The mitochondria are the powerhouse of the cell, as they are responsible for the production of energy in the form of ATP through the process of cellular respiration.
A gene is the basic unit of heredity. Genes are segments of DNA that contain the instructions for the development of traits in an organism.
dRNA is not a type of RNA. The main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight into chemical energy stored in glucose.
Cellulose is the primary structural component of plant cell walls, providing rigidity and strength.
Mushrooms belong to the kingdom Fungi, which includes organisms that decompose organic matter.
Enzymes are proteins that act as catalysts to accelerate biochemical reactions.
The kidneys filter waste products and excess substances from the blood, forming urine.
'Homozygous' refers to having two identical alleles for a particular trait, either dominant or recessive.
