Classification of Vascular, Nonvascular, Monocot & Dicot Plants

1. Classification of Vascular, Nonvascular, Monocot & Dicot Plants

Plants may not seem like the most interesting things around, but they are definitely useful. In this lesson, we will explore the basic classification of plants and the unique characteristics of each group.

What are the Parts of a Plant?

2. What are the Parts of a Plant?

Ever look at a plant and wonder what each specific part is? A plant has two basic plant parts: the shoot and root systems. In this lesson, you'll learn and be able to identify each individual plant part within the shoot and root systems.

Pollination Process: Male & Female Flower Components

3. Pollination Process: Male & Female Flower Components

In this lesson, we'll learn about the pollination process and the components in plants that make this possible. We'll also learn about the various forms of pollination and how they work.

Asexual Plant Reproduction: Vegetative Propagation and Bulbs

4. Asexual Plant Reproduction: Vegetative Propagation and Bulbs

Not all plants make attractive flowers in order to reproduce. Some plants will not make seeds and pollen either. These plants have other ways to create new offspring. We will look at a few key methods of vegetative propagation.

Seasonal Growth Cycles: Perennial, Annual and Biennial Plants

5. Seasonal Growth Cycles: Perennial, Annual and Biennial Plants

We continue to grow and change throughout our entire lives, living through many seasons and years. Plants have different patterns of growth and development regarding seasons, which we will look at in this lesson.

Plant Hormones: Chemical Control of Growth and Reproduction

6. Plant Hormones: Chemical Control of Growth and Reproduction

We most often think of hormones as things that control our actions and development. However, even plants have these chemicals to help regulate growth and reproduction.

Water Absorption & Movement in Plants

7. Water Absorption & Movement in Plants

In this lesson, you'll learn about the complex process involved in the transport and absorption of water from the roots to the leaves of different types of plants.

Environmental Stimuli & Stress: Plant Adaptations & Responses

8. Environmental Stimuli & Stress: Plant Adaptations & Responses

Plants get stressed out about a lot of stuff, like floods, droughts, high heat, and cold. And they have ways in which they deal with these kinds of stress. This lesson gives some examples of how this occurs.
