1. "A" is a food particle which is being engulfed by phagocytosis "B" forming a food vacuole "D". "C" is the cell membrane. "E" is a lysosome with hydrolytic enzymes formed by the Golgi Body. The lysosome will combine with the food vacuole and digest the macromolecules inside. "F" is a worn out mitochondrion which will also be degraded by lysosomes. "H" and "I" are endoplasmic reticulum, rough and smooth which will bud off to form the Golgi Body.

2. A = outer membrane
D = stroma thylakoids
B = inner membrane
E = granum
C = grana thylakoids
Stroma is the liquid phase inside the plastid(not labeled)

3.
A = large vacuole; large vacuoles are common in plant
cells and small vacuoles
are common in
animal cells
B = chloroplast; found only in plant cells
C = cytoplasm with free floating ribosomes
D = Endoplasmic Reticulum - Rough - ribosomes attached
E = Nucleolus
F = Nucleus
G = Endoplasmic Reticulum - Rough - ribosomes
attached
H = Mitochondrion
I = cell wall primary - outside
cell wall
J = cell wall secondary - cell
wall formed as the cell matures
K = Golgi Body
L = Endoplasmic Reticulum - Smooth -
no ribosomes attached

4. The correct answer is "d". Chloroplasts contain chlorophyll which
absorbs light needed for the process of photosynthesis. These are
found only in selective plant cells.

5. The correct answer is "b". Mitochondria are found in all eukaryote
cells (plants and animal) where they carry ut the process of cellular
respiration.

17. The correct answer is "b". All cell types (prokaryote and eukaryote)
contain DNA (may be in different forms) and ribosomes.

21. The correct answer is "c". Remember that mitochondria and plastids
are semiautonomous. This means that they are capable of self replication,
contain their own DNA with its genome, and have their own ribosomes
which are use for protein synthesis. The DNA in present in a circular
form similar to that of the prokaryotes. Read the section in you text concerning
the evolution of chloroplast and mitochondria. pp 94-94
