There are two basic types of cells….
PLANT CELLS
LESSON OBJECTIVES
1. Label and identify the major
structures that make up a
typical plant cell.
2. Describe what these structures
do.
3. Name and describe how 2
specialised plant cells are
adapted for their job.

Plant Cells
•
Cell wall made of cellulose which
strengthens the cell and gives it support.
• Chloroplasts, found in all the green parts
of the plant. They are green because they
contain chlorophyll. They absorb light
energy to make food by photosynthesis.
• Sap filled vacuole is a space in the
cytoplasm filled with cell sap, which is
important for keeping the cells rigid to
support the plant.
MINI PLENARY Question 4
What is the function of the
chloroplast?
1.
2.
3.
4.
Controls the cell
Stores water and mineral ions
Makes glucose by photosynthesis
Controls what enters and leaves the cell
MINI PLENARY Question 5

1.
2.
3.
4.
Supports and protects the cell

Controls the cell
Controls what enters and leaves the
cell

CELLS
Palisade Cell
• Designed for
Photosynthesis
• Found in the top of a
leaf
• Tall and has a large
surface area to
absorb water and
minerals.
• Packed with
chloroplasts to help
make plant food.

Chloroplasts
Root Hair Cell
• Designed for
absorbing.
Vacuole
•Thin cell wall
makes it easy
for minerals to
pass through.
thin cell wall
•Has a large
surface which
helps it to
absorb water
and minerals.
Cell membrane
•Found in a
plant root.
