Leaves- A leaf is a above ground plant organ specialized for photosynthesis
Seeds- A plant reproduction part which can travel by wind, water, and animals.
Stems- The above ground structures that have vascular tissue and support leaves and flowers.
Roots- The usually underground portion of a plant that lacks buds, leaves, or nodes and serves as support, draws minerals and water from the surrounding soil and sometimes stores food.
Capillary action-Movement of liquid up a narrow tube; happens when attraction of liquid particles to each other is less than their attraction to the walls of the tube.
Photosynthesis-process in which plants use light, energy,carbon dioxide and, water to make their own food.
Osmosis- In cells, the movement of water across the cell membrane.
Germination- The process of germinating; the begining of vegetation or growth in a seed or plant; the first development of germ, either animal or vegetable.
Seed stage- A seed has three main parts: the embryo, stored food, and a seed coat.
Seedling stage- Plants in the seedling stage grow very fast and produce new leaves, roots and, stems.
Adult stage- A plant is an adult when it produce reproductive parts.
Pollination- The transfer of pollen grains to a stigma.
Pollen- The male part of a seed plant that unites with the female part to produce a seed.
Ovule- The female part of a seed plant that joins with the middle part to produce a seed.
Ovary- A protective structure on a seed plant that contains the ovule.
Pollinators- An organism that carries pollen from one flower to another.
Runners- Long stems that grow along the soil of the surface and produce new plants.
Rhizomes- Stems that grow underground stems and produce new plants
Suckers- New plants that are produced from the roots of the parent plant.
Cuttings- A cut piece of a plant that is used to produce that plant; cuttings usaully have a part of the stem and have a few leaves.
Grafting- Technology to reproduce plants that involves attaching part of one plant to a second plant.
Adaptation- A change in an organism that makes it suited to a particular environment
Section 2.0
Shelter- Something that provides cover or protection Food Production- Producing food
Soil- Earth material composed of rock particles and decaying or organic matter
Erosion- A process that moves soil from one place to another.
Organisms- A living thing.
Food- Is any substance usually composed of carbohydrates, fats, proteins, and water that can be eaten or drank by an animal or human.
Fibre- A natural or synthetic thread that may be spun into yarn.
Medicine- A drug or remedy used for treating illnesses.
Living Resources-Those living things that can be used to meet human needs.
Natural Living Resources- A living resource that has not been changed by humans and that takes care of its self.
Manged Living Resources- A living resource that is being used by humans to meet our needs.
Section 3.0
Mineral Particles- Particles in soil that come from rock that has been broken down Organic Particles- Particles in the soil that come from plants or animals that have died. Humus- Partly decomposed material from plants and animals that were once living
Sandy Soil- A substance consisting of fine loose grains and minerals.
Clay Soil- A soil with lots of humus but, little minerals
Loam- A soil that has a balance of minerals and humus.
Organic Fertilizer- A mixture of of nutrients prepared from a natural source such as a animal or plant.
Chemical Fertilizer- a nutrient mixture made from chemicals.
Irrigation- The practice of applying water to crops.
Clearing- the practice of clearing land to plant crops
Plowing- a practice of cutting into soil.
Crop Rotation-To plant a new crop every season
Section 4.0
Population- all the individuals of a species living in the same place all at one time Yield- The amount of useful plant material per plant.
Hydroponics- a technology for growing plants in which the plant roots are placed in nutrient solution.
Conditions- the flow of energy between substances that are in contact.
Artificial- Something that is not natural matter
Species- living species of the same kind that are able to reproduce.
Variety- a group of organisms of the same species that has specific characteristics.
Trait- a characteristic of a certain species
Selective Breeding- a technology for producing offspring with certain traits
Genes- tiny pieces of material in a cells nucleus
Genetic Engineering- a process of in which single genes are added to a plants genetic material
Offspring- the products of reproduction.
Consequences- something that you know will happen
Herbicide- a chemical which kills of plants
Pesticide- a chemical that kills off pests
Biological Control- a technology for controlling pests
Resistant- no affected
Unintended Consequences- something that you did not aspect
Environmental Management- the process of balancing the needs of human and the needs of the environment
Biodiversity- the number of different species in the same environment
