Question

Could you please give a definition for an organelles

Answer 1

An organelle is a specialised part of the cell that serves a specific purpose within the cell. There are many organelles present within a cell and they also vary depending on what kind of cell we are talking about, whether it be a plant or animal cell.

Here are a few of the organelles and their functions:

• nucleus-this would be like the brain of the cell and gives direction to the rest of the cell
• cell membrane-this provides protection for the cell and allows material to enter and leave the cell
• vacuoles-these are used for storage of materials such as water
• mitochondria-this is the powerhouse of the cell-it has ATP (energy)
• endoplasmic reticulum-this is sort of like circulation for the cell-its use is for transportation

Plant cells have chloroplasts which have chlorophyll and a cell wall.
