Answers
Answer:
1.The main function of a leaf is to carry out photosynthesis, which provides the plant with the food it needs to survive. Plants provide food for all life on the planet.
2.Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.
3.Both creepers and climbers are weak-stemmed plants and, hence, cannot grow erect without support. The difference is that creepers spread horizontally along the soil. At the nodal regions - where leaves grow - they produce fibre-like roots arising from the base of the stem, which get fixed and grow further.
4.Herbs and shrubs are the different types of plants categorized on the basis of their size and branching pattern. Herbs have soft and unbranched stems, whereas, shrubs have woody, branched and multi stems. Shrubs are often confused with herbs because of their similar characteristics, but shrubs are taller than herbs.
