Stomata and Hydathodes are specialized pores present in the aerial parts of plants associated with the release of water from the plant body to the surrounding environment. Stomata: They are specialized pores present on the surface aerial plant parts especially on the lower epidermis of leaf, which facilitate Gaseous exchange […]
Phloem is a permanent vascular tissue system associated with the conduction of food materials in plants. It is a complex tissue composed of more than one type of cells namely sieve elements, companion cells, phloem fibres and phloem parenchyma. Among these cells, the sieve elements are the most specialized cells […]
Parenchyma vs Collenchyma Parenchyma and Collenchyma are the Simple tissue System in Plants. The present post describes the similarities and differences between Parenchyma and Collenchyma Similarities between Parenchyma and Collenchyma Ø Both parenchyma and collenchyma are simple permanent tissues in the plants. Ø Both are differentiated cells. Ø Both are […]
Protophloem vs Metaphloem Vascular bundles (fascicles) are the component of the stelar system in higher plants and their main function is the conduction of water, minerals and food materials. Typically, a vascular bundle composed of xylem and phloem arranged together as bundles. In a young stem, both in dicots and […]
Vessels and tracheids are the components of xylem, the water and minerals conducting tissue in plants. Vessels and tracheids are jointly known as the tracheary elements of the xylem. Even though, both vessels and tracheids show functional similarities, they do possess some striking differences. The present post describes the similarities […]
