Answer: b. Muscles
A metazoa is a division of animal kingdom that includes all animals expect protozoa and sponges. Metazoa division includes multicelluar animals, which exhibit highly differentiated cells. They have muscular and nerve system and well coordinated tissues and organs. Locomotion requires a coordination activity of muscular, skeletal and neural system. It is mainly achieved by contraction and relaxation of muscles that occurs due to specialized muscle proteins named as actin and myosin which receives signals from nerves.
Hence, locomotion in metazoa is due to contraction of muscles.
The formation of the cell plate takes place during the mitotic phase. In this description we will briefly describe all phases of the cell cycle to paint a complete picture, but feel free to skip to the section labeled “mitotic phase” to get a play-by-play on how the cell plate forms.
The difference between them is that they are active in fighting infection.
Plasma cells are active in defense during the first exposure to invaders like viruses or bacteria producing antibodies. Memory cells last longer and make a copy of the invaders. This allows an extremely rapid defense later in case of a second exposure.
