Solution and Explanation

In angiosperms, the anthers are mostly the male reproductive structures that produce and contain the pollen grains. Anthers are part of the flower's stamen and are usually located at the top of a thin stalk called the filament. The anthers are composed of two lobes called microsporangia, which contain the microsporocytes, the cells that undergo meiosis to produce the microspores. The microspores then develop into the male gametophyte or pollen grain. The shape, size, and number of anthers can vary among different species of angiosperms. For example, some flowers have only one anther, while others may have multiple anthers fused together in a ring or in other configurations.

Structural Organisation in Animals

Structural organization in animals refers to the different levels of organization within their body, from the smallest unit of life to the entire organism.

At the cellular level, animals are composed of various types of cells that perform specific functions. These cells are organized into tissues, which are groups of similar cells that work together to perform a specific function. Different tissues then combine to form organs, such as the heart, lungs, and liver, which have specific functions within the body.

Multiple organs that work together towards a common goal make up an organ system, such as the respiratory or digestive system. Finally, all of the organ systems work together to form the entire organism.

The organization of an animal's body is critical to its survival and adaptation to its environment. Each level of organization is complex and requires a high degree of coordination and communication among cells, tissues, organs, and organ systems. The study of structural organization is important in understanding how animals function and how they adapt to their environment.
