Answer:
Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type.
Stem cells can become a variety of types of cells, while differentiated cells like red blood cells are fully specialized cell types. ... A stem cell produces a mesoderm cell, which can then further differentiate to form a muscle stem cell. From there it differentiates into a smooth muscle cell.
Answer:
poliinators and flagellated sperm
Explanation:
Cycads (phylum Cycadophyta) together with Ginkgophyta, Gnetophyta, Pinophyta, Pteridospermales and Cordaitales belong to the gymnosperms (naked seed-producing plants). They are different than angiosperms which produce encased seeds within an ovary.
Cycads (but also Ginkgo) produce swimming sperm that is different than all other groups which produce sperm without swimming flagella.
Also, unlike other groups of gymnosperms, cycads have specialized pollinators, beetls.
