Function of the parts of an angiosperm Flashcards
What is the function of sepals?
To protect the flower bud
What is the function of petals?
Tend to act as advertisers for the flower, attaining specific characteristics such as placement, size, scent, apperance and more in accordance with it’s form of pollinations. For example angiosperms with bird pollinators tend to ammass petals with the apperance of a colour from the red colour spectrum as this is what these animalia are attracted to.
What is the function of the Carpel?
It is the female reproductive organ of flowers
What is the function of stigma?
The tip of the carple which amasses the male gamete ( pollen ) allowing fertilization to occur. Nevertheless, it is imperative to acknowledge the certitude that in consensus with it’s form of pollinating messenger whether this may be insect pollinated or wind pollinated there tend to be diverging characteristics. Alike a insect pollinated stigma tends to be small, located deep within the flower sanctoning the insect in question to brush past/collect the male gamete or brush past the stigma releasing the gamete from it’s body while it’s sticky composure attains the specific pollen grains. Whereas, on the other hand the feathery stigma which increases the likeylhood of attaining small yet larger quantity of pollen grains tends to be present in wind pollinated flowers. Whilst the stigma tend to be quit prominent and long hanging outisde the flower, allowing the wind current to encounter the male gamete with the stigma.
What is the function of the style?
It is a long tubelike structure which holds up the stigma. Whilst, simultaneously after fertilization allows the male gamete to transifigure a tube down it’s appartus as it is a form of a gateway to the ovary - the chamber which attains the female gamete.
What is the function of the ovary?
The ovary is the chamber to produce and contain the ovules
What is the function of the ovule?
It is the female gamete which has the intent to fuse with the male gamete and supply 50% of it’s DNA towards the offspring which is the product to this fusion. It’s function is to sexually reproduce offspring which is genetically different to it’s parent plants. As this is advanatgeous as it introduces variety into the species while allowing the offspring to be able to adapt to changing enviornments due to the fusion of two DNAs.Which increases the survial for the offspring as well as the species as a whole
What is the function of the stamens?
The function of the stamen which is the male reproductive organ is to provide it’s male gamete to the female gamete whether this may be towards the female reprodcutive organ in another plant for cross pollination or to it’s own plant/ carple for self-reproduction.
What is the function of the anther?
It produces/ supplies towards it’s form of messenger the male gamete which is pollen
What is the function of the filament?
The filament is a fine hair-like stalk waging holds up the anther
What is the function of the nectary?
To make a sugary liquid called nectar which insects or birds feed on. It attracts pollinators to visit the flower
