vidéo : L'organisme pluricellulaire, un ensemble de cellules spécialisées - 2nde - Madame SVT

This video has helped you to understand the topic of the specialization of cells. You can now leave a like and subscribe to my channel to show your appreciation. If you want to support my work, you can leave a tip here: https://fr.tipeee.com/madame-svt I am also on Instagram: @madame.svt, Facebook: "Madame SVT", and TikTok: https://vm.tiktok.com/ZMd7Ukf1S You can download the revision sheets here: - on the specialization of cells: https://drive.google.com/file/d/15-WprnEhDKVdZLoABHZdkaDfbVfQotn2/view?usp=sharing - on DNA: https://drive.google.com/file/d/1qXktu1XMAbUxowHF64S-1pHZxFtxJ5fB/view?usp=sharing This chapter "The multicellular organism, a set of specialized cells" is part of the theme 1 "The Earth, life and the organization of living things" of the second year curriculum. Knowledge and skills to be mastered, according to the Official Bulletin: - Knowledge: In unicellular organisms, all functions are performed by a single cell. In multicellular organisms, the organs are made up of specialized cells that form tissues and perform specific functions. All cells in an organism are derived from a single cell that is the origin of the organism. They all initially have the same genetic information organized into genes made up of DNA (deoxyribonucleic acid). However, specialized cells only express part of the DNA. - Fundamental concepts: cell, extracellular matrix/wall, tissue, organ; organelle, cell specialization, DNA, double helix, nucleotides (adenine, thymine, cytosine, guanine), complementarity, gene, sequence. - Skills: Make and/or observe microscopic preparations showing animal or plant cells. Observe and analyze electron microscopy images. Distinguish the different scales of life (molecules, cells, tissues, organs, organisms) by giving the order of magnitude of their size. Good revision!

On this principle, each user can choose to give the advertising revenue from their searches on Youcare (which is free for the user) to the association or content creator of their choice. For 2 years, my goal under the name of Madame SVT has been to make knowledge accessible to everyone, always in my discipline of Life and Earth Sciences. It is therefore with great pride that I announce that I have been chosen by Youcare to be one of their first partners as a content creator in the "Sharing knowledge" category! This means that today, you can also help me develop my channel by simply using this search engine rather than another, and that, with your searches, Youcare will give me a share of its profits so that I can develop my project further, buy equipment to improve my YouTube channel and make my videos even more accessible to everyone! You therefore have an excellent, simple and free way to support my work, if you wish. This search engine can be used on a computer, tablet or smartphone, and to set it up directly under my profile, you can use this link: https://bit.ly/2UihjCD! Thank you in advance to everyone.
