Responses
cell membrane
cell membrane
chloroplast
chloroplast
cell wall
cell wall
ribosome
ribosome
The correct answer is cell wall.
The organelle that provides structure and rigidity to a plant cell is the cell wall.
The organelle that provides structure and rigidity to a plant cell is the cell wall. To arrive at the correct answer, you can examine the given options and their descriptions.
1. Cell membrane: The cell membrane is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell. It does not provide structure and rigidity to a plant cell.
2. Chloroplast: Chloroplasts are responsible for photosynthesis, the process by which plants convert light energy into chemical energy. While chloroplasts are found in plant cells, their function is related to energy production, not structural support.
3. Cell wall: The cell wall is a rigid layer that surrounds the cell membrane in plant cells (and some other organisms). It provides strength, protection, and a framework for the cell to maintain its shape. This is the correct answer.
4. Ribosome: Ribosomes are responsible for protein synthesis. Though important for cell function, they are not involved in providing structure or rigidity to a plant cell.
Based on the descriptions of the organelles provided, the cell wall is the organelle that provides structure and rigidity to a plant cell.
