Parts of the Cell
The simplest and smallest living thing that exists
What is a cell?
Cells take molecules from the environment and transform them into energy
What is nutrition?
The condensed, x-shaped version of chromatin
What is a chromosome?
An older, basic cell with no nucleus
What is a prokaryotic cell?
Cell division in which the parent cell produces 2 identical daughter cells
What is mitosis?
Powerhouse of the cell, organelle that is the site of ATP (energy) production
What is a mitochondria?
A cell's ability to communicate with the external environment
What is interaction?
Chromosomes that have the same sequence of genes and the same structure
What is a homologous chromosome?
More complex cells that have their genetic material in the nucleus
What is a eukaryotic cell?
Cell division that produces reproductive cells that are not identical
What is meiosis?
The organelle where photosynthesis occurs
What is a chloroplast?
The formation of new cells from existing ones
What is reproduction?
A loose combination of DNA and proteins in the nucleus
What is chromatin?
Any cell of a living organism other than the reproductive cells
What is a somatic cell?
Area where the chromatids of a chromosome are attached
What is a centromere?
An organelle that aids in cell division, located on opposite poles in the cell
What is a centriole?
Division of the cytoplasm at the end of mitosis
What is cytokinesis?
One half of a duplicated chromosome
What is a chromatid?
Reproductive cells which have only half the number of chromosomes as body cells
What is a gamete?
Protein fibers that appear between both poles of the cell during mitosis
What is a mitotic spindle?
Fluid inside the nucleus
What is nucleoplasm?
A genetic exchange between pairs of chromosomes
What is genetic recombination?
The protein found with genetic material in the nucleus
What is a histone?
A rapid and uncontrolled growth of cells
What is cancer?
An extension of the cytoplasm, "false feet"
What is pseudopodia?
