Cell structure and organization

• nucleus - contains the genetic material (DNA) that controls cell activities
• Nucleolus - A small dense body within the nucleus where ribosomal RNA molecules are synthesized.
• ribosomes - sites of protein synthesis
• mitochondria - site of aerobic respiration
• mitochondria - organelles responsible for producing energy through respiration
• cytoplasm - jelly-like substance inside the cell membrane, where most chemical reactions take place
• ribosomes - sites of protein synthesis within cells
• Golgi apparatus - Modifies and packages proteins and lipids produced by the endoplasmic reticulum.
• Endoplasmic reticulum - A network of membranes involved in protein synthesis and lipid metabolism.
• Ribosomes - The site of protein synthesis, made up of rRNA and proteins.
• cytoplasm - fluid substance inside the plasma membrane, containing organelles such as mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, peroxisomes, cytoskeleton, and vesicles
• mitochondrion - site of aerobic respiration; produces energy-rich molecule ATP from glucose
• endoplasmic reticulum - membrane-bound organelle involved in lipid and protein synthesis, transport, and storage
• endoplasmic reticulum - network of flattened sacs called cisternae; involved in protein synthesis and lipid metabolism
• smooth endoplasmic reticulum - lacks ribosomes
• rough endoplasmic reticulum - studded with ribosomes
• chloroplasts - organelle found only in plant cells, contain chlorophyll which is used to capture sunlight during photosynthesis
• vacuole - large fluid-filled sac that stores water, nutrients, waste products, pigments, and enzymes
• endoplasmic reticulum - network of flattened sacs called cisternae which is involved in the production of proteins and lipids
• cell wall - provides support and protection to the cell
• endoplasmic reticulum (ER) - network of flattened sacs that produce proteins and lipids
• rough endoplasmic reticulum - studded with ribosomes, involved in protein synthesis
• Vacuole - Stores water, nutrients, and wastes.
• smooth endoplasmic reticulum - not studded with ribosomes, involved in lipid metabolism
• Golgi apparatus - modifies and packages proteins produced by ER
• lysosome - contains digestive enzymes to break down waste materials
• Nucleus - The control center of the cell containing genetic material (DNA).
• mitochondrion - double membrane-bound organelle that produces energy through aerobic respiration
• rough ER - studded with ribosomes, involved in protein synthesis
• Vacuole - Stores water, nutrients, and wastes, maintains turgor pressure to keep plant cells rigid.
• Cell wall - Provides structural support and protection to the cell, composed of cellulose or chitin depending on the type of organism.
• endoplasmic reticulum (ER) - network of flattened sacs or tubules involved in protein synthesis and lipid metabolism
• endoplasmic reticulum (ER) - network of flattened sacs that extends throughout cytoplasm; involved in protein synthesis and lipid metabolism
• golgi apparatus - modifies and packages proteins and lipids produced by ER; forms secretory vesicles
• golgi apparatus - modifies and packages proteins and lipids produced by the endoplasmic reticulum
• ribosome - site of protein synthesis, composed of ribosomal RNA (rRNA) and proteins
• rough ER - studded with ribosomes that produce proteins to be packaged into vesicles or exported out of the cell
• smooth ER - lacks ribosomes but is involved in detoxification processes and lipid biosynthesis
• golgi apparatus - modifies and packages proteins produced by rough ER, sorts them for delivery within the cell or outside it
• golgi apparatus - modifies, packages, and transports proteins to their final destinations within or outside the cell
