Transcript of Our flower's anatomy

Flower Power.. before dissection front side back side receptacle Sepals petals (6cm) Stamen + Carpel the dissection has begun anther (1/10 cm)+ filament (.5cm) pollen grains
1/10 cm Carpel (9 cm) stigma(1 cm) style (approx. 8cm) ovary Ovary with one half removed
lenghth of ovary (.6 cm) Ovary split in half Ovules to small to see DEFINITION STATION!

RECEPTACLE- location where the flower is attached to the stem
SEPAL- a modified leaf of a flowering plant. meant to protect before the flower opens
PETAL- conspicuous part of flower that attracts polinators
STAMEN- pollen proding reproductive part of plants (male)
CARPEL- part of flower that catches pollen and has the ovary at its base (female)
ANTHER- sac in which pollen grains develope found at the top of the stamen
FILAMENT- stalk that holds up the anther
STIGMA- sticky tip of the carpel, captures pollen
STYLE-stalk that connects the stigma to the ovary
OVARY-base of the carpel containing developing ovules
OVULE-egg containing cells The flower is key to reproduction among flowering plants. Flowers have both the male and female reproductive parts. In the stamen the male sperm is held in the anther in the form of pollen sacks that are transmitted by animal polinators attracted by colored and conspicuous petals. The carpel holds the female reproductive parts (ovary, style, stigma) and is responsible for getting the sperm to the eggs for fertilization. As can be seen in flowering plants, the flowers are the masters of reproduction and essentially everything related to reproduction except for the actuall transportation of pollen happens within them. They are even responsible for the eventuall release of seeds after the fertilzied eggs are ready for life on their own!
