- The stem of a woody plant is reinforced with
- vascular rays and collencyma
- Vascular tissues in plants arise from the
-
meristem cells, procambium, and cambium
- Xylem vessels are found in
-
angiosperms, gnetophytes
-
The age (in years) of a woody plant can be determined by counting
-
vascular rings
-
The tall column shaped cells in leaves just below the upper epidermis is called
-
palisade parenchyma
- The vascular tissues in the veins of leaves is surrounded by
-
bundled sheath cells
- The movement of air into and out of leaves is controlled by
-
stomata, guard cells, turgor pressur
- The purpose of leaf hairs is to
-
limit loss of water by evaporation
- The Casparian strip is found in the
- endodermis
-
The movement of water from root to leaf is accomplished with the help of
-
osmotic push, capillary action, transpiration "pull"
- The acquisition of soluble nitrates by plants is helped by the
- rhizobia
-
The acquisition of soluble phosphates by plants is helped by the activities of
- mycorhizza
-
The elongation of plants cells during primary growth is controlled by
- sunlight, auxins, and the acid grow effect
- cytokinins
-
accelerate cell division
- The rate at which fruit ripens is effected by
- ethylene
- The plant hormone that induces bud dormancy is
- abscisic acid
- Wound reactions occur in response to the release of
- oligosaccharins
- The uneven growth of some plants in response to touch is
- thigmotropism
