Answer:
ans-2. In its simplest form, the term root architecture refers to the spatial configuration of a plant’s root system. This system can be extremely complex and is dependent upon multiple factors such as the species of the plant itself, the composition of the soil and the availability of nutrients. The root of a plant is best defined as the non-leaf, non-nodes bearing parts of the plant's body.
Actually, there are four functions of roots. The first root that comes from a plant is called the radicle. A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem. In response to the concentration of nutrients, roots also synthesise cytokinin, which acts as a signal as to how fast the shoots can grow.
ans-4. The main root (primary root) with other minor side roots, which grow deep into the soil is called Taproot. While the fine, thick hairs like structure, that spread sideways in all the directions is called Fibrous or Adventitious root. Taproot arises from the radicle (embryonic part) of the plants, but the Fibrous root grows from the stem and leaves rather from the radicle
Plants bear parts like stem, leaves, fruits, flowers and most importantly roots. Roots are the underground part, which helps in absorbing nutrients, water, and moisture from the soil. Most flowering plants, shrubs, and trees produce tap roots which can travel deep into the soil, while fibrous or adventitious roots are seen in grasses and reed (tall grasses) plants and grow near to the surface of the soil.

ans-8.The seeds of a flowering plant are surrounded by a tissue called fruit, which may be fleshy or dry.
Explanation:
The functions of the fruit is to protect the seed inside and aid in its dispersal.
Some fruits harden to make accessing the seed difficult.
Many fruits promote wind dispersal .
Some fruits have hooks or spurs, which cling to the skin and fur of animals and are dispersed to far away places.
Fruits like pods rip open forcefully when dry , flinging the seeds away.
Fleshy coloured fruits attract birds and animals and are eaten by them. They pass unharmed through the digestive tract and are thus dispersed away from the parent plant.
