Pseudopodia are:
Correct answer: A. False feet developed in some unicellular organisms
- A. False feet developed in some unicellular organisms
- B. Small hairlike structures present on the unicellular organisms
- C. Long, tube like structures coming out of the mouth
- D. Suckers which are attached to the walls of intestines
Explanation
A pseudopod or pseudopodia is a temporary arm-like projection of a eukaryotic cell membrane that emerges in the direction of movement. The hair-like projections on unicellular organisms are called Cilia. The long tube-like structure connecting the mouth and the stomach is called the oesophagus. The head of some parasites contains structures, suckers which enable the parasite to attach to the gut wall. So option A is correct

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
