Chapter 22, Problem 12A

Summary Introduction

To construct: a graphic organizer that lists each of the four different type of tissue, the function of each and the types of cells it contains.

Introduction:

Tissue is a group of similar or different cells joined together to perform one or more specific functions. In plants tissue is categorized broadly into four different types of tissue. They are meristem tissue, ground tissue, dermal tissue and vascular tissue.

Explanation of Solution

Type of tissue	function	Type of cells
Meristem tissue	Meristem tissue helps in primary growth of plants.	Made up of rapidly dividing cells.
Ground tissue	Provide support and stores the product of photosynthesis.	Made up of three plant cells parenchyma, collenchyma and sclerenchyma.
Dermal tissue	Provides cover and protection to the plant. Secretes waxy substance called cuticle which helps in protection of plant.	Made up of epidermal cells
Vascular tissue	Helps in transportation of water, food and other dissolved substances in plants.	Xylem- xylem tracheids, xylem vessel, xylem sclerenchyma, xylem parenchyma. Phloem- sieve tube, companion cell, phloem fibre, phloem parenchyma.
