Stem modified into flattened photosynthetic structure is:
Phylloclade is a modified stem that takes on the function of photosynthesis. Unlike leaves, phylloclades are typically flattened and resemble leaves, allowing them to carry out photosynthesis efficiently. Common examples include cacti and certain species of Euphorbia.
Nodulated roots occur in: (R.P.M.T 1995)
Nodulated roots occur in the family Leguminosae (also known as Fabaceae). These roots form a symbiotic relationship with nitrogen-fixing bacteria called Rhizobia, which help in converting atmospheric nitrogen into a form that the plant can use, thereby enriching the soil with nitrogen.
Petiole is modified into tendril in
In Clematis, the petiole is modified into a tendril to help the plant climb and support itself. This modification allows the plant to attach to surrounding structures and grow efficiently.
Vegetative reproduction of Agave occurs through:
Vegetative reproduction in Agave occurs through bulbils. These are small bulb-like structures that form in the axils of leaves or inflorescences. Bulbils can detach and grow into new individual plants, thus aiding in the plant's propagation.
What is the eye of potato ?
The 'eye' of a potato is an axillary bud. These buds are located at the nodes, or 'eyes,' on the tuber and can sprout to form new shoots and eventually new potato plants. This is a common method of asexual reproduction in potatoes.
If a raceme inflorescence is branched , it is call?
In raceme inflorescence, if the main axis branches and each branch bears flowers in a racemose manner, it is called a panicle. A panicle is essentially a branched raceme.
Zig-zag development of inflorescence axis is an example of:
Opposite decussate phyllotaxy is found in:
Opposite decussate phyllotaxy is where pairs of leaves are arranged at right angles to each other along the stem. This pattern is found in plants like Calotropis.
A brightly coloured bract like covering associated with the banana inflorescence is called:
In the banana plant, a brightly coloured, leaf-like structure called a 'spathe' surrounds the inflorescence. The spathe protects the flowers and facilitates pollination by attracting pollinators.
Inflorescence is :
Inflorescence refers to the arrangement of flowers on the floral axis (peduncle). It describes how the flowers are organized and attached to the main stem of the plant. This arrangement can vary widely among plant species and is important for the reproductive process.
