Stomata in epidermis of a leaf of a seedling of a dicotyledon plant narrowleaf marsh elder (Iva angustifolia) west from a water treatment plant, collected in Lick Creek ParkWeb page of Lick Creek Park by Dept. of Biology of TAMU. College Station, Texas

🎞️ #3464-14

The image presents a microscopic view of stomata on an epidermal leaf cell of a narrowleaf marsh elder (Iva angustifolia) seedling. The specimen was collected from Lick Creek Park, College Station, Texas, on January 29th, 2024.

**Key Features:**

* **Stomatal Structure:** Each stoma is encircled by two guard cells that are in contact at their ends with the epidermal cell walls.
* **Stoma Opening:** The stomata open through a pore between the two guard cells, allowing gas exchange and transpiration to occur.
* **Chloroplasts:** Chloroplasts can be seen within the guard cells, indicating photosynthesis.
* **Cell Walls:** The image shows the thin layer of cell walls that surround each stoma.

**Coloration:**

The image uses bright-field microscopy with a yellow filter, which enhances the contrast between the cell structures and background. The color scheme is predominantly white and yellow, providing clear visibility of the stomatal structure.

**Conclusion:**

This microscopic view provides valuable information about the anatomy of narrowleaf marsh elder seedlings. It highlights the importance of stomata in plant physiology and demonstrates how these structures contribute to gas exchange and transpiration. – AI vision

Las estomas en la epidermis de una hoja de una plántula dicotiledónea del sauce americano (Iva angustifolia) al oeste de una planta de tratamiento de agua, recogida en el Parque Lick Creek. College Station, Texas, 29 de enero de 2024. La imagen presenta una vista microscópica de las estomas en una célula epidérmica de una plántula del sauce americano (Iva angustifolia). El espécimen fue recogido en Lick Creek Park, College Station, Texas, el 29 de enero de 2024. **Características clave:** * **Estructura estomática:** cada estoma está rodeado por dos células paliçadas que están en contacto en sus extremos con las paredes celulares epidérmicas. * **Apertura de los estomas:** los estomas se abren a través de un poro entre las dos células paliçadas, lo que permite que ocurran el intercambio gaseoso y la transpiración. * **Cloroplastos:** pueden observarse cloroplastos dentro de las células paliçadas, lo que indica fotosíntesis. * **Paredes celulares:** la imagen muestra la delgada capa de paredes celulares que rodean cada estoma. **Coloración:** la imagen utiliza microscopía de campo brillante con un filtro amarillo, lo que mejora el contraste entre las estructuras celulares y el fondo. El esquema de color es predominantemente blanco y amarillo, proporcionando una visibilidad clara de la estructura estomática. **Conclusión:** esta vista microscópica proporciona información valiosa sobre la anatomía de las plántulas del sauce americano. Destaca la importancia de los estomas en la fisiología vegetal y demuestra cómo estas estructuras contribuyen al intercambio gaseoso y a la transpiración. – Spanish translation
