Anafase
- C.
Interfase
- D.
Metafase
- E.
Telofase
Correct Answer
C. InterfaseExplanation
During the cell cycle, the chromosomes are not found in the interphase stage. Interphase is the longest stage of the cell cycle where the cell prepares for division by growing, replicating its DNA, and carrying out normal cellular functions. It is during the interphase that the chromosomes are duplicated and appear as long, thin chromatin fibers. The chromosomes become visible and condensed only during the subsequent stages of mitosis, such as prophase, metaphase, anaphase, and telophase. Therefore, the correct answer is interphase.Rate this question:

Amoeba
Correct Answer
E. AmoebaExplanation
Amoeba is a single-celled organism that reproduces asexually through a process called binary fission. During binary fission, the nucleus of the amoeba divides into two, followed by the division of the cytoplasm, resulting in two identical daughter cells. This process does not involve meiosis, which is a type of cell division that produces gametes with half the number of chromosomes. Therefore, amoeba is able to reproduce without undergoing meiosis.Rate this question:

Correct Answer
B. Profase IExplanation
During the process of meiosis, synapsis occurs during prophase I. Synapsis is the pairing of homologous chromosomes, where they come together and form a structure called a tetrad. This allows for the exchange of genetic material between the homologous chromosomes through a process called crossing over. This genetic recombination is important for creating genetic diversity in the offspring. Therefore, the correct answer is prophase I.Rate this question:

Correct Answer
B. MitosisExplanation
The correct answer is mitosis. Mitosis is the process of cell division in which a parent cell divides into two identical daughter cells. In the context of plants, the cambium cells undergo mitosis to produce new cells for growth and development. This process allows for the formation of secondary xylem and phloem, which contribute to the increase in girth of the plant stem. Amitosis, sinergid, endosperm, and embrional are not related to the process of cell division in the cambium of dicot plants.Rate this question:

- E.
Sitokinesis dan kariokinesis secara bergantian sebanyak tiga kali
Correct Answer
D. Kariokinesis tiga kali berturut-turutExplanation
The correct answer is "kariokinesis tiga kali berturut-turut". This means that the young organism's nucleus undergoes three consecutive rounds of division. This process is known as kariokinesis, which ensures that each daughter cell receives a complete set of chromosomes. By undergoing kariokinesis three times, the young organism can produce four cells, each with a haploid set of chromosomes, which is the result of the megasporangium division. Therefore, this answer accurately describes the process of division in the young organism's nucleus.Rate this question:
