A plant cell, similar to an animal cell, is eukaryotic.
Eukaryotic cells are characterized by the presence of organelles, particularly the nucleus, as opposed to prokaryotic cells that lack them..

Cell walls are found in most plant cells, bacteria, algae, fungi, and some archaea.
In the cells where a cell wall is present, it forms the outermost layer adjacent to the plasma membrane or cell membrane.
The cell wall is a rigid semi-permeable structure made up of cellulose or chitin..
Plant cells are eukaryotic, which means that they contain a distinct nucleus.
Plant cells have three unique structures which set them apart from other eukaryotes, such as animal cells: the cell wall, plastids, and vacuoles.
Plant cells are microscopic in size (on the order of 0.01 to 1.0 mm.).

A cell is a mass of cytoplasm that is bound externally by a cell membrane.
Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things..
Plant cells are the basic unit of life in organisms of the kingdom Plantae.
They are eukaryotic cells, which have a true nucleus along with specialized structures called organelles that carry out different functions.
Plant cells have special organelles called chloroplasts, which create sugars via photosynthesis..

Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things.
Most cells have one or more nuclei and other organelles that carry out a variety of tasks..
“Plant cells are eukaryotic cells with a true nucleus along with specialized structures called organelles that carry out certain specific functions.”.
Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts.
The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection..
The new cells are usually produced in special regions called meristems (discussed in Chapter 21), and they are generally small in comparison with their final size.
To accommodate subsequent cell growth, their walls, called primary cell walls, are thin and extensible, although tough..
Epidermis.
The plant epidermis is specialised tissue, composed of parenchyma cells, that covers the external surfaces of leaves, stems and roots.
Several cell types may be present in the epidermis..
Plants provide us with oxygen, food, fuel and fiber.
Among other reasons, scientists study plants to improve and secure the food supply for an increasing world population, identify new sources of bioactive compounds and medicines, improve fiber production and identify sources of biofuels and biorenewable resources..
Plant cells do not have cilia, which are short projections from the cell that function in movement, but the sperm cells of early diverging plants, like bryophytes and seedless vascular plants, have flagella.
These are long projections that function in movement.
Plants cells differ from animal cells in that they have a cell wall (which is glued to adjacent cells by the middle lamellae), a large central vacuole, and chloroplasts.
