This plant structure absorbs water and dissolved nutrients and anchors the plant in the soil.
What are roots?
The movement of particles from an area of high concentration to an area of low concentration.
What is diffusion?
This process is the transfer of pollen from the anther to the stigma.
What is pollination?
This is partly decomposed organic matter found in soil.
What is humus?
This practice involves supplying water to crops when there is not enough rainfall.
What is irrigation?
These structures produce food for the plant through photosynthesis.
What are leaves?
This process is the movement of water through a semipermeable membrane from high to low water concentration.
What is osmosis?
This male flower structure produces and stores pollen.
What is the anther?
This soil type feels crumbly, is rich in nutrients, and is usually best for plant growth.
What is loam soil?
Scientists develop new plant varieties with desirable traits through this process.
What is selective breeding?
This structure provides a pathway for movement of water and food and supports leaves and flowers.
What is the stem?
This process allows water to evaporate from the surface of leaves.
What is transpiration?
This female flower structure contains ovules.
What is the ovary?
This soil type has large particles, dries quickly, and contains little food for plants.
What is sandy soil?
These are chemicals used to kill weeds.
What are herbicides?
These structures contain an embryo and a food supply for a new plant.
What are seeds?
This process uses sunlight, water, and carbon dioxide to make food.
What is photosynthesis?
Plants that produce cones instead of flowers are called these.
What are conifers?
This soil type can be squeezed into a tight ball and has very small pore spaces.
What is clay soil?
Using a natural predator to control pests is called this.
What is biological control?
Name the two reproductive structures found in seed plants.
What are flowers and cones?
A process that uses energy to move substances in and out of plant cells without requiring a concentration difference.
What is active transport?
Name two methods of vegetative reproduction.
What are cuttings, runners, rhizomes, suckers, or grafting? (Any two)
Farmers use this practice by growing different crops each year to allow nutrients to recover.
What is crop rotation?
Growing only one crop in a field is known as this practice.
What is monoculture?
