Plants: Presentation Two for Spaced Learning
- 1. PLANTS: A SPACED LEARNING LESSON 2nd Presentation – Fill in the blanks! By: Andrea Kirk
- 3. NONVASCULAR PLANTS Nonvascular: These plants lack ________ _______ to transport water and nutrients. They rely on simple diffusion to move water, and must live in a moist environment. ______________ grow very tall because they lack vascular tissue. Lack true ________, ________, and _________. Some have root-like structures called rhizoids Includes Mosses, ______________, and Hornworts
- 5. NONVASCULAR PLANTS Life Cycle: The __________________ is the dominant generation Does not utilize seeds, but uses wind blown ___________ to disperse the offspring. _________________sperm requires water to reach and fertilize the egg; another reason why they must live in a moist area.
- 8. VASCULAR PLANTS Vascular plants have specialized structures: Roots, stems, and leaves Differentiated tissues: meristematic, ground, vascular, and dermal tissues. Can grow much _____________ than nonvascular plants due to their vascular structures. The life cycle has a dominant _________________ generation, in contrast to the dominant gametophyte in nonvascular plants
- 9. TISSUES Vascular plants have _______________ tissues that perform separate but important functions. Meristematic Tissue: consists of cells that grow and divide repeatedly. ________________ Tissue: these cells form the xylem and phloem that transport water and nutrients Ground Tissue: has cells that are rich in chloroplasts and conducts photosynthesis ________________ Tissue: these cells protect the vascular structures of the plant.
- 10. TISSUES IN VARIOUS PLANT PARTS ???__________ _
- 11. MAIN PLANT PARTS Roots ____________ Leaves All of these parts contain dermal vascular and ground tissues.
- 12. THE ROOTS Functions: Anchoring Absorption __________________ Structure: Root Hairs – increase the surface area for more absorption Zone of Elongation Meristematic Zone – part of the root tip where cells ____________________________to extend the root. Root Cap – _________________ the root tip
- 14. STEM Function: Connects the roots to the leaves and acts as the plumbing for the plant Structure: Xylem: ________ way Transports water and minerals upward Stiff, thick walls Phloem ________ way Transports products of _____________________ and water up and down __________________walls
- 16. STRUCTURE
- 17. LEAVES Function: Capture the sunlight and are the main area of _____________________ for the plant. Structure: Leaf Margins:
- 19. LEAF STRUCTURE Cuticle – waxy and water repellent. Excreted by the epidermis _____________________ - outer layer of cells Palisade Mesophyll – elongated cells that contain a lot of chlorophyll Spongy Mesophyll – Round irregular cells that allow for _______ exchange Stoma – ___________ in the leaves for water and gas movement (more on the bottom of leaf) Guard Cells – “Guard” the stoma to open and close it. Vein – contains the _________ and _________ for the leaf.
- 20. LEAF STRUCTURE
- 22. TYPES OF VASCULAR PLANTS Seed: ________________ Angiosperms _______________: Ferns Whisk ferns Horsetails
- 23. SEED VASCULAR PLANTS Gymnosperms: Ginkgos, Gnetales, cycads, and ____________ “____________ seeds” that are not enclosed in a protective structure. The ovule normally develops on the surface of a scale (cone) or at the tip of a modified leaf. Conifers are the most abundant gymnosperms and include pine trees Life Cycle: The __________________ is the dominant portion of the life cycle.
- 25. SEED VASCULAR PLANTS Gymnosperms:
- 26. SEED VASCULAR PLANTS Angiosperms The ________ _________group of land plants. “________________ plants” - the ovule develops inside a protective ovary. The mature ovary becomes a fruit. Life Cycle: The sporophyte is dominant. ______________ fertilization occurs to produce an endosperm, the food supply, and a zygote.
- 27. SEED VASCULAR PLANTS Angiosperms
- 28. SEED VASCULAR PLANTS Angiosperms Two main divisions of flowering plants. _________________tyledon: Monocots One cotyledon (seed leaf) Flower parts in threes ___________ leaf veins Scattered vascular bundles Dicotyledon: Dicots _________ cotyledons Flower parts in fours and fives Net-like leaf veins Vascular bundles are arranged in a ring.
- 30. SEED VASCULAR PLANTS Seed structure
- 31. SEEDLESS VASCULAR PLANTS Include whisk ferns, ___________, club mosses, and horsetails. Life Cycle: The sporophyte is dominant Use windblown _____________, not seeds, to disperse their offspring. The sperm is __________________ and requires water to reach the egg. These plants are limited to __________________
- 33. SEEDLESS VASCULAR PLANTS ____________ = cluster of sporangia that can be located on the underside of a fern leaf. Sporangia = enclosure of ___________
- 34. SEEDLESS VASCULAR PLANTS: FERN ___________________: An uncurling frond
- 35. BRAIN BREAK Pantomime!! The leader will act out an activity without speaking. The class will mimic the leader’s actions and attempt to guess what activity they are doing The winner is the next leader 10 minutes
