Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

Angiosperms can be dioecious or monoecious and they go through sexual production (Raghavan, 1999). Angiosperm flowers are considered to be hermaphroditic or androgynous because the same flower contains both female and male gametophytes. However, angiosperm flowers with only female gametophytes are incomplete and considered to be either a carpellate flower containing only female parts or a staminate flower containing only male structures. The male reproductive structure of the angiosperms is known as andoecium. The anthers that are found in the stamens of the angiosperms contain pollen sacks, which have the microsporocytes. The cells go through a process known as ...

What are the female reproductive parts of the angiosperm flower?

The female reproductive parts of a flower include the stigma, the ovary, and the style. Their collective name is normally referred to as carpel. a flower may be composed of one or several pistils. For reproduction to occur, all these parts play an important role. The stigma is the female part of a flower that receives pollen grains. It normally has a sticky surface to enable pollen grain to stick and germinate on it. There are several shapes of the stigma. The different shapes enable them to be well adapted to their role in reproduction. Some of the shapes ...

Abstract

This examination paper acknowledges the spectacular diversity of reproductive adaptations for survival of various categories of land plants. It describes a typical life cycle of a land plant that reproduces via spores. It also identifies the different parts of Plant organs and their functions such as cell organelles, parts of a land plant, and epidermal cells. A microscope is an important tool for examination of biological specimens, including cell’s internal structures called organelle and is important in magnifying the focused area. Plants are classified into four main groups, namely, ferns, mosses, flowering and confers. This paper finds that ...
