WSU BIO 106 Final Exam 1 Questions
and All Correct Answers.
The three basic plant organs, ________, are organized into_____________. - Answer Leaves,
Stems, Roots; A shoot system and a root system
Nodes - Answer The point at which leaves are attached
Internodes - Answer The stem segments between nodes
Root - Answer -An organ that anchors the plant into the ground
-Absorbs minerals and water from the tip
-Stores organic nutrients
-Root hairs increase surface area and absorb most of the water and minerals
Axillary Bud - Answer A structure that has potential to form a lateral shoot (branch)
Terminal Bud - Answer Located near the shoot tip and causes elongation of a young shoot
Leaves - Answer -Main photosynthetic organ for most vascular plants
-Consists of a flattened blade and petiole
Petiole - Answer A stalk which joins the leaf to a node of the stem
Simple Leaf - Answer A simple leaf in a single, undivided blade
Compound leaf - Answer Blade consists of multiple leaflets
Doubly Compounded Leaf - Answer Each leaflet is divided into smaller leaflets
Each plant organ has ______, ______, and ________ tissues - Answer Dermal, vascular, and
, Periderm - Answer In woody plants, this replaces epidermis in older tissue
Dermal Tissue - Answer Outer protective covering
Vascular tissue - Answer Carries out long-distance transport of materials between roots and
shoots
Xylem - Answer Transports water and solutes from the roots to the leaves
Phloem - Answer Transports food from the leaves to the rest of the plant
Ground Tissue - Answer Includes various cells specialized for functions such as storage,
photosynthesis and support
Parenchyma - Answer Generally lack secondary walls, perform metabolism and contain
plastids
Collenchyma - Answer Flexible support cells without secondary wall
Sclerenchyma - Answer Thick secondary walls primarily for support
Apical meristems - Answer Located at the tips of roots and in the buds of shoots
Lateral meristems - Answer Add thickness to woody plants through secondary growth
Shoot Apical Meristem - Answer -Dome-shaped at the tip of terminal and axillary buds
-Gives rise to internodes and leaf-bearing nodes
Epidermal barrier in leaves - Answer Is interrupted by stomata
Ground tissue in leaves - Answer Sandwiched between upper and lower epidermis
