Structure & functional differences of plant and
animal cells

Review: p.129 Self Quiz and
Challenge question #1
ISP CD tour of plant and
animal cells
I. Review
questions
Cells
of true multicellular organisms can become specialized.
Today, I'd like to consider HOW cells become specialized.
First,
we need to understand how a "typical" cell is constructed,
and then examine how changing the components will change the
cell.
II.
Lightning tour through the cell
With your group, briefly
review the function of each of the major organelles,
the components that make up
cells. Some are found in both plant and animal cells, while
others are found in only one or the other.
<discussion>
Let's
briefly highlight the most important function of each.
A. Barrier
- plasma membrane
B. Information storage
and processing
1. Nucleus
2. Ribosomes
C. Energy
1. Mitochondria
2. Chloroplasts
D. Internal membranes
1. Endoplasmic
reticulum
2. Golgi
3. lysosomes
E. Shape, strength and
movement
1. Vacuole
2. Cytoskeleton
3. Centriole
4. Cilia and
flagella
Organelle
study guide
Q. How
do changes in the relative composition of organelles change
the function of the cell? In other words, how do cells
become specialized?
