Document Summary
Choose the answer that is most correct: microsporangia in flowering plants are located in the, stamen, carpel, petals, sepals, receptacle. Flowering plants are found in two main groups: monocots and dicots (eudicots) Multiples of 3 / multiples of 4 or 5. One pore / 3 or more furrows. Scattered vasculature, no secondary growth / ringed vasculature, secondary growth.

They have adapted various strategies: to move male gametes around, to disperse seed. Early plants have spores in water which swim to mate, but now they have adapted new ways to find mates such as airborne ways. 6 stamens that produce pollen which are attached by a filament tip which is the anther. Monocotyledons have 3 sepals that over-lap 3 petals. Has diploid sporophyte cells, cell wall is replaced by callose (betta 1,3 linkages and the molecule forms a helix)
