Xylem flytter vand og opløste stoffer, fra rødderne til bladene i en proces kendt som transpiration. Floem flytter glukose og aminosyrer fra bladene rundt om planten, i en proces kendt som translokation. Xylem og phloem er arrangeret i grupper kaldet vaskulære bundter. Arrangementet er lidt anderledes i rødderne til stilkene. Xylem består af døde celler, hvorimod floem består af levende celler. Tilmeld dig FuseSchool-kanalen for mange flere pædagogiske videoer.

Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In this video we look at how to simplify algebraic fractions, and how to add and subtract them. VISIT us at www.fuseschool.org, wh
CREDITS Animation & Design: Peter van de Heuvel Narration: Lucy Billings Script: Lucy Billings The word polygon comes from Greek. Poly means “many” and Gon means “angles”. Polygon = many angles. Polygons are 2-dimensional shapes, that are made of straight lines, with all the sides joined up. VISIT
In algebra we have lots of different names for different things: expressions, equations, formulae and identities are all slightly different versions of similar things. Then within these, we have variables, constants, coefficients and exponents to describe the different parts. We also need to know wh
