Horticulture Lab Exam 2

Epidermis

The outermost protective waterproof layer on a stem

Cortex

Ground tissues that fill the Sims storing food and providing structural support

Vascular bundles(xylem and phloem)

Xylem transports water upward, phloem moves sugars

Nodes

Points where leaf attaches

Internode

Spaces between the nodes

Buds

Terminal in lateral that provide sites for new growth

rhizome

Lateral jointed, stems that originate from the crown, travel below ground and develop new shoots and roots along the way

Stolon

Lateral jointed, stems that originate from the crown, travel above ground and develop new shoots and roots along the way

bulb

Highly compressed underground stem which numerous storage leaves are attached

Corm

Short, vertical, swollen underground plant stem that serves as a storage organ

Tuber

Enlarged fleshy terminal portion of underground stem

Epidermis

Part of the leaf that is upper and lower layers within the cuticle to prevent water loss

Stromata

Small pores on the leaf surface that manage gas exchange

Mesophyll

Ground tissue on the leaf filled with chloroplast for photosynthesis

Vascular bundle

Xylem and phloem on the leaf used to transport water and photosynthesis

Midrib

Central vein of the leaf

Parenchyma

The all-purpose cells that are thin walled alive and do heavy lifting like storing food and performing photosynthesis

Collenchyma

The flexible support cells that have thicker corners and provide stretchy strength to grow stems and leaves
