A plant life-cycle consists of two multi-cellular phases known as the ___________. The diploid phase is known as the _____ _____, and the haploid phase is known as the _________. In bryophytes the _________ is the dominant generation, which is different from lycophytes and pteridophytes. Spores are produced via _________ to enter the haploid generation, and __________ produces a zygote to enter the diploid generation.
Homework Answers
A plant life cycle consists of two multicellular phases known as alternation of generations. The diploid phase is known as the sporophye and the haploid phase is known as the gametophyte. In bryophyes, gametophyte is the dominant phase. Spores are produced via meiosis to enter the haploid phase and fertilization produces zygote to enter the diploid generation.

What is true about the life cycle of a land plant? 1. The gametophyte produces spores by meiosis. 2. The life cycle is entirely haploid, so the sporophyte phase does not exist. 3. The sporophyte produces spores by mitosis. 4. The sporophyte produces spores by meiosis. 5. The gametophyte produces gametes by meiosis.

Stages in the life cycle of a plant Recall that plants have unique life cycles that alternative between the sporophyte and gametophyte generation. For the list of events below, place them in order to describe the life cycle of the plant, beginning with the germination of a new plant. Then, decide which stages describe the sporophyte stages and which stages describe the gametophyte stages and label each accordingly. Drag the text blocks below into their correct order. The zygote develops...

my assigned organism is Naked mole rat (Heterocephalus glaber). please type it. The first step in understanding how information is passed from one generation to the next is understanding how cells divide, particularly how the DNA is passed on to the resulting cells. In this discussion, you will describe the life cycle of an animal or plant of your choosing. The animal or plant you choose must have a sexual life cycle (although it may also have an asexual life...

Using the information you have gathered, address the Focus Question: What is the life cycle of a flowering plant? Draw a circular diagram of the life cycle of a flowering plant. Be sure to include the five structures, listed in Table 1, in the proper order (gametophyte, sporophyte, zygote, spore, gamete). Indicate whether each structure is haploid or diploid and the process by which each structure is produced by the previous structure. You should draw male and female gametophytes and...
