Cell Processes and Organization

Homeostasis

• In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.

• The maintenance of a constant internal state in a changing environment

• group of organs that work together to perform a specific function

• The process by which cells use oxygen to produce energy from food.

Photosynthesis

• The movement of particles from regions of higher concentration to regions of lower concentration.

• process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food.

• The process by which cells use oxygen to produce energy from food.

Cellular Respiration

• The maintenance of a constant internal state in a changing environment

• The movement of particles from regions of higher concentration to regions of lower concentration.

• process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food.

• The process by which cells use oxygen to produce energy from food.

Mitosis

• In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.

• The process by which cells use oxygen to produce energy from food.

• process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food.

• The maintenance of a constant internal state in a changing environment

Passive Transport

• In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.

• The process by which cells use oxygen to produce energy from food.

• process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to make food.

• The movement of substances across a cell membrane without the use of energy by the cell.

Diffusion

• The movement of substances across a cell membrane without the use of energy by the cell.

• In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.

• The movement of particles from regions of higher concentration to regions of lower concentration.

• The process by which cells use oxygen to produce energy from food.

Osmosis

• The diffusion of water through a semipermeable membrane.

• The movement of substances across a cell membrane without the use of energy by the cell.

• In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.

• The maintenance of a constant internal state in a changing environment

Active Transport

• The maintenance of a constant internal state in a changing environment

• The movement of substances across a cell membrane without the use of energy by the cell.

• A group of similar cells that perform the same function.

• The movement of substances across the cell membrane that requires the cell to use energy.

Endocytosis

• The movement of substances across a cell membrane without the use of energy by the cell.

• The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell.

• A group of similar cells that perform the same function.

• The maintenance of a constant internal state in a changing environment

Exocytosis

• The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell.

• The process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane to release the particle.

• The maintenance of a constant internal state in a changing environment

• The movement of particles from regions of higher concentration to regions of lower concentration.
