Key Concepts

Epigenetics

Epigenetics involves modifications, such as DNA methylation and histone changes, that alter gene expression without modifying the underlying DNA sequence. These modifications can be induced by environmental factors, allowing plants to adjust gene expression in response to their surroundings. However, these changes are reversible and do not alter the genetic code itself, which is why environmental information cannot be permanently stored in the DNA sequence.

Genetic Inheritance

Genetic inheritance refers to the transmission of genetic information from parents to their offspring through the DNA contained in gametes. This inheritance mechanism guarantees that the offspring receive a core set of instructions that influence their developmental processes and physiological traits, ensuring continuity of species-specific characteristics.

Environmental Information

Environmental information encompasses the external cues and signals that plants receive from their surroundings, such as variations in light, temperature, humidity, and nutrient availability. This information plays a crucial role in regulating gene expression, influencing growth patterns and developmental responses, and can result in temporary or adaptive changes in physiological processes.

DNA

DNA, or deoxyribonucleic acid, is the molecular blueprint of life. It carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms. The sequence of nucleotides in DNA determines the hereditary traits passed from parents to offspring, providing a stable and consistent set of instructions throughout multiple generations.

Gametes

Gametes are the specialized reproductive cells that contain half the number of chromosomes of a normal body cell. In sexually reproducing organisms like plants, gametes (the egg cell and the sperm cell or its equivalent in plants) combine during fertilization to form a new organism. This process ensures that a blend of parental DNA, stored in these gametes, is inherited by the offspring.
