3       Cell organelles with their structure and function

cell wall - a thick, rigid membrane that surrounds a plant cell. It gives the cell most of its

support and structure. The cell wall also bonds with other cell walls to form the structure

of the plant. Not found in animal cells.

 cell membrane - the thin layer that surrounds the cell, but is inside the cell wall. The cell

membrane is semipermeable, allowing some substances to pass into the cell and blocking others. Animal cells have this as their outermost layer as they do not have a cell wall.

 nucleus - spherical body containing many organelles, including the nucleolus. The

nucleus controls many of the functions of the cell kind of like an instructor. It is round

and near the cell centre.

 nucleolus - an organelle that is a small round body of protein in a cell nucleus.

 cytoplasm - the jellylike material outside the cell nucleus in which the organelles are

located, they all sort of float in it.

 vacuole - a large, membrane-bound space within a plant cell that is filled with fluid. Most

plant cells have a single vacuole that takes up much of the cell. It helps maintain the

shape of the cell and can be considered the storage warehouse. Animal cells likely have

several small vacuoles in the cell.

 mitochondrion - converts the energy stored in glucose, sort of a power plant.

 chloroplast - contains chlorophyll and uses the sun energy to convert it into chemical

energy. It is usually represented as an oblong shape with lines in it. Not found in animal


golgi complex - a flattened, layered, sac-like organelle that looks like a stack of

pancakes. The golgi is like a packaging plant that gets things ready to be sent out.

 ribosome –is where proteins are assembled, small round like balls.

 endoplasmic reticulum – this organelle is a maze of tubes or tunnels several in each cell.

 lysosome – these organelles contain enzymes that aid in the digestion of nutrient

molecules and other materials, they can be described as the stomach of the cell.

They can be identified as looking like rods in the animal cells and are not found in plant


 Cytoplasm - It is not considered as an organelle but is an important part of a cell. It is the a jelly-like fluid that fills a cell. Cytoplasm is also known as cytosol. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and  the organelles are suspended in the cytoplasm.
