What is a prokaryote?

Back

A prokaryote is a single-celled organism that lacks a nucleus and other membrane-bound organelles. Examples include bacteria and archaea.

Front

What are lipids?

Back

Lipids are a class of biological molecules that include fats, oils, waxes, and fatty acids. They are important for energy storage and cell membrane structure.

Front

What is genotype?

Back

Genotype refers to the genetic makeup of an organism for a specific trait, representing the alleles inherited from its parents.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the 'powerhouse' of the cell because they produce ATP, the energy currency of the cell, through cellular respiration.

Front

How can a child inherit a recessive disorder if neither parent shows symptoms?

Back

A child can inherit a recessive disorder if both parents are carriers of the recessive allele, even if they do not express the disorder themselves.

Front

What is the difference between phenotype and genotype?

Back

Phenotype is the observable physical and physiological traits of an organism, while genotype is the underlying genetic code that determines those traits.

Front

What are the main components of a cell membrane?

Back

The cell membrane is primarily composed of a phospholipid bilayer, proteins, cholesterol, and carbohydrates, which help regulate what enters and exits the cell.

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.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are biological catalysts that speed up chemical reactions in the body by lowering the activation energy required for the reaction to occur.

Front

What is the structure of DNA?

Back

DNA is a double helix structure composed of two strands of nucleotides, which include a sugar, a phosphate group, and nitrogenous bases (adenine, thymine, cytosine, guanine).
