- Group of cells that perform or help to perform a common function to have a common origin in plants

A collection of similar cells performing an organized function for the plant

Each ________________ is specialized for a unique purpose, and can be combined with other tissues to create organs such as leaves, flowers, stems, and roots

Classification of plant tissues Meristematic - length - found tip of the root

Classification of plant tissues Meristematic - diameter/width - along the side, not present in monocot

Classification of plant tissues Meristematic - rapid growth of young stem

Classification of plant tissues Permanent - Protection - gas control - water absorption

Classification of plant tissues Permanent - Different function based on cell type

Classification of plant tissues Permanent - Transport water and nutrients ( mineral, sugar etc.)

Types of dermal tissues - protection -absorbs water

Types of dermal tissues - gas exchange

Types of dermal tissues - reduce transpiration

Types of ground tissues - aids in photosynthesis - storage in the roots

Types of ground tissues - shoot support (active)

Types of ground tissues - shoot support (ceased) - made up of dead cells

Simple permanent tissues - this is an outermost layer of cells found in all young plant organs

Simple permanent tissues - these are the most abundant of all cell types found in almost all major parts of higher plants

Simple permanent tissues - Elongated cells are irregularly thick cell walls that provide support and structure

Simple permanent tissues - characterized by cells that are thick-walled cells

Simple permanent tissues - serves as the outermost covering of old stems and old roots of woody dicot plants

Simple permanent tissues - tissues that are concerned with the secretion of gums, presence, violative oils, nectar, latex and other substances in plants

Types of vascular tissues - transport water and nutrients - upward

Types of vascular tissues - transport organic compounds - downward

Complex permanent tissues 1. Xylem - similar and appearance to ordinary sclerenchyma fibers

Complex permanent tissues 1. Xylem - smaller in size than ordinary parenchyma cells

Complex permanent tissues 1. Xylem - long tubes made up of individual cells that are open at each other and and are joined and to end to form the tubes

Complex permanent tissues 1. Xylem - more or less elongated cells with oblique and tapering end walls - they are angular in cross-section and are dead at maturity

Tracheids and vessel elements make up the so-called tracheary elements of the xylem - helical or ____ appearance in the thickening

Tracheids and vessel elements make up the so-called tracheary elements of the xylem - thickening appear ladder-like

Tracheids and vessel elements make up the so-called tracheary elements of the xylem - With rounded depression or poor-like structures called pits

Tracheids and vessel elements make up the so-called tracheary elements of the xylem - thickenings appear web or net-like

Tracheids and vessel elements make up the so-called tracheary elements of the xylem - cell wall thickenings in ring-like forms

Complex permanent tissues 2. Phloem - small nucleated parenchymatous cells that are usually associated with some sieve tubes

Complex permanent tissues 2. Phloem - look like ordinary sclerenchyma fibers

Complex permanent tissues 2. Phloem - looks like ordinary parenchyma cells

Complex permanent tissues 2. Phloem - elongated cells joined joined end to end, forming sieve tubes

- loss of water from plants in the form of water vapor
