Unit: Plant Growth & Development Advanced Plant Sciences Mr. Dieckhoff
1. ID the parts of a plant cell… • Chloroplast – holds chlorophyll • Plasma Membrane – Controls entrance & exits • Cell Wall – 3 layers • Cytoplasm – Liquid in cell • Vacuole – Store water • Mitochondrion – Respiration • Nucleus - Genetics
**Four elements of the cell structure: A. Cell wall B. Plasma membrane C. Cytoplasma D. Nucleus
Tobacco flower losing pigment because lack of mitochondria proteins
2. What are 2 function of PM? • Control entrance & exit into and out of cell • Relays environmental information about condition
3. What are 3 organelles…… • Mitochondria – Control Chemical Reactions, site of respiration • Plastids – Contain Chloroplasts; contain chromoplasts (red, yellow, brown pigments) • Vacuoles – store water, dissolve minerals
4. What are 3 func. of nucleus.. • Control Physiological Characteristics • Control Appearance of Plant • Passes Characteristics to Offspring
5. What are 2 types tissue…. • Meristem • Permanent
6. What are differences…… Meristem actively divides to form new growth where permanent does not actively divide
7. What are 3 types meristems.. • Apical – plant length • Cambium – plant diameter • Intercalary Zone – stem height
**Cambium Meristem View Video
8. What two types permanent… • Epidermis – outside covering • Vascular System – transportation system of plant • Xylem - Up • Phloem - Down
**Five basic parts of a plant: A. Seeds • B. Roots • C. Stems • D. Leaves • E. Flowers
9. What are three parts mono… • Seed Coat – Protect embryo • Embryo – Miniature plant • Endosperm - Nourishment
10. **Which is found only mono… Endosperm
11. What are 4 parts embryo? • Cotyledon • Epicotyl • Hypocotyl • Radicle
12. **What another term seed leaf Cotyledon
13. What type of Plant…. • Has one leaf – Monocot • Has two leaves - Dicot
**Crown Thick, compressed stem whose leaves and flower buds grow just above ground Example in CCC Greenhouse: fern
14. **What are 3 func. Roots…. • Synthesize hormones for plant growth • Store carbohydrates • Provide aerial support • Anchor plant • Absorb Water and Nutrients
15. What are 5 types roots…. • Taproot • Fibrous • Aerial • Adventitious • Aquatic
16. What is pith? Parenchyma cells
17. What is hyposophylls? Floral bracts – protect buds during development Dogwood
18. ID interior parts of leaf…. • Phloem • Xylem • Cuticle • Upper epidermis • Chloroplast • Lower epidermis • Cuticle • Stomata • Guard Cell • Spongy mesophyll • Palisade mesophyll View Video
