Female cones produce what? Which contain eggs

Lyrx [107]

Answer:

Female cones contain eggs and produce seeds.

Explanation:

Strobiles, also known as cones, are structures commonly confused with flowers, but should not be so named. Found mainly in gymnosperms, strobiles are responsible for the formation of gametes.

Female cones are larger and more complex than male cones. They have egg scales, spiraling around the strobile axis, and these cones produce seeds. At the time of reproduction, the scales of this cone are well separated, ensuring that pollen grains reach the eggs, germinate and produce the pollen tube, which is responsible for bringing the male gamete to the female. It is these strobiles that will house the seed after fertilization.

Refer to the images to identify cytokinesis either by the process of a cleavage furrow or cell plate.

olasank [31]

In cell division, this process involves the fusion of cell to form another cell. Because organisms and organs are made of cells, in order to function, cells divide and replicate.Cytokinesis is the stage where the cell separates its cytoplasm from the main cell and be an independent cell similar to that of the parent cell.
