Overview
Tissue is a group of similar cells that perform a specific function. Multicellular plants and animals are made of many kinds of tissues, and each tissue has a special job. Plant tissues are mainly of two types: meristematic tissue and permanent tissue. Animal tissues are classified into epithelial,
Key Concepts
A tissue is a group
A tissue is a group of cells that are similar in structure and perform a specific function.
Meristematic tissue is made of actively
Meristematic tissue is made of actively dividing cells. Its only function is to produce more cells for plant growth. These cells are small, thin-walle
Permanent tissue is a non
Permanent tissue is a non-dividing tissue that forms the bulk of the plant body. It is formed from meristematic cells after differentiation and is div
Parenchyma is a simple permanent supporting
Parenchyma is a simple permanent supporting tissue made of large thin-walled living cells with intercellular spaces. It stores food, and some cells co
Collenchyma is a simple permanent supporting
Collenchyma is a simple permanent supporting tissue made of living, elongated cells that are thick at the corners or edges. It is found in leaf stalks
Learning Objectives
- Define tissue and explain why tissues are important in living organisms.
- Classify plant tissues into meristematic and permanent tissues.
- Describe the characteristics, locations, and functions of parenchyma, collenchyma, sclerenchyma, xylem, and phloem.
- Classify animal tissues into epithelial, connective, muscular, and nervous tissues.
- Identify the basic structure, location, and function of major animal tissues such as bone, cartilage, blood, tendon, ligament, striated muscle, unstriated muscle, cardiac muscle, and neuron.
