Cell Definitions
The basic unit of all living things, basic building blocks of life.
What is a cell?
The control center of the cell that acts like a brain. It contains DNA that determines everything about the cell.
What is the nucleus?
This is only found in plant cells and it gives the plant structure and support.
What is a cell wall?
The number of vacuoles in a plant cell and animal cell.
What is one for a plant cell and more than 1 in an animal cell?
Organisms composed of only one cell (Ex. Bacteria).
What are unicellular organisms?
Parts of a cell that help it function, tiny organs that have a specific job.
What are organelles?
The jelly-like substance inside the cell where the organelles are found.
What is the cytoplasm?
The job of the golgi apparatus.
What is the post office of the cell that takes proteins, packages them, and sends them where they need to go?
A rectangular shaped cell that contains a cell wall, chloroplast and one large vacuole.
What is a plant cell?
The definition of multicellular organisms.
What is an organism made up of many cells?
An organelle that puts together proteins for the cell.
What are ribosomes?
The thin, flexible barrier surrounding the cell, protects the cell and controls what goes in and out.
What is the cell membrane?
The job of the mitochondria.
What is the powerhouse of a cell. This organelle is where sugar is used to produce energy and turns food into energy?
Green substance in the chloroplasts that traps energy from sunlight.
What is chlorophyll?
An instrument used that helps one to see cells.
What is a microscope?
Instructions that tell the cell what to do.
What is DNA?
The tough, nonliving material that acts like an outside skeleton for each plant cell.
What is a cell wall?
The job of the endoplasmic reticulum.
What is a transportation network that forms a maze of passageways in which proteins, molecules, and other materials are carried from one part of the cell to another?
The process by which plants make their own food (sugar) using carbon dioxide, water and sunlight.
What is photosynthesis?
Amoeba, bacteria and paramecium are examples of this type of organism.
What are examples of unicellular organisms?
Theory stating that the cell is the basic unit of all living organisms and only living cells can produce new living cells.
What is the cell theory?
This is where fluids and other nutrients are stored for the cell. It is like a reservoir, a storage tank that holds water or other materials.
What is the vacuole?
The job of the lysosome.
What is an organelle that is like the trash and recycling center of a cell. It helps the cell get rid of waste?
Organelle where photosynthesis takes place.
What is chloroplast?
The 4 levels of organization.
What are cells, tissues, organs, and organ systems?
