Angiosperms have a wide distribution in the biosphere and the largest number of species in the plant kingdom. An angiosperm is seed plant that produces flowers and fruits. Angiosperms are divided into monocots and eudicots. They are classified in Anthophyta. There are four structures for reproduction found in angiosperms. These structures include fruits‚ petals‚ stamen‚ and carpel. Fruits‚ which are the matured ovaries of plants helps to disperse the seeds of angiosperms. By being tasteful‚ more

The pitcher trap evolved independently in three eudicot lineages and one monocot lineage‚ representing a case of convergent evolution.[2] Some pitcher plant families (such as Nepenthaceae) are placed within clades consisting mostly of flypaper traps‚ indicating that some pitchers may have evolved from the common ancestors of today’s

a schoo Chapter 35 The Plant Body 1. Describe and compare the three basic organs of vascular plants. Explain how these basic organs are interdependent. The three basic organs of a vascular plant are the stems‚ leaves‚ and roots. The stems consist of nodes‚ where leaves attach‚ and internodes between the nodes. The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients
