Life Science: Reproduction And Human Development Flashcards
What is the purpose of the phases and stages of the cell cycle?
The purpose is to regulate cell division and ensure proper cell function.
What are the phases/stages of the cell cycle in order?
The phases are Interphase, Mitosis (Prophase, Metaphase, Anaphase, Telophase), and Cytokinesis.
What is the difference between benign and malignant tumours?
Benign tumours are non-cancerous and do not spread, while malignant tumours are cancerous and can invade other tissues.
What are the three types of treatments for cancer?
The three types are surgery, radiation therapy, and chemotherapy.
What are the key differences between Mitosis and Meiosis?
Mitosis produces two identical cells, while Meiosis produces four genetically diverse gametes.
What are the types of asexual reproduction?
Types include Binary Fission, Budding, Parthenogenesis, Fragmentation, Vegetative Reproduction, Grafting, Plant Tissue Cultures, and Spore Formation.
What is the difference between self-fertilization and cross-fertilization?
Self-fertilization involves one organism’s gametes, while cross-fertilization involves gametes from two different organisms.
What is genetics?
Genetics is the study of heredity and the variation of inherited characteristics.
What is the difference between characteristics and traits?
Characteristics are general features, while traits are specific variants of those characteristics.
What is biotechnology?
Biotechnology is the use of living systems and organisms to develop or create products.
What is the role of hormones in human reproduction?
Hormones regulate puberty, gamete production, and reproductive processes.
What is the difference between conception and implantation?
Conception is the fertilization of the egg, while implantation is the embedding of the fertilized egg into the uterine wall.
What is the function of the placenta?
The placenta provides nutrients and oxygen to the developing fetus and removes waste products.
What is the difference between physical and chemical properties?
Physical properties can be observed without changing the substance, while chemical properties involve a change in composition.
What is the difference between a theory and a law in science?
A theory explains why phenomena occur, while a law describes what happens under certain conditions.
