Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.

According to the image, X is for attracting pollinators, Y is for the production of pollen, and Z is for the production of eggs
<h3>Parts and functions of flowers</h3>
The image shows the different parts of a typical flower.
X is a petal. Petals are usually colorful and serve to attract insect pollinators to flowers.
Y consists of the anther and the stigma. Both represent the male organ of the flower and produce the male gametes, otherwise known as pollens.
Z consists of the stigma, the style, and the ovary. They all represent the female reproductive organ of the flower. Pollen lands on the stigma, travels through the style, and reaches the ovary. The ovary houses the ovule or the eggs.

Answer:
"The cricket population would increase"
Explanation:
Without mice as a natural predator, there would be no regulation as to how many crickets live in an area, thus there would be an excessive amount of breeding which can lead to mutations and more sick crickets than healthy ones. The mice pick off the sick/ slower ones so the naturally stronger crickets can pass on their genes to future generations.
