Front

What is 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 gas is produced by plants during photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis.

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic instructions used to make proteins.

Front

What is crossing over in meiosis?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I of meiosis, leading to genetic variation.

Front

How many alleles does an offspring inherit from each parent for a single gene?

Back

An offspring inherits one allele from each parent for a single gene.

Front

What can cause enzymes to denature?

Back

Enzymes can denature due to extreme temperatures or pH levels, which alter their shape and function.

Front

What is the function of enzymes in biological reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is a tetrad in meiosis?

Back

A tetrad is a structure containing four chromatids that forms during Prophase I of meiosis when homologous chromosomes pair up.

Front

What is the significance of genetic variation?

Back

Genetic variation is important for evolution and adaptation, allowing populations to survive changing environments.
