Part 1:

1. There are 2 types of pollination, name and explain the differences between the 2 types.

2. There are 2 ways in which a plant can get the pollen from another plant, name these two ways.

3. Find a picture of each type of plant you named in question 2. 

Part 2:

1. petal - forms the flower together with others of its kind, can be brightly colored

2. stamen - the name for all the male parts together

3. anther - produces pollen

4. filament -  supports the anther 

5. sepal - little green leaves that covered the flower when it was a bud

6. nectary - produces nectar to attract insects

7. stigma - the place where the pollen is supposed to land

8. style - connects the stigma of the ovary 

9. ovary - produces ovules

10. carpel - the name for all the female parts together

11. receptacle - forms the base of the flower

ovule - get fertilized and becomes seeds

Part 3:

When a farmer plants kiwi’s he must be careful to plant an equal amount of male and female trees to get fruits.

1. What type of flowers will these trees have, perfect or imperfect? Explain your answer.

2. Will all trees have fruits? Explain your answer

Today:

- Fertilization

- Dipersal

FERTILIZATION

• THE POLLEN LANDS ON THE STIGMA
• THE POLLEN GOES DOWN THROUGH THE STYLE
• THE POLLEN GRAIN MELTS TOGETHER WITH THE OVULE IN THE OVARY TO FORM A SEED.

DISPERSAL

• THE MOVEMENT OF SEEDS AND FRUITS AWAY FROM THE PARENTS PLANT.
• THIS GIVES THE JUVENILE PLANTS A BETTER CHANCE OF SURVIVAL.

TYPES OF DISPERSAL:

• human
• wind
• water
• animal
• self

GERMINATION:

• THE MOMENT THE SEED START TO GROW.
• THE RADICLE GROWS FIRST
• THEN THE PLUMULE GROWS.
