Stelar System Of Plant: Definition And Types

Di: Amelia

This document provides information on the different types of stelar systems in plants. It defines the stele as the central vascular cylinder within a plant shoot. Plant cells are distinguished by their cell walls containing cellulose, chloroplasts that perform photosynthesis, and a large central vacuole that holds water and keeps the plant Studies of stelar organization have generated a widely ranging array of definitions that determine the way we classify steles and construct scenarios about the evolution of stelar

This paper reviews the concept and its foundations, and builds an argument for an updated view of steles and their In a general sense, stele types become progressively more complex in the fossil record and certain plant groups are characterized by particular types, so a knowledge of stele types is Types of steles Easu and Smith recognise two principal types of stelar organisation among the vascular plants. These are the Protostele and Siphonostele. Protostele
