Life Cycle of a Flowering Plant Vocabulary to Know:1. Germinating: when a seedling comes up.2. Pollinating: when pollen goes from an anther
(male) to a pistil (female).3. Stamen: The lengthy stem holding the anther out
for pollinators to reach.4. Pistil: the part of the flower that holds the ovary.5. Ovary: where the eggs are contained in a flower.6. Pollen: the seed that fertilizes the egg in a flower.7. Seedling: the first sprout that germinates from a
seed.

Life Cycle of a Flowering Plant Pollination: 3 Methods-1. Self-pollination: plants can use their own
pollen to fertilize their flowers.2. Natural pollination: the wind or animals
transfer pollen from anthers to pistils3. Cross-pollination: plants of one kind can
pollinate plants of another kind.

Life Cycle of a Flowering Plant Seeds have
three parts:◦ Embryo◦ Food
(cotyledon)◦ Seed coat
Once seeds find water, space and sun, they germinate.

Life Cycle of a Flowering Plant Create your own Mini Book about the life cycle
of a flowering plant using the Mini Book 2 template worksheet. Each page should contain a picture of the stage in the life cycle and a label.
Number your pages. Cut out your pages. On the back of each page write one sentence
about what happens in that stage. Staple your Mini Book together on the left hand
side to make a book.

Parts of a Flower Work in your seed groups and use the
Internet to find pictures of the flower that your plant produces.
On a sheet of drawing paper, make a careful drawing of your plant’s flower. Notice the colors and shapes of the flower.
On your drawing, labels the parts of the flower, identifying the parts that match the picture of a flower in our notes.
Color your picture so the flower is the correct color for your plant.
