Levels of organisation an organism | Cells | Biology | FuseSchool

Our body is a pretty fantastic feat of engineering. But how does it work? How do all of the different components come together to keep us alive, keep us functioning and achieving our goals?
In this video we are going to look at the levels of organisation in organisms, from smaller than cells to bigger than organs.
In unicellular organisms, the single cells performs all life functions. However, multicellular organisms have various levels of organisation within them.
All living things are made up of cells; this is what distinguishes them as living. Cells are the building blocks of life. Inside cells are little organelles.
These are specialised structures that carry out particular jobs or functions. Like in this animal cell, the mitochondria provides energy to the cell. And the ribosomes are involved in protein synthesis.
Cells themselves are the basic structures that make up living organisms.
In multicellular organisms, they are differentiated to carry out different roles. Here are a few specialised human cells...
Groups of cells then function together to form tissues. In humans, we have 4 main types of tissue. And in plants… the xylem and phloem are examples of plant tissues.
When there are layers of tissue working together, they form an organ. Organs are specialised to carry out specific life processes. All animals contain organs. In fact, mammals have five vital organs that they cannot live without: kidneys, lungs, liver, heart, and brain.

But plants have organs too…
These specialised organs work together in organ systems, performing body functions. Organ systems keep the body regulated and in a stable state. The human body has 11 organ systems.
Organisms are entire living things that can carry out all basic life processes. Multicellular organisms are made up of organ systems, but unicellular organisms such as bacteria or protist are made up of one cell.
So there are the levels of organisation in multicellular organisms.
Organelles → cells → tissues → organs → organ systems → organisms

i like how the outro is louder than the actual video

[MrDavidjRay]

If you could make your voice a little louder and bring the music down a hair it would be perfect, but it was very informative and well presented thank you!

[raiyabrown]

POV: your teacher is making you watch this

[mmd_hanyy]

fun fact:



you were forced to come here

[datboi]

If you can't hear what she's saying then turn on the captions. That should help you understand more.

[sarashortcake]

I could barely hear your voice, the overall video was great but the audio was awful, not hating just giving advice 😇

[izaanshaikh]

i only heard '' if you like the video give it a thumbs up and dont forget to subscribe''

[kristasutherland]

Hard to hear - the background music is way too loud

[zoeboik]

does anyone else sit through 9 hours+ of anime but can barely sit through 2 minutes of a video for school?

[FlaviaMartinsUK]

Who ever cannot hear her, you can look in the description box.
It says everything in the vídeo -

[gregorynuttall]

Great content, very bad audio quality.

[redlophix]

Well maybe all of you have to turn the volume up? :D Because then it is completely okay.

[rajamustafa]

It was great for me, thank you so much for such a brief explanation of levels of organization.

[becausehelivees]

who else was surprised at the end of the video 😂

[kenlee]

if u were to take nursing, what structural organization of organism will u be involved the most?

[yushachouhan]

Thank u Very much....it was very helpfull

[helgapavalec]

Awesome that was an great explanation I owe you my grade:)
