2. Joke of the day

4. A flagellum has an undulatory movement.
Force is generated parallel to the flagellum’s axis.
Like cilia but can be very much longer.
Also for locomotion of organisms and gametes (sperm).

5. Cilia move more like oars with alternating power and recovery strokes.
They generate force perpendicular to the cilia’s axis.

6. Chromatin The hereditary material of the cell.
Condenses to form chromosomes during cell division.
Composed of protein and DNA

7. Chromosomes
Rod-shaped bodies in the nucleus, particularly during cell division.
Contains the hereditary
information (genes)
Condensed chromatin

8. Each eukaryotic species has a characteristic number of chromosomes.
A typical human cell has 46 chromosomes, but sex cells (eggs and sperm) have only 23 chromosomes.
