Seeds What are seeds?

Basic Parts of Seeds 1. Embryo n 2. Food Supply n 3. Ovary wall or seed coat n

Germination Needed for Germ n 1. Temperature n 2. Moisture n 3. Air n 4. Light or absence of it n

Germination Process n 1. Seed absorbs water n 2. Seeds proteins activated n 3. Radicle (root) emerges n

Germination 4. Plumule or embryonic shoot emerges n 5. Leaves form and food production begins n

Monocot Seeds 1. Seed coatprotection n 2. Endosperm- a source of energy n 3. Embryo-miniature plant that has n

Monocot Seeds n 3. Embryo: u. Epicotyle-shoot above cotyledon u. Hypocotyl-part of stem below the cotyledon u. Radicle- primary

Dicot Seeds n n 1. Seed Coatprotection 2. Embryo miniature plant

Dicot Seeds n 2. Embryou 2 cotyledons-seed leaves u. Epicotyl-true leaves u. Hypocotyl-first stem, pulls seed upward u. Radicle-forms roots

Monocot Germination 1. Seed swells n 2. Radicle grows down n 3. First internode and epicotyl grows upward n

Monocot Germination 4. New leaves form and food production starts n 5. New root system develops n 6. Temporary root system ceases to n

Dicot Germination 1. Seed swells n 2. Radicle grows down n 3. Hypocotyl forms arch that breaks soil surface n

Dicot Germination 4. Hypocotyl reaches light and straightens up n 5. Cotyledons turn green and make food n 6. As new leaves develop, cotyledons n
