Biology

Answer:

Cleavage, in embryology, in the first few cell divisions of the zygote. Initially, the zygote separates into the longitudinal axis. The second division is also longitudinal but at 90 degrees on the first plane. The process produces a multicellular embryo. It is an assembling process that divides the seed into developmental regions. Zygote cytoplasm includes chemicals that control gene expression.

Gastrulation is characterized as an early embryonic phase in which the embryo is converted from a one-dimensional layer of epithelial cells to a multilayer, multidimensional structure called the gastrula.

Organogenesis is a process of embryonic development that occurs at the end of gastrulation and lasts until birth. During organogenesis, the three germ layers formed by gastrulation (ectoderm, endoderm, and mesoderm) form the internal organs.

SVETLANKA909090 [29]

The cell wall, capsule, pilus, and flagella are the bacterial structure that is located on the surface of a bacterial cell.

Cell wall: It is composed of a protein-sugar(polysaccharide) molecule which gives the cell its shape, and rigidity and protects it from the environment.

Capsule: It is a third protective covering that is made up of polysaccharides. It plays many roles but the important ones are to keep the bacterium from drying out and to protect it from engulfing by larger microorganisms.

Pilus: These are specifically small hairlike projections that emerges from the outside of the cell surface. It helps bacteria to attach to the host organism.

Flagella: (singular, flagellum) a hairlike structure that provides a means of location for bacteria. These are mainly found at either or ends of all over its surface.
