Cell Processes Power Point
SLIDE 1
1. Cell Processes—how cells obtain _____________________ and get rid of ___________________.
SLIDE 2
2. Diffusion is the movement of particles from an area of _____________ concentration to an area of
____________________ concentration. E_____________________is not needed for diffusion.
3. ______________________ is the special name for the diffusion of _________________________. It has a
different name because the diffusion of water is so _____________________________. Cells ________ _________
need energy for osmosis.
SLIDE 3
4. Passive transport is the diffusion of ________________ __________________through the membrane.
Particles move from ________________ to _______________ concentration. The cell does not need _________________
for passive transport.
5. _____________________ transport is the movement of particles against the flow of ____________________________.
Particles are moved from an area of LOW concentration to an area of ___________________ concentration.
________________________ is required for this process to occur.
SLIDE 4
6. In moving large particles, endocytosis is where the cell __________________ surrounds a particle and forms
a ______________________ around it and brings it ______________ the cell. The prefix endo means ________________.
7. In exocytosis, vesicles form at the _________ or _______________ ____________________ and carry the particle to
the cell membrane to be released. The prefix _______________ means ‘out of’.
SLIDE 5
8. Photosynthesis is the process where plants capture ____________________ energy and convert it to
______________________(food). During photosynthesis, energy is _______________________ in food. Photosynthesis
begins with ___________________ and __________________ ____________________ and the end products are ____________
and oxygen. Photosynthesis occurs only in cells with _________________________________.
9. In cellular respiration, __________________________ is released from food ____________________. Energy is
________________________ from food. Cellular respiration begins with ____________________ and oxygen and ends
with _____________________ and carbon dioxide. Cellular respiration occurs in all cells.
SLIDE 6
10. Fermentation is the process of ___________________ being broken down by enzymes without using
_______________________. One type of fermentation is when you feel _______________________ in your muscles due
to the production of lactic acid. Another type of fermentation occurs in some bacteria and yeast.
SLIDE 7
11. ___________________ fission is the process of ____________________________ reproduction in which one cell
____________________ to form two identical cells. Most _________________________ reproduce in this way.
SLIDE 8
12. Mitosis is the complicated process of ___________________ separation. Each new cell gets a copy of
_______________ ___________________________.
13. ________________________ is cell division that produces new ___________ _______________ with ________________ the
number of chromosomes. Sex cells are __________________________.
SLIDE10
14. The prefix ‘hyper’ means ___________________________. Hypertonic refers to when there is more solute
(salt)_______________________ of the cell. The cell will then __________________________ because the water in the cell
will flow _________________.
SLIDE 11
15. The prefix ‘_____________’ means ‘under’. Hypotonic means that there is less _______________ on the
________________________ of the cell. The water will flow _____________________ the cell, and the cell will
__________________________.
SLIDE 12
16. An __________________________ solution is balanced. There is the same solute on the outside of the cell as
the ____________________________. They neither gain nor lose ___________________ through osmosis.
