Answer:
- plant cell:It has cell wall
- plastids are present
- centrosome is absent
- Animal cell:cell wall is absent
- plastids are absent
- centrosome is present
Answer:
The plant cell and the animal cell can be differentiated by the presence of organelles in them. Although both are classified as Eukaryotes, the presence of the cell wall, vacuoles, and chloroplasts are the most remarkable and distinguishing components of the plant cells which are absent in the animal cells. Even the size of the animal cell is smaller than the plant cell.
The concept of cell originated from the historical work done by the Schleiden and Schwann in 1838. Cells exist in an amazing variety of sizes and shapes. Likewise the living beings, the individual cells that form the body can grow, reproduce, process information, as well respond to stimuli. Despite the differences among different kinds of the cells whether it is plant cell or animal cell, single celled or multi cell, they all share certain common features and carry out different complicated process in the almost same way.
The multicellular organisms contain billions or trillions of cells organized complexly, while unicellular consist of the single cell only. But even that single cell organisms will define itself by exhibiting all the remarkable properties that a cell needs to become a fundamental and structural unit of life. In this content, we will take-up the salient features of the plant cells and animal cells and how they differ from each other.
Explanation:
BASIS FOR COMPARISON PLANT CELL ANIMAL CELL
Meaning The fundamental and functional unit of Kingdom Plantae of the Eukaryotic cells, having true nucleus along with the many organelles, specially the cell wall, chloroplast and the vacuoles. Animal cells are also the basic unit of life of Kingdom Animalia of the Eukaryotic cells, having all the necessary organelles with specified functions.
Cell Size Usually larger, which is fixed. Smaller in size and irregular.
Cell Shape Rectangular. Round.
Enclosed by A plant cell is enclosed by rigid cell wall along with the plasma membrane. The animal cell is enclosed by a flexible, thin plasma membrane only.
Nucleus Present and lies on one side of the cell. Present and lies in the centre of the cell wall.
Centrosomes/Centrioles Absent Present
Plastids Present with chloroplast in them. Plastids are absent.
Cilia Absent. Usually present.
Glyoxysomes May be present. Absent.
Plasmodesmata Present. Absent.
Desmosomes/Tight junction Absent. Present.
Mitochondria Present in fewer number. Present in large number.
Vacuoles Only one huge vacuole. Animal cells contain many in numbers.
Lysosomes Rarely noticed in plant cells. Present.
Chloroplast Plant cell contains chloroplast, which they use in storing energy. Animal cells lack chloroplast and use mitochondria for energy storing purpose.
Reserve food Present as starch. Present as glycogen.
Synthesis of nutrients They can synthesize all amino acids, vitamins and coenzymes. They are not able to synthesize any amino acids, vitamins and coenzymes required by them.
Cytokinesis Occurs by cell plate only. Occurs by furrowing or constrictions.
Hypotonic/Hypertonic Solutions Plant cell does not burst if placed in hypotonic solution. Animal cells burst in hypertonic solution as they do not have the cell wall.
