plant organs: inflorescence in dicots Flashcards
what parts make up the flower structure
corolla, calyx, receptacle, pistil, stamen
what is the corolla and its function
the collection of petals.
can range in amount, shape, colour.
are often showy to attract pollinators
what is the calyx and its function
consists of small, leaf-like structures called the sepals
usually green and perform photosynthesis.
they enclose and protects the flower before it opens
what is the receptacle function
it’s the structure that bears and supports the floral organs. its the base of the flower
what is the pistil
the female reproductive organ.
what is the pistil made up of
the ovary which contains ovule(s), the style and the stigma
what is the function of the stigma
to catch pollen (male gamete)
what is the function of the style
the stalk of the stigma that joins the stigma to the ovary
what is the stamen
the male reproductive organ
what is the stamen made up of
the filament and the anther
what is the filament
the stalk of the stamen
what is the anther
it houses the pollen which is realized upon maturity
what is a complete flower
flowers that contain the typical parts (monocot or dicot)
what does a complete dicot flower contain
receptacle, corolla, calyx, pistil, stamens
what are incomplete flowers
flowers that are missing one or more parts out of the receptacle, corolla, calyx, pistil, stamen
what is a perfect flower
flowers with both male and female parts are called perfect
how can we further classify imperfect flowers
staminate flowers and pistillate flowers
what are pistillate flowers
flowers that only have pistil parts (female reproductive parts)
what are staminate flowers
flowers that only have the stamen parts (male reproductive parts)
compare the differences of monocot reproductive structures and dicots reproductive structures
in monocots: reproductive structure is enclosed in lemma and palea. flowers (called florets) grouped in spikelets
in dicots: reproductive structures usually enclosed in sepals and pedals. arrangement variable
