Life Cycles of Different Types of Plants

1. Life Cycles of Different Types of Plants

From spores to gametophytes to flowers, plants have many different life cycles. This lesson will focus on the life cycles of three groups of plants: the flowering angiosperms, the ferns and the mosses.

Flowers: Structure and Function of Male & Female Components

2. Flowers: Structure and Function of Male & Female Components

In this lesson, we'll look at the parts of a flower and learn their functions. These natural beauties provide indispensable services to the plants they adorn.

An Angiosperm Life Cycle: Flowering Plant Reproduction

3. An Angiosperm Life Cycle: Flowering Plant Reproduction

When you think of how plants reproduce, you probably think of flowers. We will look at how flowering plants use specialized reproductive structures to complete an alternation of generations life cycle.

What is Seed Germination? - Definition, Process, Steps & Factors

4. What is Seed Germination? - Definition, Process, Steps & Factors

This lesson is about seed germination, the process of seeds growing into plants. In this lesson, we'll go over the steps of germination, and what factors influence how seeds germinate.

Asexual Plant Reproduction: Vegetative Propagation and Bulbs

5. 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.

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.

Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

7. Tropisms: Phototropic, Geotropic and Thigmotropic Plant Growth

Animals aren't the only things that can respond to the environment. While plants may seem inanimate at times, they, too, can respond to the environment in order to better survive.

Photoperiodicity: Short-day, Long-day and Day-Neutral Plants

8. Photoperiodicity: Short-day, Long-day and Day-Neutral Plants

Ever wonder why some plants will bloom in the spring but others in the summer? The length of daylight can influence when a flower will bloom. We will look at how the amount of sunlight regulates when plants produce flowers.
