Chapter 1 Plant Cells

1. ID the parts of a plant cell… v Chloroplast – holds chlorophyll v Plasma Membrane – Controls entrance & exits v Cell Wall – 3 layers v Vacuole – Store water v Mitochondrion – Respiration v Nucleus - Genetics

Chapter 2 Plant Tissue

5. What are 2 types tissue…. 1) Meristem 2) Permanent

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

Intercalary Zone 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

Chapter 3 Seeds & Germination

Monocots vs. Dicots • https: //www. youtube. com/watch? v =g. I 2 Rxz. AT-ww

Cotyledon • First leaves packed full of nutrients

Parts of a Monocot Seed

Parts of a Dicot Seed

Which is found only in monocots Endosperm

4 parts of the embryo 1) Cotyledon 2) Epicotyl – “stem” 3) Hypocotyl – “growing point” 4) Radicle – “root”

Legumes • Dicot plants with pods that fix their own nitrogen

Steps of Germination 1) Seed absorbs water 2) Seed coat breaks open 3) Radicle Emerges & forms roots 4) Epicotyl breaks through soil 5) Cotyledon(s) open 6) Leaves form & photosynthesis starts

Chapter 4 Roots

Don’t cut alfalfa in October

Wait Until November

Or Next Year will Look Like….

15. What are 5 types roots…. A) Taproot B) Fibrous C) Aerial D) Adventitious E) Aquatic

Adventitious Roots

Chapter 5 Stems

Stems are divided into….

Purpose of Stems • Support • Transport nutrients & food • Store some nutrients

Stolon

Rhizomes

Corm

Bulb

Tubers

Xeromorphic Plants Thick-walled epidermis covered with waxy cuticle (holds water in stems)

Chapter 6 Leaves

Interior Parts of Leaf

View Guard Cells & Stomata of Wandering Jew

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

Sac leaves

Leaf Arrangements • Simple Leaf – one blade attached to the stem • Compound Leaf – multiple leaves attached to stem through petiole • Palmate – Leaves come together like a palm • Pinnately – leaves separated by divisions

Chapter 7 Flowers

Parts of a Perfect Flower

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