Sci 7 Cell Centers (Mr. D's class)

What are organelles?

• Molecules that carry genetic information

• tiny structures inside a cell; they have specific jobs that allow the cell to function

• Proteins found in the cytoplasm

• Types of cell membrane

What is the main difference between plant and animal cells? (In other words, what does a plant cell have that animals lack?)

• Presence of mitochondria

• Ability to reproduce

• Presence of a nucleus

• Presence of a cell wall

What is mitosis?

• A process of photosynthesis

• A type of bacteria

• A type of protein

• One parent cell creates 2 identical daughter cells

What is osmosis?

• water moves from an area of higher concentration to an area of less concentration of a cell

• movement of water through a cell membrane

• neither of these

What is diffusion?

• The movement of particles due to gravity.

• The movement of particles from one state of matter to another.

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

• The movement of water, food, waste from an area of high concentration to an area of low concentration

What is photosynthesis?

• The process by which plants absorb water from the soil

• The process by which plants release chloroplasts into the atmosphere

• The process by which plants convert carbon dioxide into nitrogen to make food

• The process by which green plants use water, sunlight, and carbon dioxide to make energy and sugar (food)

Which organelle is responsible for photosynthesis in plant cells?

• Nucleus

• Mitochondria

• Chloroplast

• Ribosome

What is respiration?

• sugars are broken down to release energy from food

• happens in the mitochondria

• Lysosome

• Golgi Apparatus

What is the function of a cell wall?

• Energy production for the cell

• Cell communication

• Waste removal from the cell

• Support and protection for the cell

What is the function of a nucleus?

• Generate energy for the cell

• Control cell division

• Produce proteins

• "boss" of the cell; controls all cell activities
