plant needs

light, needed 4 photosynthesis, water, moves nutrients, nutrients, gives energy,materials for plants to grow. space, needed to grow

what does nutrients inculde

nitrogen, phosphorus, potassium, calcium\, magnesium

what do plants provide

food, oxygen, shelter

plant uses

1 food, 2 medicine 3 fibre 4, fuel 5 transportation

soil types

sandy, light brown, made of minerals, no humus. clay, hard,dry, no humus. loam, dark brown balance between organic or mineral materials

managing soil

fertalizer, irrigation, clearing land, plowing

farming practices

crop roation, growing diff crops in diff fields, 0 tillage, shelter belts vegetative cover

growing environments

hydroponic, green house, mono-culture,

artificial reproduction types

selective breeding, genetic engineering, human intervention in a plant, create new plant varieties, 2increase or improve yield,flavours,uses

weeds and pests

consume plants,crops needed for humans. can be controlled w/ herbicides,pesticides,biological control

seed plant structures

roots, stems, leaves, flowers, cones, seeds

plant processes (water)

osmosis, capillary action, transpiration\

plant processes ( nutrient)

diffusion, active transport

plant process (food and use)

photosynthesis, cellular respiration

life cycle

SEED-seedling-adult. seed contains embryo, seedling is embryo that has begun photosynthesis, adult has produced it own reproductive structur

seed plant reproduction

pollination, pollinators

vegetative reproduction

runners,rhizomes,suckers, cuttings/grafting

adaptations

thick stems(stores water, reduce evaporation, protect plants from extreme temps) spines/thorns( protects plants from predators)

adaptations part 2

narrow leaves (help pollinate, reduce water loss) fibrous roots( gathers nutrients from large area around plant)

adaptations part 3

tap roots(gathers nutrients deep in soil or water) wide leaves(helps gather sun for photosynthesis)

adaptations part 4

bright flowers(attracts bugs and birds) Needle leaves(prevent water loss) rapid seed production( enables plants to reproduce in short season
