Let’s make a list of what plants need: Water Sun Soil Nutrients/Food

What do plants need?

Need Indoors Outdoors

Water Tap Water Rain/Hose

Light Lamps/Bulbs/Windows Sun

Soil Potting soil Dirt/Ground

Nutrients/Food Fertilizer Soil/Bugs/Animals

Where do these needs come from?

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

Germinating

Pollinating

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.

Plant CellsVocabulary to Know:1. Cell Wall: the cellulose wall

surrounding the cell.2. Cell Membrane: 3. Mitochondria:4. Vacuole:5. Nucleus:6. Cytoplasm:7. Choloroplast:

Plant Cells

Cell MembraneThin skin on the outside of a cell that allows nutrients and waste to pass in and out of the cell.

Plant CellsMitochondriaCreate the energy used by the cell every day. “Powerhouse of the cell”

Plant CellsCell Wall

Firm structure and support for the cell.

Protects the cell membrane.

Plant CellsVacuole

Contains water or waste products of the cell.Storage closet for the cell.

Plant CellsNucleus

The “brain” of the cell.Contains the DNA and controls everything in the cell.

Plant CellsChloroplastsContain chlorophyll, conduct photosynthesis, store food for the cell.

Plant CellsEndoplasmic Reticulum

The “stomach” of the cell, digests carbs and fats. Also, the “post office” of the cell, packaging things up and shipping them out!

Plant CellsRibosome

Make proteins for the cell to use.

Plant CellsCytoplasmThe “jelly” in which the other organelles exist and do their things!
