1Which organelle in a plant cell is the main site of photosynthesis?
A.Chloroplast
B.Mitochondrion
C.Nucleus
D.Vacuole
Explanation: Chloroplasts contain chlorophyll and use light energy to synthesize glucose from carbon dioxide and water. They are found mainly in leaf mesophyll cells. Mitochondria carry out respiration, the nucleus stores genetic information, and the vacuole stores water.
2Which sequence correctly shows the order of events in mitotic cell division?
A.Chromosomes duplicate → they line up at the center → sister chromatids separate → two cells form
B.Chromosomes line up → they duplicate → two cells form → sister chromatids separate
C.Two cells form → chromosomes duplicate → they line up → sister chromatids separate
D.Sister chromatids separate → chromosomes duplicate → they line up → two cells form
Explanation: In mitosis, DNA is replicated first (interphase), then chromosomes align at the cell equator (metaphase), sister chromatids are pulled apart (anaphase), and the cell divides into two (telophase and cytokinesis). This order ensures each daughter cell receives an identical chromosome set.
3In pea plants, round seed shape (R) is dominant over wrinkled (r). What phenotype ratio is expected in the F2 generation of a cross between two F1 hybrids (Rr × Rr)?
A.3 round : 1 wrinkled
B.1 round : 3 wrinkled
C.1 round : 1 wrinkled
D.All round
Explanation: Rr × Rr yields genotypes RR, Rr, Rr, rr in a 1:2:1 ratio. Round (R_) appears in 3 of 4 offspring and wrinkled (rr) in 1 of 4, giving a 3:1 phenotype ratio. This is Mendel's classic monohybrid result.
4A human sperm cell carries either an X or a Y chromosome. What is the probability that a child will be biologically male?
A.1/2
B.1/4
C.3/4
D.1/3
Explanation: Females are XX and produce only X-bearing eggs; males are XY and produce roughly equal numbers of X-bearing and Y-bearing sperm. Fertilization by a Y-bearing sperm produces an XY (male) zygote, so the probability is 1/2.
5Which word equation best summarizes photosynthesis?
A.carbon dioxide + water → glucose + oxygen
B.glucose + oxygen → carbon dioxide + water
C.carbon dioxide + oxygen → glucose + water
D.glucose + water → carbon dioxide + oxygen
Explanation: Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen. The oxygen released comes from water split during the light-dependent stage. The reverse equation describes respiration.
6A leaf is tested with iodine solution after being kept in the dark for two days. What result is expected, and why?
A.Yellow-brown (no starch), because photosynthesis could not occur without light
B.Blue-black (starch present), because stored starch remains in the leaf
C.Blue-black (starch present), because respiration produced glucose
D.Yellow-brown (no starch), because starch was converted to oxygen
Explanation: Without light, photosynthesis stops and stored starch is gradually depleted, so the iodine test shows yellow-brown. Iodine turns blue-black only when starch is present. The dark treatment is a classic way to prove light is required for starch formation.
7In which organelle does aerobic cellular respiration mainly occur?
A.Mitochondrion
B.Chloroplast
C.Ribosome
D.Nucleus
Explanation: Mitochondria are the site of aerobic respiration, where glucose is broken down using oxygen to release energy (ATP). Chloroplasts perform photosynthesis, ribosomes make proteins, and the nucleus stores DNA.
8A seedling is grown with its root pointing downward, then the pot is turned upside down so the root points upward. After a few days, in which direction does the root grow?
A.Downward (toward gravity)
B.Upward (away from gravity)
C.Horizontally along the soil surface
D.It stops growing entirely
Explanation: Roots show positive gravitropism — they grow in the direction of gravity regardless of the seed's orientation. The root bends downward because auxin redistribution causes growth toward the gravitational pull. Stems, by contrast, show negative gravitropism.
9Which tissue transports water and dissolved minerals upward from the roots to the leaves?
A.Xylem
B.Phloem
C.Epidermis
D.Cortex
Explanation: Xylem vessels carry water and minerals upward from roots to leaves. Phloem transports sugars made by photosynthesis to other parts of the plant in both directions. Epidermis and cortex are protective or storage tissues.
10Which set of characteristics describes fish?
A.Gills, scales, fins, lay eggs in water
B.Lungs, hair, four legs, live young
C.Feathers, beak, two legs
D.Moist skin, four legs, lay eggs in water
Explanation: Fish are aquatic vertebrates that breathe with gills, are covered with scales, and use fins for movement. They lay eggs in water and are ectothermic. The other options describe mammals, birds, and amphibians respectively.

About the Kagawa Entrance Science Exam

The Kagawa Public High School Entrance Examination science paper is created by the Kagawa Prefectural Board of Education. The single 50-minute, 50-point paper, sat on March 9, 2027 (Day 1 of the Reiwa 9 general-selection academic test, at 14:30), is a written exam on the 2017 MEXT junior-high Course of Study, covering biology, chemistry, physics, and earth science across four major questions, with short constructed explanations required on a printed answer sheet. Admission combines the 250-point academic test with the 220-point report card on a five-band correlation table, plus an interview. This page provides 100 original English-language practice questions with detailed explanations as a study adaptation — not a simulation of the official format.

Assessment

The real Kagawa science examination is a 50-minute paper scored out of 50 points (250 total across five subjects); in the Reiwa 9 (2027) general selection all five subject papers are sat on a single Day 1, March 9, 2027 (science at 14:30), with Day 2 (March 10, 2027) reserved for the aptitude test (tekisei kensa) and interview (mensetsu), a makeup (tsuiken) on March 13–14, 2027, and general-selection results announced on March 18, 2027 (Thursday). The paper is created by the Kagawa Prefectural Board of Education on the 2017 (Heisei 29) MEXT junior-high Course of Study, covering biology, chemistry, physics, and earth science across four major questions; frequent Kagawa topics include neutralization and ions and batteries, genetics and cell division, photosynthesis, vertebrates, mass calculation in reactions, ionization tendency, pressure, springs, electric current, motion and energy, and electric power, with lettered-choice and short constructed-response items. Admission (general selection, ippan senbatsu) combines the 250-point academic test with the 220-point report card (chōsasho): the two are, in principle, treated equally, each divided into five bands and combined on a correlation table (sōkan hyō), plus an interview for all applicants. This local bank is an English-language MCQ study adaptation providing 100 original practice items.

Kagawa Entrance Science Study Tips from Top Performers

1For chemistry, master neutralization (the HCl + NaOH reaction and what forms after), ionization tendency, and mass-calculation in reactions — Kagawa tests these often, and the mass-calculation items are worked calculations you can score reliably.
2For physics, drill Ohm's law (V = IR) and electric power (P = VI = I²R) together with pressure (P = F/A) and springs (F = kx) — Kagawa's electric-power and pressure items appear frequently and are calculation-based.
3For biology, learn Mendel's laws and the cell-division order, and be ready to explain the photosynthesis mechanism and plant-root growth experiments in your own words.
4For earth science, memorize the causes of seasons and moon phases, the structure of weather fronts, and earthquake and volcano mechanisms — Kagawa's descriptive items ask you to explain the mechanism, not just name it.
