Question

Cells evolved cellular compartments to carry out the functions they are specialized for.
Based on this information, compare and contrast red blood cells, sperm cells and muscle
cells for their specific adaptations.

Answer 1

Ans - 1- Adaptations in Red blood cells-

- They contain hemoglobin -a red protein that combines with oxygen .

- They have no nucleus so that they can contain more hemoglobin.

- They are small and flexible so that they can fit through narrow blood vessels.

Ans 2- Adaptations in sperm cells-

- They have a tail to move them towards an egg cell.

- They have many mitochondria to provide energy.

- They have an acrosome (part of the tip of head)that releases enzymes to digest the egg cell membrane.

Ans 3- Adaptations in muscle cells-

- Muscle cells bring parts of the body closer together.

- They contain protein fibres that can contract when energy is available, making the cells shorter .

- They have multiple nuclei since muscle fibres are made when myoblasts fuse together.
