Chapter 4: A Tour of the Cell Vocab

What is Cell theory

• The Theory that cells are made of atoms
• The theory that cells are made of elements
• The theory that all living things are composed of cells and that all cells come from other cells.
• The theory that all living things are made from atoms

What is the cell wall

• A protective layer external to the plasma membrane in animal cells, bacteria, fungi, and some protists; protects the cell and helps maintain its shape.
• A protective layer external to the plasma membrane in plant cells, bacteria, fungi, and some protists; protects the cell and helps maintain its shape.
• A protective layer external to the plasma membrane in plant cells, bacteria, fungi, animal and some protists; protects the cell and helps maintain its shape.
• A protective layer external to the plasma membrane in plant cells; protects the cell and helps maintain its shape.

What is the central vacuole

• In a plant cell, a large membranous sac with diverse roles in growth and the storage of chemicals and wastes.
• In all cells, a large membranous sac with diverse roles in growth and the storage of chemicals and wastes.
• In a plant cell, a collection of small membranous sacs with diverse roles in growth and the storage of chemicals and wastes.
• the center of a cell

What is a centriole

• A structure in an animal cell composed of cylinders of microtubule triplets
• A structure in an animal cell composed of cylinders of microfilament triplets
• A structure in an animal cell composed of cylinders of microtubule pairs
• A structure in an animal cell composed of cylinders of microfilament pairs

What is chloroplast

• An organelle found in animals that photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic molecules (sugars) from carbon dioxide and water.
• An organelle found in plants and photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic molecules (sugars) from carbon dioxide and hydrogen
• An organelle found in plants and photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic molecules (sugars) from carbon dioxide and water.
• An organelle found in plants and photosynthetic protists that absorbs sunlight and uses it to drive the synthesis of organic molecules (sugars) from carbon monoxide and water.

What is the Cytoplasm

• The contents of a eukaryotic cell between the plasma membrane and central vacuole; consists of a semifluid medium and organelles
• The contents of a eukaryotic cell between the plasma membrane and the nucleus; consists of a semifluid medium and organelles
• the fluid mosaic model 
• the name of Mr. Joske's fish

What is the Endoplasmic reticulum

• An extensive membranous network in a eukaryotic cell, continuous with the outer nuclear membrane and composed of ribosome-studded (rough) and ribosome-free (smooth) regions.
• The thinnest of the three main kinds of protein fibers making up the cytoskeleton of a eukaryotic cell; a solid, helical rod composed of the globular protein actin.
• A structure within the nucleus where ribosomal RNA is made and assembled with proteins imported from the cytoplasm to make ribosomal subunits.
• A digestive organelle in eukaryotic cells; contains hydrolytic enzymes that digest engulfed food or damaged organelles.

What is a flagella

• A long cellular appendage specialized for locomotion
• A transmembrane protein that interconnects that extracellular matrix and the cytoskeleton.
• A protein with one of more short chains of sugars attached to it.
• A dense region of DNA in a prokaryotic cell.
