Chapter 6 - Plant Body [Flower] Flashcards
Learn about the plant body. [Flower]
(identification) The reproductive organ of the flowering plants
FlOwEr
(identification) The outermost whorl and enclose the other floral parts in the bud.
Calyx
(T/F) The term “tepal” is used when the petals and sepals are attached to one another.
True
(T/F) Dicot plants have 4 or 5 sepals.
True
(T/F) Monocots have 3 or multiple of 4 petals.
False, Sepals
(identification) The second whorl inside the calyx.
Corolla
(identification) Collective name for the Calyx and Corolla
Perianth
(identification) Third whorl on the inside of the corolla.
Stamens
(identification) It supports the anther
Filament
(identification) produces pollen grains which contains the male reproductive cells
Anther
(identification) The fourth and innermost whorl of the flower, which consists the ovary.
Carpel
(identification) Hollow cavity which contains the ovule.
Ovary
(identification) The ovule contains the ___
Egg
(identification) Bears the stigma, receiving pollen during pollination.
Style
(enumeration) Difference between Complete and incomplete flowers
:Flowers with all sets of floral leaves
: Flowers lacking one or more of the 4 floral leaves
(enumeration) Difference between Perfect and Imperfect flower
: Unisexual flowers with either only one of the two (pistillate and staminate)
: Flowers with both of those
(enumeration) difference between Regular and Irregular flowers.
: Those with corolla that are made up of petals of similar shape, radiate from the center of the flower and are equidistant from each other.
: Tjose that have whorl with dissimilar flower parts (does not radiate from the center) or not equidistant from each other. (Only one line will divide the flower into 2 similar halves)
(identification) The ovary is situated above the calyx and there is no floral cup around it.
Hypogynous
(identification) Ovary situated within (and free from) a floral cup or hypanthium
Perigynous
(identification) Ovary is situated below the calyx
Epigynous
(identification) Flower-bearing branch or system of branches held by a peduncle.
Inflorences
(identification) One unbranched axis and the flowers with pedicels
Receme
(identification) One unbranched axis and the flowers sessile (without pedicel
Spike
(identification) Like a spike, but with flowers and inflorescence subtended by specialized bracts
Spikelet
(identification) Like a raceme, but the pedicels all elongating to give the flat topped appearance.
Corymb
(identification) All the pedicels arise from one point at the top of the peduncle.
Umbel
(identification) A central flower opens first and later flower are borne on branches below it.
Cyme
(identification) The main axis has branches which are in turn rebranched.
Panicle
(identification) Many small flowers borne on a common receptacle, looks like a single flower.
Head
(identification) One unbranched axis with fleshy stalk and the flowers usually reduced and unisexual.
Spathe/Spadix
(identification) The flower are borne in tight circle in each node
Verticil/ Whorl
(T/F) Stamens and Carpels are the ones responsible for sexual reproduction
True
(identification) Each consist by a stamen and a filament
Androecium
(T/F) The anther consists of pollen sacs that has 4 elongated and connected lobes
True
(T/F) Each pollen sac contains a mass of multiplying cells called Microsporocytes
Flase, dividing
(identification) consists of the stigma, style and the ovary.
Gymnoecium
(identification) Receptive suface on which pollen lands and germinates its pollen tube.
Stigma
(identification) Connects the stigma to the ovary.
Style
The transfer of pollen from anther to the female stigma though pollinators.
Pollenation
(identification) One sperm cell fuses with the egg while the other sperm fuses with the 2 polar bodies located in the center of the sac.
Double fertilization
(identification) The other name of Epicotyl
The Primordial Stem
