1. Classification of Vascular, Nonvascular, Monocot & Dicot Plants
Plants are a unique and essential organism. The two broad classifications of plants are vascular and nonvascular plants, however, there are several more. Explore what makes a plant monocot vs. dicot and a gymnosperm vs. an angiosperm in this lesson.

2. Structure of Plant Stems: Vascular and Ground Tissue
Learn about the structure of plant stems, such as the shoot and root structure. Learn about basic stem structures, the three types of ground tissue, the two types of vascular tissue, and how the arrangements of vascular tissue are used in botany.

3. Apical Meristem & Primary Shoot System Growth
The shoot system consists of the plant structures that are above ground. The nodes and buds of a plant provide good evidence for the quality of its growth. Explore the different types of buds and growth at the apical meristem in this lesson.

4. Lateral Meristem & Secondary Shoot System Growth
Only found in dicots, secondary growth increases the girth of the stem. Discover meristems, primary and secondary growth, xylem, phloem, vascular cambium, and cork cambium.

5. Structure of Leaves: The Epidermis, Palisade and Spongy Layers
Leaves have important structures that are necessary for sustaining the life of the plant: the cuticles, upper epidermis, palisade layer, and the spongy layer. Explore the structure and function of leaves in this lesson.

6. Primary Root Tissue, Root Hairs and the Plant Vascular Cylinder
Roots are used for the storage of food and the intake of water. This lesson explores types of roots, root cap, epidermis, primary root tissue, root hairs, and the plant vascular cylinder.

7. Root System Growth: The Root Cap, Primary Roots & Lateral Roots
Root system growth in plants is important for structural support and water and nutrient absorption. Explore the different parts and functions of root systems including the root cap and primary and lateral roots.

8. Nitrogen Fixation: Significance to Plants and Humans
Nitrogen fixation is the process of creating ammonia from nitrogen in the atmosphere. Learn about how the survival of humans and plants depends on nitrogen fixation.

9. Xylem: The Effect of Transpiration and Cohesion on Function
Xylem is a type of vascular tissue that transports water and dissolved material. Explore the structure of the xylem and how it transports water through cohesion and transpiration.

10. Phloem: The Pressure Flow Hypothesis of Food Movement
Leaves produce sugars and stems; roots and fruits use these sugars for energy. In this lesson, we will look at how these sugars move throughout vascular plants, including the importance of phloem and the pressure flow hypothesis in the process.

11. Flowers: Structure and Function of Male & Female Components
Flowers contain unique structures depending on whether they are female or male. Discover the various components of both types of flowers as well as how to determine if a flower is complete or incomplete.

12. Methods of Pollination and Flower-Pollinator Relationships
To reproduce, flowers attract pollinators to move pollen from one flower to another using a variety of methods specific to each species. Learn how the different methods of pollination and flower-pollinator relationships help flowers propagate.

13. C4 Plants: Definition, Types & Examples
C4 plants use a specific type of photosynthesis to avoid wasteful photorespiration. Define C4 plants and discover the C4 photosynthesis process and examples of types of C4 plants.

14. Cambium: Definition & Function
Cambium is the group of cells around a plant stem that produces secondary phloem and xylem. Explore the definition and function of cambium and learn about the different types of cambium, including vascular, cork, and unifacial cambium.

15. Plant Meristem: Definition & Function
While difficult to see without a microscope, plants continuously grow through a process of cell division called meristem. Explore the crucial systems of growth in plants, including the apical meristem, lateral meristem, vascular cambium, and cork cambium, and discover how the biological process is similar in animals, including humans.

16. Primary Consumers: Definition & Examples
Primary consumers, usually herbivores, are the organisms that eat the primary producers. Learn about the definition of a primary consumer and explore examples of primary consumers in a food chain.

17. Rhizomes: Definition & Examples
Rhizomes, also known as creeping rootstock, are networks of plant roots that live underground. Study the definition of rhizomes and plants with rhizome systems, including examples and uses.

18. Short-Day Plants: Examples & Explanation
Plants that produce flowers when the length of day is less than the critical photoperiod for the plant are called short-day plants. Learn about real-world examples and explanations of short-day plants.

19. Turgor Pressure in Plants: Definition & Overview
In plants, turgor pressure makes the tissue inside plants inflexible, preventing leaves and flowers from wilting. Explore the definition and overview of turgor pressure in plants. Learn how it works, and review the hypertonic, hypotonic, and isotonic solutions, as well as osmosis.

20. What is Lichen Planus? - Causes, Symptoms & Treatment
Lichen planus is a skin condition that can look and feel uncomfortable. In this lesson, we will explore lichen planus, including the causes, symptoms, and treatment.
