Gov Cup: PLANTS

Plant Facts:

cell wall of cellulose/lignin, perform photosynthesis, eukaryotic & multicellular

General Types of Plants:

Nonvascular/ byrophytes- lack xylem & phloem, tissues that transport substances Vascular- phloem & zylem

Types of Vascular Plants

Seedless- ferns, club, mosses & seeds

Types of Seeded Plants

Gymnosperms- naked seeds that lack the covering, fruit; cones & Angiosperms- flowering plants; fruit, nuts, grains

Dioecious V.S. Monoecious

Di- male and female parts are separate flowers & Mono- male and female parts are in one flower

Photosynthesis:

1 light energy → sugar molecules, by photoautotrophs (plants, algae, cynobacteria)

2 in chloroplast with light absorbing pigment, chlorphyll

3 Light dependent- thylakoid membrane; solar energy →chemical energy, water → oxygen

4 Calvin Cycle/ Light independent- stroma; uses chemical energy, co2 → glucose

Parts of Leafs

3: Blade- collects sunlight, veins- xylem & phloem, petiole- attacher

Leaf Types to Know

Linear- skinny, Oblong- wide and long, Rhomboid- shaped like a rhombus, Deltoid- shaped like a triangle, Elliptical- wide, Ovate- egg shaped

Monocots V.S Diocotes

1 seeded/bladed leaves/ cotyledon, petal pairs in 3 V.S. 2 seeded/bladed leaves, petal pairs in 4/5, older

Simple V.S. Compound Leaves

1 single blade V.S. Multiple blades/leaflets attached to rachis Gr

Grass/ Cereal Family

-Monocots & long/single bladed; Maize- biofuels, wheat-gluten, rice-needs water, oats, barley- beer

Macronutrients for plants

Nitrogen, Phosphorus, and Potassium; dna, rna, formation, enzyme synthesis; color loss, browning

Generational Phases

Sporophytes- grow diploid spores in meisos →gametophytes- produce halfoid gametes → sporophytes ..
