QuestionAnswer
What are the main differences between prokaryotic and eukaryotic cells in IGCSE Biology? Prokaryotic cells lack a nucleus and membrane-bound organelles, are generally smaller, and have a simple structure, while eukaryotic cells have a nucleus, membrane-bound organelles, and are more complex. Examples include bacteria (prokaryotic) and plant/animal cells (eukaryotic).
How does photosynthesis occur in plant cells? Photosynthesis occurs in the chloroplasts of plant cells, where light energy is converted into chemical energy. Carbon dioxide and water are used to produce glucose and oxygen, with the overall process summarized as 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
What are enzymes, and how do they function in biological processes? Enzymes are biological catalysts that speed up chemical reactions by lowering activation energy. They are specific to particular substrates and work best within certain temperature and pH ranges to facilitate processes like digestion and DNA replication.
Explain the role of the circulatory system in humans. The circulatory system transports oxygen, nutrients, hormones, and waste products throughout the body. The heart acts as a pump, and blood vessels (arteries, veins, capillaries) carry blood to and from tissues, helping maintain homeostasis.
What are the functions of the different parts of a leaf in photosynthesis? The blade of the leaf captures light energy, the palisade mesophyll contains chloroplasts for photosynthesis, the spongy mesophyll allows gas exchange, and the stomata regulate the entry of carbon dioxide and exit of oxygen and water vapor.
How do enzymes denature, and what are the consequences? Enzymes denature when exposed to high temperatures, extreme pH, or chemicals, causing their shape to change and losing their ability to catalyze reactions. This can halt essential biological processes and affect organism health.
What is osmosis, and why is it important in plant cells? Osmosis is the diffusion of water across a semi-permeable membrane from a region of lower solute concentration to higher solute concentration. It maintains turgor pressure in plant cells, providing structural support and stability.
Describe the process of cell division in IGCSE Biology. Cell division occurs through mitosis, where a parent cell divides to produce two genetically identical daughter cells. This process is essential for growth, repair, and asexual reproduction in multicellular organisms.
