3. Mav Mark
What is a characteristic of a plant that is useful when making paper?
Why is it important to press and dry the newly made paper?
The first known paper was papyrus. Was this a conifer? Explain.

4. Mav Mark What is a gymnosperm?
What are four examples of gymnosperms and where are they found?

5. Mav Mark
Describe the Life Cycle of the Gymnosperm

6. Mav Mark What is the difference between a gymnosperm and an angiosperm
What does gymno- mean?
What does angio- mean?
What does –sperm mean?

7. Mav Mark Give three characteristics of Monocots
Give three characteristics of Dicots

8. 1. A gymnosperm
Is a seed plant that produces “naked” seeds (they are not inside a fruit)
Usually has needle-like or scale-like leaves and a deep growing root system.

10. 2. Different types of gymnosperms are
Cycads are usually found in tropical areas
Conifers are cone-bearing plants; the largest gymnosperm group
Ginkgoes – today there is only one species left; Ginkgo biloba
Gnetophytes live in hot deserts and tropical rainforests

11. Gingko leaf-unique shape

12. cycads
conifers

13. Ginkgoes
gnetophytes

15. 3. Most gymnosperms reproduce with cones
Cones are covered with scales
There are usually two different cones:
Male cones produce pollen
Female cones contain an ovule

18. Pine Cones
Male Cone
Female Cone

19. 4. Pollination is
A transfer of pollen from the male reproductive structure to the female
After pollination, the egg is fertilized and seeds are dispersed by the wind

20. 5. Gymnosperms provide many useful products
Paper
Lumber used for building homes
Rayon fibers in clothes
Cellophane wrappers on food
Turpentine in paint
Rosin

22. Angiosperms

23. 1. Angiosperms are Flowering plants that produce
Flowers
Seeds inside fruits
Found everywhere on Earth

24. 2. The flower is the reproductive structure of the plant
Come in all shapes and sizes:
Complete flower
Incomplete flower
Flowers include:
Sepals and petals
Stamens
Pistils

25. 3. The Sepals and Petals
Sepals are leaf-like structures that protect the flower when it is a bud
Petals are colorful leaf-like structures
Petals vary from plant to plant. In fact, not all flowers have petals!

27. 4. Stamens Stamens are the male reproductive parts
Filament (thin stalk)
Anther (produces pollen; sits on top of filament)

28. 5. Pistils Pistils are the female reproductive parts
Stigma (sticky tip)
Style (a slender tube that connects stigma and ovary)
Ovary (contains the ovule which has eggs that become seeds)

30. 6. Pollinators
Insects, birds, and bats are attracted to a flower’s color, shape, or smell.
They help carry pollen from one flower to another

31. 7. Reproduction in angiosperms
Pollen falls on the stigma from the anther
Sperm from the pollen fertilized the egg in the ovule
Seed develops
Ovary swells and grows around the seed as a fruit

32. 8. Types of angiosperms Two major groups are monocots and dicots
Have one seed leaf
Long slender leaves; parallel veins
Flowers have 3 petals or multiples of 3
Example: corn, wheat, rice
Dicots
Have two seed leaves
Leaves are wide with branched veins
Flowers have 4 or 5 petals or multiples of 4 or 5
Example: roses, violets, dandelions

34. 9. Angiosperms in Everyday Life
Food
Clothing
Medicine
Furniture
