Describe the differences in the appearance and function of the two cells labelled in the figure.
Answers
Answer:
Animal cells contain a wide variety of parts, each of which plays a vital role in the survival of the cell.
Explanation:
The endoplasmic reticulum is a network of membranes inside a cell, and its main functions are to process and transport new materials. There are two types of endoplasmic reticulum; the rough ER, and the smooth ER.The rough ER is studded with ribosomes, giving it a bumpy or ‘rough’ appearance. It folds and tags newly-synthesized proteins before transporting them to wherever they are needed in the body. The smooth ER does not have ribosomes attached to it and is instead involved in hormone and lipid synthesis.
Golgi Apparatus
Once newly-synthesized substances have left the ER, they are sent to the Golgi apparatus. This is a series of flatted, membrane-bound sacs that packages and distributes substances to the outer cell membrane, where they either become part of the lipid bilayer or leave the cell.
Answer:
Humans are made up of trillions of cells — the basic unit of life on earth. In this article, we explain some of the structures found in cells and describe a few of the many types of cell found in our bodies.
Cells can be thought of as tiny packages that contain minute factories, warehouses, transport systems, and power plants. They function on their own, creating their own energy and self-replicating — the cell is the smallest unit of life that can replicate.
However, cells also communicate with each other and connect to create a solid, well stuck-together animal. Cells build tissues, which form organs; and organs work together to keep the organism alive.
Robert Hook first discovered cells in 1665. He gave them their name because they resembled the cella (Latin for “small rooms”) where monks lived in monasteries
