Flashcards in Plant Structure, Growth & Development Deck (44):
This is a multicellular organ that anchors vascular plant in the soil and absorbs water and minerals below ground.
This organ depends on water and minerals from the roots.
This the main vertical root that gives rise to lateral roots.
These roots occur above ground and have been modified to support/anchor, store water and nutrients and absorb oxygen from the air.
These roots support tall, top heavy plants.
These roots support tall trunks, especially in the tropics.
Aid in gas exchange.
These roots germinate in branches of tall trees and grown down.
This is the main photosynthetic multicellular organ.
This type of leaf is a single undecided blade.
This type of leaf is comprised of multiple leaflets.
On this type of leaf, each leaflet is divided into a smaller leaflet.
Doubly compound leaf
These are vine-like structures that help stabilize the plant.
These modified leaves aid in protection from predators.
These type of leaves store water.
These leaves produce plantlets that fall off and take root.
These modified leaves resemble petals.
This is the outer covering of the plant.
This is responsible for storage, photosynthesis and support.
Responsible for long distance transport through the plant.
This is the single outermost layer of tightly packed cells functioning in protection, defense, uptake and gas exchange.
Waxy hosting secreted by epidermal cells to prevent water loss.
Hair-like outgrowths of the shoot epidermis functioning in predator defense, reflecting excess and water loss reduction.
These cells regulate the opening and closing of the stomata and function in carbon dioxide and water exchange.
External to vascular tissue.
Internal to vascular tissue.
Generalized plant cell and the least specialized. Major locations include; cortex, pith, stems, roots internal layer of leaves (mesophyll).
These cells are grouped in strands, have thick, uneven walls and provide strength and flexibility for growth.
These cells have thick rigid walls are strengthened with lignin and act as a skeleton for strength and support.
This type of sclerenchyma cell us short, irregularly shaped and is what provides hardness to seeds and nutshells.
This type of sclerenchyma cell is long, slender and tapered and arranged in threads.
This joins the leaf to the stem at the node.
This is the space between the petiole and the stem.
This is plant growth throughout the lifetime.
These are tissues that allow growth.
APICAL MERISTEMS are located in tips and roots, shoots and buds and are responsible for _________.
Primary Growth (length)
LATERAL MERISTEMS are responsible for ____________.
Secondary Growth (thickness)
This adds layers of secondary xylem and phloem.
This adds layers of secondary dermal tissue called cork.
This is a root system with a mat of thin roots that spread.
Fibrous Root System
This is the stalk that attaches the leaves to the stem.
This is the broad surface of a leaf.
This is the point of attachment on the stem.
