Homework Answers
Ans. (e) 11
Number 11 represents zygote, which will convert into embryo (1), which then further transforms into a diploid sporophyte (3). The sporophyte then produces spores (5) by meiosis (4). The spores then produces gametophyte (7). The ganetophyte produces gametes (9), which fertilizes to form zygote (11).

The following question refers to the generalized life cycle for land plants shown in the figure below. Each number within a circle or square represents a specific plant or plant part, and each number over an arrow represents either meiosis, mitosis, or fertilization. 2n 94 and a. In the figure, the process labeled "2" represents b. Does this diagram represent the life cycle of a heterothallic plant? Explain why or why not.

QUESTION 5 You cross want to create a new hybrid plant. You cross Plant 1 (2n=10) with Plant 2 (2n=14) and generate a generation of hybrid plants. Most of the hybrid plants are infertile, however, you do find a hybrid plant that is fertile. You reason that this plant must have undergone a non-disjunction event that now rendered it fertile. If your reasoning is correct, how many chromosomes does this fertile hybrid plant have? O a. 24 Ob. 12 O...

A plant species X with n=5 chromosomes was crossed with a related species Y with n = 7 chromosomes. The F1 hybrids produced only a few pollen grains, which were used to fertilize the ovules of related species Z with n=7 chromosomes. A few plants were produced from this cross, and all had 19 chromosomes. The F1 hybrids (with 19 chromosomes) were mated with related species W with n=11 chromosomes. A few plants were produced from the cross and all...
