Plant Tissue Compartments & Transport

1. Plant Tissue Compartments & Transport

This lesson goes over three ways substances like water and solutes can be transported from cell to cell in a plant: the symplastic, apoplastic, and transmembrane routes.

What are Plasmolysis & Deplasmolysis?

2. What are Plasmolysis & Deplasmolysis?

In this lesson, you'll learn what happens during plasmolysis and deplasmolysis and their relationship to water balance in plants. You'll also learn where these processes occur in everyday life.

Transporting Solutes & Water in Plants

3. Transporting Solutes & Water in Plants

How do plants move water and nutrients where they need to go? That's the question we'll be exploring in this lesson as we look at both xylem and phloem transportation systems and see how plants stay hydrated and energized.

How Solutes and Pressure Affect Water Potential in Plants

4. How Solutes and Pressure Affect Water Potential in Plants

Plants are great at using and moving water. In this lesson, we'll explore the concept of water potential as it applies to plants and check out how solutes and pressure can both impact the total water potential within an organic system.

What Is Transpiration in Plants? - Definition, Rate & Process

5. What Is Transpiration in Plants? - Definition, Rate & Process

Did you know that plants 'sweat?' Transpiration is both an important and costly process for plants, and it requires that a delicate balance between it and other necessary cellular processes be maintained.

Essential Elements of the Plant Life Cycle

6. 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.

The Nitrogen Cycle: Definition, Facts & Steps

7. The Nitrogen Cycle: Definition, Facts & Steps

Oh the places we'll go on our nitrogen cycle tour! Nitrogen is an element that cycles through you, me, plants, and other organisms. This lesson will not only follow nitrogen on this cycle, but will also share some nitrogen facts!

Nitrogen Fixation: Significance to Plants and Humans

8. Nitrogen Fixation: Significance to Plants and Humans

Almost 80% of our atmosphere is nitrogen, but we can't use it. We will look at how this unusable nitrogen is converted into a form we can use and why nitrogen is important to plants and humans.

Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products

9. Photolysis and the Light Reactions: Definitions, Steps, Reactants & Products

In this lesson, we'll learn how electrons get excited during the light-dependent reactions of photosynthesis, jumping off photosystem reaction centers like they were trampolines! In addition, we'll learn how the splitting of water creates reactants for this part of photosynthesis while creating a little fresh air for us.

Dark Reactions of Photosynthesis: The Calvin-Benson Cycle

10. Dark Reactions of Photosynthesis: The Calvin-Benson Cycle

Photosynthesis starts out using the energy from sunlight to get things started, but it ends with the dark reactions, which don't need sunshine to complete sugar production. In the Calvin cycle, ATP and NADPH from the light reactions are used to produce sugars.

Environmental Factors That Impact Photosynthesis

11. Environmental Factors That Impact Photosynthesis

What is photosynthesis? Learn about the environmental factors that affect the rate at which photosynthesis happens. Then, take a quiz to test your understanding.

Cellular Respiration in Plants

12. Cellular Respiration in Plants

In this lesson, we'll learn what cellular respiration is and the role it has in plants. We'll cover what is used and made in cellular respiration and why plants need it.

How a Plant Body Develops

13. How a Plant Body Develops

View this lesson to learn how plants develop. Discover the terms that describe how a plant goes from seed to full-grown plant. Learn what goes on at the cellular level as the plant grows.

Plant Hormones: Chemical Control of Growth and Reproduction

14. 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.
