Answer: The answers are:

1- C) S phase

2-A) Prophase, Metaphase, Anaphase, and Telophase.

3-A) A. They help separate the chromosomes.

4)C) A cell plate

Explanation:

1-during the S phase (Synthesis phase) of Interphase. Interphase is basically the daily life cycle of the cell. Cells spend most of their life in Interphase before Mitosis occurs

2-Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in strict sequential order

3 Spindle Fibers equally divide the chromosomes in a parental cell into two daughter cells

4-The cells of land plants, unlike animal cells, have a cell wall made of stiff sugars which surround their cell membranes.

Answer:

Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.

Cells produced in <u>sexual reproduction</u> will have half of the genetic information of body cells and will be genetically <u>unique</u>. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a <u>zygote</u>: the first body of a new individual.

The new individual will now have cells that are <u>diploid</u>, meaning they have two sets of chromosomes. They zygote will have to do a lot of <u>mitosis</u> allowing it to grow quickly and ensure that all of its cells are genetically unique.
