section 1

seed plants: those plants that make seeds

flowers: The reproductive structure of some seed-bearing plants

cones: a shape whose base is a circle and whose sides taper up to a point

leaves: In botany, a leaf is an above-ground plant organ specialized for photosynthesis.

seeds: A seed (in some plants, referred to as a kernel) is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food.

stems: The stem supports the plant and is characterized by having buds and leaves.


roots: the process of putting forth roots and beginning to grow

capillary action: movement of a 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 by which plants use light energy, carbon dioxide, and water to make their own food

diffusion: the movement of particles from an area of high concentration to an area with low concentration

active transport: the process in which large particles cross the cell membrane; active transport requires energy

transpiration: the plant process that pulls the water up from the roots

cellular respiration: process in which cells break down sugar particles into carbon dioxide, water, and energy

osmosis: in cells, the movement of water across a cell membrane

germination: the process where by seeds or spores sprout and begin to grow

seed stage: a stage where the seed begins to grow

seedling stage: a stage where the seedling begins to grow and become a seed

adult stage: the stage where the adult part of the plant begins to die off so that it can make new seedlings and make ore of the species and reproduce

pollination: the process in which male and female parts of a plant join to produce a seed

pollen: the male part of a seed plant that unites with the female part to produce a seed; pollen is produced by either flowers or male cones

ovule: the female part of a seed plant that joins with a male part to produce a seed; ovules are usually found inside an ovary

ovary: a protective structure on a seed plant that contains the ovule; ovaries are often in the center of a flower or on a female cone

pollinators: an orgasm 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: Stems, roots, or leaves taken from plants for propagation

grafting: a 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

shelter: a structure that provides privacy and protection from danger

food production: where the plant produces its own food

soil: earth material composed of rock particles and decaying organic matter

erosion: the process that moves soil from one place to another

organisms: living things

food: any substance that can be metabolized by an animal to give energy and build tissue

fibre: thin thread of a natural or artificial substance

medicine: the branches of medical science that deal with nonsurgical techniques

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 takes care of itself

managed living resources: a living resource that is being used by humans to meet our needs

section 3

mineral particles: particles in soil that come from rock that has been broken down

organic particles: particles in soil that come from plants and animals that have died: humus is composed of organic particles

humus: partly decomposed material from plants and animals that once were living

sandy soil: Determined by particle size. Sandy soils have large particles, are loosely arranged, and do not hold water

clay soil: Soil with very small, flat particles that tend to pack together tightly, hardens when dry, and drains poorly without organic amendments

loam soil: Loam is soil composed of sand, silt, and clay in relatively even concentration (about 40-40-20% concentration respectively),

organic fertilizer: a mixture of nutrients prepared from natural resources such as animal or plant waste

chemical fertilizer: a nutrient mix made from chemicals

irrigation: the practice of applying water to crops

clearing: a tract of land with few or no trees in the middle of a wooded area

plowing: the practice of cutting into soil and turning its top layer over

crop rotation: the practice of planting a different crop in a particular field each year

section 4


population: all individuals of one species living in a certain place at the same time

yield: the amount of use full plant material produced per plant, or per area planted in a particular crop

hydroponics: a technology for growing plants in which the plant roots are placed in a nutrients solution instead of soil

conditions: the prevailing context that influences the performance or the outcome of a process

artificial: not according to nature; not by natural means; "artificially induced conditions"

species: living things of the same kind that are able to reproduce

variety: a group of organisms of the same species that has specific characteristics that could distinguish it from other varieties of that species

trait: a characteristic of an orgasm

selective breeding: a technology for producing new varieties of an orgasm that involves choosing parents if desired traits in order to produce offspring with these traits

genes: tiny piece of material in a cells nucleus; each gene in a cell is responsible for the inheritance of certain traits or characteristics

genetic engineering: process in which single genes are added to a plant's genetic material

offspring: the product of reproduction; i.e., the individuals produced by parents

consequences: something that wasnt meant to happen

herbicide: a chemical that kills unwanted plants

pesticide: chemicals that are poisonous to insects

biological control: a technology for controlling pests in which the natural preditors of the pest are introduced into an environment to reduce their population size

resistant: "the new hybrid is more resistant to drought"

unintended consequences: results of an action that were not predicted or planned

environmental management: the process of balancing the needs of humans with the needs of the environment

biodiversity: the diversity of plant and animal life in a particular habitat (or in the world as a whole); "a high level of biodiversity is desirable"
