Cell Theory
This is the smallest unit of life.
What are cells?
This organelle is the control center of the cell, containing DNA.
What is the nucleus?
Cell division is important for these three key processes.
What are growth, repair, and reproduction?
This is the first stage of mitosis where chromosomes condense and spindle fibers form.
What is prophase?
DNA stands for this long name.
What is deoxyribonucleic acid?
The 3 parts of the cell theory include.
What are all living organisms are made up of one or more cells?
What are cells can only arise from pre-existing cells?
What are cell is the basic unit of structure and function in living things?
Plant cells have this rigid structure outside their membrane, while animal cells do not.
What is the cell wall?
These organisms reproduce asexually by dividing into two genetically identical cells.
What are prokaryotes / bacteria?
In this stage of mitosis, chromosomes align in the middle of the cell.
What is metaphase?
DNA has this famous shape.
What is a double helix?
This organelle has its own DNA signalling that its ancestors originated outside of the cell.
What is the mitochondria?
These two organelles are involved in energy conversion, with one performing photosynthesis and the other cellular respiration.
What are chloroplasts and mitochondria?
This is the name of the process where damaged cells are repaired or replaced through cell division.
What is mitosis?
In this phase, sister chromatids are pulled apart to opposite sides of the cell.
What is anaphase?
The four nitrogenous bases in DNA are adenine, thymine, guanine, and this one.
What is cytosine?
These cells can become any type of specialized cell.
Name one feature shared by plant and animal cells and one feature that differs.
What are shared features like the nucleus and differing features like chloroplasts (plant) and centrioles (animal)?
This type of reproduction, requiring two parent cells, ensures genetic diversity.
What is sexual reproduction?
Name the phase that marks the end of mitosis, where two nuclei form.
What is telophase?
During DNA replication, nucleotide base pairs always pair together in a specific way. Which base pair together?
What is (A) Adenine with (T) Thymine and (C) Cytosine with (G) Guanine?
Cell theory applies to both types of cells: prokaryotic and eukaryotic. The primary structural difference between them is the presence of this organelle in eukaryotes.
What is the Nucleus?
This organelle is responsible for packaging proteins and lipids into vesicles for transport within the cell or to the cell membrane.
What is the Golgi apparatus?
This process, which occurs at the end of mitosis or meiosis, physically divides the cytoplasm into two daughter cells.
What is cytokinesis?
This is the stage outside of mitosis when the cell is performing normal functions and preparing for division.
What is interphase?
A change in the DNA sequence that can lead to a genetic disorder or variation in traits is called this.
What is a mutation?
