Common to Both Animal and Plant Cells
* Cell Membrane: This thin, flexible barrier controls what enters and leaves the cell.
* Cytoplasm: A gel-like substance that fills the cell and contains organelles.
* Ribosomes: Tiny structures that manufacture proteins.
* Nucleus: The control center of the cell, containing DNA (genetic material).
* Nucleolus: A structure within the nucleus that produces ribosomes.
* Endoplasmic Reticulum (ER): A network of membranes involved in protein and lipid synthesis, and detoxification.
* Golgi Apparatus: Processes, packages, and distributes proteins and other molecules.
* Mitochondria: The "powerhouse" of the cell, responsible for energy production (ATP).
* Lysosomes: Contain enzymes that break down waste products and cellular debris.
Unique to Plant Cells
* Cell Wall: A rigid outer layer that provides support and protection. Made primarily of cellulose.
* Chloroplasts: Organelles containing chlorophyll, which capture sunlight for photosynthesis.
* Central Vacuole: A large, fluid-filled sac that stores water, nutrients, and waste products. It also helps maintain cell shape.
* Plasmodesmata: Small channels that connect adjacent plant cells, allowing for communication and transport.
Unique to Animal Cells
* Centrioles: Small, cylindrical structures involved in cell division (specifically, forming spindle fibers).
* Lysosomes: While animal and plant cells both have lysosomes, those in animal cells are more prominent and play a larger role in breaking down materials.
* Cilia and Flagella: Hair-like projections that help with movement (cilia are shorter and more numerous, flagella are longer and fewer).
Key Differences to Remember
* Shape: Plant cells are generally rectangular or boxy due to their cell walls. Animal cells are more diverse in shape.
* Energy Production: Plant cells can create their own energy through photosynthesis, while animal cells rely on consuming food for energy.
