- 1. RPSC-GRADE -1 SCHOOL LECTURER BIOLOGY- LECT-#2 TOPIC –Classification of plants UDGAM CLASSES LIKE AND SUBSCRIBE CHANNEL
- 2. The Plant Kingdom 4 This kingdom has organisms that are multi- cellular, have cell walls and chlorophyll, produce their own food, and don’t physically move from one place to anotherz.
- 3. The Plant Kingdom 4 Vascular 4 Non-Vascular 4 Photosynthesis 4 Plant Cell 4 Parts of a Flower 4 SOL Released Test Items
- 4. Plant Classification Non-flowering Plants Flowering Spore- bearing Naked seeds No roots with roots Mosses Ferns Gymnosperms 1 seed- leaf 2 seed- leaves Monocots Dicots
- 6. . 3 groups Ferns Mosses Gymnosperms Non - flowering Plants Do NOT produce flowers
- 7. A plant can be divided into 3 parts
- 10. .No true roots, No vascular tissues (no transport) Characteristics of Mosses .Simple stems & leaves .Have rhizoids for anchorage .Spores from capsules (wind-dispersal) .Damp terrestrial land .Simplest plants
- 12. underground stem root A leaf (finely divided into small parts)
- 14. .roots, feathery leaves & underground stems Characteristics of Ferns .have vascular tissues (transport & support) .Damp & shady places .Spore-producing organ on the underside of leaves (reproduction)
- 17. Male cones (in clusters) Female cones (scattered)
- 18. .roots, woody stems Characteristics of Gymnosperms .needle-shaped leaves .tall evergreen trees .cones with reproductive structures .dry places .vascular tissues (transport) .naked seeds in female cones
- 19. . 2 groups Monocotyledons Dicotyledons Flowering Plants . roots, stems, leaves . vascular tissues (transport) . flowers, fruits (contain seeds)
- 21. . one seed-leaf Characteristics of Monocotyledons leaves have parallel veins . herbaceous plants . e.g. grass, maize
- 23. . two seed-leaves Characteristics of Dicotyledons . leaves have veins in network . e.g. trees, sunflower, rose
- 24. Non-Vascular plants that do not have tubes to carry water up the plant or tubes to carry food made in the leaves down the plant Examples: – mosses – liverworts – ferns – hornworts
- 25. Non-Vascular Spore: the reproductive cell of a nonvascular plant SPORES!
- 30. Vascular Plants that have tubes to carry water up and food down the plant Examples: – American dogwood tree – roses – grass
- 32. Vascular Roses
- 33. Vascular Grass
- 34. Parts of a Flower Male Parts Female Parts
- 35. Parts of a Flower Male Parts Female Parts The stamen consists of two parts: the anther and the fi The filament holds the anther. The anther produces and carries the pollen.
- 36. Parts of a Flower Male Parts Female Parts The pistil consists of three parts: the stigma, style, and The stigma is the sticky part that traps and holds the p The style is the tube-like structure that holds up the sti The ovary and the ovule are at the bottom of the style.
- 37. Parts of a Flower Male Parts Female Parts The petals attract pollinators. (bees, hummingbirds, butterflies, for example)
- 38. Parts of a Flower Male Parts Female Parts The sepals are the green petal-like parts at the base of the flower. Sepals help protect the developing bud.
- 39. Plant Cell nucleus cell wall cell membrane vacuoles chloroplasts cytoplasm
- 40. Test Items
- 103. KEY CONCEPT Plants can be classified into nine phyla/divisions.
- 104. Land plants are classified by the presence or absence of vascular tissue and how they reproduce (with or without seeds) “Vascular” – People: relating to vessels, especially those that carry blood. – Plants: relating to plant tissues that conduct water, sap, and nutrients.
- 105. Vascular Plants vs. Nonvascular Plants Vascular Transport System – Leaves – True roots – Xylem – Phloem – Stems Can grow tall Live in dry areas Nonvascular No Transport System – No roots (rhizoids) Grow close to the ground to absorb water and nutrients Live in moist areas *Complete Venn Diagram in notes
