Summary
This PDF document covers the factors in the development of the physical self. It explains concepts like heredity (nature), environment (nurture), fertilization, gonads, spermatozoa, ova, zygote, chromosomes, genes, DNA, maturation, and stages of human development, including pre-natal, infancy, babyhood, childhood, puberty, adolescence, and adulthood.

2 Factors of the Development of an Individual 1. Heredity (nature) 2. Environment (nurture) 1. Heredity (nature) - the transmission of traits or characteristics from parents to offspring 2. Environment (nurture) - the sum total of the forces or experiences that a person undergoes from conception to old age. FERTILIZATION - Refers to the meeting of the female sex cells (egg cell) and the male sex cell (sperm cell). GONADS - Is a reproductive organ where the sex cells developed. SPERMATOZOA (singular: spermatozoon) - Male sex cell - Produced in the male gonads called testes. OVA - Female sex cell - Produced in the female gonads known as ovaries. ZYGOTE - It is the fertilized egg cell that contains all the hereditary potentials from the parents. Have you seen a chromosome? What is it looks like? (IN YOUR OWN OPINION) CHROMOSOMES - It is a thread-like structures located inside the nucleus of animal or plant cell. FEMALE - always give the X chromosome MALE – may pass either X or Y chromosome XX – female offspring XY – male offspring GENE - basic unit of heredity. - are small particles in a string-like formation. -within a gene is a substance called Deoxyribonucleic Acid (DNA). Deoxyribonucleic Acid (DNA) - The code of heredity. - Contains information and instructions about the newly created organism and programs the traits that should be inherited. Maturation - Is the unfolding of the inherent traits. STAGES OF HUMAN DEVELOPMENT Pre-natal Period Infancy Babyhood Early Childhood Late Childhood Puberty Adolescence Early Adulthood Middle Age Old Age PRE-NATAL PERIOD Conception to birth. Division: 1. Germinal Stage 2. Embryonic Stage 3. Fetal Stage INFANCY Birth to end of the second week. BABYHOOD End of second week to end of the second year. EARLY CHILDHOOD (Preschool Age) 2-6 years old. LATE CHILDHOOD (Elementary age) 6-10 years old PUBERTY (Preadolescence) 12-13 or 14 years ADOLESCENCE 13 or 14-18 years. EARLY ADULTHOOD 18-40 years. MIDDLE AGE 40-60 years. OLD AGE 60 years to death. PREPARE ¼ SHEET OF PAPER FOR A SHORT QUIZ 1. It refers to the meeting of the female sex cell and male sex cell. 2. What do you call the transmission of traits or characteristics from parents to offspring. 3. It is the sum total of the forces or experiences that a person undergoes from conception to old age. 4.When a sperm cell and egg cell meets, what do they form? 5-6. Give the 2 chromosomes of male and female. 7. It contains genetic information and instructions about the newly created organism. 8. These are small particles in a string- like formation. 9.This stage is from conception to birth. 10. What stage that has age of 14 -18.
