Հիմնականում ինչի մասին խոսում ենք, ամենաքիչը մեր վիդեոներում վերաբերում են էուկարիոտներին

Over 40 years ago, I was cloning stem cells and one of the first experiments just so blew my mind

Այստեղ այլ բաներ կա, որ կարող ենք խոսել

Ահա, թե ինչ է անում լիզոսոմը

And it's a beautifully complex neuron.

I believe matter begets life

We're taking off.

So if these letters stood for areas of interest, do you know what i mean?

It runs down the rivers, and it feeds the plankton, the little microscopic plant cells in the coastal water.

It can actually make itself glow.

Այսպիսով նրանք անվանեցին որոշներին, ովքեր ունեն կորզիներ, էուկարիոտներ

This is something called an underground forest.

And it could be any type of cell.

This is our paleobotanist, Dr...

And we found only 173 genes common to all 13 organisms.

Really? It's a singlecelled parasite that lives in the intestines of animals.

'In what way have we been using the influence of society, which is probably the most powerful force in human psychology?' 1967 Influence of Biological Environments A Stem Cell Experiment

Think of DNA, cells, galaxies, fruits,

Organisms don't think of CO2 as a poison.

Botany deals with the study of plants.

They'd looked at dental calculus under a microscope, and what they had found was things like pollen and plant starches, and they'd found muscle cells from animal meats and bacteria.

let you know that somebody's probably working there at any given moment, in a very real sense, there are biological sensors within a cell that are turned on only when that cell was just working.

Zoology and botany deal with the study of life.

So when we would look at cells, this is how I really got involved in biology and science is by looking at living cells in the microscope.

Botany is the scientific study of plants.

Then from about 600 to 800 million years ago, multi celled organisms appear.

And we know staph can do amazing things.

So, you could fit ten human cells across the diameter of a human hair.

Plants grow.

I work with really amazing,

I say, Oh, no, I continue.

This is my car, and I'm going to drive around and show off my car.

I spoke to a biologist at the Kirstenbosch Botanical Garden in Capetown to ask him where he thought this remarkable plant came from, and his thought was that if you travel around Namibia, you see that there are a number of petrified forests, and the logs are all the logs are all giant coniferous trees, and yet there's no sign of where they might have come from.

I'd love to have an opinion of a paleobotanist as well.

An example of an organism or two that happens to be quite immortal would be plant seeds or bacterial spores.

Could you, say, instead of using material, can I take some cells along with the material, and remove a damaged piece of tissue, put a bio degradable material on there?

The first person to do this systematically was Linnaeus,

It's also simpler when you go into eukaryotes like ourselves you can just pop out the nucleus and pop in another one, and that's what you've all heard about with cloning.

In time, they could no longer function independently, they behaved entirely for the whole.

So in a male, you have some germ cells, so some of these cells turn into germ cells.

They are able to distinguish kin and non kin.

One can say, OK, what are we made of?

They don't have roots that go into trunks nor to the forest floor.

I'll nicely demonstrate that for you. (Laughter)

Our bodies are comprised of 10 times more microbial cells than our own human eukaryotic cells.
