Essential Elements of the Plant Life Cycle

1. Essential Elements of the Plant Life Cycle

People need essential vitamins, minerals, and proteins to live and reproduce, and plants also have a set of essential elements for similar purposes. This lesson discusses this subject.

Primary Growth of Plants

2. Primary Growth of Plants

In this lesson, you'll learn about how a plant grows taller and how this is different from a plant growing wider. You'll also learn about the types of tissues produced during primary growth and the functions of those tissues.

Secondary Growth in Plants

3. Secondary Growth in Plants

Secondary growth allows woody plants to grow very tall and strong. Growing outward as well as upward provides structure, support, and protection to these plants that they would not otherwise have.

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.

Apical Meristem: Definition & Function

5. Apical Meristem: Definition & Function

Land plants both tall and short need to grow vertically and form shoots that hold their leaves up to the sun and roots that push beneath the soil. This is all possible thanks to apical meristem.

Plant Senescence: Definition & Hormonal Regulation

6. Plant Senescence: Definition & Hormonal Regulation

In this lesson you will learn about senescence, the process of aging, in plants. In particular you'll look at the different hormones involved in the regulation of aging.

Leaf Abscission: Definition & Purpose

7. Leaf Abscission: Definition & Purpose

Every year we see trees drop their leaves in anticipation of winter. This actually has a specific purpose and reason. Abscission occurs in many different plants for a variety of reasons, and in this lesson, we will look at the specifics of abscission.

Vascular Cambium: Function & Definition

8. Vascular Cambium: Function & Definition

A plant's ability to undergo growth is dependent upon the cell division that occurs within its stems, roots, and leaves. Vascular cambium has a major role in this growth. Here we will investigate the definition of vascular cambium and look at its function.

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

9. 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.

Vernalization: Definition & Process

10. Vernalization: Definition & Process

Certain plants have very specific growth requirements. In this lesson you'll learn about a process called vernalization, how it works in nature and how to achieve it artificially.
