100
This cell is alive at maturity with an unevenly thickened primary cell wall.
What is collenchyma.
100
This is the region of the root where cells are fully grown.
What is the Region of Maturation.
100
These structures on a stem are used to exchange gas.
What are lenticiles.
100
The arrangement of leaves when only one leaf grows per node.
What is alternate leaf arrangement.
100
An organ modification where the stem and leaves are reduced in size and become fleshy for storage (ie. onions.)
What is a bulb.
200
This protein is used to plug sieve tubes to prevent loss of sugar.
What is a p-protein/slime plug.
200
This primary meristem gives rise to the epidermis in the root.
What is protoderm.
200
This primary meristem gives rise the leaves.
What is leaf primordia.
200
When a single leaf is divided up into many leaflettes that attach along a main rachis.
What is pinnately compound.
200
A lateral growing stem that grows underground.
What is a rhizome.
300
This specialized xylem cell has tapered ends and bordered pits.
What is a trachied.
300
These two components are used to form vascular cambium.
What is the pericycle and residual procambium.
300
The pattern of growth stems show when they grow from axillary buds.
What is exogenous growth.
300
The margin type that is wavy.
What is a crenate margin.
300
A modification of a leaf where the lead becomes a reduced sharp appendage.
What is a spine.
400
This specialized epidermal cell is a thin projection that minimized water loss and hold secondary compounds.
What is a trichome.
400
This component of the endodermis is used to filter water on its way to the vascular cylinder.
What is the Casparian strip.
400
This wood forms during months of increased water and photosynthesis creating large xylem vessels.
What is early wood/spring wood
400
The paired leaflike appendages that sometimes subtend leaves.
What are stipules.
400
A modification of the stem, where the stem becomes flat and green and takes on the function of the leaves (beaver tail cactus.)
What is a cladode.
500
This is the empty cellular space within a dead sclerenchyma cell.
What is the lumen.
500
These roots rise out of marshes like snorkels to absorb oxygen and nutrients.
What are pneumatophores.
500
This wood is formed during months of decreased photosynthesis and water creating small xylem vessels.
What is late wood/summer wood.
500
The tightly packed upper layer of cells inside a eudicot leaf.
What is palisade mesophyll.
500
A modification of the petiole where the petiole becomes flat and green and takes on the function of the leaf.
What is a phyllode.
