An Amoeba forms a new food vacuole every 8 minutes…
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
An Amoeba forms a new food vacuole every minutes. Each vacuole holds small bacteria.
- How many food vacuoles does it form in hours?
- How many bacteria does it take in during that time?
Need a reminder? The key ideaShow
Holozoic: whole food taken in and digested inside. Saprophytic: food digested outside the body on dead matter, then absorbed. Parasitic: food taken from a living host. Amoeba traps food in a food vacuole with pseudopodia; Paramecium sweeps it into a fixed groove with cilia.
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.
Step 1. Minutes. minutes.
Step 2. Vacuoles. food vacuoles.
Step 3. Bacteria. bacteria.
Answer: food vacuoles and bacteria.
