Cell Structure
The knowledge and concept about the structure of the cells have changed constantly over the past years. Primarily the scientist defines the cells as a simple membranous sac with fluids and some particles. Researches have now revealed that the cell is the more complex and basic unit of life. There are different types of cells and they also differ in shape and structure. The basic three parts of a cell are cell membrane, cytoplasm, and organelle.
Plant Cell
The smallest functional unit of a living organism is known as the cell. It is composed of cytoplasm enclosed by an outer layer known as the cell membrane. A cell is classified as a prokaryotic cell and a eukaryotic cell. A prokaryotic cell does not contain a nucleus, and the genetic material is freely suspended in the cell cytoplasm; for example, bacteria are composed of a prokaryotic cell. Whereas a eukaryotic cell contains a nucleus and membrane-bound cell organelles with a specific function, plants and animal cells are examples of eukaryotic cells.
Plant Cell Types
Plants are made up of a variety of cell types that include both living and dead cells. These cells provide them mechanical and structural support along with the growth of plants. Plant tissue is a group or collection of cells, which are similar in structure and work together to accomplish a specific function. Plant cells are most similar to animal cells, both being eukaryotic cells.
because of the fallowing:
Chloroplasts (note: in addition to mitochondria) Cell walls Vacuoles
what can plant cells do that animal cells cannot?
The question asks about the functions of the cell wall, vacuoles, and chloroplasts in a plant cell but absents in animal cells.
Chloroplasts are the plastids present in cells of the green plant that comprises of chlorophyll. The photosynthesis takes place in these organelles. It is absent in animal cells.
Function present in a plant cell but absent in animal cell:
Chloroplasts help in the conversion of light energy from the sun into (carbohydrates) sugars which can be used by the plant cells. The phenomenon is known as photosynthesis. It depends on the chlorophyll molecules present in each chloroplast.
The cell wall is a rigid layer made up of polysaccharides. It is located outside the plasma membrane of the plant cells, bacteria, and fungi. It is absent in animal cells. In the higher plants and algae, the cell wall is comprised mainly of the cellulose.
Function present in a plant cell but absent in animal cell:
The cell wall is the semi-permeable, protective, and outer layer of a plant cell. The most important function of the cell wall is to provide the cell strength and structure, It is helpful to filter the molecules which can pass inside and outside of the cell.
