Biology FIRST SEMESTER REVIEW QUESTIONS

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water, and releasing oxygen as a byproduct.

Front

What is the equation for photosynthesis?

Back

The correct equation for photosynthesis is: CO2 + light + H2O -> O2 + Sugar.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, which is essential for the photosynthesis process.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life, composed of two strands that coil around each other to form a double helix.

Front

What are the base pairs in DNA?

Back

In DNA, the base pairs are Adenine (A) with Thymine (T) and Cytosine (C) with Guanine (G).

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the complementary DNA strand for 3' AGGTCAGGT 5'?

Back

The complementary DNA strand is 5' TCCAGTCCA 3'.

Front

What type of graph is used to show percentages of a whole?

Back

A pie chart is used to show percentages of a whole.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating mRNA into polypeptide chains.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
