Question

which of the following cell organelle is absent in animal cell but present in plant cell​

Answer 1

Answer:

Cell wall is present in plant cell, but not in animal cell.

Answer 2

Complete Question:

Which of the following cell organelle is absent in animal cells but present in plant cells​?

1. Nucleus

2. Cell membrane

3. Chloroplast

Answer:

Chloroplast is absent in animal cells but is present in plant cells.

Explanation:

• The nucleus is the dominant cell organelle of a cell and is concerned with the storage of the cell’s hereditary material or DNA.

• It regulates cellular functions such as metabolism, growth, protein synthesis, and cell division. It determines how and when cells differentiate.

• This organelle is common in both plants and animals. Thus this is wrong.

• They are highly organised dynamic layers present outside protoplasm just below the cell wall in plant cells and are referred to as plasma membranes.

• The plasma membrane or cell membrane is selectively permeable and acts as a barrier by maintaining the difference in concentration of ions and molecules between the inside and outside of the cells.

• These biological membranes form defining boundaries of a cell creating a distinct interior and exterior reference for a cell.

• The cell membranes are asymmetric, dynamic and fluid in nature. Membrane fluidity is crucial to its functions.

• Most proteins and lipids molecules are able to move freely within the membrane. It is composed of lipids, proteins, and carbohydrates.

• This is common to both plants and animals. Thus this option is wrong.

• Chloroplasts are double membrane-bound cell organelles. These heterogeneous structures are the chlorophyll-containing green-coloured plastids that perform photosynthesis in plants.

• Since animals are incapable of performing photosynthesis they do not possess chloroplasts (Plastid) in their cells. Thus it is the correct option.

Hence among the following options, option 3. Chloroplast is the most appropriate answer.
