Do First: Answer the following 6 questions in your DFAD

Plant Sex: It’s all around us…

■ When you eat fruit, you are eating a plant ovary.

■ The pollen that makes you sneeze is full of plant sperm.

■ When you give someone flowers, they are full of plant reproductive structures.

■ Bees buzz around transferring sperm from one plant to another so they can reproduce.

reproductivestructures of plants

Attract pollinators (bees, insects, etc.)

Male Flower Parts

Stamens■Made of

filament and anther.

Anther and FilamentParts of the plant

that makes pollenon the top part of the stamen is called the anther.

The filament hold up and supportsthe anther.

CFU – If pollen is plant sperm cells and they are made in the anther, what organ in the human body system relates to the production of male gametes?

Pollen

■Contains sperm cells

Female Flower Parts

PistilThe pistil is

made of the stigma and the style.

The Stigma and Style

■ The sticky top of the pistil where pollen is collected

Style■ Style holds up and

supports the stigma

The Ovary

■ Produces the eggcells that will develop into seeds once they have been fertilized

Non-reproductive parts

Sepals■ Protect the

flower before it opens.

sepal

PetalsAttract

pollinating insects with their bright color and attractive scent.

Pollination

■ Plant flowers attract insects that eat the pollen or nectar the plant produces

PollinationAs the insect

probes for nectar, its body rubs against the stamens.

Pollen gets stuck on the insect.

Pollination■ When the insect

visits another flower of the same type, the pollen will stick to the stigma.

Fertilization■ The pollen travels to the

ovary so the sperm can fertilize an egg cell

■ The fertilized egg turns into a seed, the ovary develops into a fruit.

Seed Dispersal

The seeds are dispersed; some by animals, some by the wind, some by explosion and some by water.

Germination

■ If the seed lands in a suitable place, it will develop, and grow into a new plant.

■ Then the cycle starts all over again.

CFU #1: Which two structures are not reproductive?

1.Pistil and petal2.Anther and stamen3.Stigma and sepals4.Sepals and petals

Independent Practice■ Answer questions all question starting at Independent

Practice ■ Work must be done silently and independently. ■ No Talking. ■ If you have a question or request raise a silent hand

and be patient. ■ For independent practice, today we will be working

silently and independently for 6 minutes.

Group Practice■ Review the questions answered during Independent practice.

Go over each question. Each table member should explain why they selected their answer.

■ Work must be done at a level ONE volume, which means I should not be able to hear you from my desk.

■ Remain in your seat and only talk to people at your table.■ Make sure to keep conversations on topic. ■ If you have a question or request raise a silent hand and be

patient. ■ For group practice, today we will be working for 10 minutes.
