Transcript of Unit: Plant Growth & Development Advanced Plant Sciences Mr. Dieckhoff.
1. ID the parts of a plant cell…
A. Chloroplast – holds chlorophyll
B. Plasma Membrane – Controls entrance & exits
C. Cell Wall – 3 layers
D. Cytoplasm – Liquid in cell
E. Vacuole – Store water
F. Mitochondrion – Respiration
G. Nucleus - Genetics
2. What are 2 function of PM?
a) Control entrance & exit into and out of cell
b) Relays environmental information about condition
3. What are 3 organelles……
1) Mitochondria – Control Chemical Reactions, site of respiration
2) Plastids – Contain Chloroplasts; contain chromoplasts (red, yellow, brown pigments)
3) Vacuoles – store water, dissolve minerals
4. What are 3 func. of nucleus..
A. Control Physiological Characteristics
B. Control Appearance of Plant
C. Passes Characteristics to Offspring
6. What are differences……
Meristem actively divides to form new growth where permanent does not actively divide
7. What are 3 types meristems..
1) Apical – plant length
2) Cambium – plant diameter
3) Intercalary Zone – stem height
**Cambium Meristem

8. What two types permanent…
1) Epidermis – outside covering
2) Vascular System – transportation system of plant
a) Xylem - Up
b) Phloem - Down
**Five basic parts of a plant:
A. Seeds
• B. Roots
• C. Stems
• D. Leaves
• E. Flowers
9. What are three parts mono…
1) Seed Coat – Protect embryo
2) Embryo – Miniature plant
3) Endosperm - Nourishment
**Crown
Thick, compressed stem whose leaves and flower buds grow just above ground
Example in CCC Greenhouse: fern
14. **What are 3 func. Roots….
A) Synthesize hormones for plant growth
B) Store carbohydrates
C) Provide aerial support
D) Anchor plant
E) Absorb Water and Nutrients

19. What are 2 func. Leaves?
A) Manufacture food through photosynthesis
B) Protect vegetative and floral buds
21. What are char. xeromorphic
Thick-walled epidermis covered with waxy cuticle (holds water in stems)
26. What are 3 char perfect…
A) Contain male and female parts
B) All four parts of flower are present
C) Usually self-pollinating
