The food for dicot embryos is stored in the endosperm while food for monocot embryos is stored in the cotyledons.
Explanation;
-The storage of food reserves in angiosperm seeds differs between monocots and dicots.
-Seeds need a supply of food to support the embryo plant until it can collect its own food. In monocots, there is usually a supply of food, called endosperm, inside the seed coat but separate from the cotyledon. In dicots, the cotyledons contain the endosperm.
It makes sense that cell membranes are made of phospholipids because water cant mix in with lipids, so the phospholipids will be able to effectively block out any unwanted water or chemicals suspended in water outside of the cell.
