1. ID the parts of a plant cellChloroplast holds chlorophyllPlasma Membrane Controls entrance & exitsCell Wall 3 layersCytoplasm Liquid in cellVacuole Store waterMitochondrion RespirationNucleus - Genetics

**Four elements of the cell structure:

A. Cell wall B. Plasma membrane C. Cytoplasma D. Nucleus

Cell Wall Structure

Too little water in vacuole..

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 organellesMitochondria 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 differencesMeristem 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 MeristemView Video

Intercalary Zone Meristem

8. What two types permanentEpidermis outside covering

Vascular System transportation system of plantXylem - UpPhloem - Down

**Five basic parts of a plant:A. Seeds B. Roots C. Stems D. Leaves E. Flowers

9. What are three parts monoSeed Coat Protect embryoEmbryo Miniature plantEndosperm - Nourishment

10. **Which is found only monoEndosperm

11. What are 4 parts embryo?Cotyledon

Epicotyl

Hypocotyl

Radicle

12. **What another term seed leafCotyledon

13. What type of Plant.Has one leaf Monocot

Has two leaves - Dicot

**Stems.

Stolon

**CrownThick, compressed stem whose leaves and flower buds grow just above ground

Example in CCC Greenhouse: fern

Rhizome

14. **What are 3 func. Roots.Synthesize hormones for plant growth

Store carbohydrates

Provide aerial support

Anchor plant

Absorb Water and Nutrients

Application of Rooting Hormone

Dont cut alfalfa in October

Wait Until November

Or Next Year will Look Like.

15. What are 5 types roots.Taproot

Fibrous

Aerial

Adventitious

Aquatic

Adventitious Roots

Tap Root

Aerial Roots

Aquatic Roots

16. What is pith?Parenchyma cells

17. What is hyposophylls?Floral bracts protect buds during developmentDogwood

18. ID interior parts of leaf.PhloemXylemCuticleUpper epidermisChloroplastLower epidermisCuticleStomataGuard CellSpongy mesophyllPalisade mesophyllView Video

**The 3 structures of a leaf:

A. Epidermis B. Mesophyll layer C. Vascular bundles

View Guard Cells & Stomata of Wandering Jew

19. What are 2 func. Leaves?Manufacture food through photosynthesis

Protect vegetative and floral buds

20. What do not have stomata?Submerged plants (aquatic)

21. What are char. xeromorphicThick-walled epidermis covered with waxy cuticle (holds water in stems)

22. What type modified leaf.Sac

23. What is corolla.Petals protect stamen and pistil in bud stage; attract pollinating insects

24. Gynoecium refers toFemale reproductive parts

25. What do head, spike, umbelTypes of inflorescence flowers

26. What are 3 char perfectContain male and female parts

All four parts of flower are present

Usually self-pollinating

**KNOW

**Monoecious (different places) vs. Dioecious (same place)

Cross Pollinating

Self Pollinating
