Study Notes
Nutrition
- Definition: Process by which living organisms obtain and utilize nutrients for energy, growth, and maintenance.
- Types:
- Autotrophic nutrition: Organisms produce their own food through photosynthesis (e.g., plants, algae).
- Heterotrophic nutrition: Organisms obtain food by consuming other organisms or organic matter (e.g., animals, fungi).
Respiration
- Definition: Process by which living organisms break down glucose to release energy in the form of ATP.
- Types:
- Aerobic respiration: Occurs in the presence of oxygen, producing CO2 and H2O as byproducts.
- Anaerobic respiration: Occurs in the absence of oxygen, producing lactic acid or ethanol and CO2 as byproducts.
Transportation
- Definition: Process by which living organisms move substances within their bodies or between their bodies and the environment.
- Types:
- Circulatory system: Transport of oxygen, nutrients, and waste products through blood vessels (e.g., humans, animals).
- Xylem and phloem: Transport of water, nutrients, and sugars through plant vascular tissues.
Excretion
- Definition: Process by which living organisms remove waste products from their bodies.
- Types:
- Kidneys: Filter waste and excess substances from the blood, producing urine (e.g., humans, animals).
- Leaves: Remove excess water and minerals through transpiration (e.g., plants).
Regulation
- Definition: Process by which living organisms maintain homeostasis and respond to changes in their environment.
- Types:
- Nervous system: Coordinates responses to stimuli through nerve impulses (e.g., humans, animals).
- Hormone regulation: Chemical messengers control growth, development, and metabolism (e.g., humans, animals, plants).
Growth and Development
- Definition: Process by which living organisms increase in size, complexity, and function.
- Types:
- Cell division: Increase in cell number through mitosis and meiosis.
- Differentiation: Specialization of cells into specific types and tissues.
- Morphogenesis: Formation of shape and structure through tissue organization.
Reproduction
- Definition: Process by which living organisms produce offspring.
- Types:
- Sexual reproduction: Combination of genetic material from two parents (e.g., humans, animals, plants).
- Asexual reproduction: Production of offspring from a single parent (e.g., bacteria, protists).
Nutrition
- Autotrophic nutrition occurs through photosynthesis in organisms like plants and algae, producing their own food.
- Heterotrophic nutrition involves consuming other organisms or organic matter for energy, seen in animals and fungi.
- Nutrition is essential for energy, growth, and maintenance in living organisms.
Respiration
- Aerobic respiration breaks down glucose in the presence of oxygen, producing CO2, H2O, and ATP.
- Anaerobic respiration occurs without oxygen, resulting in lactic acid or ethanol and CO2 production.
- Respiration releases energy from glucose in the form of ATP.
Transportation
- The circulatory system transports oxygen, nutrients, and waste products through blood vessels in humans and animals.
- Xylem and phloem tissues transport water, nutrients, and sugars in plant vascular systems.
- Transportation is crucial for maintaining cellular and tissue functions.
Excretion
- Kidneys filter waste and excess substances from the blood, producing urine in humans and animals.
- Leaves remove excess water and minerals through transpiration in plants.
- Excretion removes waste products from the body to maintain homeostasis.
Regulation
- The nervous system coordinates responses to stimuli through nerve impulses in humans and animals.
- Hormone regulation uses chemical messengers to control growth, development, and metabolism in humans, animals, and plants.
- Regulation maintains homeostasis and responds to environmental changes.
Growth and Development
- Cell division increases cell number through mitosis and meiosis.
- Differentiation specializes cells into specific types and tissues.
- Morphogenesis forms shape and structure through tissue organization.
- Growth and development result in increased size, complexity, and function.
Reproduction
- Sexual reproduction combines genetic material from two parents, seen in humans, animals, and plants.
- Asexual reproduction produces offspring from a single parent, found in bacteria and protists.
- Reproduction ensures the continuation of a species.
