Question

Give me some points of structure organisation of a cell in easy language. (GIVE 8 POINTS)

Answer 1

• Cells contain a variety of internal structures called organelles
• An organelle is a cell component that performs a specific function in that cell
• The organelles of a cell maintain the life of the cell.
• There are many different cells; however, there are certain features common to all cells
• The entire cell is surrounded by a thin cell membrane
• All membranes have the same thickness and basic structure
• Organelles often have their own membranes too – once again, these membranes have a similar structure
• The nucleus, mitochondria and chloroplasts all have double membranes, more correctly called envelopes
• Membranes can be used to transport molecules within the cell e.g. endoplasmic reticulum.
• Proteins in the membrane can be used to transport substances across the membrane – e.g. by facilitated diffusion or by active transport.
