NSG 530 STUDY GUIDE Patho Quiz 1 Graded A+.
Question 1
A human cell can be categorized into which of the following?
A) Gametes and somatic cells
B) Diploid and haploid cells
C) Prokaryotic and eukaryotic cells
D) Mitotic and meiotic cells
Answer: A) Gametes and somatic cells
Explanation: Human cells are categorized into gametes (sperm and
egg cells) and somatic cells (all other cells). Gametes are haploid,
and somatic cells are diploid.
Question 2
How many chromosomes are in a human somatic cell?
A) 23
B) 46
C) 92
D) 22
Answer: B) 46
Explanation: Human somatic cells contain 46 chromosomes
arranged in 23 pairs. These are diploid cells, with one chromosome
from each parent per pair.
,Question 3
How many chromosomes are in a human gamete?
A) 23
B) 46
C) 92
D) 22
Answer: A) 23
Explanation: Human gametes are haploid cells containing only one
member of each chromosome pair, for a total of 23 chromosomes.
Question 4
What type of cell division produces somatic cells?
A) Meiosis
B) Mitosis
C) Both A and B
D) None of the above
Answer: B) Mitosis
Explanation: Somatic cells are formed through mitosis and
cytokinesis. Meiosis produces gametes.
Question 5
What type of cell division produces gametes?
,A) Meiosis
B) Mitosis
C) Both A and B
D) None of the above
Answer: A) Meiosis
Explanation: Gametes are formed from diploid cells by meiosis,
which reduces the chromosome number by half.
Question 6
What is the term for a cell that has two sets of chromosomes?
A) Haploid
B) Diploid
C) Triploid
D) Tetraploid
Answer: B) Diploid
Explanation: A diploid cell has two sets of chromosomes (46 in
humans). Haploid cells have one set (23 in humans).
Question 7
What is the term for a cell that has one set of chromosomes?
A) Haploid
B) Diploid
, C) Triploid
D) Tetraploid
Answer: A) Haploid
Explanation: A haploid cell has one set of chromosomes (23 in
humans). Diploid cells have two sets (46 in humans).
Question 8
During which phase of meiosis do homologous chromosomes pair and
form synapses?
A) Prophase I
B) Metaphase I
C) Anaphase I
D) Telophase I
Answer: A) Prophase I
Explanation: During prophase I of meiosis, homologous
chromosomes pair and form synapses, a step unique to meiosis.
Question 9
What is the result of meiosis I?
A) Two diploid daughter cells
B) Four haploid daughter cells
C) Two haploid daughter cells
D) Four diploid daughter cells
