Plant cells
1. a. Chloroplasts carry out photosynthesis.
b. Conducting cells carry transport water and
nutrients.
c. Root hair cells absorb water from the soil.
d. The cell membrane controls the opening and
shutting of the stomata.
2.Organelles are the parts of a plant cell each with a
specific function.
3. a. The function of the nucleus is to control all
chemical reactions in the cell and how the cell develops
and reproduces.
b. The function of the cell wall is to be rigid enough to
support the plant.
c. The function of the chloroplasts is to trap the light’s
energy needed for photosynthesis.
4. The purpose of the chlorophyll is to trap light energy
needed for photosynthesis.
5. a. The cell that is “hairy” is root hair cell.
b. The cell that is called the “gatekeeper” is the cell
membrane.
c. The cell that is called “the transporter” is the
conducting cell.
6. a. The clue “I’m green” is referring to the substance
chlorophyll. Its job is to trap light energy needed for
photosynthesis.
b. The clue “I‘m found in a cell wall” is referring to a
material called cellulose. Its job is to the cell wall hard
to support the plant.
c. The clue “I’m found in a vacuole” is referring to sap.
Sap carries nutrients through the plant.
7. a. The reactants in photosynthesis are carbon
dioxide and water.
b. The main product of photosynthesis is glucose and
oxygen.
c. The name of the sugar that is used by plants as
food is called glucose.
d. Sunlight provides the energy for photosynthesis.
8. a. If a plant didn’t have guard cells it would lose all of
its water.
b. If a plant didn’t have cellulose, the cell wall would
collapse because it would be too weak to support the
plant.
c. If a plant did not have chlorophyll it could not
engage in photosynthesis.
9. a. Most plants are green because they contain
chlorophyll.
b. Plant cells have thicker walls the animal cells
because plants do not have bones to support them.
c. Photosynthetic cells are found on the top of leaves
because the sun shines from above. The light from the
sun provides the energy for photosynthesis.
d. Plants have two different types of conducting
cells. The first type carries nutrients to various parts of
the plant, and the second type transports water.
10. There are more types of animal cells than plant
cells because animals tend to have a more complex
biological structure than plants.
11. Animals don’t need to carry out photosynthesis
because they get their energy to grow from eating food.
