Study Notes
Cell Organelles and Structures Summary
- Lysosomes are saccules containing enzymes that break down cellular debris and foreign material.
- Mitochondria are the powerhouses of the cell, producing energy in the form of ATP.
- Chloroplasts, found in plant cells, carry out photosynthesis, converting light energy into chemical energy.
- Peroxisomes contain enzymes that break down hydrogen peroxide and other reactive oxygen species.
- The cytoskeleton is a network of filaments providing support and structure to the cell.
- Prokaryotic cells lack a true nucleus or organelles, and have genetic material in the cytoplasm.
- The plasma membrane is a selectively permeable barrier composed of a phospholipid bilayer.
- The cell wall, composed of cellulose, provides support and protection to plant cells.
- Mitochondria produce ATP, chloroplasts carry out photosynthesis, and peroxisomes break down hydrogen peroxide.
- The cytoskeleton is composed of actin filaments, intermediate filaments, and microtubules, involved in cell movement and division.
- Actin filaments, the thinnest of the three types of filaments, are involved in cell movement, shape, and division.
- The cytoskeleton is also involved in cell movement, cell shape, and cell division.
