2. HABITAT
• place where a certain kind of plant lives.
• Three main types of plant habitats:
1. Terrestrial
2. Aerial
3. Aquatic
3. TERRESTRIAL HABITAT
• a land habitat.
or – plants that live on land, ranging
from small plants to tall tree.
• Plants living here have stiff stems that gold them upright and allow them to
get sunlight. They also have rigid roots which allow the plants to grow tall
and get more sunlight. The roots also enable the plant to grow deeper into
the soil to get more water and nutrients. Narra and mango tree have even
thicker roots to get more nutrients for these big plants.
4. • DESERTS – a terrestrial habitat that is hot, and arid. Plants living here have
adapted to the very hot and dry conditions of the deserts, have very few leaves or
leave at all to prevent water loss, store all the water in their enlarged thick stems. Ex:
cacti
5. • Shaded areas like forests– plants have larger leaves (not as much sunlight
that will dry out the water from them).
• Other terrestrial plants – have tendrils that allow them to cling to or climb up a
support to go in the direction of sunlight. It includes vine like cadena de amor.
6. AERIAL HABITAT
• Plants live on the branches and trunks of trees or any other support to
which they attach. The roots are found above the ground, they absorb
moisture and some nutrients from the air.
• Plant collects their food, most nutrients, and water from the air or from the
materials that fall on them.
• These plants are called or , sometimes called
.
• Ex: orchids, different variety of ferns, cattleya, and vanda orchids.
7.
8. AQUATIC HABITAT
• water habitat.
• Plants living here are called or .
• The plants leaves do not have cuticle (protective film that covers the outer
layer of the leaf that prevent water loss from plants).
• The plants leaves near the surface have an increased number of stomata
(most of the time are open and the guard cells on the stomata is inactive
because of the abundance of water in the vicinity of the aquatic plants).
• The plants stem are less rigid or hollow than the stems of terrestrial and
aerial plants.
9. AERIAL HABITAT
• Large flat leaves help them to float on the surface of water.
• Smaller roots of aquatic plants allow water to diffuse directly into the leaves.
Some have feathery roots that have no need to support the plants.
• Others have specialized roots designed to take in oxygen, like the one in
mangrove trees.
• Water lilies’ roots grow deep into the water.
