Study Notes
Eukaryotic Cells and Plant Characteristics
- Eukaryotic cells are found in humans and plants, and are characterized by the presence of a nucleus and membrane-bound organelles.
- Plant cells have a cell wall, a rigid layer made up of cellulose, which helps maintain the cell's shape.
Vascular vs. Nonvascular Plants
- Vascular plants have xylem and phloem, which transport water and nutrients throughout the plant.
- Xylem transports water and dissolved minerals, while phloem transports food.
- Nonvascular plants lack xylem and phloem, are small, simple, and less advanced, and have rhizoids instead of roots.
Types of Vascular Plants
- Gymnosperms are vascular plants that do not produce flowers, but have seeds that provide protection and food for the plant embryo.
- Angiosperms are plants with flowers that attract organisms for pollination, and are more advanced than gymnosperms.
Monocot vs. Dicot
- Angiosperms are categorized based on the number of cotyledons (seed leaves) present.
- Monocots have one cotyledon, and are characterized by flower petals in groups of three and parallel veins in their leaves.
- Dicots have two cotyledons.
Plant Classification and Importance
- Plants are classified based on their characteristics, such as the presence of flowers and the number of cotyledons.
- Plants are essential for human life, providing food, oxygen, and vitamins and minerals.
