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.

Learn about the importance of plants in our daily lives and explore the different groups of plants. Discover how plants provide us with food, oxygen, and nutrients. In this lesson, we will review the definition of a plant and delve into the various types of plants.
