Animal and Plant Tissue: A Comprehensive Guide

Variations in Animal and Plant Tissue

Cells, the fundamental units of life, group together to form tissues in both animals and plants. These tissues possess distinct structures, functions, and origins. Animal and plant tissues differ significantly, as discussed below.

Plant Tissue Systems

In plant anatomy, tissues are broadly categorized into three systems:

• Epidermis: Cells forming the outer surface of leaves and other plant structures.
• Ground Tissue: Cells that make up the majority of the plant's内部结构.
li>Vascular Tissue: Cells responsible for transporting water and nutrients.

Main Differences: Plant vs. Animal Tissue

Despite their similarities, animal and plant tissues exhibit several key differences. Animal tissues lack cell walls, plastids, and vacuoles, which are characteristic of plant tissues. Additionally, animal tissues have specialized intercellular matrices, while plant tissues are held together by pectin and other cell wall components.
