Plants Chapter 8 Unit # 6

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

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

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

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

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

Cuticle

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.

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

Plant Reproduction

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

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

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

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.

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

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

Plants Without Seeds

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

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

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

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

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

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

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

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

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

Seedless Vascular Plants 29. Fern leaves are called FRONDS!

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

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.
