Answer:

A sperm fertilizes the egg and they fuse together to become a zygote. The zygote is then implanted the Uterus which marks the beginning of embryonic development.After which the cells proliferate and gives rise to cells of many different types. The cells usually have different structures according to their corresponding function.

Cells make proteins and it varies according to their functions. Example include red blood cells which is the only cell that contain the protein haemoglobin which carries oxygen around your body.

What organelle wouldn’t have a job if the smooth and rough ER didn’t work?

ruslelena [56]

Answer: The Golgi apparatus.

Explanation: I believe it is the Golgi apparatus as the Rough ER and Smooth ER create proteins and sort them in to piles before sending to the Golgi apparatus to deliver.

The Smooth ER and Rough ER are like the suppliers while the Golgi apparatus is like the transporter.

Remember: Proteins have many functions and are needed severely to perform those actions that without the Golgi apparatus, those proteins wouldn’t be able to be transported.
