  1. Plant Life Cycles

  2. How do plants grow? • Seeds-structures that can grow into new plants • Embryo-a young plant inside a seed that is ready to grow • Seeds store food to help the embryo survive and have a tough covering to protect the embryo • Germinate-begin to grow • Seedling-a small plant • http://www.bbc.co.uk/schools/scienceclips/ages/5_6/growing_plants_fs.shtml

  3. How do plants make seeds? • Flower-the plant structure that makes seeds • Flowering plants-plants that use flowers to make seeds • Seeds have two parts: pollen-male part and egg-female part • Ways that the pollen and egg get together: wind, animals, or insects • Pollination-the movement of pollen to the egg • Fruit-the structure that holds the seeds • Seeds travel to the soil by wind, falling to the ground, or animals (by being buried, sticking to fur, or as waste) • http://www.teachersdomain.org/resource/evscps.sci.life.seedint/

  4. What is the life cycle of some plants? • Life cycle-the stages of an organism’s life • Plant life cycle-how a plant germinates, grows, and reproduces • Conifers-plants that reproduce using cones • Cones-plant structures that make seeds • Two types of plants-Flowering plants and Conifers • http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/index.htm

  5. How do plants grow without seeds? • Spores-can fall to the ground and make a new plant • Spores-cannot store food • Fern is a type of plant that makes spores • Potatoes create new plants through “eyes” or white spots • Bulb-underground stem (onion is one type)
