Botany Plant Adaptation & Identification Flashcards
Two plant species which exhibit drought deciduousness are:
brittle bush
bursage
Thick waxy evergreen leaves, leaves orient vertically.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Jojoba
Deep roots and shallow roots, small leaves, chemicals in roots to inhibit seed germination, waxy cuticle.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Creosote
Fill in the blanks to complete the sentence using the following:
(pistil, stigma, style, ovary, stamen, anther, filament, chlorophyll, light, ovules, seeds and sperm)
The female part of a flower is the _____, composed of ______, ______ and ______.
The female part of a flower is the pistil, composed of stigma***, ***style*** and ***ovary.
How do botanists identify plants unknown to them?
Dichotomous key
(based on flower and fruit)
Desert plants survive the long rainless periods with what 3 main adaptive strategies?
Drought avoidance,
Drought tolerance
Succulence
Gray leaves reduce water loss by reducing leaf temperature (by reflection of light); new leaves get smaller and whiter as soil dries; loses leaves during very dry times, tolerates severe dehydration without dying; deeper roots exploit soil that stays wet sevral weeks after a soaking rain.

Brittlebush
An example of a drought deciduous plant is:
ocotillo
Fill in the blanks to complete the sentence using the following:
(pistil, stigma, style, ovary, stamen, anther, filament, chlorophyll, light, ovules, seeds and sperm)
The male part of a flower is the _____, composed of the ______ and the _______.
The male part of a flower is the stamen***, composed of the ***anther*** and the ***filament.
Drought deciduous, small leaves, photosynthesize in stems and trunk, deep roots.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Palo verde
Fill in the blanks to complete the sentence using the following:
(pistil, stigma, style, ovary, stamen, anther, filament, chlorophyll, light, ovules, seeds and sperm)
_______ (the green pigment in plants) captures _____ energy and converts it into a stable form usable for biological process.
Chlorophyll*** (the green pigment in plants) captures ***light energy and converts it into a stable form usable for biological process.
Drought deciduous, can also photosynthesize through stems.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Ocotillo
Which is the correct format to identify a species of animal or plant?
Example:
Encelia farinosa and Encelia farinosa
(underlined or italic, with genus first letter upper case and specific ephithet first letter lower case)
Succulent that stores water inside its tissues; extensive and shallow root system for absorbing large amounts of water from light rains; CAM metabolism uses water more efficiently, CAM idling mechanism enable rapid recovery following rain, waxy cuticle renders plant nearly waterproof when stomata are closed.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Barrel cactus
Plant taxonomy is based almost entirely on reproductive parts.
True or False
True
Place the seven classifications in the correct order.
Class
Family
Genus
Kingdom
Phylum-subphylum
Order
Genus + Specific Ephithet = species
Annual that spends unfavorable season as dormant seeds; seeds germinate only after sufficient rain has fallen to assure survival; germinate only in the fall; not all will germinate after a given rain.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Mexican gold poppy
Fill in the blanks to complete the sentence using the following:
(pistil, stigma, style, ovary, stamen, anther, filament, chlorophyll, light, ovules, seeds and sperm)
The ovary contains ______, which develop into ______ when fertilized by the _____ in pollen.
The ovary contains ovules***, which develop into ***seeds*** when fertilized by the ***sperm in pollen.
Nearly half of the flora of the Sonoran Desert is comprised of annual species.
True or False
True
Small leaves (leaflets), deep tap root.
Mexican gold poppy, Barrel cactus, Brittlebush, Creosote, Jojoba, Ocotillo, Agave, Palo verde, Mesquite
Mesquite
Spring annuals in the Sonoran Desert:
avoid drought by escaping in seed form
Petals are frequently the visual advertising banner that atracts pollinators.
True or False
True
The process by which plants capture light energy and convert it to stored chemical energy describes:
photosynthesis
