This structure is the largest organelle in animal cells and is the control center of the cell
What is the nucleus?
100
A structure which functions to control what enters and leaves the cell
What is the Cell Membrane?
100
An object possessed by a eukaryotic cell, but not a prokaryotic cell.
What is the nucleus? (Or What is a membrane-bound organelle?)
100
The stage of mitosis during which the chromosomes line up along the equator of the cell.
What is metaphase?
100
The loose combination of DNA and proteins in a cell nucleus
What is chromatin?
200
This structure produces proteins for the cell
What is a ribosome?
200
A method of cell transport which allows especially large molecules to move into the cell across the membrane
What is a endocytosis?
200
This structure is present in a plant cell, but not in an animal cell
What is a chloroplast? (Or: What is a cell wall?)
200
The phase of the cell cycle during which the cytoplasm divides to form two new cells.
What is cytokinesis?
200
The central region of a chromosome, which connects the two sister chromatids.
What is the centromere?
300
This organelle is the site of photosynthesis
What is a chloroplast?
300
The movement of water across a semi-permeable membrane
What is osmosis?
300
A cell in this type of environment will lose water and, therefore, shrivel.
What is hypertonic?
300
The phase of mitosis during which the sister chromatids separate simultaneously
What is anaphase?
300
The two pieces of a chromosome which contain the same genes in the same order (but not necessarily with the same alleles); they are connected by the centromere
What are sister chromatids?
400
This organelle breaks down worn-out cell parts
What is a lysosome?
400
A structure which allows large molecules to pass through the cell membrane in process called facilitated diffusion
What is a transport protein?
400
A cell in this type of environment will lose water at the same rate as it gains water, and will therefore not change its shape/size.
What is an isotonic solution?
400
The phase of mitosis during which the nucleus prepares for division, condensing chromatin into chromosomes and breaking down the nuclear envelope.
What is prophase?
400
The smallest object on this list: chromosome, nucleus, cell, DNA, nucleotide
What is a nucleotide?
500
This structure is made up of layers of folded membranes, studded with ribosomes, and helps to create proteins.
What is the rough endoplasmic reticulum?
500
A method of cell transport that moves molecules from low to high concentrations AND requires energy
What is active transport?
500
This method of cell transport involves moving particles from high concentration to low concentration via a transport protein.
What is facilitated diffusion?
500
The stage of mitosis during which the nuclear envelope begins to re-form and the chromosomes to unravel
What is telophase?
500
The phase during which the cell replicates its DNA.
