Feeding the World Lecture

These flashcards cover key vocabulary related to angiosperms, plant biology, agriculture, and environmental issues from the lecture.

Angiosperms

Flowering plants that produce energy-storing seeds within fruit.

Double Fertilization

A process in angiosperms where one sperm fertilizes the egg to form a diploid embryo, and the second sperm fuses with two nuclei to form a triploid cell that develops into endosperm.

Domestication

The process by which wild plants are cultivated and bred for human use, becoming dependent on humans for survival.

Monocot

A class of flowering plants with seeds containing one cotyledon, such as grasses and cereals.

Dicot

A class of flowering plants with seeds containing two cotyledons, such as beans and peas.

Meristematic Tissue

Plant tissue responsible for growth, located at the tips of roots and stems.

Transpiration

The process through which water is absorbed by plant roots and evaporates from aerial parts, especially the leaves.

Xylem

Vascular tissue that carries water and nutrients from the roots to the leaves.

Phloem

Vascular tissue that transports food (sap) throughout the plant.

Eutrophication

A process caused by nutrient pollution, leading to excessive growth of algae and depletion of oxygen in water bodies.

Sustainable Agriculture

Farming practices that meet current needs without compromising the ability of future generations to meet their own needs.

Crop Rotation

The practice of varying the types of crops grown in a particular area over time to improve soil health and fertility.

Plant Growth Requirements

Essential conditions for plant growth including water, light, carbon dioxide, and nutrients from the soil.

Pesticides

Chemicals used to kill or control agricultural pests, including insects and weeds.

Nutrients

Substances that provide nourishment essential for growth and the maintenance of plant life.

Epidermal Tissue

Outer covering of the plant body that helps with water absorption and retention.

Ground Tissue

Plant tissue that performs functions such as photosynthesis and storage.
