in a plant the lateral meristem that produces secondary xylem and phloem
The innermost layer of the cortex in plant roots; a cylinder one cell thick that forms the boundary between the cortex and the vascular cylinder.
The study of tissues
The parts of a plant (such as stems, roots, and leaves) that are not involved in reproduction
Areas of rapidly dividing cells
Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
Growth region of a plant that provides secondary growth, increase in girth
meristem near nodes at the intervals of the plant allowing a quick growth
Type of structural tissue found in roots, stems, leaves, and fruits that makes and stores food
a tissue bordering the veins of leaves and making up the “strings” in celery
dead cells with thick walls that have lignin and provide strength and support
slender cells that occur in strands and are commonly found in roots, stems, leaves and fruits.
far stubbier than fibers and often branched, these are another typical sclerenchyma cell that strengthens hard seed coats such as peach pits, and make pear flesh gritty
A strand of vascular tissues (both xylem and phloem) in a plant stem.
A single thick root that grown straight down. It can reach water that is deep in the ground. Store food for the plant.
part of a root system in which roots branch to such an extent that no single root grows larger than the rest
root arising above the ground from stems or leaves
parasitic roots that parasitize a host plant
a structure that covers the tip of a root, protecting the root from injury
waterproof strip that surrounds plant endodermal cells and is involved in the one-way passage of materials into the vascular cylinder in plant roots.
The outermost layer of the vascular cylinder of a root, where lateral roots originate.
ground tissue that is internal to the vascular tissue
roots growing from the primary root
The area of a plant’s stem from which the leaves grow
bud at tip of a stem responsible for terminal growth, contains the tip of the shoot
modified leaves protecting the terminal bud
buds with embrionic shoots that can give rise to new branches or flowers and are located between the petiole and the stem
structures on the twig allowing gas exchange
modified stem that is growing beneath the surface in different directions
Swollen, fleshy, underground stem. Stores food. Ex. Irish potatop
modified stem found in honey locust
only one blade
many blades for one leaf
pinnately compound leaf
a compound leaf with leaflets attached like vanes of a feather to an elongated rachis
palmately compound leaf
leaflets from a single point
arrangement of leaves on a stem
opposite leaf attachment
two leaves per node
alternate leaf attachment
one leaf per node
whorled leaf attachment
three or more leaves per node
ground tissue of a leaf
in plants, the layer of vertically elongated cells that contains chloroplasts, that is located beneath the upper epidermis of leaves, and that participates in photosynthesis
inside a leaf, the tissue that is made up of loosely arranged parenchyma cells that contain chloroplasts and are surrounded by air spaces that promote the diffusion of oxygen, carbon dioxide, and water throughout the leaf
The two cells that flank the stomatal pore and regulate the opening and closing of the pore.
Name the layers of a monocot root
root branch, pericycle
what is this structure?
where does it originate from?
where does it originate from?
All tissues external to the vascular cambium, consisting mainly of the secondary phloem and layers of periderm (cork, cork cambium in case of woody plants)
eudicot leaf epidermis
monocot leaf epidermis
