1. Why do plant cells have cell walls and animal cells don’t?
PLANTS NEED CELL WALLS FOR ADDED SUPPORT
(TALL TREES and NOT BURSTING WHEN FULL OF WATER)
ANIMAL CELLS NEED TO BE FLEXIBLE (MOVEMENT)
+1
2. Why do plant cells have large vacuoles and animal cells don’t?
PLANTS NEED TO BE ABLE TO STORE FOOD and
WATER (NO LEAVES IN THE WINTER, GROUND FROZEN)
+1
3. Why do plant cells have chloroplasts and animal cells don’t?
PLANTS NEED TO MAKE THEIR OWN FOOD
(AUTOTROPHS)
ANIMALS CONSUME THEIR FOOD (HETEROTROPHS)
+1
4. Did all the cells you observe have a cell membrane?
YES!! +1
Explain
ALL CELLS HAVE A CELL MEMBRANE +1
5. What is the function of the cell membrane?
GIVES THE CELL STRUCTURE or SHAPE +1
AND
REGULATES WHAT ENTERS AND EXITS THE CELL
+1
6. What is found in leucoplasts of potato cells?
STARCH
+1
How do you know?
THE IODINE TURNED THE LEUCOPLASTS A
DARK PURPLISH BLACK COLOR
+1
7. What is found in the chromoplasts of peppers?
PIGMENT/COLOR
+1
8. Where are stomata located on plants?
UNDERSIDE OF LEAVES
or
EPIDERMAL LAYER (EPIDERMIS)
or
CUTICLE
+1
9. What do stomata do for plants?
GAS EXCHANGE – ALLOWS CO2 IN AND O2 OUT
(respiration)
+1
10. Now that we have looked at both plant cells and animal cells, name
the main differences between plant and animal cells?
PLANTS HAVE:
a] LARGE VACUOLES +1
b] CELL WALLS +1
c] CHLOROPLASTS +1
