PLANT PARTS
This plant part absorbs water and helps anchor the plant in soil.
What are roots?
This process allows plants to make their own food using sunlight.
What is photosynthesis?
This is the term for a seed beginning to grow.
What is germination?
Dark soil usually means there is a lot of this present.
What is organic matter (humus)?
This method grows plants without using soil.
What is hydroponics?
Plants are used by humans to make medicine, shelter, fuel, and this basic need.
What is food?
This flower part produces and holds pollen.
What is the anther?
This force moves water upward through plant tubes without a pump.
What is capillary action?
This seed structure stores food for the developing plant.
What is the cotyledon?
A white crust on soil can form when this farming practice is overused.
What is irrigation?
Growing only one type of crop over a large area is called this.
What is monoculture?
This concept means meeting today’s needs without harming future generations.
What is sustainability?
These are two important jobs done by stems: support and transport.
What are supporting the plant and moving water/nutrients? (or food storage)
Most water loss in plants happens through leaves because they have many of these.
What are stomata?
This must happen before a seed can form in flowering plants.
What is pollination?
Plant roots grow best in soil that has both water and this.
What is air (air spaces)?
(nutrients will give you 50 points... but if you named NPK 150)
These structures allow farmers to control temperature, light, and moisture.
What are greenhouses?
Plants are called producers because they can do this.
What is make their own food?
These tiny openings in leaves control gas exchange and water loss.
What are stomata?
One process moves particles from high to low concentration, while the other requires a membrane and water.
What are diffusion and osmosis?
Cutting, layering, and grafting are examples of this type of reproduction.
What is asexual reproduction?
Farmers use this practice to prevent nutrient loss and reduce pest problems in soil.
What is crop rotation?
This pest control method uses natural predators instead of chemicals.
What is biological control?
This occurs when toxins build up in organisms higher in the food chain.
What is bioaccumulation?
Because roots hold soil together, they help prevent this environmental problem.
What is erosion?
This plant process is essential to animals because it produces food and oxygen.
What is photosynthesis?
Farmers often use this type of reproduction because it creates identical plants with desired traits.
What is asexual reproduction?
Adding compost or organic matter improves soil by increasing this property.
What is soil fertility?
Too much fertilizer can reduce yields because plants reach a limit or soil becomes damaged.
What is diminishing returns / over-fertilization?
Farming practices that protect soil, water, and ecosystems help achieve this long-term goal.
What is sustainability?
