Answer:

b. Barring mutation, the two sister chromatids must be identical.

Explanation:

Prior to meiosis, the DNA is replicated so cells enter division with all its chromosomes having two sister chromatids united at the centromere.

DNA replication is semiconservative: the original DNA strands are separated and new strands are synthesized using the original ones as templates. As a result, each sister chromatid is made of one original DNA strand and a newly synthesized DNA strand, and both should be identical to each other.

Retrieve your plant specimens. If you have an Edmentum lab kit, your specimens are a cork section, Zea
Tcecarenko [31]

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.

What must be true about the number of chromosomes in each sex cell (when compared to the number of chromosomes in body cells
Mamont248 [21]

Answer:

The number of chromosomes in sex cell must be haploid (1n) as compared to body cell which is diploid(2n).

Explanation:

Body cells are diploid while the sex cells are haploid. We can say that sex cells contain half number of chromosomes as compared to body cells.
