Plant Structure Lecture Flashcards

This set of vocabulary flashcards covers the anatomical structures of Eudicot and Monocot leaves, stems, and roots as presented in the Biological Sciences lecture notes from Clemson University.

Midvein

The central vein of a leaf, providing structural support and containing vascular tissues, found in both Eudicot and Monocot leaves.

Collenchyma

A type of support tissue found in the midvein of Eudicot and Monocot leaves, as well as in the Eudicot stem.

Palisade parenchyma

A layer of elongated cells located beneath the upper epidermis in Eudicot leaves, primary site for photosynthesis.

Spongy mesophyll

A layer of loosely arranged cells in the Eudicot leaf that allows for gas exchange through air spaces.

Stoma

A pore found in the epidermis of leaves (Eudicot and Monocot) that regulates gas exchange.

Trichome

A hair-like outgrowth from the epidermis of a Eudicot stem.

Vascular bundle

A strand of conducting vessels consisting of xylem and phloem, found in Eudicot and Monocot stems.

Xylem

The vascular tissue responsible for the conduction of water and minerals, present in stems and roots of Eudicots and Monocots.

Phloem

The vascular tissue responsible for the transport of sugars and other metabolic products.

Ground tissue

The background tissue of the plant that is not vascular or dermal, found in stems and the Monocot root.

Vascular cylinder

The central core of the root, containing the vascular tissues (xylem and phloem) in both Eudicots and Monocots.

Cortex

The region of ground tissue in a root located between the epidermis and the vascular cylinder.

Epidermis

The outermost layer of cells covering the leaves, stems, and roots of a plant.

Mesophyll cells

The photosynthetic tissue of a Monocot leaf, located between the upper and lower epidermis.
