Telangana SSC Biological Science Answer Key 2025

The answer key for the TS SSC Biological Sciences exam 2025 is provided below. Students can use it to verify their answers and estimate their scores in exam.

Section - I (Very Short Answer Questions)

Q1: Write two chemicals required to conduct an experiment to prove that ‘Carbon dioxide is necessary for photosynthesis.’

Answer:
The two chemicals required for this experiment are:

(i) Potassium Hydroxide (KOH) – It absorbs carbon dioxide.

(ii) Iodine Solution – It is used to test the presence of starch.

Q2: Write two suggestions that you would give to a person whose both kidneys stop working completely.

Answer:

(i) Undergo dialysis – This helps in filtering waste from the blood artificially.

(ii) Consider a kidney transplant – A permanent solution to restore kidney function.

Q3: What will happen if pollutants enter into the lake ecosystem?

Answer:

• Water pollution will increase, affecting aquatic life.
• Decreased oxygen levels may lead to the death of fish and other organisms.
• Algal blooms may occur, disrupting the balance of the ecosystem.

Section - II (Short Answer Questions)

Q4: Explain the steps of the light-dependent reaction in the mechanism of photosynthesis.

Answer:
The light-dependent reaction, also known as the light reaction, takes place in the thylakoid membranes of the chloroplast. The key steps include:

(i)Absorption of Light Energy – Chlorophyll absorbs sunlight, exciting electrons.

(ii)Water Splitting (Photolysis) – Light energy splits water molecules into oxygen, protons (H⁺), and electrons (e⁻). Oxygen is released as a byproduct.

(iii)Electron Transport Chain (ETC) – Excited electrons move through proteins, helping to produce ATP and NADPH.

(iv)ATP and NADPH Formation – The energy from electrons is used to form ATP (energy) and NADPH (reducing power), which are used in the Calvin cycle (light-independent reaction).

Q5: Write any four non-renewable resources you have observed in your surroundings and write their uses.

Answer:

(i)Coal – Used for electricity generation and in industries.

(ii)Petroleum (Crude Oil) – Used to make fuels like petrol and diesel for vehicles.

(iii)Natural Gas – Used for cooking and heating purposes.

(iv)Minerals (Iron, Copper, etc.) – Used in making machinery, construction, and electrical wiring.

Q6: Observe the given picture and answer the following questions.

(i) What type of cell division does it represent?

Answer:

The image represents meiosis, a type of cell division that reduces the chromosome number by half.

(ii) What is the difference in the number of chromosomes of a parent cell when compared to daughter cells?

Answer:

The parent cell is diploid (2n), while the daughter cells are haploid (n), meaning the chromosome number is halved after meiosis.

(iii) In which cells of the body does the above cell division take place?

Answer:

Meiosis occurs in reproductive cells (gametes), such as sperm cells in males and egg cells in females.

(iv) How many daughter cells are formed in the above cell division from a single parent cell?
Answer:

A single parent cell undergoes two successive divisions in meiosis, forming four haploid daughter cells.
