This document discusses the reproductive parts of plants. It defines flowering and non-flowering plants, with flowering plants bearing flowers that develop into fruits or seeds, while non-flowering plants produce seeds but no flowers. The parts of a flower are then described, including the pistil and stamen, which are the female and male reproductive parts, as well as other structures like the receptacle, sepals, and petals. Different types of flowers like perfect, imperfect, complete and incomplete are also defined.

1. SCIENCE 5
Reproductive Parts in
Plants
Objectives:
• Identify the parts of a flower;
• Describe the reproductive parts in plants and their functions; and,
• Differentiate flowering from nonflowering plants.

2. CLASSIFICATION OF
PLANTS

3. Flowering Plants
• They bear flowers that
eventually develop into fruits
or seeds.
• Most flowers are both male
and female.
• They attract pollinators with
their color and fragrance.

4. Non Flowering Plants
• They produce seeds but do
not bear flowers.
Examples are:
Conifers, Cycads, Gingkos

5. PARTS OF THE
FLOWER

6. Parts of the Flower

7. Pistil
It is a female reproductive part.
It has four parts namely:
• Stigma – Catches pollen grains
• Style – Long tube that attaches the
stigma to ovary
• Ovaries – Storage place of egg cell
• Ovules – The egg cell of plants

8. Stamen
•It is composed of
anther and filament.
Anther – It is responsible
of producing pollen.
Filament – It is the
structure that supports
the anther.

9. Other Structures For Support Of The
Flowers
•Receptacle – It is the part
of branch where flower
forms.
•Sepals – Leaf-like structures
that enclose the flower
before it blooms.
•Petals – Colorful structure
that make the flower
attractive to pollinators.

10. •Pollen – Produced in
the anther of a
specific flower is
meant to fertilize
another flower of
the same kind.

11. TYPES OF FLOWERS

12. Perfect Flowers
• Flowers that have both the male and female reproductive
structures.

13. Imperfect Flowers
• Flowers which have only male reproductive structures or only female
reproductive structures are called imperfect flowers.

14. Complete Flowers
•It has the stamen, pistil, petals, and sepals.

15. Incomplete Flowers
•They lack one of these parts.
