Like gymnosperms, many grasses and angiosperm trees are wind-pollinated. To conserve energy, these angiosperms do not produce complete flowers (complete flowers have all four of the basic parts). Which part would be unnecessary for wind-pollinated angiosperms?

C. petals

Explanation:

A)fruits

B)sepals

C)petals

D)anthers

E)ovaries

The part that will not be necessary in wind pollinated angiosperm is the petals .

The petal is a part of flower that is usually colorful and primarily function by attaracting insect pollinators to the flower.

Since wind pollinated angiosperms do not need to attract insect for pollination, they do not need the colorful petals. They rely on wind to carry their pollen from their anthers to their stigmas (pollination).

Hence, the correct option is C.

They consist mainly of iron-nickel metal with small amounts of sulphide and carbide minerals. During the decay of radioactive elements in the early history of the solar system, many asteroids melted and the iron they contained, being dense, sank to the centre to form a metallic core.
