Study Notes
Cell Specialization
- Cell specialization, or differentiation, transforms generic cells into specific cells that perform unique functions.
- This process is crucial during embryonic development, allowing for the formation of diverse cell types.
Unicellular Organisms
- Unicellular organisms are composed of a single cell, examples include protozoans and some algae.
- These organisms carry out all life processes within one cell.
Multicellular Organisms
- Multicellular organisms consist of multiple cells working together, enabling complex structures and functions.
- This organization allows for specialization and division of labor among cells.
Xylem
- Xylem is a type of vascular tissue in plants that transports water and dissolved nutrients from the roots to the rest of the plant.
- It contributes to the formation of woody structures in stems, providing support and stability.
Phloem
- Phloem is a vascular tissue that carries sugars and other metabolic products downward from the leaves, distributing energy throughout the plant.
- It plays a vital role in plant metabolism and growth.
Stem Cells
- Stem cells possess the ability to differentiate into various cell types, acting as a repair mechanism for tissues in the body.
- Two primary types of stem cells exist: embryonic stem cells, which can form any cell type, and adult stem cells, which have a more limited range of differentiation.
Tissue
- Tissue is a collection of specialized cells that work together to perform specific functions within plants and animals.
- Different types of tissues include muscle tissue, nervous tissue, and connective tissue, each serving distinct roles.
Organs
- Organs are self-contained structures within an organism that perform essential functions, like the heart for circulation and the liver for detoxification.
- Each organ comprises different tissues working synergistically.
Organ Systems
- An organ system consists of groups of organs that collaborate to fulfill particular biological functions, such as the digestive system or respiratory system.
- Each system is composed of specific tissues and contributes to overall homeostasis and health in the organism.
