[Total = 30 points There are three different life cycle patterns known as Gametic Meiosis, Zygotic Melosis and Sporic Meiosis. All animals undergo 39. Meiosis, whereas all terrestrial plants undergo 40. Meiosis. In lily seeds, the tissue that provides nutrition for the developing embryo is called the , whereas in pine seeds, the tissue that provides nutrition for developing embryos is called the 42. In a moss life cycle, meiosis occurs in a structure called a(n) 43._ cells called 44 _giving rise to uninucleate In organisms that produce both male and female gametes near each other there are two temporal processes that help the organism avoid inbreeding. If the male gametes are matured first, this is an example of 45. 2, whereas if the female gametes are matured first it is an example of In a terrestrial fern life cycle, the haploid generation is 47. homothallic/heterothallic (answer one) when it produces bisexual gametophytes on which male gameles are formed inside of gametangia called 48 while female gametes are formed inside of gametangia called 49. A group of spindle fibers that align perpendicular to the developing cell plate in land plants is known as a 50. , whereas a group of spindle fibers that align parallel to the developing cell plate in Chlorophyte green algae is called a 51.

Answer 1

39.gametic meiosis

40)sporic meiosis

Gametic meiosis is the meiosis that occurs in all animals.In this, instead of immediately dividing meiotically to produce haploid cells, the zygote divides mitotically to produce a multicellular diploid individual or a group of more unicellular diploid cells. Cells from the diploid individuals then undergo meiosis to produce haploid cells or gametes.

Sporic meiosis occurs in terrestrial plants.in this spores are created by diploid sporophytes
