3. ROOTS
• parts of the plant that are buried
in the soil from which they absorb
water and minerals. Also hold
plant firmly to the ground.
• Two types:
- Taproot – large main root with
smaller roots branching out. Ex:
sugar beet, carrot, and radish.
- Fibrous – network of slender
roots, hence its fiber like
appearance and no main root. Ex:
rice, corn, grass, and onion
4.
5. STEM
• part that transports water and
minerals from the roots to the
other parts of the plant. Also
holds the leaves, flowers, and
fruits of the plants.
• Two types:
- Woody stems – hard and stiff. Ex:
various kinds of trees
- Herbaceous stems – soft and
flexible. Ex: kogon grass, aloe vera,
kangkong, kamote, and garlic
6. LEAF
• part where the plant makes its food
in a process called photosynthesis.
• Made of parts:
- Apex – tip
- Petiole – stalk connects the leaf to
the stem
- Blade – flat structure on each side of
the middle main vein
- Midrib – middle main vein
- Stomata – small openings
- Guard cells – open and closes the
stomata, allowing the exchange of
the gases like CO2 and oxygen.
7. • Leaves differ on size, shape, and color. They can be small or big. They can
vary from round to oval to heart-shaped.
• Most leaves are green due to chlorophyll, a pigment that is found in
plant cells called chloroplast.
8. • Venation – arrangement of veins.
– Veins – structures that serve as passageway of water and nutrients needed
by leaves. They also provide support to the leaves.
9. FLOWER
• main reproductive part of a plant. It produces seeds from which young
plants grow and develop.
• Parts:
- Stamen – male reproductive part of a flower.
- Filament – thin stalk that holds the anther, which bears the pollen grains.
- Pistil – female reproductive part
- Stigma – sticky part that traps the pollen grains
- Ovary – contains the ovule, later becomes fruit, ovule becomes the seed
- Style – stalk connects the stigma to the ovary
- Sepals – small, green, leaflike structures that cover, and protect the bud and
hold the petals together.
- Petals – colorful parts that attract insects.

11. FRUIT
• part that contains the seeds.
• seeds – part that grows
develops into a new plant.
• Fruits of plants differ in shape,
size, color, and texture.
13. TREE
• A plant that is big and tall and
generally lives for many years.
• It has a main woody stem called
trunk.
• Its roots are long and big.
• Most trees bear flowers and
produce fruits.
• Ex: mango tree, coconut, and
narra tree.
14. SHRUBS
• Looks like small tree
• Has several woody stems and
hard fibrous roots
• Most shrubs are flowering plants
• They only live for few years than
trees
• Ex: santan, gumamela, rose, and
rosal
15. HERBS
• Plant with soft juicy stems and
doft fibrous roots.
• Also bears flowers
• Different part of this plant are
used as food and material for
medicine
• Live for shorter time than shrubs
and trees
• Ex: mayana, katakataka, oregano,
garlic, and pechay
16. VINES
• Plant that has weak stem and
roots that cannot support the
whole plant, so it climbs or
creeps on the ground or on walls
• Some also attach themselves to
some support, such as sticks,
trellises, or other plants
• Have shorter life spans than
other kinds
• Ex: ampalaya, squash, patola, and
upo
