Chapter 35.1 Flashcards
Tissue
A tissue is a group of cells consisting of one or more cell types that together perform a specialized function
Organ
An organ consists of several types of tissues that together carry out particular functions
Root System
The roots of a plant
Shoot System
consists of leaves, stems, flowers, and fruits
Root
Anchoring the plant
Absorbing minerals and water
Storing carbohydrates
Taproot
A taproot, the main vertical root
Lateral Roots
Lateral roots, or branch roots, that arise from the taproot
Root Hairs
absorption of water and minerals occurs near the root hairs
Stem
A stem is an organ consisting of nodes and internodes
Nodes
A point of attachment of a leaf or a twig on the stem in seed plants
Internodes
the stem segments between nodes
Axillary Bud
An axillary bud is a structure that has the potential to form a lateral shoot, or branch
Apical Bud
An apical bud, or terminal bud, is located near the shoot tip and causes elongation of a young shoot
Apical Dominance
Apical dominance helps to maintain dormancy in most axillary buds
Leaf
The leaf is the main photosynthetic organ of most vascular plants
Blade
The leaf of a plant
Petiole
Leaves generally consist of a flattened blade and a stalk called the petiole
Veins
Most monocots have parallel veins
Most eudicots have branching veins
Dermal Tissue System
In nonwoody plants, the dermal tissue system consists of the epidermis
Cuticle
A waxy coating called the cuticle helps prevent water loss from the epidermis
Periderm
In woody plants, protective tissues called periderm replace the epidermis in older regions of stems and roots
Vascular Tissue System
The vascular tissue system carries out long-distance transport of materials between roots and shoots
Xylem
Xylem conveys water and dissolved minerals upward from roots into the shoots
Phloem
Phloem transports organic nutrients from where they are made to where they are needed
