Corrected sentence: Blood is made of cells that float in yellowish plasma.
Why this change?
- Don’t use all caps: Writing PLASMA in all capital letters looks like shouting. Use plasma (lowercase).
- Better word choice: 'Swim' is a fine picture, but 'float' is more accurate for how blood cells move inside plasma.
- Keep it simple: 'Yellowish plasma' is okay, or you can say 'a yellowish liquid called plasma' to help explain what plasma is.
Other simple versions you can use:
- Blood is made of cells that swim in yellowish plasma.
- Blood is made of cells that float in a yellowish liquid called plasma.
- Blood is made up of red and white blood cells that float in yellowish plasma.
