Discuss the adaptations that have enabled flowering plants to overcome the following problems associated with life on land. Be very specific in your description of the adaptations which help angiosperm survive in a land based environment as opposed to an aquatic environment. There are multiple adaptations. Study this before trying to write so that you can include a variety of features. a) The absence of an aquatic environment for reproduction. b) The absence of an aquatic environment to support the plant body c) Dehydration of the plant

a) specialized structures and organs for reproduction (flowers)

b) lignin in the xylem

c) waxy cuticle, stomata

Explanation:

a) Angiosperms have flowers, which are specialized reproductive organs. Flowers contain specialized reproductive cells (i.e., pollen cells) which can be dispersed by wind or animals.

b) Plant tissues can be covered by a waxy cuticle that helps to conserve water and tiny pores called 'stomata' in the epidermis that close in order to prevent water loss.

c) Finally, the xylem in land plants provides mechanical support. The cell walls of the xylem are composed of lignin, an organic substance that provides structural rigidity to the plant fibers.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
