|
What is a Cytoskeleton?
|
It's the cytoplasmic network of protein filaments and tubes that plays an essential role in cell movement, shape, and division.
|
|
|
What is the double membrane that surrounds the nucleus of a eukaryotic cell called?
|
Nuclear envelope.
|
|
|
Define Chromosome.
|
Chromosomes are one of the structures in the nucleus of a eukaryotic cell that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA.
|
|
|
What is the cell organelle that helps make and package materials to be transported out of the cell?
|
That is the Golgi Complex.
|
|
|
What are Mitochondria?
|
Mitochondria are the cell organelle that are the site of cellular respiration, which produce ATP.
|
|
|
Where can Ribosomes be found?
|
Ribosomes can be found on the rough ER and just floating inside the cell.
|
|
|
Define Centriole.
|
It's an organelle that is composed of two short microtubules at right angles to each other and that has an active role in mitosis.
|
|
|
What is the soluble portion of the cytoplasm, which includes molecules and small particles, such as ribosomes, but not the organelles covered with membranes?
|
That would be Cytosol.
|
|
|
Cytoplasm?
|
It's the region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus.
|
|
|
What are one of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function?
|
An Organelle.
|
|
|
What is a cell?
|
In biology, the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm. There are two types: Animal and Plant cells.
|
|
|
What is a cell composed of RNA and protein (the size of protein synthesis) called?
|
Ribosome.
|
|
|
What are Lysosomes?
|
A cell organelle that contains digestive enzymes and that buds from the Golgi apparatus.
|
|
|
What is a system of membranes in a cell's cytoplasm and that assists in the production, processing, and transport of proteins?
|
Endoplasmic Reticulum (ER)
|
|
|
What is a central vacuole?
|
In some protists and in most plant cells, a large, fluid-filled organelle that stores water, enzymes, metabolic wastes, and other materials.
|
|
|
What is an organelle found in plant and algae cells where photosynthesis occurs?
|
Chloroplast.
|
|
|
What is the plasma membrane of a cell?
|
It's the cell membrane, the cell's outer boundary.
|
|
|
In a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction.
|
The Nucleus.
|
|
|
What is the nucleolus?
|
It's the part of the eukaryotic nucleus where ribosomal RNA is synthesized.
|
|
|
What is a rigid structure that surrounds the cell membrane and provides support to the cell (found in plant cells)?
|
Cell Wall.
