Study Notes
BIO 101 Study Notes
- Heredity and Evolution: Heredity is the passing of genetic information from one generation to the next, carried by genes—segments of DNA. Different types of heritable traits exist, including physical (eye color, height), physiological (blood type, metabolism), behavioral (instincts, learning tendencies), and disease susceptibility (inherited disorders).
Characteristics and Classification of Living Things
- Seven characteristics of living organisms: These distinguish living things from non-living things:
- Nutrition/Feeding: Organisms obtain energy and materials from their surroundings.
- Respiration: Release of energy from food within cells.
- Sensitivity: Organisms respond to internal or external stimuli.
- Reproduction: Organisms produce offspring of their own kind.
- Growth: A permanent increase in an organism's size or body mass.
- Excretion: Removal of waste products from the organism's body.
- Movement: Organisms' ability to change location.
Characteristics of Living Organisms
- Classification: Organisms are grouped according to structural similarities; from the largest group (kingdoms) to the smallest (species): Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Anaerobic Respiration
- Animals: Some organisms and tissues can respire without oxygen using anaerobic respiration. This process is less efficient than aerobic respiration, but can be crucial for short-term activities or when oxygen is limited. For example, muscle activity.
Classification of Animals
- Artificial Classification: Groups organisms for convenience based on visible features like habitat, movement, or diet.
- Natural Classification: Organisms are grouped based on evolutionary and genetic relationships, taking into consideration many characters to determine natural affinities
Reproduction in Animals
- Sex: Male and female gametes combine their genetic material to reproduce.
- Asexual Reproduction: Offspring are genetically identical to the parent.
- Sexual Reproduction: Creates unique offspring by combining genetic material from two parents
Reproduction in Plants
- Asexual Reproduction: New plants form without the use of seeds. Methods include vegetative propagation, cutting, grafting.
- Sexual Reproduction: Seeds are the main mode, resulting from the fusion of male and female gametes. This often involves pollination (transfer of pollen to stigma) leading to fertilization and fruit/seed formation.
Other topics
-
Taxonomy: The science of naming and classifying organisms into groups based on structural and evolutionary relationships. Two major types of classification are known - artificial and natural.
-
Artificial classifications: Use simplified criteria for grouping organisms, not reflecting phylogenetic relationships
-
Natural classifications: Group organisms based on evolutionary relationships, using a hierarchical structure: Kingdom, Phylum, Class, Order, Family, Genus, Species.
-
Artificial and natural classifications: These are two major approaches to classification. Artificial classification uses few characters to aid in classification. The natural classification uses many more features which helps to reflect the phylogenetic and evolutionary relationships effectively.
