The difference between Plant,Animal,And Bacterial Cells?
Plant cells have chloroplasts and cell walls Bacterial cells have a cell membrane and ribosomes DO NOT contain a nucleus or other organells
What cell organelles are involved in each process?
Chloroplasts and mitochondria
What is Chromotain?
Contains instructions to direct the function of a cell
The Cell Theory?
1)All living things are composed of cells 2) Cells are the basic unit of structure and function in living things 3) All cells are produced from other cells
The difference between passive and active transport. Name the two types of Passive Transport
Passive Transport- 2 types 1)diffusion- molecules move from an area of higher concentration to lower concentration 2) Osmosis-Water molecules move from an area of higher concentration to lower concentration Active Transport- Requires the cell to use energy to move molecules across the cell membrane
The difference between Permeable Membrane and an impermeable Membrane and Semipermeable Membranw
Permeable Membrane- The cell membrane allows molecules to pass into the cell Impermeable Membrane-Does not allow molecules Semipermeable-some smaller molecules can pass through the cell membrane but larger molecules can not.
The three stages of the cell cycle
Interphase - the cell grows to its mature size makes a copy of its DNA, and prepares to divide into two cells Mitosis - one copy of the DNA is distributed into each of the two daughter cells Cytokinesis - the cytoplasm divides distributing the organelles into each of the two new cells
Four stages with Mitosis
Prophase - the chromatin in the nucleus condenses to form chromosomes, spindle fibers form a bridge between the ends of the cell Metaphase- The chromosomes line up across the center of the cell Anaphase- The centromes split Telephase-
