chlorophyll
B. Plasma Membrane –
Controls entrance &
exits
C. Cell Wall – 3 layers
D. Cytoplasm – Liquid in
cell
E. Vacuole – Store water

Respiration
G. Nucleus - Genetics
**Four elements of the cell
structure:
A.
B.
C.
D.
Cell wall
Plasma membrane
Cytoplasma
Nucleus
Cell Wall Structure
Too little water in vacuole…..
Tobacco flower losing pigment
because lack of mitochondria
proteins
2. What are 2 function of PM?
a) Control entrance & exit into and
out of cell
b) Relays environmental
information about condition
3. What are 3 organelles……
1) Mitochondria – Control Chemical
Reactions, site of respiration
2) Plastids – Contain Chloroplasts;
contain chromoplasts (red,
yellow, brown pigments)
3) Vacuoles – store water, dissolve
minerals
4. What are 3 func. of nucleus..
A. Control Physiological
Characteristics
B. Control Appearance of Plant
C. Passes Characteristics to
Offspring
5. What are 2 types tissue….
1) Meristem
2) Permanent
6. What are differences……
Meristem actively divides to form
new growth where permanent
does not actively divide
7. What are 3 types meristems..
1) Apical – plant length
2) Cambium – plant diameter
3) Intercalary Zone – stem height
**Cambium Meristem

Intercalary Zone Meristem
8. What two types permanent…
1) Epidermis – outside covering
2) Vascular System –
transportation system of plant
a) Xylem - Up
b) Phloem - Down
