If you were a jackrabbit in the desert, you'd be glad to stumble across a cactus: the flesh of these plants is a water source for many animals. Known for their spines and succulent stems, cacti of all shapes and sizes have evolved to not...

This video explains the importance of the epidermis in plants, which acts as a protective layer against environmental factors such as injury, water loss, and insect attacks. The epidermis also contains stomata, which allow for gas...

It describes the mechanism of ascent of sap by the theories of root pressure and transpirational pull. It explains the cohesion-tension-transpiration pull model of water transport.

If a plant has enough water, minerals and energy it will grow right? Well sort of… but there is more to it - like why do plants bend towards the light and not just grow straight? And how come the stem grows up but the roots grow down? It...

Plants have developed responses called tropisms. A tropism is a growth in response to a stimulus; so light and water in the plant’s case. There are different types of tropisms: Positive tropisms are when growth is towards the stimulus -...

Paul Andersen explains how nutrients and water are transported in plants. He begins with a brief discussion of what nutrients are required by plants and where they get them. He shows you dermal, vascular and ground tissue in monocot...

Transpiration is the evaporation of water from the aerial parts of a plant (so the leaves and stems). By water evaporating out of these parts - mostly the leaves, a suction pressure is created which draws water up through the plant. This...

In this video, we will be looking at sexual reproduction in plants. Did you know that there are an estimated 390,900 plant species known to science? This diversity of plant species is, in part, due to sexual reproduction. In plants,...

Upon viewing the Plant Parts video series, students will be able to do the following: Recognize that plants have many parts, and that each part performs specific functions. List many different parts of plants that we eat. Describe the...

"Plants have a transport system to move things around.



The xylem moves water and solutes, from the roots to the leaves in a process known as trans

piration.

The phloem moves glucose and amino acids from the...

How does a tall tree draw water from its roots to its leaves? And how does food made in leaves reach the rest of a plant? Discover how plants transport resources via the xylem and phloem. Biology - Plants - Learning Points. Transpiration...

Plants come in all different shapes and sizes. But they all have several structural features in common. Plants belong to the same kingdom, can you remember what the other 4 kingdoms are? In this video you are going to learn about the...

This video is answering the question of what are the stages in the water cycle.

Paul Andersen explains the major plants structures. He starts with a brief discussion of monocot and dicot plants. He then describes the three main tissues in plants; dermal, ground and vascular. He also describes the plant cells...

Professor Harris has written for more than 50 publications over the past 25 years, including the New York Times, Los Angeles Times, Chicago Tribune, New Haven Register, Northeast Magazine, and USA Today. He currently writes a column for...

Video 6 of the Echolocation Unit. In this final segment, students will discover how farmers are using precision farming to adapt to the challenges of climate change. Using an analogy of doing homework with different tools for different...

This lesson explains the basic structure of the leaf with respect to venation, phyllotaxy and leaf type. It also talks about the leaf modifications seen in different plant species.

Florida’s native crocodiles have found an unexpected sanctuary in the cooling canals at Turkey Point Nuclear Power Plant. This fortunate happenstance, along with tireless conservation efforts, are helping these once endangered predators...

Hank introduces us to one of the most diverse and important families in the tree of life - the vascular plants. These plants have found tremendous success and the their secret is also their defining trait: conductive tissues that can...

Join the Amoeba Sisters in their updated plant structure and adaptations video as they discuss the terms vascular vs nonvascular and how they relate to plants before exploring some general categories of plants (bryophytes, seedless...
