Question

Which of the following statements is true about the plant cell?
A. The cytoplasm is filled up with the nucleus.
B. The cytoplasm is a jelly-like mixture of cellulose.
C. Plant cells contain a rigid cell wall made up of cellulose.
D. There are plenty of chloroplast granules in plant root cells.

Answer 1

Plant cells are eukaryotic cells that differ from other eukaryotic creatures in numerous basic ways. Plant and animal cells both include nuclei and organelles that are comparable. The existence of a cell wall outside the cell membrane is one of the distinguishing features of a plant cell.

Complete answer:
Plant cells are rectangular and bigger than animal cells. Even though plant and animal cells are both eukaryotic and share a few cell organelles, plant cells perform different activities than animal cells.
Option A: The cytoplasm is filled up with nucleus: Except for the cell nucleus, the cytoplasm is all of the material within a eukaryotic cell that is contained by the cell membrane. The nucleoplasm is the substance inside the nucleus that is enclosed within the nuclear membrane. So, this is not a true statement.
Option B: The cytoplasm is a jelly-like mixture of cellulose: Cytoplasm is a transparent, gel-like material found on the exterior of the nucleus but inside the cell membrane. It's mainly made up of water, with some enzymes, organelles, minerals, and organic molecules thrown in for good measure. When cytoplasm is disturbed or agitated, it liquefies. It's commonly referred to as cytosol, which means "cell material." So, this is not a true statement.
Option C: Plant cells contain a rigid cell wall made up of cellulose: Cell wall composition varies by species and may be affected by cell type and developmental stage. The polysaccharides cellulose, hemicelluloses, and pectin make up the main cell wall of terrestrial plants. Other polymers including lignin, suberin, and cutin are frequently attached or incorporated in plant cell walls. So, this is a true statement.
Option D: There are plenty of chloroplast granules in plant root cells: Although root hairs' purpose is to gather water and nutrients, they are thought to lack chloroplasts. They don't go through the process of photosynthesis. Remember that, like mitochondria, chloroplasts have their DNA. Photosynthetic roots are roots that can perform photosynthesis.

Thus, the answer is option C: Plant cells contain a rigid cell wall made up of cellulose.

Note:
In animal cells and certain lower plant cells, centrioles are a component of the centrosome that is situated near the nucleus. However, it is not found in higher plants. During cell division, it is involved in the production of spindle fiber.
