Name the kind of movement (amoeboid, ciliary, flagellar or muscular) in each case.
- A sperm swims toward an ovum.
- A macrophage moves through a tissue and engulfs a germ.
- Dust leaves the airways of a person.
- A student chews a sandwich.
- Euglena swims toward the light.
Which one of the five is not named in the NEET list of movements?
Need a reminder? The key ideaShow
Movement is any change in the position of the body or of a part of it. Locomotion is a voluntary movement that changes the place of the whole body. The kinds of movement are amoeboid, ciliary, flagellar and muscular. About to of the body weight of an adult is muscle.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. Five cases.
Plan. Match each one with its structure of movement.
Step 1. (a) A sperm uses its tail, a flagellum: flagellar movement.
Step 2. (b) A macrophage uses pseudopodia: amoeboid movement.
Step 3. (c) The ciliated epithelium of the trachea sweeps out the dust: ciliary movement.
Step 4. (d) The jaw is moved by muscles: muscular movement.
Step 5. (e) Euglena has a flagellum: flagellar movement.
Answer: (a) flagellar; (b) amoeboid; (c) ciliary; (d) muscular; (e) flagellar. The amoeboid movement in (b) is the one that is not named in the NEET list, which gives ciliary, flagellar and muscular.
Check. Cases (a) and (e) use a single long flagellum, and (c) uses many short cilia.
