3. What is the classification of plants on the basis of their size and structure?

Classification of plants

1) Based on the size, nature of the stem and the life span, plants are classified into herbs, shrubs and trees There is one more category called as creepers and climbers. a) A herb is a non-woody plant that has green and tender stem with few branches on.

4. How many types of root systems are found in plants?

two

There are two main types of root systems. Dicots have a tap root system, while monocots have a fibrous root system, which is also known as an adventitious root system. A tap root system has a main root that grows down vertically, from which many smaller lateral roots arise.

5. Define the tap root system.

Taproot, main root of a primary root system, growing vertically downward. Most dicotyledonous plants (see cotyledon), such as dandelions, produce taproots, and some, such as the edible roots of carrots and beets, are specialized for food storage.

6. What is the role of pollination in diversity?

Many ecosystems, including many agro-ecosystems, depend on pollinator diversity to maintain overall biological diversity. Pollination also benefits society by increasing food security and improving livelihoods. ... Therefore pollinators are essential for diversity in diet and for the maintenance of natural resources.

4) Plants have three types of root systems: 1.) taproot, with a main taproot that is larger and grows faster than the branch roots; 2.) fibrous, with all roots about the same size; 3.) adventitious, roots that form on any plant part other than the roots.
