Living or Nonliving?
This is the basic unit of structure and function in all living things.
What is a cell?
This organelle is known as the control center because it contains DNA.
What is the nucleus?
This type of transport moves particles from high concentration to low concentration without ATP.
What is passive transport?
This process produces two genetically identical daughter cells for growth and repair.
What is mitosis?
This type of biological molecule is a protein that speeds up chemical reactions in cells.
What is enzyme?
This scientist named the tiny compartments he saw in cork 'cells.'
Who is Robert Hooke?
This organelle modifies, sorts, and packages proteins.
What is the Golgi apparatus?
This is the movement of water across a selectively permeable membrane.
What is osmosis?
During this stage, chromosomes line up across the middle of the cell.
What is metaphase?
The part of an enzyme where the substrate attaches is called this.
What is active site?
A rock is considered nonliving because it is not made of these.
What are cells?
These structures build proteins by linking amino acids together.
What are ribosomes?
In this solution, water leaves an animal cell and the cell shrinks.
What is a hypertonic solution?
This is the process in which unspecialized cells become specialized for specific jobs.
What is cell differentiation?
The substance an enzyme acts on is called this.
What is substrate?
A virus has genetic material, but it cannot do this independently.
What is reproduce?
This organelle produces most of a cell's usable ATP during cellular respiration.
What is the mitochondrion?
This process uses energy to move substances from low concentration to high concentration.
What is active transport?
Name the asexual reproduction process in which one cell copies its DNA and splits into two cells.
What is binary fission?
Enzymes help reactions happen faster by lowering this amount of energy needed to start a reaction.
What is Activation energy?
Name at least four characteristics that scientists use to identify living things.
Possible answers: made of cells, use energy, grow and develop, respond to stimuli, reproduce, maintain homeostasis, contain genetic material, and evolve.
Prokaryotic cells and eukaryotic cells have some similar structures. Which structure below do both cell types have?
A. centrioles B.mitochondria
C.lysosomes D.cytoplasm
What is D. Cytoplasm
The sodium-potassium pump moves how many sodium ions out and how many potassium ions in during each cycle?
Three sodium ions out and two potassium ions in.
Explain why daughter cells produced through asexual reproduction usually have the same DNA as the parent cell.
The parent copies its DNA before division, and each daughter cell receives an identical copy. There is no mixing of genetic material from two parents.
Name TWO factors that can change an enzyme’s activity.
What is temperature, pH, or substrate concentration?
