During division, cell organelles such as mitochondria and chloroplasts '''become distributed''' evenly between the cells. In animal cells, division is by '''in-tucking''' of the plasma membrane at the equator of the spindle, ''''pinching'''' the cytoplasm in half (Figure 3.15). In plant cells, the Golgi apparatus forms vesicles of new cell wall materials which '''collect along the line of the equator''' of the spindle, known as the cell plate. Here, the '''vesicles coalesce''' forming the new plasma membranes and cell walls between the two cells (Figure 3.17).}}</ref>]]
 
'''Motility''' is the ability of an [[organism]] to move independently, using metabolic energy.
 
This trait is genetically determined and can be influenced by environmental factors like toxins. Most animals and many microorganisms, including bacteria, display motility. In addition to locomotion, motility also includes the movement of food through an organism's digestive tract, facilitated by smooth muscles in the gastrointestinal tract. At the cellular level, movement modes include amoeboid movement, filopodia, flagellar motility, gliding, swarming, and twitching motility. Not all cells are motile, and their movement can be influenced by various factors including chemical gradients, temperature gradients, light gradients, magnetic fields, electric fields, gravitational force, rigidity gradients, cell adhesion sites, and other cells or biopolymers.
