Plant Diseases Identification Quiz

Scab spots appear as brown, roughened areas due to a fungal infection affecting the ______

Powdery mildew appears as a dusty white to gray coating over leaf surfaces and other infected plant parts, affecting the ______

Rust is most often found on mature plants where symptoms primarily appear on the surfaces of lower leaves, affecting the ______

Verticillium Wilt is a persistent soil-borne disease affecting fruits and vegetables, especially tomatoes, potatoes, peppers, and eggplant, inhibiting the absorption of ______

Abscisic Acid is a hormone involved in protecting plants from environmental stress, such as nutrient starvation, and plays a role in adaptation to environmental stress, seed germination, and plant defense responses, including the regulation of ______

Brassinosteroids are structurally related to animal steroid hormones and are responsible for regulating plant defense from pathogens, growth, development, physiological responses, and abiotic stress responses, including seed germination and reproductive development, as well as the regulation of stem-cell related genes and cell differentiation, and chloroplast formation during ______

Plants must get materials for growth from their ______

Leaves are entry and exit points for the ______ needed by plants

Stems connect the roots to the leaves, flowers, and fruits, containing cells adapted for transportation of water, minerals, and ______

Roots absorb water and minerals from the ______

Xylem cells transport water and minerals up the stem from the roots to the shoots and leaves, this transport occurs in one direction ______

Plants contain two types of cell adapted for transportation: Xylem cells transport water and minerals, while ______ transport nutrients

Plants trigger physiological and developmental responses to acquire nutrients by altering the whole plant morphology and metabolism. Some responses lead to an induced expression of chemical transporters and collection of enzymes and compounds to remobilize the sources present. These responses are part of the plant's ________ mechanisms.

To cope with limited access of nutrients due to irregular patchy distribution in most soils, plants utilize ________ mechanisms to increase or decrease growth in organs involved in nutrient acquisition.

Anthracnose is generally found in the eastern part of the U.S. and infected plants develop dark lesions on stems, leaves, or fruit. The disease affects the plant's ________ vessels.

Apple scab symptoms on fruit are similar to those found on leaves. Scabby spots are sunken and may have velvety spores in the center. This disease impacts the plant's ________ cells.

Bacterial canker infection causes sunken, oozing cankers to form on many stone fruits. This infection directly affects the plant's ________ cells.

Plants employ adaptive mechanisms to increase or decrease growth in organs that are directly or indirectly involved in nutrient acquisition. These mechanisms play a crucial role in the plant's ability to optimize ________ absorption.
