1In land plants, the tiny pores mainly on the underside of leaves through which most water vapor escapes during 蒸散 (transpiration) are called what?
A.stomata (気孔)
B.xylem vessels
C.phloem tubes
D.guard epidermis
Explanation: Transpiration (蒸散) occurs mainly through stomata (気孔), pores bordered by guard cells on the leaf epidermis; opening and closing them regulates water loss and gas exchange.
2A potometer with a leafy shoot is set up indoors. After 1 hour, the water column moved 12 cm. If a fan blowing dry air is directed at the leaves, what change is expected in the next hour?
A.The water column moves a greater distance per hour
B.The water column moves a smaller distance per hour
C.The water column does not move at all
D.The water column reverses direction
Explanation: Dry moving air lowers the water-vapor concentration at the leaf surface, steepening the gradient between inside the leaf and the surrounding air, so 蒸散 (transpiration) increases and the potometer column moves farther.
3The plant organelle in which 光合成 (photosynthesis) primarily takes place is the:
A.chloroplast
B.mitochondrion
C.nucleus
D.vacuole
Explanation: Chloroplasts (葉緑体) contain chlorophyll and host the light-dependent reactions and Calvin cycle of photosynthesis, converting light energy into chemical energy in sugars.
4When an aquatic plant such as Elodea is placed in water and exposed to bright light, the gas that bubbles off the leaves is:
A.oxygen
B.carbon dioxide
C.nitrogen
D.hydrogen
Explanation: In bright light, the rate of photosynthesis exceeds respiration, so oxygen produced from splitting water in the light reactions is released and visible as bubbles.
5Which set lists the overall products of photosynthesis?
A.glucose and oxygen
B.glucose and carbon dioxide
C.starch and carbon dioxide
D.water and carbon dioxide
Explanation: The net reaction of photosynthesis is 6CO2 + 6H2O + light → C6H12O6 (glucose) + 6O2; glucose may later be stored as starch, but the immediate products are glucose and oxygen.
6At the compensation point (補償点) of a plant under a certain light intensity, which statement is correct?
A.The rate of photosynthesis equals the rate of respiration, so there is no net gas exchange with the environment
B.The rate of photosynthesis is zero
C.The rate of respiration is zero
D.The rate of transpiration equals the rate of photosynthesis
Explanation: The 補償点 (compensation point) is the light intensity where CO2 taken up by photosynthesis equals CO2 released by respiration (and likewise O2 release equals O2 use), so net gas exchange is zero and the plant neither gains nor loses dry mass.
7A somatic (body) cell of a pea plant has 14 chromosomes. After this cell undergoes mitosis, how many chromosomes does each daughter cell contain?
A.14
B.7
C.28
D.23
Explanation: Mitosis (体細胞分裂) preserves the chromosome number: each daughter cell receives an identical copy of every chromosome, so 14 chromosomes remain 14 in each daughter cell.
8During mitosis, the chromosomes first become clearly visible as duplicated structures (paired sister chromatids) in which stage?
A.prophase (前期)
B.metaphase (中期)
C.anaphase (後期)
D.telophase (終期)
Explanation: In prophase (前期) the chromatin condenses into visible chromosomes, each already duplicated as two sister chromatids joined at the centromere; the nuclear envelope also breaks down.
9Compared with a parent cell that has 14 chromosomes, a gamete produced by meiosis (減数分裂) from that cell contains:
A.7 chromosomes
B.14 chromosomes
C.28 chromosomes
D.21 chromosomes
Explanation: Meiosis (減数分裂) consists of two divisions with only one round of DNA replication, halving the chromosome number, so a parent with 14 produces gametes with 7.
10Which sequence correctly describes the early development of a sea urchin after fertilization?
A.zygote → cleavage → morula → blastula → gastrula
B.zygote → blastula → cleavage → morula → gastrula
C.zygote → morula → cleavage → blastula → gastrula
D.zygote → cleavage → gastrula → morula → blastula
Explanation: After fertilization the zygote undergoes cleavage (細胞分裂) to form a solid morula, which then develops a cavity to become a blastula (胞胚), and finally involutes to form the gastrula (原腸胚) with germ layers.

About the Nagano Entrance Science Exam

The Nagano Public High School Entrance Selection 理科 paper is created by the Nagano Prefectural Board of Education. The single 50-minute, 100-point written paper, sat on the 後期選抜 academic test day, has four 大問 (生物, 化学, 地学, 物理, 25 points each) on the 2017 MEXT junior-high Course of Study. Nagano runs a two-stage selection (前期選抜 and 後期選抜); this bank targets the 後期選抜 paper, which combines the academic test (500) with the 調査書 (45 points) by 相関図, and there is no fixed pass mark. This page provides 100 original English-language practice questions with detailed explanations as a study adaptation — not an official translation, not a reproduction of the official paper, and not a format simulation of the hand-written experiment-record, calculation, and 記述 sections.

Assessment

The real Nagano 理科 examination is a 50-minute paper scored out of 100 points (500 total across five subjects), sat on the 後期選抜 academic test day (five subjects, 50 minutes each: 国語・数学・社会・理科・英語). It is a written, constructed-response paper in Japanese organized into four 大問 of 25 points each — 生物 (biology), 化学 (chemistry), 地学 (earth science), and 物理 (physics), one 大問 per field. Verified 2025 tendencies include plant 蒸散 and animal 発生/分裂 in biology, density and 酸化銀 thermal decomposition in chemistry, 火山灰 and 金星 observation in earth science, and 電気回路 and 仕事 in physics. Students record experiment observations, do calculations, and write explanations by hand. Nagano runs a two-stage selection (前期選抜 and 後期選抜); this bank targets the 後期選抜 paper. The 後期選抜 combines the academic test (500) with the report card (調査書, 45 points, 中学3年 9教科 × 5段階); selection is by 相関図 (correlation diagram), with no fixed pass mark. Some schools apply 傾斜配点 (weighted scoring). This local bank is an English-language MCQ study adaptation providing 100 original practice items; MCQs cannot simulate the hand-written experiment-record, calculation, and 記述 sections of the real paper.

Nagano Entrance Science Study Tips from Top Performers

1Drill the four fields evenly — the paper has one 25-point 大問 each for 生物, 化学, 地学, and 物理, so a weak field costs a full quarter of the marks.
2Master the core calculations: density = mass ÷ volume, 質量パーセント濃度, Ohm's law (V = IR), electrical power (P = VI), and work (W = Fs); re-check the arithmetic.
3For 溶解度 and 濃度, practice reading solubility curves and computing concentration from mass of solute and solution.
4Review the standard junior-high experiments (plant 蒸散, 酸化銀 decomposition, circuit measurement, 前線 and weather) and be able to explain the method, result, and cause in a sentence.
5For 地学, practice reading 天体 observation and 前線 passage questions, and 地層 formation reasoning.
6Manage the 50-minute paper across all four 大問; secure the basic concept and short-calculation marks first.
