Angiosperm Reproduction Flashcards
This is a vascular flowering plant that contains seeds that are enclosed in a chamber (fruit).
Angiosperm
This is a vascular non-flowering plant that contains naked seeds that are not enclosed in chambers.
Gymnosperm
This is an angiosperm structure that is specialized for sexual reproduction.
Flower
This is the base of the flower which serves as protection for the developing flower, is usually leaf-like and green in appearance.
Sepal
This structure is superior to the sepal, is generally colorful, has a sweet aroma and its function is to attract pollinators.
Petal
This is the female part of the flower with three main structures.
Carpel
This is the sticky structure center of the flower and is the part of the carpel that catches pollen released from the anther
Stigma
This is the slender neck that supports the stigma, it is a part of the carpel.
Style
This structure contains the ovules in the carpel.
Ovary
This is the male part of the flower with two main structures.
Stamen
This is the think stalk located in the stamen.
Filament
This is the terminal sack of the stamen.
Anther
The main function of the stamen is to produce ______ and ______.
Pollen grains and sperm
This type of flower contains all four organs; sepal, petal, stamen and carpel.
Complete flower
This type of flower does not contain all four organs.
Incomplete flower
This type of flower contain both the stamen and carpel.
Perfect flower
This type of flower only contain either the stamen or the carpel.
Imperfect flower
This type of flower contain floral organs that are roughly identical and occur at regular intervals around the center of the flower.
Radial symmetrical flower
This type of flower contains floral organs that do not occur at regular intervals around the center of the flower.
Bilateral symmetrical flower
This is another name for a single flower.
Solitary
These are groups of flowers packed tightly together.
Inflorescence
This color flower attracts birds.
Red
This color flower attracts bees.
Yellow
This color flower attracts moths.
White
This shape of flower provides a landing pad for butterflies.
Flat
This type of flower odor attracts flies and some beetles.
Rotting meat (corpse flower)
This type of flower odor attracts bees.
Sweet
A sporophyte is a _______ that produces spores.
Diploid
A gametophyte is a _______ that produces gametes.
Haploid
Multicellular tissue in which meiosis occurs and haploid spores develop.
Sporangium
This is a male gametophyte.
Pollen grain
Each stamen contains __ microsporangia.
4
This is the female gametophyte.
Embryo sac
This is the transfer of pollen from an anther to a stigma.
Pollination
Process in which water is absorbed and a pollen tube grows.
Germination
This is the union of two different sperm with different nuclei.
Double fertilization
This is the seed container that is derived from an ovary.
Fruit
This is the condition of extremely low metabolic resulting in the temporary suspension of growth and development.
Dormancy
This is the uptake of water due to low water potential of a dry seed.
Imbibition
Selective breeding for desired traits.
Traditional breed
Inserting target genes into an organism’s genome.
Genetic modification
This is a LIFESCYLCLE in which there are multicellular DIPLOID (2n) and multicellular HAPLOID (2n) generations which ALTERNATE, PRODUCING EACH OTHER.
Alternation of Generations
EMBRYO SAC has ___ NUCLEI.
8
1 EGG
2 SYNERGID CELLS
2 POLAR NUCLEI
3 ANTIPODAL CELLS
One sperm fertilizes the egg to form a _________ zygote. (EVENT ONE)
DIPLOID
One sperm combines with 2 POLAR NUCLEI, forming a _________ nucleus. (EVENT TWO)
TRIPLOID
