You can determine the age of a tree by looking at its rings.

In this lesson, we will look at the basic structures of stems and explore what causes the rings in a tree trunk. Just like humans, plants need to grow. Why do some plants experience a secondary growth? Why do some plants grow only in height but others grow in height and width? Discover the answers to these questions in this lesson. Leaves may look pretty in the fall when they are changing colors, but they also provide many necessary functions for plants.

In this lesson, we will explore the structures and functions of leaves. Roots of plants can provide support, food and water. We will look at diagrams and photos to see the different parts of roots in order to explain these different functions.

It is easy to see some plants get taller, but it is important to know that plants must also have a strong support that we cannot always see. Root growth helps plants survive and can happen in two ways. 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.

Roots absorb water and leaves release water, but how does water move up a plant? In this lesson, we will look at how this happens in vascular plants, including the importance of xylem, cohesion and transpiration in the process. 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. These natural beauties provide indispensable services to the plants they adorn.

Ever wonder why bees are attracted to specific flowers? We will look at why certain animals are drawn to certain plants and other methods of pollination in this lesson. 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. This lesson will investigate the structure of the flower known as the corolla. The lesson will also explore the variation in this structure as well as its function and importance in plant reproduction. Did you know that the seed of a plant is made of multiple parts?

In this lesson, we will examine the cotyledon of a seed to gain an understanding of what they are and how they function for the new plant. Learn about the function of the cuticle, then test your knowledge with a short quiz. Plant hybridization is nothing new to science; as a species we have been breeding plants together for thousands of years.

Here we will discuss hybrid plants in the classical sense and how this hybridization has helped science. Learn how plants and photosynthesis are a requirement for animal life on our planet. Discover the role of photosystems in this process, and see how plants use light and water to make oxygen and food. Plastids are found in plants and some algae.

They are necessary for essential life processes, like photosynthesis and food storage. Read this lesson to learn about major types of plastids and what they do to sustain life.

In this lesson, you will learn about root hairs, which are the structures that allow a plant to get water and nutrients from the soil. The spongy layer of a leaf may sound odd, but it has an important role in how the leaf functions. Here, you will learn what the spongy layer is, where it is, and what it does. All plants have unique life cycles and requirements in order to survive. One group of plants is known as perennials. In this lesson we will examine types of perennials and view examples of them.

Ever look at a plant and wonder what each specific part is? A plant has two basic plant parts: Here we will look at what agar is, what it is used for, and generally why it is important. Agar resembles gelatin and in most cases is very similar to it. It moves from the male plant to the female plant through a variety of delivery mechanisms. Did you know… We have over college courses that prepare you to earn credit by exam that is accepted by over 1, colleges and universities.

The insects come to the flowers to drink nectar, and they carry pollen from one plant to the next.

When a plant has been pollinated, it creates a seed or lots of seeds. These seeds will make the next generation of plants. You can see germination in action by taking some seeds and putting them on a damp piece of kitchen towel in a dark cupboard. Lots of types of animal only eat plants. They have to be carefully grown and looked after. People who grow plants for people to eat are called farmers. Can you spot all these images in the gallery?
