Topic: Reproduction Aim: Describe the structure of a flower and how it uses sexual reproduction. Do Now: Take out your HW. HW: Earth Day Poster due Friday! Castle Learning – Reproduction Due Tuesday, April 19 th

1.Identify the process that produces the zygote. 2.Identify the structure after the zygote. 3.What type of cell division occurs after the zygote? 4.Identify the structure in the diagram that labeled “embryo.” 5.Identify the process that occurs after the “embryo.” 6.Where would the blastula go in the diagram? fertilization morula mitosis gastrula differentiation After the morula

1. How do non- flowering plants reproduce? Grow from spores instead of seeds

2. Why are petals brightly colored? To attract insects to pick up pollen from the flower and carry it to the next flower

PETALS

4. Identify 2 ways flowers can be pollinated. By insects Wind

5. Identify the structures that protect the flower when it is still a bud. Sepals

6. Describe the appearance (COLOR) of sepals. Usually green or brown

PETALS SEPALS

8. Identify the male parts of a flower and the two parts its consists of. Stamen Anther and filament

9. Identify the male reproductive structure that produces pollen. Anther Pollen: male gamete

PETALS SEPALS ANTHER

How many sperm nuclei are present in a pollen grain?

11. Identify the part of the male reproductive structure that holds up the anther. Filament

PETALS SEPALS ANTHER FILAMENT

13. Identify the FEMALE part of the flower and the THRER parts it consists of. Pistil Stigma, style and ovary

14. Identify the female reproductive structure that pollen grains stick to. Stigma

PETALS STIGMA ANTHER FILAMENT SEPALS

16. Identify the female reproductive structure that holds up the stigma. Style

PETALS STIGMA ANTHER FILAMENT SEPALS STYLE

18. Identify the female reproductive structure that contains the OVULES. Ovary

PETALS STIGMA ANTHER FILAMENT SEPALS STYLE OVARY

20. Identify what is found in the ovules. Eggs

PETALS STIGMA ANTHER FILAMENT SEPALS STYLE OVARY OVULES

22. Describe what occurs during pollination. When the flower is pollinated, the POLLEN sticks to the STIGMA.

23. Describe what happens once pollination occurs. Pollen tubes form down the style from pollen grains –allow pollen to travel down the style and into ovary

Identify the labeled structures in the diagram. A – B – C – D – E – F - B C D E A F Pollen Stigma Pollen tube Style Ovary Egg

24. Describe the 2 events that occur once fertilization occurs. After fertilization occurs, ovules become SEEDS and the ovary turns into the FRUIT.

Cross pollination or self pollination?

Let’s review: 1.Identify the male part of the flower. 2.Identify the female part of the flower. 3.Where is pollen produced? 4.Where are eggs produced? 5.Identify the structure pollen stick to. 6.Identify the process in which pollen sticks to the stigma. 7.How are pollinators attracted to flowers? 8.How else can a flower be pollinated? 9.Identify the structure that forms in the style to bring pollen to the eggs. 10.What happens to the ovules and ovary once the eggs are fertilized? Stamen Pistil Anther Ovules Stigma Pollination Petals Wind Pollen tube Ovary turns into the fruit. Ovules turns into the seeds.

The part of the pistil which contains the pollen tube is the (1)stigma (2)style (3)ovary (4)ovule

The transfer of pollen between the anther and the stigma in any flowering plant or plants is called (1)fertilization (2)pollination (3)photosynthesis (4)transpiration

The sex cells in a flowering plant are located in the (1) sepals and petals (2) stigma and nectar (3) fruit and seed (4) stamens and pistil

In order to reach an ovule, a ___________ grows through the style and into the ovary. (1)sepal (2) fruit (3) pollen tube (4) seed

The egg cell of a flowering plant develops in the (1) pollen grain (2) ovule (3) stigma (4) fruit

The sperm of flowering plants is contained in the (1) ovule (2) pollen grains (3) style (4) stigma

The entire female reproductive organ in flowering plants is called the (1)pistil (2)stamen (3)stigma (4)sepals

The sticky top of the pistil is called the (1)style (2)anther (3)stigma (4)filament

Which statement below is true? (1)Nymphs after emerging from eggs look like adult insects. (2)Larva after emerging from eggs look like adult insects. (3)Nymphs will develop inside pupa before emerging as adults.

At what stage of development is the insect encased in a protective cocoon? (1)Larva (2)Nymph (3)Pupa (4)Egg

At what stage of development do insects appear work-like? (1)Larva (2)Nymph (3)Pupa (4)Egg

Identify the process occurring in the diagram below. Support your answer.
