Parts of the Nucleus
100
Controls Entry into and out of cell
What is Plasma Membrane
100
The cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division). Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible. The cell may contain a pair of centrioles (or microtubule organizing centers in plants) both of which are organizational sites for microtubules.
What is Interphase
100
Any substance that can't be broken down in simpler substances.
What is an Element
100
Structures suspended within the cytoplasm that perform specific functions for the cell
What are organelles
100
The fluid content of the nucleus.
What is Nucleoplasm
200
Shapes and supports a cell
What is Cell wall
200
Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nucleolus disappears. Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle.
What is Prophase
200
When two or more elements combine chemically they form?
What is a compound.
200
Organelles responsible for proteins synthesis
What is Ribosomes
200
The dense region in the nucleus that is the site of RNA synthesis.
What is Nucleolus
300
Traps light and is used to produce food for plants
What is Chlorophyll
300
The nuclear membrane dissolves, marking the beginning of prometaphase. Proteins attach to the centromeres creating the kinetochores. Microtubules attach at the kinetochores and the chromosomes begin moving.
What is Prometaphase
300
Protein molecules are made up of smaller molecules called
What is Amino acid
300
An intracellular vesicle containing digestive enzymes.
What is Lysosomes
300
Surrounding the nucleus and separating it from the cytoplasm is a?
What is Nuclear envelope
400
Power house of a cell
What is Mitochondria
400
Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate. This organization helps to ensure that in the next phase, when the chromosomes are separated, each new nucleus will receive one copy of each chromosome.
What is Metaphase
400
A network of membraneous of channels in the cytoplasm of a cell that functions in intracellular transport
What is Endoplasmic reticulum
400
Receive information about conditions and activities in other parts of the cell chemical information.
What is nuclear pores
500
Stores food or contains pigment
What is Plasmid
500
The paired chromosomes separate at the kinetochores and move to opposite sides of the cell. Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
What is Anaphase
500
The nucleoplasm contains the?
What is Nuclear Matrix
