2 Plants Why are plants important to you? The_Plant_Life_Cycle_and_Us.mov Plants Are living (Biotic) They grow Reproduce Respond to their environment

3 Flowering Plants Make up 90% of all plants They vary greatly in appearance and size. Fit in your hand Climb in

4 Basic parts of a flowering plant The_Parts_of_a_Flowering_Plant. mov The_Parts_of_a_Flowering_Plant. mov Flower Stem Leaves Roots

5 The role of roots Absorb water Absorb nutrients Provide an anchor Store food

6 Types of root systems Tap root –Goes deep to find water. –Provides a strong anchor in the wind. Fibrous –Fan out to find water –Roots are shallow. –the plant can easily be blown over in high winds.

7 Root Close Up Root cap Root hair

8 Stem supports the plant above the ground transports water and nutrients Xylem - transports it up the plant Phloem - flows it down the plant

9 Leaves Blade - makes up the broad part of the leaf. Veins - transport nutrients and water. Petiole - connects the stem and the leaf.

10 Leaves are Busy Plants produce their own food through a process called photosynthesis. light and carbon dioxide are taken in. oxygen is released.

11 Flower The flowers are responsible for reproduction.

12 The Parts of a Flower A bud is a developing flower Sepal protect the bud

13 The Parts of a Flower Petals – usually colorful Sepal – protects the bud; sometimes they fall off after the flower is formed

14 The Parts of a Flower Pistil – female part Stigma – Sticky so the pollen will stick to it. Style – Tube like structure for support Ovary – Where the pollen goes down. It becomes the fruit Ovule – Where the seed develops

15 The Parts of a Flower Stamen – male part Anther – Carries the pollen Filament – Supports the anther

16 Two Types of Flowers Perfect – has both male and female parts on the same flower. Imperfect – have only the male or only the female parts on the same flower.

17 Pollination 1)The petals attract birds and insects by their color or smell. 2)The bird or insect moves the pollen from the anther to the stigma.

18 Spreading the Seeds Birds and animals eat the fruit, which causes the seeds to be dispersed. Wind can also disperse seeds.

19 Protection Plants have developed several different forms of protection: »Thorns »Poison
