Plant cells
Plant cells contain a nucleus, a
strong cell wall, which gives the cell
its shape, a cell membrane and
cytoplasm. They contain
chloroplasts, which give plants their
green colour and are used in
photosynthesis. Finally, plant cells
have a large vacuole. This contrains
water and minerals.

 Ferns reproduce using spores.
 Angiosperms have flowers and seeds.
 Algae dont have roots, stems, leaves and
flowers.
 Gymnosperms make seeds in cones.
 Mosses have very simple roots, stems
and leaves.
 The mystery word is: SOIL
p. 29 ex 6 Identify the key words
All plants share some important characteristics.
Firtly, plants are producers, which means they can
make their own food. Secondly, all plants interact
with their environment. They can react to light,
temperature and water. Thirdly, almost all plants
are green because their cells contain chlrophyll.
Finally, all plants reproduce. Some plants
reproduce by growing flowers which then produce
seeds. This is called sexual reproduction. Other
plants use asexual reproduction.

p. 7 ex 1 Write descriptions of
the plants in the photos.
 A) This is an angiosperm. It has roots, a stem,
leaves and flowers. It produces seeds and fruit too.
 B) This is a fern. It has roots, a stem and leaves. It
doesn’t have flowers. It doesn’t produce seeds or
fruit.
 C) This is a moss. It has very simple roots, a stem
and thin leaves. It doesn’t have flowers. It doesn’t
produce seeds or fruit.
 D) This is a gymnosperm. It has roots, a stem,
leaves and flowers. It doesn’t produce any fruit.
The seeds develop in cones.
 E) This is an algae. It doesn’t have true roots,
stems, leaves or flowers. It doesn’t produce seeds
or fruits.
P. 7 ex 2 – Read the definitions
and write the words.
 Cone : this is where the gymnosperm’s seeds
develop.
 Fronds: These are large, long leave on a fern. They
are divided into many narrow sections.
 Flowering plants : These types of plants produce
flowers.
P. 7 ex 3 – Odd one out.

1. Because it is a plant part.
2. Because it is not a type of plant
p. 8 ex 4 The characteristics of
the plants
a. How do plants get their nutrients?
Plants get their food by photosynthesis
b. What do plants react to?
Plants react to sunlight.
c. How do most plants reproduce?
Most plants reproduce by seeds

the cell.
b. The cell wall protects the cell and gives it its shape.
c. The nucleus controls the functions of the cell.
d. The vacuole contains water and minerals.
e. The cytoplasm is where chemical reactions happen.
f. The chloroplasts help during photosynthesis.
p. 8 ex 6 The parts of the plant
 Leaves are the parts of the plant where it makes its
food. They contain the chlorophyll whih is
necessary for photosynthesis. On the underside of
the leaf there are tiny pores which are called
stomata. Carbon dioxide is taken in and oxygen
passes out through each of these pores.
 The stem supports the plant. Water and minerals
travel through the stem to the leaves for
photosynthesis. The stem then distributes the food
to the other parts of the plant.
 The roots hold the plant in the ground. If you look
closely at a root, you can see tiny hairs, which are
called root hairs. Roots absorb water and minerals
needed for nutrition from the ground.

 Stem because it’s not part of a leaf.
 Stem because it supports the plant.
p. 9 ex 8 Photosynthesis
 Plant cells called xylem cells, carry sap, a mixture
of water and minerals from the soil.. This sap
travels through the stem to the leaves. Colour this
sap green.
 The chlorophyll in the chloroplasts in the plant cells
traps energy from the sun. Colour the sunlight
yellow.
 The leaves absorb carbon dioxide from the air
through their stomata. Colour this gas red.
 The chlorophyll traps energy from the Sun to make
glucose. Plant cells carry the glucose in phloem sap
to the rest of the plant. Colour this sap orange.
 The plant expels excess oxygen through the
stomata. Colour this gas blue.
p. 9 ex 9 Photosynthesis
a. What do the roots take in during
photosynthesis?
The roots take in water and minerals during
photosynthesis.
b. What do the leaves take in during
photosynthesis?
The leaves absorb (=take in) carbon dioxide
c. What helps the plant trap energy from the Sun?
The chlorophyll in the chloroplasts in the plant
cells traps energy from the Sun.
d. What sap is produced by plant cells in the
leaves?
The phloem sap is produced by plant cells.

Sexual reproduction
 Most flowering plants use sexual reproduction.
The flowers have both male and female organs.
The male organs are called stamens. Each one
has a long filament and an anther at the end.
This is where the plant produces pollen. The
female organ is in the centre of the flower and is
called the pistil. It catches the pollen with a
sticky part called the stigma. From here the
pollen travels down a long tube called the style
and into the ovary. When the pollen and an ovule
join together, they make a seed.

to reproduce.
