Cell Structure
This is the chromosome-containing organelle of a eukaryotic cell.
What is the nucleus?
This organelle is essentially a membrane-enclosed bag of hydrolytic enzymes
What is the lysosome?
This is how DNA exists when the cell is not dividing. It is made up of DNA plus proteins.
What is chromatin?
This organelle functions as the site of protein synthesis.
What are ribosomes?
This organelle is known as the "powerhouse of the cell."
What is the mitochondrion?
This is a membrane-enclosed sac taking up most of the interior of a plant cell.
What is the central vacuole?
In plant cells, this large structure stores water and provides turgor pressure to maintain cell rigidity.
What is the central vacuole?
These are used as guide tubes for movement of materials, for separation of chromosomes during cell division, and for maintaining the shape of cells by assuming a compression-resisting role.
What are microtubules?
This is a short cellular appendage specialized for locomotion.
What is a cilia?
This structure is the bouncer of the cell, deciding who gets in and who stays out.
What is the cell membrane?
This is an organelle found in plants that absorbs sunlight and uses it to drive synthesis of organic compounds.
What is the chloroplast?
This jelly-like goo fills the cell and keeps things from crashing into each other.
What is the cytoplasm?
These are used in muscle contraction, cell motility, and for resisting pulling forces in the maintenance of cell shape.
What are microfilaments (actin filaments)?
This is where metabolism of carbohydrates and detoxification of drugs occur.
What is the smooth endoplasmic reticulum (smooth ER)?
These tiny sacs are the cell’s garbage disposals, breaking down waste with enzymes.
What are lysosomes?
This is an extensive membranous network in eukaryotic cells that is composed of ribosome-studded and ribosome-free regions.
What is the endoplasmic reticulum (ER)?
This organelle contains enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide.
What is the peroxisome?
These help maintain the shape of the cell by bearing tension (resisting pulling forces) and are made up of a diverse family of proteins.
What are intermediate filaments?
This organelle is like the CEO’s office, where DNA is stored and decisions are made.
What is the nucleus?
This subatomic particle has a positive charge and hangs out in the nucleus.
What is a proton?
This organelle serves as the site of cellular respiration
What is the mitochondrion?
This organelle consists of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum.
What is the Golgi apparatus?
This is made up of a phospholipid bilayer and is the outer boundary of an animal cell.
What is the plasma membrane?
This cellular highway is where proteins are made and folded — sometimes it’s “rough,” sometimes it’s “smooth.”
This cellular highway is where proteins are made and folded — sometimes it’s “rough,” sometimes it’s “smooth.”
When atoms bond by sharing electrons, they form this type of bond.
What is a covalent bond?
