Homeostasis and Cell Processes

What is the process of cellular respiration?

• Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

• Cellular respiration is the process of converting sunlight into chemical energy.

• Cellular respiration is the breakdown of proteins into amino acids for energy.

• Cellular respiration is the process of photosynthesis in plants.

What are endocytosis and exocytosis?

• Endocytosis is the process of taking substances into a cell, while exocytosis is the process of expelling substances from a cell.

• Endocytosis is the process of expelling substances from a cell, while exocytosis is the process of taking substances into a cell.

• Endocytosis and exocytosis are both processes that occur only in plant cells.

• Endocytosis is a type of cellular respiration, while exocytosis is a type of photosynthesis.

What are the ingredients of photosynthesis?

• Oxygen and glucose

• Carbon dioxide and water

• Nitrogen and sunlight

• Hydrogen and minerals

What is the significance of maintaining homeostasis?

• It allows organisms to grow larger and stronger.

• It ensures optimal conditions for cellular functions.

• It helps organisms to reproduce more quickly.

• It enables organisms to adapt to any environment.

What is diffusion?

• The movement of particles from an area of higher concentration to an area of lower concentration.

• The process of particles moving randomly in all directions.

• The mixing of two substances to form a homogeneous solution.

• The separation of particles based on size or mass.

What role does chlorophyll play in photosynthesis?

• Chlorophyll is the pigment that absorbs sunlight, allowing plants to convert carbon dioxide and water into glucose and oxygen.

• Chlorophyll is responsible for the color of the soil in which plants grow.

• Chlorophyll helps in the respiration process of plants by releasing carbon dioxide.

• Chlorophyll is a type of carbohydrate that provides energy to plants.

What is the difference between active and passive transport?

• Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

• Active transport occurs only in plant cells, while passive transport occurs in animal cells.

• Active transport is a slower process than passive transport.

• Active transport can only move substances with the concentration gradient, while passive transport can move against it.

What is osmosis?

• The movement of solutes from an area of low concentration to an area of high concentration.

• The diffusion of water through a semi-permeable membrane.

• The process of active transport in cells.

• The absorption of nutrients in the intestines.

What is the function of ATP in living organisms?

• ATP is a genetic material that stores information.

• ATP provides energy for cellular processes.

• ATP is a type of protein that aids in digestion.

• ATP helps in the transport of oxygen in the blood.

What is a semi-permeable membrane?

• A membrane that allows all substances to pass through freely.

• A membrane that allows certain substances to pass through while blocking others.

• A membrane that is impermeable to all substances.

• A membrane that only allows gases to pass through.
