1.
Multiple Choice
________ is the process of reproduction involving a single parent that results in offspring that are genetically identical to the parent.
asexual reproduction
sexual reproduction
fertilisation
meiosis
Answer explanation
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and physically similar to the parent or an exact clone of the parent.
2.
Multiple Choice
_____ are the leaflike parts that cover and protect the flower bud.
sepals
petals
anther
stigma
Answer explanation
A sepal is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.
3.
Multiple Choice
The _____ is the pollen-producing male reproductive organ of a flower, consisting of an anther and filament.
stamen
filaments
anther
stigma
Answer explanation
The stamen (plural stamina or stamens) is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium. These are the male parts of the flower. Each stamen is made up of a long filament, with an anther at the top. The anthers contain pollen grains, which contain the male gametes.
4.
Multiple Choice
The ____ is the part of the pistil where pollen germinates.
stamen
filaments
anther
stigma
Answer explanation
The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings.[3] The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals (biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slender to globe shaped to feathery.[4] The stigma (pl stigmas or stigmata)[1] is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower.
6.
Multiple Choice
The _____ is the female reproductive organ of a flower, consisting of the stigma, style, and ovary.
carpel
ovary
stigma
dormant
