Economic Importance
Many plants belonging to this family are good ornamentals (tulip,
Gloriosa), source of medicine (Aloe), vegetables (Asparagus), and
colchicine (Colchicum autumnale).
Which of the following group show viviparous germination ?
Viviparous germination is a type of germination where the seed germinates while still attached to the parent plant. Rhizophora and Avicennia are examples of such plants, commonly found in mangrove ecosystems.
Fibrous root in maize develop from:
In maize (corn), fibrous roots develop from the lower nodes of the stem. These roots are part of the adventitious root system, which helps in providing additional support to the plant.
Which of the following plants have root pockets?
Eichhornia, commonly known as water hyacinth, has root pockets. These root pockets help in buoyancy and are a characteristic feature of this aquatic plant.
Form which point of root, root hairs develop ?
Root hairs develop from the region of maturation. This region is also known as the zone of differentiation, where cells differentiate and mature into various specialized cells, including root hair cells. Root hairs are important for water and nutrient absorption.
Potatoes are borne on
Potatoes are borne on the axil of scaly leaves. Potatoes are modified stems known as tubers, which develop from the stolons (underground stems) that grow from the axils of the leaves.
Sweet potato is a modification of:
Sweet potato is a modification of an adventitious root. Unlike regular roots, adventitious roots arise from non-root tissues, such as stems or leaves, and they often serve different functions like storage, as seen in sweet potatoes.
Winged petiole is found in;
Winged petioles are typically found in plants of the Citrus genus. The winged petiole is a leaf stalk with a flattened, leaf-like structure along its length, which is a characteristic feature of citrus plants.
