Because humans eat both plants and meat
I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)

<span>For the Yanomamo, the most important source of nutrition
for them is cooking plantains or bananas. The main crops that they usually
cultivate are bananas and cassava which are planted in their gardens. When the men
are known to be hunters, fishers and horticulturists, the women are the ones
who cultivate their land or gardens. The diet of the Yanomamo are usually low
in edible salt. </span>
