Study Notes
Characteristics of Living Organisms
- Living organisms exhibit a range of characteristics that distinguish them from non-living matter.
- These characteristics include: organization, metabolism, growth and development, responsiveness, adaptation, reproduction, and homeostasis.
Photosynthesis
- Plants are autotrophs, meaning they can produce their own food through the process of photosynthesis.
- Photosynthesis uses sunlight, carbon dioxide, and water to create glucose (a type of sugar) and oxygen.
Respiratory System
- The respiratory system is responsible for the intake of oxygen and the release of carbon dioxide.
- This exchange of gases is essential for cellular respiration, where energy is extracted from glucose.
Basic Unit of Life
- The cell is the basic unit of life.
- All living organisms are composed of one or more cells.
Systems and Functions
- The digestive system breaks down food into smaller molecules that can be absorbed by the body.
- The circulatory system transports blood, oxygen, nutrients, and waste products throughout the body.
- The nervous system receives sensory information from the environment and coordinates responses.
- The muscular system allows for movement and provides support.
- The skeletal system provides support, protection, and allows for movement.
- The endocrine system produces hormones that regulate various bodily functions.
- The immune system protects the body from disease-causing organisms.
- The excretory system removes waste products from the body.
- The integumentary system provides protection, regulates temperature, and receives sensory information.
- The reproductive system is responsible for sexual reproduction.
