How does the shape of pollen grains in Pinus differ from those in flowering plants? Describe two ways that you could identify whether a plant was monocot or dicot: Which phylum does Zamia belong to? Another characteristic important in plant identification is leaf arrangement, which can be alternate, opposite, or whorled. Insert photos of each leaf type below. What happens to each of the two sperm nuclei in double fertilization?

Step 1
The shape of pollen grains in Pinus differs from those in flowering plants as they have air sacs or air bladders called sacci, which help in wind dispersal. In contrast, flowering plants have various shapes and surface structures, but they generally lack air sacs. Show more…

How are gymnosperms and angiosperms similar? plants in both groups produce flowers and fruits plants in both groups have cones to produce pollen and seeds plants in both groups produce pollen and seeds plants in both groups lack vascular tissue What do seeds contain? an embryo sporophyte and a male gametophyte an embryo sporophyte and nutritive tissue male and female gametophytes a mature sporophyte and an embryo The function of large showy flowers and sugary nectar in flowers is to protect the embryo sporophyte attract seed dispersers attract pollinators attract curious biology students
