Cell Structure
The chromosome-containing organelle of a eukaryotic cell.
What is the nucleus?
An extensive membranous network in eukaryotic cells that is composed of ribosome-studded and ribosome-free regions.
What is the ER?
Plants have a plasma membrane, which is surrounded by this.
What is the cell wall?
This is how DNA exists when the cell is not dividing. It is made up of DNA + proteins.
What is chromatin?
The membrane-enclosed sac taking up most of the interior of a plant cell.
What is the central vacuole?
In plants, these structures allow movement of cytoplasm from one cell to another.
What is plasmodesmata?
This is made up of a phospholipid bilayer and is the outer boundary of an animal cell.
What is the cell membrane?
An organelle found in plants that absorbs sunlight and uses it to drive synthesis of organic compounds.
What is chloroplast?
This organelle contains enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen.
What are peroxisomes?
These connections provide cytoplasmic channels between adjacent animal cells.
This organelle functions as the site of protein synthesis.
What are ribosomes?
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 formed when plasma membranes of neighboring cells in a layer are fused, forming a barrier that prevents leakage of extracellular fluid across the layer.
What is a tight junction?
These are used in muscle contraction, cell motility, and for resisting pulling forces in the maintenance of cell shape.
What are microfilaments?
This organelle is essentially a membrane-enclosed bag of hydrolytic enzymes.
What is a lysosome?
A young plant cell first secretes a relatively thin and flexible wall that is called this.
What is the primary cell wall?
These are used as guide tubes for movement of materials, separation of chromosomes during cell division, and for maintaining the shape of cells by assuming a compression-resisting role.
What are microtubules?
