Cell Structure and Organelles
This is a central body in most cells, and it is dense and holds the genetic make-up of the cell.
What is a nucleus?
This is the diffusion of water across a permeable membrane.
What is osmosis?
This is the phase of cell's life cycle when it reproduces itself.
What is cell division?
These are small molecules that escort specific amino acids to the ribosomes.
What is transfer RNA?
This is a primary tissue, and the functions include support, storage, and protection.
What is connective tissue?
This is the substance of a cell, but not the nucleus.
What is cytoplasm?
When compared to the fluid in a cell, this has a high solute concentration and a low water concentration.
What is a hypertonic solution?
This is the division of the cell nucleus.
What is mitosis?
These are long strands that carry the exact information of the DNA to the ribosome for protein synthesis.
What is messenger RNA?
This function of this tissue is to respond to stimuli.
What is nervous tissue?
They are tiny, dark structures, and their main job is to be the site for protein synthesis.
What are ribosomes?
This has the same water concentration and solute concentration as body cells.
What is an isotonic solution?
This is the first stage of mitosis where the nucleus temporarily breaks down.
What is prophase?
These are components of the ribosomes that are in the cytoplasm and assist with protein synthesis.
What is ribosomal RNA?
This type of tissue is able to contract and create a force that will cause movement.
What is muscle tissue?
These are the called the "powerhouses" of the cell because they make most of the cell's ATP.
What are mitochondria?
This has fewer solutes and more water than the fluid inside the cell.
What is a hypotonic solution?
These are one copy of the DNA after it is replicated paired with another copy of the DNA.
What are chromatids?
This is the first stage of protein synthesis where the cell makes a working copy of the messenger RNA.
What is transcription?
This type of tissue forms the boundaries between the body and the external environment.
What is epithelial tissue?
These are a system of tunnels that twist through the cytoplasm and carry proteins and other substances from one side of the cell to the other.
What are the endplasmic reticulum?
This is permeable and keeps some substances out, while allowing others in, and it protects the contents of the cell.
What is membrane transport?
This is a button-like body holding sister chromatids together.
What is the centromere?
This is the second stage of protein synthesis where the "language" of the nucleic acids are changed into the "language" of the proteins.
What is translation?
This happens when the damaged tissue is replaced by the same type of cells.
What is regeneration?
