1. Use the diagram of a plant cell on the previous page to become familiar
with the features of a plant cell. Use your knowledge to label the ten
structures in the transmission electron micrograph of the cell.
Use the following list of terms to help you: Nuclear membrane, cytoplasm,
endoplasmic reticulum, mitochondrion, starch granule, nucleus, vacuole,
plasma membrane, cell membrane
a. Cell membrane
b. Nucleus
c. Vacuoles
d. mitochondria
e. Endoplasmic reticulum
f. Nuclear membrane
g. Plasma membrame
h. Starch granule
i. cytoplasm
2.
a. Which features identify this plant cell as eukaryotic?
Plants have eukaryotic cells with large central vacuoles, cell walls
containing cellulose, and plastids such as chloroplasts and chromoplasts.
b. You can’t do b.
Well you can’t just do it.
c. What is an organelle?
Organelles are specialized structures that perform various jobs inside cells.
d. Why are there so many different types of organelles in
eukaryotic cells (e.g. plant and animal cells)?
Different organelles play different roles in the cell — for instance, mitochondria generate
energy from food molecules; lysosomes break down and recycle organelles and macromolecules; and the
endoplasmic reticulum helps build membranes and transport proteins throughout the cell
e. Name the organelle where photosynthesis occurs:
Chloroplasts

f. How many of these organelles are present in the labeled cell
above?
Plant cells have three organelles not found in animal cells. They include the cell wall, large
central vacuole, and plastids
