4. • The leaves of a terrestrial plant have tiny
openings underneath them called
stomata, which allow air to pass through.
• The roots supply the plants with water
and nutrients from the soil or from the air.
• Stems hold terrestrial plants upright so
that they can absorb plenty of sunlight.
5. Woody Plants
- They have hard and usually brown stems.
- They can be small plants
- They can be big plants
- They are used for making fences or
furniture, or for building houses.
- They provide good shade from the sun
during the hot, summer months.

7. Specialized structures:
• The inner part of their stems and branches is
wet.
• The outer part is hard and woody.
These characteristics prevent the plants from
drying out when exposed to air.
Woody plants can be classified as trees, vines,
and shrubs.
8. Trees – are woody plants that grow big.
Their stems, called trunks, are very hard and
usually wide.
Examples: Acacia tree, Narra tree,
Malunggay tree, kakawate tree, etc.

10. Shrubs – are small, woody plants. Their
stems are upright and they do not grow very
tall.
Examples: sampaguita, orange, kalamansi,
etc.
12. Vines – are plants climb or crawl on trellises.
- some vines have twiners, that twist
around other plants or anything that they
touch

are organs that grow out of their stem and
curl around a nearby object.
Examples: squash, grapes, morning glory,

15. Non-woody Plants
- They have soft, smooth, and usually green
stems.

plants.
Example: kangkong, pechay, kamote,
kinchay, and saluyot
- Cactus and aloe vera, have waxy
structures.
- Banana plant, though big inn size, is also
classified as nonwoody.

18. Aquatic Plants
- are also called hydrophytes
Three types of Aquatic Plants:
1. Submerged
2. Floating Water Plants
3. Emergent Plants
19. Submerged Aquatic Plants
- These are rooted plants that live
underwater.
- They have soft stems
- They receive little amount of sunlight as
water becomes deeper
Example: Hydrilla

21. Floating Water Plants
- Their body keeps most above the water.
- Their roots are not attached to the soil
- Their leaves are broad and firm or leathery
but flexible
- The upper part has many stomata for gas
exchange.
Example: Water hyacinth
22.
23. Emergent Plants
- They are rooted on watered-down soil
- Their leaves and body have are above
water
- Their stem are stiff or firm
- They are often found along shorelines
Example: Wild rice, taro or gabi plants
