• Damage to the apical meristem can stunt the growth of the plant.

Etymology

The term "apical meristem" is derived from "apical," meaning "of the apex" (from Latin apex, meaning "tip" or "summit"), and "meristem," from Greek "meristos," meaning "divisible," referring to the plant cells' ability to divide and produce new growth.

Synonyms

• Growing tip
• Meristematic region

Antonyms

• Basal meristem
• Non-meristematic region

Historical Usage

The concept of apical meristems was first described in the early 19th century. The discovery of the growth potential in these regions significantly advanced plant biology and botany, helping scientists understand how plants grow in length and how various factors can affect this growth process.

Cultural Nuances

In some cultures, plants are seen as symbols of life and growth, with the apical meristem symbolizing vitality, renewal, and the drive for expansion. In agricultural societies, understanding the role of the apical meristem has been crucial in improving crop yields through effective pruning and growth management.

More Information

The apical meristem is one of the key factors responsible for the vertical growth of plants. By continuously producing new cells, it allows plants to extend their shoots and roots, providing them with the ability to absorb nutrients and grow towards sunlight. Apical meristems are vital not only for normal plant growth but also for responses to environmental stressors such as drought or physical damage. The apical meristem's function is essential for plant survival, and research into its mechanisms continues to play a significant role in agricultural and botanical studies.
