Learn the basics about Photosynthesis and respiration. What is Photosynthesis? How do plants make their own food? Find out more in this video!

We wouldn’t have life without photosynthesis; life processes depend upon it. Not only are photosynthetic organisms the main producers of food, but without photosynthesis Earth’s atmosphere would lose its oxygen. In photosynthesis is that...

hotosynthesis is a chemical reaction that is fundamental to life. In this video we are going to have a look at the factors that affect the rate of photosynthesis. There are 3 main factors: light intensity, carbon dioxide concentration...

Structure Of The Leaf | Plant | Biology | The FuseSchool Plants make food through photosynthesis. Using their leaves, plants combine sunlight, carbon dioxide and water to make glucose and oxygen. A leaf is like a plant's food factory,...

CREDITS Animation and Design: Reshenda Wakefield Narration: Dale Bennett Script: Eleanor Trezise When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules...

Here's an exciting way to learn important facts and get ready for a life science test! In this episode we'll be looking at photosynthesis.

Photosynthesis is a powerful process that is responsible for some of life’s most vital functions. In fact, consumers like us rely on photosynthetic producers to harness energy from the sun so that we can survive and thrive. In this...

SciShow News looks at some of the firsts, highests, and lowests of the year in science.

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...

Paul Andersen explains how pigments can be separated using chromatography. He shows how you can calculate the Rf value for each pigment. He then explains how you can measure the rate of photosynthesis using leaf chads and water...

Explore one of the most fascinating processes plants can do: photosynthesis! In this Amoeba Sisters updated photosynthesis video, you will find a general overview of the light dependent and light independent reactions (Calvin Cycle) and...

Humans produce 300 million tons of new plastic each year -- yet, despite our best efforts, less than 10 percent of it ends up being recycled. Is there a better way to deal with all this waste? Morgan Vague describes her research with...

Humans have relied on fertilizers to grow their plants for thousands of years. But the production of synthetic fertilizers also requires an immense amount of energy that comes primarily from fossil fuels and therefore contributes to...

Plants need sunlight to live, but they also need to block the sun's more harmful rays. Plants can't put on sunscreen or find shade, so how do they avoid getting a gnarly sunburn?

The species of slug known as Elysia chlorotica may not look like much— it resembles a bright green leaf— but it's one of the most extraordinary creatures on our planet. Living in marshes along the coast of North America, it can go about...

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...

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...

The video discusses the process of photosynthesis, how plants make their own food, and the factors that affect the rate of this process. The video explores the impact of light intensity, carbon dioxide concentration, temperature, and the...

This video is answering the question of did Roman children wear jewellery.

Photosynthesis is the process that plants use to convert energy from the Sun into food. In this lecture, I talk about the process of photosynthesis, and show the steps involved in producing glucose.
