4c.
All organisms are made up of one or more cells.
The cell is the basic unit of organization in organisms.
All cells come from cells.
5. The movement of substances through the cell membrane without the use of
energy.
6.
diffusion
Osmosis
Facilitated diffusion
7a.
7b.
diffusion
When particles move from high to low concentrations
8.
to reach equilibrium – where there are the same # of particles outside as
inside the cell
9.
the diffusion of water through a cell membrane
10.
Molecules can move into/out of cell with the help of a transport protein.
11.
When energy is used to move materials across the cell membrane – 2 types
are endocytosis (into) and exocytosis (out of)
12.
Endocytosis – into the cell
Exocytosis – out of the cell
Both deal with moving large particles
13.
process in which the nucleus divides to form two identical nuclei – happens
in body cells
14.
Stages of mitosis – IPMAT
Interphase – chromosomes duplicate
Prophase – chromatid pairs visible and spindle fibers form
Metaphase – chromatid pairs line up in center (MIDDLE) of cell
Anaphase – chromatids separate
Telophase – cytoplasm separates
Last Phase – Cytokinesis – two new cells are formed
15.
two new nuclei that are identical to each other and the original nucleus
16.
Cell division producing haploid sex cells
Different because two divisions of the nucleus occur – like mitosis x2.
Deals with sex cells – egg and sperm
Also, know the following:
