A cell uses this to break down glucose during cellular respiration.
What is oxygen?
Throughout the cytoplasm of the eukaryotic cells.
What is the cytoskeleton?
The arrangement of parts of an organism or an object.
What is the structure?
A group of organs that work together to perform body functions.
What is an organ system.
Plants make their own food during photosynthesis. In what group do plants belong?
What is Producers?
The process of breaking down food to produce ATP.
What is Cellular Respiration?
Even when it is cold outside, the human body maintains an internal temperature of 37 °C. Which term describes the maintenance of a stable internal condition?
What is homeostasis?
The process in which a cell divides and forms two identical nuclei.
What is Mitosis?
Molecules that make up proteins.
What are amino acids?
A system of membranes near the nucleus.
What is the endoplasmic reticulum?
A plant cell has this as evidence it is NOT an animal cell.
What is the cell wall?
The organelle that takes proteins by putting together a chain of amino acids using the coding from the cell's DNA.
What is ribosomes?
The two methods of moving particles in passive transport are?
What is diffusion and osmosis.
Some organisms consist of one cell. Other organisms consist of multiple cells. Which of the following is true of cells in a multicellular organism?
Different types of cells have different functions.
During photosynthesis, green pigments capture energy from the sunlight. What is this material called?
What is chlorophyll?
This part of the cell is unique to eukaryotic cells.
What is a nucleus?
Which one of the following substances must animal cells take in from the environment to maintain homeostasis?
What is oxygen?
The movement of particles in and out of the cell without energy is called.
What is passive transport.
This term describes the adaptation of cells, organs, or organ systems for a specific function.
What is specialization?
Cellular respiration occurs in this organelle.
What is the mitochondrion?
This is the difference between eukaryotic cells and prokaryotic cells.
What is membrane-bound organelles?
Which molecule is a source of energy, a store of energy in the body and can mix with water?
What is a carbohydrate?
Cells often need to move materials across the cell membrane from areas low concentration into areas of higher concentration. This is the opposite direction of passive transport.
What is active transport?
