SNC2D1: Plant
and Animal Cells
(p. 29-32 of the textbook.)
The three postulates of the cell theory state:
1._____________________________________________________________________________
2._____________________________________________________________________________
3._____________________________________________________________________________
Cells are divided into two types:
no nucleus
eg.
has nucleus
eg.

major ones are shown in the diagrams below.

Structures ONLY in Plant Cells
Description/Function
Found outside the cell membrane, a _____________ but ____________ structure made of
__________________.
Provides support and __________________.
Same as in the animal cell, but plant cells have only __________, ___________ vacuole.
Water content inside the vacuole has a large
effect on ___________ pressure.
 Contain _____________________, which absorb ___________________ which is used in the process of

ANIMAL CELL
Structures in Plant AND Animal Cells
Description/Function
 Mostly _______________, fills the interior of the cell.
 _________________ take place here.
 Consistency can change from _____________ to _________, allowing organelles to move around.
Cell Membrane
Nucleus
Mitochondria
Endoplasmic
Reticulum
Golgi Bodies
Vacuoles
Surrounds the cell with a flexible, __________________ membrane. Supports the cell and allows some
substances (like _____________ and ___________) to pass through while preventing others (like
_________________). Thus, the membrane is called _________________________.
 Roughly spherical, contains all the ____________________ information and controls all
_________________. (Cell’s “brain”).
 Information is stored in ________________ which contain DNA.
 “Powerhouse” of cell.
 Make _____________ available to the cell by carrying out the process of ________________.
Equation:
 ________________ cells or ______________ cells have many mitochondria, while ______ cells have
very few.
 A 3-dimensional network of _________________________ and ____________, connecting the
_______________ membrane to the ______________ membrane.
 It ___________________ materials through the cell.
 In the brain, ER assists with the production and secretion of ________________, and in muscle cells is
involved with __________________________________.
 They collect and process materials to be _________________ form the cell.
 They also make and secrete ____________.
 Cells lining the ______________ have many Golgi bodies.
 Consist of single ___________________ enclosing fluid.
 Basically a “_______________ area” with additional functions, such as: ________________
substances, _______________ substances, mainting internal pressure (____________).
 Animal cells have ___________, __________ vacuoles.
