Study Notes
Cell Structure and Function
- Cell membrane (Structure 4): Provides rigid support for the cell.
- Mitochondria: Produce ATP (adenosine triphosphate) for protein synthesis.
- Ribosomes: Synthesize proteins.
- Vacuoles: Store materials in single-celled organisms.
- Digestive enzymes: Synthesized in structure 3 of a cell.
- ATP synthesis: Occurs in structure A of a cell.
- Passage of materials into and out of the cell: Occurs through structure C of a cell.
- Oxygen production: Occurs in structure D of a cell.
- Excretion of cellular wastes: Occurs through structure C of a cell.
- DNA storage: Primarily contained in the nucleus of a plant cell.
- Information transfer for protein production: Passes from the nucleus to ribosomes.
- Excretion: Associated with structure A of a cell.
- Organelle: A structure that performs a specialized function within a cell.
- Protein synthesis: Primarily occurs in structure B of a cell.
- Plant cell storage of organic acid wastes: Occurs in structure B of a cell.
- Metabolic process associated with the organelle: Aerobic respiration.
- Structures found in every living cell: A plasma membrane and cytoplasm.
- Plant cell identification: The presence of a cell wall (structure E) and chloroplasts (structure F) differentiates a plant cell from an animal cell.
- Levels of organization in humans: Levels of organization increase in complexity from molecules to organelles, tissues, organs, and organ systems.
- Groups of cells with similar function: Form tissues.
- Sequence of increasing complexity: Organelles, cells, tissues, organs, organism.
- Similarity between humans and multicellular animals: Both are composed of organ systems.
- Order of organization in complex organisms: Cells, tissues, organs, systems.
- Protein synthesis location: Proteins are synthesized in ribosomes.
- Mitochondrial diseases: Cause fatigue and weakness as mitochondria are responsible for ATP production, which is essential for energy.
- Mitochondria in heart muscle cells: Heart muscle cells contain a higher proportion of mitochondria than skin cells because they require more energy to contract.
- Organelle function: The organelle in the diagram represents a chloroplast, where photosynthesis takes place. This process converts light energy into chemical energy (glucose), which is essential for survival.
- Plant cell structure not found in animal cells: A cell wall.
- Cell structure's role in homeostasis: Structure 1 (cell membrane) regulates the passage of substances into and out of the cell, maintaining a stable internal environment. It is associated with the movement of water and dissolved substances. The cell membrane interacts with structure 3 (cytoplasm) to maintain homeostasis.
- Organelle X function: Organelle X represents a chloroplast, where photosynthesis takes place. It converts light energy, water, and carbon dioxide into glucose and oxygen. Glucose is the energy source for the organism, while oxygen is released into the atmosphere.
- Order of complexity from least to most complex: Cell, organelle, tissue, organ, organism.
- Process carried out in cell Y but not in cell X: Photosynthesis.
- Function of lettered parts in the diagram: The specific letter must be chosen for this response to provide a complete answer.
