2. Recognize the reproductive parts of flowering plants and their
functions
Describe the different modes of reproduction in flowering plants
- are multicellular organisms that can be distinguished
from other living things by a number of characteristics: They
make their own food. Plants are photosynthetic and contain a
green pigment called chlorophyll, which enables plants to
convert energy from the sun into food. Plants store their food as
starch.
It is used for producing plants easily.
It doesn’t involve sex cells in order to produce.
No seeds needed.
Parts of the plants are used for reproducing offspring.
3. In new plants are produced
from different vegetative parts such as .
is the reproductive part of a plant. A flower may be
with either the male or the female reproductive parts. A
flower has both the male and the female reproductive
parts.
1. Bulb - is any plant that stores its
complete life cycle in an underground
storage structure. The primary function
of these underground storage structures
is to store nutrient reserves to ensure
the plants' survival.
Examples of true bulbs: onion, garlic,
allium, daffodil, tulip, amaryllis, grape
hyacinth, Dutch hyacinth, Dutch iris,
scilla, lily.

6. Tubers
Tuber – is a swollen underground
stem or root of a plant from which
new plants can grow, as in the
potato.
The tubers then serve as a nutrient
store that allows the plant to
survive the cold and
later regrow and reproduce. Each
tuber has from two to as many as
10 buds (or “eyes”), arranged in a
spiral pattern around its surface.
The buds generate shoots that
grow into new plants when
conditions are again favorable.
Examples are potato, yam cassava
and dahlia.
7. Sexual Reproductive System of Flowering Plants
Male and female reproductive system of a plant is found in its
flower. Parts that provides
support and
protection to the
flower:
1. Sepal – protects
the bud until it
opens and
blooms
2. Receptacle –
base that holds
the whole flower
and also
connected to
pedicel
3. Pedicel - Flower’s
stalk
8. Main reproductive organ of
flower:
1. Pistil – female
reproductive part
- inside it is the ovary
where the ovule that
contains the eggs can be
found.
2. Stamen – male
reproductive organ
- Has anther where
powdery substances
(pollen grains encases
the sperm cells) located.
- filament is a long and
slender stalk that support
the anther in place.
