1. Kingdom Plantae
thousand species
Huge diversity

2. What do we know already?

3. Five characteristics of plants?
1.) Lack mobility
2.) Eukaryotic
3.) Numerous cell organelles
4.) Cellulose cell walls
5.) Photosynthesis

4. Evolution • Diversity within a population promotes long-term survival
– Organisms that can adapt to new surroundings and changes in the environment will survive.
Earth first colonized by fungi & plants that came from the water
– The move to drier conditions necessitated the evolution of structures and tissues for support outside of the water

5. Division of angiosperms
Monocots
Have 1 seed leaf
Parallel veins on leaves
3 part symmetry of flowers
Fibrous roots
Ex: lilies, onions, corn, grass, wheat
Dicots
• have 2 seed leaves
• Network of veins on
leaves
• 4-5 part symmetry of flowers
• Taproots
• Ex: maple trees,
peas, cabbage, cacti

8. General Structures Roots Absorb water and minerals Anchor the plant to
the substrate (ground)
Stems
Support plant
Transport water
through the xylem
Transport nutrients
through the phloem

9. Leaves
Photosynthetic organs of the plant
Have stomata: pores within the leaf that open to let CO2 in and O2 out
Cuticle: waxy covering on leaves that prevents water loss

10. Flowers
Reproductive organs of the plant
Flowers are usually both male and female
Male part: “stamen”
Female part: “pistil”
“Stigma”
“Ovary”

11. Reproduction Pollen is produced by the stamen
Pollen moves away from the plant via the wind or other pollinators (birds, insects)
The pollen lands on the pistil of another plant and fertilizes the eggs within the ovary
The flower petals fall off, the ovary becomes a fruit with seeds inside
Fruits are dispersed in a variety of ways (wind, animals, people)
Fruits are not always edible! (e.g. dandelion fluff)

14. Pick an angiosperm that you know
Draw and label the lifecycle of angiosperm in steps. Make a comic or story out of it.
Some key words to use – Germinate, monocot, dicot, cotyledon, radicle, coleoptile, seed coat, embryo, endosperm, root, stamen, pistil, stigma, ovary, pollinate, fruit, flower etc.
Be creative and have fun.
