Many gymnosperms have specialized reproductive structures (cones and strobili) which, in part, have functions similar to angiosperm flowers, although of course they are not homologous with flowers. Some are conspicuous and colorful, even. And there are many gymnosperms which have structures analogous (but not homologous) with angiosperm fruit.
(Note that the modern view is that extant gymnosperms, the Acrogymospermae, form form a clade; the angiosperms are thought to have evolved from a gymnosperm ancestor; so that the Gymnospermae lato sensu are a paraphyletic grade. Hat tip to Jack Aidley for pointing this out; Wikipedia agrees, quoting M.J.M. Christenhusz, J.L.Reveal, et al. "A new classification and linear sequence of extant gymnosperms", in Phytotaxa 19:55–70, 2011, doi:10.11646/phytotaxa.19.1.3.)

An aril (pronounced /ˈærɪl/), also called an arillus, is a specialized outgrowth from a seed that partly or completely covers the seed. [...] The aril may create a fruit-like structure, called (among other names) a false fruit. [...] Such arils are also found in a few species of gymnosperms, notably the yews and related conifers such as the lleuque and the kahikatea. Instead of the woody cone typical of most gymnosperms, the reproductive structure of the yew consists of a single seed that becomes surrounded by a fleshy, cup-like covering. This covering is derived from a highly modified cone scale. (Wikipedia, s.v. Aril)
