Oh say can you seed?? The wonderful world of flowers, fruits and seed Special Flower Terms Solitary Single flowers, such as a tulip - • Inflorescence - A group of flowers clustered together such as a geranium or gladiolus Special Flower Terms Peduncle - The stem of flower Pedicels - The stem – like structures bearing the individual flowers in a inflorescence Types of Inflorescences Indeterminate A. - Flowers from the bottom open first Flowers from the outside open first Up and in 1. raceme - long inflorescence with stalked flowers 2. corymb - flat-topped or rounded inflor. with lower pedicels longer than upper ones Types of Inflorescences 3. Panicle - branched, raceme-like inflor. 4. Spike - long inflor. with sessile flowers - a spadix is a kind of spike - another kind of spike is the catkin Type of Inflorescence B. Determinate - Flowers open from the top down - Flowers open from the inside out - Down and out Types of Inflorescence C. Inflor. That Can Be Either 1. Umbel - all pedicels originated from the same point 2. Head - sessile flowers originating from the same point Types of Fruit A. Multiple Fruits – formed by the development of several flowers Ex: pineapple, mulberry Types of Fruit B. Aggregate – formed by the development of several ovaries of one flower Examples: raspberry, blackberry Types of Fruit C. Simple 1. Berry - the fruit is fleshy throughout Examples: tomato, blueberry 2. Pepo – a specialized berry with a thick, hard rind at maturity Examples: watermelon, honeydew melon, pumpkin, squash Types of Fruit 3. Hesperidium – a specialized berry with a leathery rind and very juicy, distinct segments Example: orange, lime, grapefruit 4. Drupe – a fleshy, with usually one-seeded enclosed in a stony structure with a thin outer skin Example: cherry, plum, peach Types of Fruit Pome – fleshy fruit with many seed Examples: apple, pear “Oh say can you seed?” Seed Develops after an ovule inside the ovary has been fertilized How does fertilization work? Pollen from the anther is carried by wind, insect, humans, etc. Lands on the sticky surface of the stigma A pollen tube is formed and grows down the style Pollen tube attaches to the ovule inside the ovary “Oh say can you seed?” Parts of the seed Embryo – the baby plant! Endosperm – food for the baby plant Seed coat – protective covering Cotyledons – the first leaf or leaves to appear once the seed germinates Where we get the terms “monocot” and “dicot”
