Botany MCQs for NEET — Practice Questions with Answers

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 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 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 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.

Leaves are attached to the stem at nodes. Nodes are the specific points on a stem where leaves, branches, and aerial roots grow from. The region between two nodes is called the internode.

Phyllotaxy refers to the arrangement of leaves on the stem of a plant. This arrangement is crucial for maximizing light capture for photosynthesis and can vary between species, including alternate, opposite, and whorled arrangements.

Bulbils are small bulb-like structures that can form on various plants. They take part in vegetative reproduction, which is a form of asexual reproduction where new plants grow from fragments of the parent plant.

In a bulb, the stem is very much reduced and is modified into a disk-like structure. The bulb consists of a short stem surrounded by fleshy scale leaves that store nutrients.
