TRUE LEAF is any leaf produced after the cotyledons.
TRANSPIRATION is the process in which plants lose water through pores in their
leaves (these openings are called stomata). As water is lost from the plant, the plant takes
up more water (and minerals) through its roots. The rate of transpiration varies as the
conditions of the plant change and is controlled by the opening and closing the stomata.
TUBER is a modified root that stores nutrients. Potatoes are tubers.
VARIETY is an identifiable strain within a species, usually referring to a strain which
arises in nature as opposed to a cultivar which is specifically bred for particular
properties; sometimes used synonymously with cultivar.
VEGETABLE is a plant whose stem, leaves, tubers, roots, bulbs,
or flower is a food source for people. Some examples of vegetables
include carrots, eggplant, potatoes, spinach, broccoli, onion, and
asparagus. Refer to Figure 25.
Figure 25.
VEGETATION is all of the plant life found in an area.
VEGETATIVE PROPAGATION is a method of reproducing asexually; the offspring
have the same genetic makeup as the parent.
VEGETATIVE STATE is the stage in a flowering plant's life cycle before the
appearance of its fruiting structures.
VEIN is a vascular structure (xylem and phloem cells surrounded by the bundle sheath)
in a leaf that provides support for the leaf and transports both water and food. The veins
on monocots are almost parallel to the margins of the leaf. The veins of dicots radiate
from a central midrib. Refer to Figure 3.
VEINLET is a small vein. Veinlets are located toward the
margins of the leaf. Refer to Figure 16.
VENATION is the arrangement of veins in a leaf. Some
different venation patterns include pinnate, palmate and
parallel. Refer to Figure 12.
VINE is a plant that needs support as it grows. Some vines
grow by twining around other objects for support (e.g.,
morning glory), some use tendrils (modified shoots) to
attach to objects (e.g., peas and vetch), and others send out
aerial roots, often with suckers (e.g., poison ivy). Refer to
Figure 26.
