This part of the cell contains DNA and controls cell functions.
What is the nucleus?
This type of tissue covers the surface of your body and lines internal organs.
What is epithelial tissue?
This is the smallest unit of life in all living organisms.
What is a cell?
An organelle that every cell must have.
What is a cell membrane?
This term refers to the outer layer of a plant cell that gives it structure and support.
What is the cell wall?
This gel-like substance inside the cell holds the organelles in place. Also, chemical reactions take place there.
What is the cytoplasm?
This tissue type helps to move parts of your body and maintain posture.
What is muscle tissue?
A group of similar cells that work together to perform a specific function.
What is a tissue?
An organelle that protects itself, and its contents, with a double-membrane that can only be bypassed through "pores."
What is the Nucleus?
This organelle stores water, nutrients, and waste in plant cells.
What is the vacuole?
Known as the "powerhouse" of the cell, this organelle produces energy.
What is the mitochondria?
This tissue is responsible for transmitting electrical signals throughout the body.
What is nervous tissue?
Two or more tissues that work together to perform a specific function form this.
What is an organ?
An organelle that utilizes oxygen (O2) to efficiently break down sugars via cellular respiration.
What is a mitochondria?
This type of cell lacks a nucleus and is typically smaller than eukaryotic cells.
What is a prokaryotic cell?
An organelle that can produce transmembrane proteins destined for the plasma membrane.
What is the Rough Endoplasmic Reticulum?
A tissue primarily composed of collagen, which requires vitamin C for biosynthesis,
What is connective tissue?
An organ system that allows an organism to respond to its environment.
What is the Nervous System?
An organelle that produces the organelle that makes protein.
What is the Nucleolus?
A molecule that is a temporary copy of genetic material, capable of moving out of the Nucleus.
What is messenger Ribonucleic Acid (mRNA)?
An organelle that uses carbon dioxide and photons to build organic molecules.
What is a chloroplast?
A tissue that has special ion channels on its membrane that prevent it from undergoing a "spasm."
What is Cardiac Tissue?
A system that not only carries oxygen and nutrients to cells, but also takes away waste and CO2 produced by them.
What is the Circulatory System?
An organelle that uses mRNA and amino acids (attached to tRNA) to synthesize polypeptides in the cytoplasm.
What is a ribosome?
This pigment evolved its color specifically for earth's atmosphere and solar output.
What is Chlorophyll?
