Cell Membrane Structure: A phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates. Function: Regulates the movement of substances in and out of the cell; maintains homeostasis. Relation of Structure to Function: The fluidity of the bilayer allows for selective permeability, enabling transport proteins to facilitate specific molecule passage. Type of Cell: Found in all cell types (prokaryotic and eukaryotic). Link to Ecosystem Survival: The cell membrane's selective permeability is crucial for nutrient uptake and waste removal, affecting organism health and, consequently, ecosystem balance. Ribosomes Structure: Composed of ribosomal RNA (rRNA) and proteins; can be free-floating or attached to the rough ER. Function: Site of protein synthesis. Relation of Structure to Function: Ribosomes' two subunits come together during protein synthesis, effectively translating mRNA into polypeptides. Type of Cell: Found in all cell types (prokaryotic and eukaryotic). Link to Ecosystem Survival: Protein synthesis is essential for cell function and organism development, influencing biodiversity and ecosystem dynamics. Rough ER Structure: A network of membranes studded with ribosomes. Function: Synthesizes and modifies proteins for secretion or for use in the cell membrane. Relation of Structure to Function: The ribosomes on its surface allow for simultaneous protein synthesis and modification. Type of Cell: Found primarily in eukaryotic cells, especially in secretory cells. Link to Ecosystem Survival: Protein production is vital for cellular function and overall organism health, impacting food webs. Smooth ER Structure: A network of membranes without ribosomes. Function: Synthesizes lipids, metabolizes carbohydrates, and detoxifies drugs. Relation of Structure to Function: Its smooth structure allows for lipid synthesis and processing without interference from ribosomes. Type of Cell: Found in eukaryotic cells, particularly in liver cells and steroid hormone-producing cells. Link to Ecosystem Survival: Lipid synthesis supports cellular membranes, essential for cell integrity across ecosystems. Vesicles/Vacuoles Structure: Membrane-bound sacs that can vary in size. Function: Transport materials within the cell (vesicles) or store substances (vacuoles). Relation of Structure to Function: Their membrane allows for the isolation and transport of various substances. Type of Cell: Present in eukaryotic cells; larger vacuoles are typical in plant cells. Link to Ecosystem Survival: Storage of nutrients and waste contributes to cellular health, influencing plant growth and stability in ecosystems. Lysosome Structure: Membrane-bound organelles containing digestive enzymes. Function: Breaks down waste materials and cellular debris. Relation of Structure to Function: The acidic environment and enzymes facilitate the breakdown of complex molecules. Type of Cell: Found in eukaryotic cells, especially in animal cells. Link to Ecosystem Survival: Waste breakdown is essential for recycling nutrients, maintaining ecosystem health. Mitochondria Structure: Double-membraned organelle with an inner membrane folded into cristae. Function: Produces ATP through cellular respiration. Relation of Structure to Function: The large surface area of the cristae increases ATP production efficiency. Type of Cell: Found in eukaryotic cells. Link to Ecosystem Survival: ATP production is vital for cellular processes, impacting energy flow through ecosystems. Chloroplast Structure: Double-membraned organelle containing thylakoids stacked in grana. Function: Conducts photosynthesis to convert light energy into chemical energy. Relation of Structure to Function: Thylakoid membranes house chlorophyll, maximizing light capture. Type of Cell: Found in plant cells and some protists. Link to Ecosystem Survival: Photosynthesis supports food chains, providing energy for nearly all ecosystems. Golgi Apparatus Structure: Stacked, membrane-bound sacs (cisternae). Function: Modifies, sorts, and packages proteins and lipids for secretion or delivery. Relation of Structure to Function: The stacked arrangement facilitates efficient processing and transport. Type of Cell: Found in eukaryotic cells. Link to Ecosystem Survival: Proper protein and lipid delivery is crucial for cellular function and organismal health. Cytoplasm Structure: Gel-like substance inside the cell membrane, excluding the nucleus. Function: Provides a medium for biochemical reactions and houses organelles. Relation of Structure to Function: The fluid nature allows for the movement of materials and organelles. Type of Cell: Found in all cell types. Link to Ecosystem Survival: Supports cellular functions critical for organism survival, impacting overall ecosystem dynamics. Cytoskeleton Structure: A network of protein filaments and tubules. Function: Provides structural support, facilitates cell movement, and aids in intracellular transport. Relation of Structure to Function: The dynamic nature allows for flexibility and adaptation in cell shape and movement. Type of Cell: Present in eukaryotic cells. Link to Ecosystem Survival: Structural integrity and mobility support organism survival, affecting population dynamics. General Comparison and Significance Function Comparison to the Nucleus: While the nucleus houses genetic material and controls cell activities, organelles like mitochondria and ribosomes are essential for energy production and protein synthesis. Importance of Each Organelle: Each organelle plays a unique role that supports the overall function of the cell. For example, without mitochondria, cells cannot produce ATP efficiently, which would compromise all cellular activities. Contributions to the Cell: Each organelle contributes uniquely to the cell's overall functionality. For instance, lysosomes handle waste, while the Golgi apparatus ensures proper protein delivery. Other organelles cannot replace these functions due to their specialized structures and roles. These notes should help you study effectively for your AP Biology exam!
