Unit # 6

2. 1. Plants are part of the Kingdom Plantae.
What are Plants?
1. Plants are part of the Kingdom Plantae.

3. What are Plants?
2. Plants are considered autotrophs because they use photosynthesis to make their own food.

4. What are Plants?
3. You do not need a microscope to see plants because they are multicellular.
Made up of multiple cells

5. What are Plants? 4. In order to survive on land:
Must have way to obtain water and other nutrients from surroundings
Retain water
Transport materials in their
bodies
Support their bodies
Reproduce

6. What are Plants?
5. Cuticle: Waxy, waterproof layer that covers the leaves of plants 6. Helps prevent water loss

7. Cuticle

8. What are Plants?
7. Larger plants have transport tissue called vascular tissue.
8. Vascular Tissue: System of tubelike structures inside a plant which water, minerals and food move.

9. What are Plants?
9. Cell walls and vascular tissue add strength to the bodies of large
plants.
10. All plants undergo sexual reproduction.

10. Plant Reproduction

11. 11. All Plants… Nearly all are autotrophs Eukaryotes Multicellular
Have cells surrounded by cell walls

13. Draw a picture of a plant cell here with the following labeled:
Cell Wall
Chloroplasts
Cytoplasm
Vacuole
Cell membrane
Nucleus
12. Parts of a Plant Cell

14. 13. Scientists informally group plants into 2 major groups
14. Vascular Plants
True vascular tissue
Suited to drier areas
Moves materials quickly and efficiently
Can grow tall
14. Nonvascular Plants
Lack vascular tissue
Low Growing
Do not have roots
Thin cell walls

15. Studying Plants
15. One way scientists study the origin of plants is with fossils.
16. Scientists can infer that green algae are the ancient ancestors of today’s plants.

16. Plant Reproduction
17. Plants produce spores during the sporophyte stage and produce sex cells during the gametophyte stage.

17. Plant Reproduction FALSE!
18. TRUE OR FALSE? The sporophyte of a plant looks the same as the gametophyte.

18. Plants Without Seeds

19. Plants Without Seeds 19. Two characteristics of nonvascular plants:
Low-growing
Live in moist areas
Absorb nutrients
directly from environment
Seedless
Non-vascular tissue

20. FALSE! Plants Without Seeds
20. True or False: Nonvascular plants can become very large and tall because of their support system.
FALSE!

21. Plants Without Seeds
21. Nonvascular plants get water by absorbing water directly from their surroundings.
OSMOSIS!

22. TRUE! Plants Without Seeds
22. TRUE OR FALSE: Nonvascular plants must have water to let the sperm cells swim to the egg cell.
TRUE!

23. Plants Without Seeds
23. Label the gametophyte and the sporophyte in the diagram of the moss.

24. Plants Without Seeds
24. The thin, root-like structures that anchor moss and absorb water and nutrients from the soil are called rhizoids.

25. Plants Without Seeds
25. Liverworts are found growing:
Moist Rocks
Soil along the side of streams

26. Seedless Vascular Plants
26. Characteristics of ferns, club mosses and horsetails:
True Vascular tissue
Do not produce seeds (make spores)
27. C and D are TRUE!
Vascular tissue transports water
and food
Vascular tissue gives strength
and stability

27. Seedless Vascular Plants
28. Fern and club mosses must live in moist surrounding in order for them to reproduce
Release spores and need to get egg and sperm cells to join

28. Seedless Vascular Plants
29. Fern leaves are called FRONDS!

29. Seedless Vascular Plants
30. The cuticle on the upper surface of fronds is used to prevent water loss.

30. Seedless Vascular Plants
31. Horsetails and club mosses…
B: Club mosses grow in moist woodlands and near streams
D: Horsetail stems contain silica, a gritty substance also found in sane.

31. Horsetail

32. Club Moss
