Leto [7]

In studying the brains for violent repeat offenders, researchers found that their brains had eleven percent less frontal lobe tissue than a normal brain.
In this results, it helps to explain why these people do exhibit deficits in cognitive functions. For example, inhibition, organization, and planning.

X- production of eggs

Y- pollen production

Z- pollen transfer

Answer:

X- attraction of pollinators

Y- production of male sex cells

Z- egg production

Explanation:

Flowers are reproductive structures in charge of sexual reproduction through the production of seeds.

Z, Feminine reproductive structures:

The central structure is known as a carpel, also recognized as the pistil.
The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.
The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.
The ovary and the stigma are connected by a filament named style.

Y, Masculine reproductive structures:

The pollen grains, or male sex cells, are produced in the stamens.
The stamen has an anther where the pollen is produced, and a filament that provides support.

When mature, pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick. Once in the stigma, the pollen grains move to the ovary, where they meet the egg and fertilize. The zygote develops in the ovary.

X, External non-reproductive structures:

Flowers also have external structures known as petals and sepals. These structures are modified leaves whose principal function is to protect the flower´s fertile parts and attract pollinators. Petals characterize as having many different colors that make the flower more attractive to insects and some animals. When they visit a flower searching for their recompense, the flower´s pollen grains transfer to the insect´s body. The insect transports the pollen to the next visited flower, leaving it in the stigma of the second flower.
