Sunlight does not reach the bottom.
Photosynthetic plants need light to make energy. In deep or turbid lakes the light is absorbed or scattered before it reaches the bottom, so the photic (light) zone ends well above the lake floor and plants cannot photosynthesize there. (In shallow lakes where light does reach the bottom, rooted aquatic plants can and do grow.)
