Cell Structure and Function — Chapter Summary

The cell theory states that all

The cell theory states that all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cell

Prokaryotic cells lack a well

Prokaryotic cells lack a well-defined nucleus and membrane-bound organelles, while eukaryotic cells have both. Bacteria are prokaryotes, whereas plant

Plant cells have a rigid cell

Plant cells have a rigid cell wall, large vacuoles, and chloroplasts for photosynthesis, while animal cells lack a cell wall and chloroplasts but have

Each organelle performs a specific function

Each organelle performs a specific function: mitochondria produce energy (ATP), chloroplasts perform photosynthesis, the nucleus stores genetic materi

The plasma membrane is selectively permeable

The plasma membrane is selectively permeable and controls the movement of substances in and out of the cell through diffusion, osmosis, endocytosis, a
