Organelles Unique To Plant and Animal Cells

In this organelles unique to plant and animal cells post we have briefly explained about organelles present in plant cell and absent in animal cell, organelles unique to animal cells and organelles unique to plant cells.

Organelles Unique To Plant and Animal Cells

Organelles unique to animal cells

Cilia and Flagella

Cilia and flagella are both hair-like organelles found on the surface of many animal cells. The structure of both is identical, with the exception that flagella are longer and whip like and cilia are shorter. A cell typically has only a few flagella, whereas cilia can cover the entire cell’s surface.

Cilia and flagella function as locomotors in one-celled organisms and as transporters of substances across cell surfaces in multi-celled organisms. An animal cell is a type of eukaryotic cell that is found in a variety of tissues in animals. There are numerous cell types. In the adult human body, for example, there are approximately 210 distinct cell types.

Cell Wall

The extracellular structure that surrounds the plasma membrane is known as the cell wall. The cell wall is made up of cellulose, hemicellulose, pectin, and, in many cases, lignin, which is a rigid organelle made of cellulose that lies just outside the cell membrane.

The cell wall is responsible for the plant cell’s box-like shape. It also shields the cell. Pores in the cell wall allow materials to pass to and from the cell membrane. The cell wall is divided into two parts: the primary and secondary cell walls. The primary cell wall is extremely elastic, and after growth is complete, the secondary cell wall forms around the primary cell wall.

Pores in the primary cell wall through which the plasmalemma and endoplasmic Reticulum of Adjacent Cells are Continuous.

Plastids

Plastids are double membrane bound organelles. It is in plastids that plants make and store food. Plastids are found in the cytoplasm and there are two main types: Leucoplasts an colourless organelles which store starch or other plant nutrients. (Example: starch stored in a potato)

Chromoplasts contain different coloured pigments. The most important type of chromoplast is the chloroplast, which contains the green pigment chlorophyll. This is important in the process of photosynthesis. The other plastids is elaioplasts specialized for fat storage As in mitochondria, which have a genome encoding 37 genes, plastids have their own genomes of about 100–120 unique genes.

Central Vacuole

Organelles Present In Plant Cell and Absent In Animal Cell: Central Vacuole

It is found in the centre and large fluid-filled vacuole of plants, which is surrounded by a membrane known as the tonoplast. The function is to maintain the cell’s turgor, pressure, and storage by controlling the movement of molecules between the cytosol and sap, as well as to digest waste proteins and organelles.
