Cell Structure
This jellylike material holds all the organelles inside the cell.
What is cytoplasm?
The process by which plants use sunlight to make food.
What is photosynthesis?
This organelle is found only in plant cells and allows photosynthesis.
What is the chloroplast?
The cell membrane is described as this type of barrier.
What is selectively permeable?
This theory states that all living things are made of cells.
What is the Cell Theory?
This organelle controls all cell activities and contains DNA.
What is the nucleus?
The process cells use to release energy from glucose.
What is cellular respiration?
This structure provides shape and support for plant cells but not animal cells.
What is the cell wall?
Molecules naturally spread out evenly through this process.
What is diffusion?
Cells come from these, according to Cell Theory.
What are preexisting cells?
These tiny structures build proteins inside the cell.
What are ribosomes?
Molecules move from high to low concentration during this process.
What is diffusion?
This type of cell has a large central vacuole.
What is a plant cell?
Water moves across a membrane through this process.
What is osmosis?
The molecule that stores energy for the cell’s activities
What is ATP?
This organelle produces energy by breaking down food into ATP.
What are mitochondria?
Water moves across a selectively permeable membrane in this process.
What is osmosis?
This type of cell does not have chloroplasts.
What is an animal cell?
Moving molecules from low to high concentration requires this.
What is energy (ATP)?
This condition means maintaining a stable internal environment.
What is homeostasis?
This large sac in plant cells stores water and nutrients.
What is the vacuole?
This process requires energy to move materials against the concentration gradient.
What is active transport?
These two organelles are unique to plant cells.
What are the cell wall and chloroplasts?
The process that uses ATP to move materials into or out of the cell.
What is active transport?
Proteins that speed up chemical reactions in cells.
What are enzymes?
