Question

Which of the following statements is true for animal cells?
A. They have a definite structure.
B. They have an independent structure.
C. They lack a cell wall.
D. They can have chloroplast.

Answer 1

An animal cell contains cell membrane, nucleus, vacuole, Golgi apparatus, ribosome, mitochondria, lysosome, etc. Cell is known as the structural and functional unit of life.

Complete Answer:
- Cells actually have certain unique components known as cell organelles. There are various type of cell organelles found in cell including plasma membrane or cell wall, nucleus, cytoplasm, endoplasmic reticulum, mitochondria, Golgi apparatus, chloroplasts, lysosomes, vacuoles, etc.
- Every type of cell organelle has a special function, such as the creation of new materials in the cell and the removal of waste from the cell. Thanks to these organelles a cell will survive and fulfill all its functions.
- Together they form the basic unit known as the cell. It is important to note that all cells have the same organelles, regardless of their role or species. But, some extra cell organelles are present in case of plant cells.
- The cell of the plant is rectangular and larger relative to the animal cell. While plant and animal cells are eukaryotic and share several cell organelles, they have quite different roles in comparison with animal cells. A plant cell contains a cell wall, cell membrane, nucleus, plastid, central vacuole, Golgi apparatus, ribosome, mitochondria, lysosome, etc. An animal cell does not have a cell wall and plastids.

Thus, the correct answer is option C. i.e Animal cell lacks a cell wall.

Note: A cell of a plant is encircled by a cell wall. A cell wall composed of fungal Chitin surrounds the fungal cell. A bacterial cell often has a cell wall around it. Peptidoglycan is a bacterial cell wall. In an animal cell, the cell wall is lacking. The most important distinction between a plant and an animal cell is the presence or absence of a cell wall.
