has-large-font-size\">\n<li><strong>Wind<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Light and small seeds with wings or hairs (e.g., dandelion, maple).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Water<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Seeds that float or have waterproof coverings (e.g., coconut, lotus).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Animals<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Seeds with hooks or sticky surfaces cling to animals (e.g., burdock).<\/li>\n\n\n\n<li>Edible seeds are dispersed after being eaten by animals (e.g., berries, guava).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Explosion<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Some plants have pods that burst open, scattering seeds (e.g., pea, balsam).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Gravity<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Heavy seeds fall directly beneath the parent plant and
