HIGH SCHOOL TOPIC THAT DISCUSSES SEED IN PLANTS AND ITS TYPES.IT ALSO INCLUDES ACTIVITIES THE TEACHER CAN ENGAGE THE STUDENTS WITH THROUGH OUT THE LEARNING PROCESS. INTERACTIVE VIDEOS ARE ALSO INCLUDED AND SOME TAKE AWAY QUESTIONS AT THE END OF THE PRESENTATION. THE PRESENTATION ALSO DISCUSSES THE PARTS OF A SEED AND THEIR FUNCTIONS FOR C;LARITY TO THE LEARNERS.

1. Seeds and Fruits

2. PERFOMANCE OBJECTIVES:
2
at the end of this class, students should be able
to;
1) Identify seed and fruit
2) Define seed and fruit
3) Differentiate between endospermic and non-
endospermic seeds.
4) State the difference between monocot and
dicot
5) Discuss seeds and the different parts of a
seed and their functions.

3. • CLASSIFY THE SPECIMENS INTO;
A. FRUITS:
B. SEEDS:

WARM UP

4. Seeds
• A seed is a mature ovule that
comprises an embryo or a miniature
undeveloped plant and food
reserves, all enclosed within a
protective seed coat. Seeds are a
way of reproduction for all flowering
plants.

6. FRUITS
• A fruit is a mature, ripened ovary, along
with the contents of the ovary. The
ovary is the ovule-bearing
reproductive structure in the plant
flower. The ovary serves to enclose
and protect the ovules, from the
youngest stages of flower
development until the ovules become
fertilized and turn into seeds

8. WHAT IS THE FUNCTION
OF;
 SEEDS
 FRUITS

9. Seeds and Fruit
• Fruits are formed by
seed plants to aid in
dispersing seeds
• A seed contains the
developing plant embryo
in a protective coat
(testa)
• Seeds form from ovules
fertilized in the ovary
• Ovaries with seeds ripen
into dry or fleshy fruits
9

10. Parts of a Seed
• External seed coat or testa
• Developing plant embryo
• Stored food called endosperm
• Seeds may be in one part (monocot) or
two parts (dicots)

13. DICOTYLEDONOUS AND MONOCOTYLEDONOUS
SEEDS
 Depending on the number of cotyledons present,
the seeds are of two types: dicotyledonous and
monocotyledonous seeds.
 Dicotyledonous: Seeds have two cotyledons.
Dicot seeds are far more in number than
monocot seeds, e.g. beans, groundnut, sunflower
etc..
 Monocotyledonous: Seeds have one cotyledon,
e.g rice, maize, wheat etc.

15. Dicot vs. monocot seed
Dicot has two cotyledons
(like bean)
Endosperm (food) is kept
in the _________
Monocot has one
__________ which
absorbs the endosperm
tissue during
germination (corn)

(5) DIFFERENCES BETWEEN A
MONOCOTYLEDON AND A
DICOTYLEDON SEED?
2. Differentiate between the following:
(i) Endospermic and Non-endospermic
Seeds
(ii) Hypocotyl and Epicotyl
(iii) Epigeal and Hypogeal Germination
