what two types of cells are there | prokaryotic and eukaryotic |
A two phase process that reproduces eukaryotic cells are | the interphase and mitotic |
what are the four phases of Mitosis | Prophase, metaphase, anaphase, telophase |
what is the term for division of cells | meiosis |
in the prokaryotic cells, what is the process in which the cells divide | binary fission |
how are the eukaryotic cells divided | mitosis |
what 3 things do the interphase cells do | stockpile needed materials, copy dna, make new organelles |
what makes up the largest group of pathogens | bacteria |
what bacteria lives within us or on us | normal flora |
what must enter another cell and "hijack" the cells parts, energy supply, and materials to do all cellular activity | viruses |
what is a one-celled animal like organism that can be found in water | protozoa |
what enzyme is missing in people with PKU | phenylalanine |
the cells all work together to allow for proper functioning of the processes necessary for life . what are they | digestion, respiration, reproduction, movement, and heat and energy |
what acts as a protective covering in order for the cell to maintain integrity and survive | cytoplasma |
what contains specialized structures to help regulate the movement of things in and out of the cell | selective permeable |
what are the two transport methods of cells | passive, and active |
passive transport can be divided into four types, what are they | diffusion, osmosis, filtered, and facilitated diffusion |
what is it called when a substance of higher concentration moves into a lower concentration | diffusion |
what is the middle ground between two concentrations | concentration gradient |
what is it called when a substance moves from a lower concentration to a higher concentration | osmosis |
what is it called when a substance is forced across a membrane due to high pressure | filtration |
a transport protein that gets help moving across a membrane is | facilitated diffusion |
