Cell Vocabulary
Structures that perform specific functions within a cell
Organelle
The organelle which directs the cells activity and contains the cells operating instructions and stores information that will be passed along to new cells
Nucleus
The diffusion of water across a cell membrane
Osmosis
What is the name of the man who first discovered cells?
Robert Hooke
A network of folded membranes that serves as the cells transportation system and helps it make proteins and other substances needed by the cell
Endoplasmic Reticulum
An organelle that contain fluid and that store water and nutrients and helps cells digest food
Vacuole
The movement of a substance from an area of its higher concentration to an area of its lower concentration
Diffusion
Name the two cell organelles that aren't listen in your book but we discussed.
Golgi Bodi
Nucleolus
A structure that converts the chemical energy of food into a form that the cell can use
Mitochondria
An organelle that maintains the internal environment of the cell it allows food to exit
Cell Membrane
The process in which the cell nucleus divides during the production of two cells with identical DNA
Mitosis
What is the difference between diffusion and osmosis?
Diffusion = the movement of a substance from an area of high concentration to a lower are of concentration.
Osmosis= the diffusion of water.
The organelle that begin the process of making proteins
Ribosomes
_____________ is the fluid substance containing the organelles it lies between the nucleus and the cell membrane
Cytoplasm
Structure in the nucleus made up of long thread like DNA coils is called ____________
Chromosome
What are the three main differences between an animal cell and plant cell?
Cell Wall
Chloroplast
Plant Cells Have Large Vacuoles
Name all the 8 parts of animal cell that as stated in your book.
Nucleus
Mitochondria
Endoplasmic Reticulum
Nucleus
Vacuole
Ribosomes
Cell Membrane
Cytoplasm
Lysosomes
____________ contains a powerful chemical that breakdown harmful molecules and recycle worn out cell parts
Lysosome
Structure that performs a specific function within a cell.
Organelle
Name the steps of Mitosis.
1) Cells get ready to divide.
2a) Mitosis begins.
2b) Pairs of chromosomes line up at the center of the cell.
2c) Each pair of chromosomes separate moving to opposites ends of the cells.
2d) Chromosomes become chromatin, new cell forms around each nucleus, and mitosis is complete.
3) Cytoplasm divides forming to identical cells.
