Plant cells are eukaryotic cells present in green plants , photosynthetic eukaryotes of the kingdom Plantae. Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or centrioles , except in the gametes, and a unique method of cell division involving the formation of a cell plate or phragmoplast that separates the new daughter cells. Plant cells differentiate from undifferentiated meristematic cells analogous to the stem cells of animals to form the major classes of cells and tissues of roots , stems , leaves , flowers , and reproductive structures, each of which may be composed of several cell types.

Animal cells usually have an irregular shape, and plant cells usually have a regular shape. Cells are made up of different parts. It is easier to describe these parts by using diagrams:. Animal cells and plant cells both contain:. Plant cells also contain these parts, which are not found in animal cells:. The table summarises the functions of these parts:.
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia. Most cells, both animal and plant, range in size between 1 and micrometers and are thus visible only with the aid of a microscope. The lack of a rigid cell wall allowed animals to develop a greater diversity of cell types, tissues, and organs. The ability to move about by the use of specialized muscle tissues is a hallmark of the animal world, though a few animals, primarily sponges, do not possess differentiated tissues.

Although they are both eukaryotic cells, there are unique structural differences between animal and plant cells. Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells. While both animal and plant cells have microtubule organizing centers MTOCs , animal cells also have centrioles associated with the MTOC: a complex called the centrosome. Animal cells each have a centrosome and lysosomes, whereas plant cells do not.
Plant Cell Structure and Ultrastructure
Respiration occurs in every cell of your body. To understand respiration you maty need to find out more about cells and how they work. Do you know what the major organelles of the cell are called, and what each of these structures does? Click on the labels around the cell if you want to find out more!

specific cell components/organelles for functional and cellulose of the plant cell wall and most of the glycosaminoglycans of animal extracellular matrix.
1. A guide to plant cell organelles
The animal cell parts and functions all are performed by the various cell organelles. These types of cell organelles function like a unit and regulate the actions of the cell on the whole. Most animal cells have at least the three main parts: nucleus, cell membrane, and cytoplasm. The nucleus of the cell gives the cell direction. It directs all activity of the cell.
Animal cell diagram. Fly or die unblocked hacked. Part Three - Labeling the Diagram Label the diagram below with the following parts: chloroplast, contractile vacuole, flagellum, nucleus, paramylon granule, pellicle, and eye spot stigma Blank labeled diagram of the euglena. Great for new teachers, student teachers , homeschooling and teachers who like creative ways to teach. Draw a diagram of one cheek cell and label the parts. You should observe the cell membrane, nucleus, and cytoplasm.
You can have games and crafts based on sea animals. See the differences between plant cell and animal cell in terms of cell organelles and other components. Just as the human body has organs that do specific jobs, cells have organelles, or little organs, that do specific jobs in the cell. List other cell parts under the tab for the correct cell type. Plant cells are made up of many tiny parts, each with a specific job.
