Plant cells differ from animal cells in having______.
A)Cell wall
B)Plastids
C)A large central vacuole
D)All of these
Solution
The plant cells have special organelles called the chloroplasts, which are responsible to create the sugars through the process of photosynthesis. These are the basic units of life in the organisms of the kingdom Plantae. Each of the animal cells has a centrosome and lysosomes, whereas the plant cells do not.
Complete answer:
The cell wall in a plant cell is a rigid covering that protects the cell and also provides structural support and gives the shape to the cell. The chloroplasts which can be seen in the plant cells contain a green pigment known as the chlorophyll which helps to capture the light energy that drives the reactions of plants in the process of photosynthesis. The central vacuole plays an important role in regulating a plant cell’s concentration of water in changing the environmental conditions.
The plant cells contain a cell wall, chloroplasts and also plastids, and a large central vacuole, whereas the animal cells do not.
Both the animal cells and the plant cells have mitochondria, but only the plant cells have the chloroplasts. The plants do not get their sugar from eating food hence they need to make sugar from the sunlight. This is the process of photosynthesis that takes place in the chloroplast. Once the sugar is prepared then it is broken down by the mitochondria to make energy for the cell. Since the animals get sugar from the food they eat, they do not need the chloroplasts they only need mitochondria.
Both the plant cells and the animal cells have vacuoles. A plant cell contains a large, singular vacuole that is used for the storage and maintaining the shape of the cell. In contrast the animal cells have many, smaller vacuoles. The plant cells have a cell wall also containing a cell membrane. In the plant cell wall surrounds the cell membrane. This provides the plant cell its unique rectangular shape. The animal cells simply have a cell membrane, but there is no cell wall.
Hence, the correct answer is option (D)
Note: The plant cells are the building blocks of the plants. The photosynthesis is the major function performed by the plant cells. The process of photosynthesis takes place inside the chloroplasts of the plant cell. It is the process of preparing the food by the plants, by utilizing sunlight, carbon dioxide and water.
