Plant Tissue Systems and Simple Permanent Tissues

A set of vocabulary flashcards based on the lecture notes regarding plant tissue systems, epidermal structures, and simple permanent tissues like parenchyma.

Epidermal Tissue System

Composed of closely packed cells, that are mostly single-layered for providing protective covering to root, stem, and leaves.

Epidermis

A dermal tissue that forms the covering of young parts of root, stem, and leaves.

Stomata

Pores on the epidermis of leaves and young stems used for the exchange of gases as well as for transpiration.

Cuticle

A waxy coating secreted by the epidermis in leaves that prevents the plant from drying out.

Root hairs

Unicellular structures of the root epidermis responsible for the absorption of water and minerals from the soil.

Vascular Tissue System

Tissues made of a group of cells that form tubes for conducting water, minerals, and food across the plant body.

Ground Tissue System

The bulk of the plant responsible for providing mechanical support, synthesizing food, and acting as food storage tissues.

Simple Permanent Tissues

Tissues made up of one type of cells that are more or less similar in structure and function, including parenchyma, collenchyma, and sclerenchyma.

Parenchyma

Living cells that are thin-walled and spherical or oval, having a large vacuole and prominent nucleus; their main function is to synthesize and store food.

Intercellular spaces

The spaces found between cells in parenchyma tissue.

Mesophyll

Ground tissue in the internal structure of a leaf, also referred to as chlorenchyma.
