This animation by Nucleus shows you the function of plant and animal cells for middle school and high school biology, including organelles like the nucleus, nucleolus, DNA (chromosomes), ribosomes, mitochondria, etc. Also included are ATP molecules, cytoskeleton, cytoplasm, microtubules, proteins, chloroplasts, chlorophyll, cell walls, cell membrane, cilia, flagellae, etc.

Phoenix, Arizona is home to an unusual kind of resident: the Rosy-faced lovebird. The small, brightly colored parrots are popular cage birds, but here in Phoenix they’ve escaped captivity. Over 25 years, they’ve colonized the desert, with a few useful tricks up their sleeves . . . 🌵 ↠Subscribe: https://www.youtube.com/c/Terr....aMaterOfficial?sub_c

Miles away from their natural African habitat, lovebirds have learned to survive with the aid of cacti, water sprinklers, and a couple of helping hands (and beaks). Take a look at the incredible success story of this plucky little escapee.

Transcript of closed captions:

0:05: We are approaching a redwood tree. To animate a scientifically accurate leaf, artists studied the texture of a redwood leaf specimen on a glass slide at high resolution. They even counted the stomata, and used that exact count for this film!

0:25: These leaves would be measured on a centimeter scale. Throughout the animation, we will gradually zoom in to smaller scales.

0:40: As we approach a single stoma, we are now on a millimeter scale.

0:48: As we enter the interior of the leaf, we see many individual palisade cells. These cells are where photosynthesis takes place; they are translucent to allow sunlight to enter.

1:00: As we approach a single palisade cell, we’ll zoom down to the micrometer scale. The shapes inside the cell are organelles: the bright globules at the bottom are the Golgi apparatus; the yellow spotted tubes are endoplasmic reticulum studded with ribosomes.

1:09: That large, blue membrane surrounds the nucleus; the purple blobs are mitochondria.

1:18: The faint, yellow, spider-web structure of the cytoskeleton provides structure and support to the cell.

1:24: You are about to enter a chloroplast; inside you see flat, pancake-like membranous structures called thylakoids. This is where the light-dependent reactions of photosynthesis take place to produce ATP, the cell’s energy carrier molecule. way


1:38: The time scale has changed: the molecules are shown moving 1 million times slower than in real life!

1:42: As we near an individual thylakoid, the animation scale continues to shrink down to the molecular level, where things are measured in nanometers.


1:52: The green and blue bush-like structures are photosystems: clusters of proteins that absorb light energy from the sun and help convert it into the chemical energy that’s stored in the bonds of the energy carrier molecule called ATP.

2:03: The yellow-green, rotating structure is an enzyme called ATP synthase. This molecular machine facilitates the flow of protons down their concentration gradient from one side of the thylakoid membrane to the other, using the energy released in the process to assemble ATP.

2:16: The pulses of light in the thylakoid membrane in which the photosystems are embedded represent energized electrons being passed from one photosystem to another, passing along the energy which will be stored in the bonds of ATP (the classic “bucket brigade”).

2:26: The small “wigglies” are ATP molecules. Living things store energy in the bonds of the ATP molecules and then use that energy to conduct all the processes of life.

This animation is a model, and has its strengths and limitations. In order to model something well, visual artists have to make decisions about what to represent and how best to do so.

The California Academy of Sciences is a renowned scientific and educational institution dedicated to exploring, explaining, and sustaining life on Earth. Based in San Francisco’s Golden Gate Park, it's the only place in the world to house an aquarium, planetarium, rainforest, and natural history museum—plus cutting-edge research programs—all under one living roof.

Aquaponics combines two growing methods, aquaculture and hydroponics, to create a self-contained, well-balanced ecosystem. Fish are fed and raised in a tank and as gravity pulls the wastewater through a hydroponic garden, bacteria feed on the waste, breaking it down into essential nutrients for the plants to grow. The system then returns the cleaned water back to the fish reservoir so the process can begin again.

In this episode, Charles Collins shares his backyard aquaponic and hydroponic gardens where he's able to grow tilapia, leafy greens, peppers, herbs and so much more, all in the suburban desert. Together we grow!

ABOUT PARAGRAPHIC

A story is more than a title. We are a small team of independent filmmakers focused on emerging interests. We love exploring the wide landscape of these enthusiast communities through personal stories from their most passionate creators. The underdog, the obsessed, the misunderstood, the ones who have committed everything to their craft. For them it's more than a hobby; it's a way of life.

From garage bakeries and gourmet mushrooms to vertical farming and worm composting, these stories will elevate your understanding and deepen your appreciation.

Look beyond the impression.
