style=\"color:#000060\">1. <strong>Wind (Anemochory)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>How it works<\/strong>: Seeds are carried by the wind to different areas.<\/li>\n\n\n\n<li><strong>Characteristics of wind-dispersed seeds<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Light weight<\/strong>: Seeds are often small, light, or have wings or hairs that help them float in the air.<\/li>\n\n\n\n<li><strong>Examples<\/strong>: Dandelions, maple trees, and cottonwood trees.<\/li>\n\n\n\n<li><strong>Advantages<\/strong>: Can spread seeds over long distances, helping plants colonize new areas.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3

(Hydrochory)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>How it works<\/strong>: Seeds are dispersed by water through rivers, lakes, or oceans.<\/li>\n\n\n\n<li><strong>Characteristics of water-dispersed seeds<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Buoyant<\/strong>: Seeds are often light and have a hard outer coating that prevents them from absorbing water.<\/li>\n\n\n\n<li><strong>Examples<\/strong>: Coconut, water lilies, and mangroves.<\/li>\n\n\n\n<li><strong>Advantages<\/strong>: Water dispersal can reach distant shores and islands.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-86f042a2579f1eece033e64cb377e01a\" style=\"color:#000060\">3. <strong>Animals (Zoochory)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>How it works<\/strong>: Seeds are dispersed by animals in different ways:\n<ul class=\"wp-block-list\">\n<li><strong>External Dispersal<\/strong>: Seeds attach to the fur or feathers of animals.<\/li>\n\n\n\n<li><strong>Internal Dispersal<\/strong>: Seeds are eaten by animals and later excreted in a different location.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Characteristics of animal-dispersed seeds<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Hooks and Barbs<\/strong>: Seeds have spines or hooks that cling to animal fur.<\/li>\n\n\n\n<li><strong>Fleshy Fruits<\/strong>: Some seeds are enclosed in juicy, sweet fruits that attract animals to eat them.<\/li>\n\n\n\n<li><strong>Examples<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>External<\/strong>: Burdock (seeds cling to fur).<\/li>\n\n\n\n<li><strong>Internal<\/strong>: Berries eaten by birds (e.g., strawberries, tomatoes).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Advantages<\/strong>: Animals can carry seeds to new areas, even across barriers like mountains or rivers.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-1f63ddfa64f3f6295e05cd463e7fe787\" style=\"color:#000060\">4. <strong>Gravity (Barochory)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>How it works<\/strong>: Seeds fall from the plant to the ground due to gravity.<\/li>\n\n\n\n<li><strong>Characteristics of gravity-dispersed seeds<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Heavy or large<\/strong>: These seeds are often heavy or large and fall near the parent plant.<\/li>\n\n\n\n<li><strong>Examples<\/strong>: Acorns, apples, and chestnuts.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Advantages<\/strong>: Seeds are placed directly under the plant, ensuring good growth conditions if they fall on fertile soil.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-65c7d349906ca0ef0b7efcb5df55646c\" style=\"color:#000060\">5. <strong>Explosions (Autochory)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>How it works<\/strong>: Some plants release seeds with a forceful mechanism, often causing the seeds to be ejected at a distance.<\/li>\n\n\n\n<li><strong>Characteristics of explosion-dispersed seeds<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Mechanism<\/strong>: The seed pods burst open when they dry out, launching seeds into the air.<\/li>\n\n\n\n<li><strong>Examples<\/strong>: Peas, witch hazel, and poppies.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Advantages<\/strong>: Explosive dispersal helps spread seeds rapidly in all directions.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-e508847b84f3edd2e4c83d511fbdd1af\" style=\"color:#000060\">6. <strong>Humans (Anthropochory)<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>How it works<\/strong>: Humans may move seeds intentionally or accidentally (e.g., through trade, transportation, or gardening).<\/li>\n\n\n\n<li><strong>Examples<\/strong>: Planting crops, transporting seeds in bags, or seeds being carried in footwear or clothing.<\/li>\n\n\n\n<li><strong>Advantages<\/strong>: Helps in the spread of cultivated plants and even invasive species.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-large-font-size\"><strong>Summary of Seed Dispersal Agents:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Wind<\/strong>: Disperses lightweight seeds.<\/li>\n\n\n\n<li><strong>Water<\/strong>: Carries buoyant seeds to new locations.<\/li>\n\n\n\n<li><strong>Animals<\/strong>: Includes external and internal dispersal through consumption or attachment.<\/li>\n\n\n\n<li><strong>Gravity<\/strong>: Seeds simply fall from the plant.<\/li>\n\n\n\n<li><strong>Explosions<\/strong>: Seeds are forcefully ejected by the plant.<\/li>\n\n\n\n<li><strong>Humans<\/strong>: Seeds spread through human activities.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color has-large-font-size\" style=\"color:#d90000\"><strong>Let&#8217;s practice!<\/strong><\/p>\n\n\n\n<div class=\"wp-block-columns
