Competencies

Science, Grade 5: Differences in Plant Groups Recognize the different groups of plants

Describe characteristics of different kinds of plants Classify plants into flowering plants, cone-bearing plants, ferns

and mosses Identify economically important and endangered kinds Suggest activities they can do at their level to help conserve

plants

Objectives

At the end of the topic, students should be able to: describe characteristics of different kinds of plants; describe the characteristics of plant groups; describe the similarities and differences between plant groups; identify causes of plant endangerment; suggest ways to conserve plants.

Essential Concepts

Plants are classified into moss, fern, cone-bearing and floweringplants.

Moss Plants are the tiny, low-lying plants which thrive on damp andshady areas. They have no true leaves and roots. Instead, they havetiny, root-like structure called rhizoids which anchor them on soil,rocks, decayed woods and fractures of floors. They are flowerless anddon't produce seeds. They reproduce through spores.The spores aredust-like structure produced in spore capsules held in thin stalks thatgrow from the moss plant.

Fern Plants are the leafy, non flowering plants which grow in moist/wet areas under the shade of forest. They vary in sizes. Some grow ashigh as 24 meters, others are just very small. They have true roots,leaves and stems which allow the flow of water and nutrients to all itsparts. They reproduce by spores. These spores are held in tiny sacscalled sporangia. The sporangia clump together into what are calledsori and appear like small clumps of spots or patches on the undersideof the fertile frond (leaves).

Cone-bearing Plants are the plants which produce seeds arranged in acone. They are also called Gymnosperms because their seeds are not

enclosed by a fruit. Gymnosperms means naked seed. They are woodyand nonflowering. Their leaves are green and look like needles/scaleswhich are adapted to dry environment. Some lives on very cold placeswhile others on warm places. They have true roots, leaves and stems.This group of plant includes pine tree, pitogo, fir, spruce.

Flowering Plants are the plants which bear flowers where some areshowy/or noticeable, some are microscopic and some do not look likeflower at all. They produce seeds which are enclosed in a fruit. Thus,they are also called Angiosperms. They have true roots, leaves andstems. Among the plant groups, it is the most diverse and widespread.They live on every habitat except on extreme environment likedeepest part of the ocean, highest mountaintops and polar regions.Itincludes the grasses, fruit trees, squash, roses, orchids, etc.

Philippines is one of the world's "biodiversity hotspots". Only few areleft on native plants found in the Philippines, some are facing highdegree of threat. Some of the economically important and endangeredplants are Almaciga, Rattan, Waling-waling, Philippine Date Palm andTree Fern.

The leading cause of plant endangerment is habitat loss/alteration dueto logging, mining and conversion of land to industrial, agricultural andrural development. Others include unregulated collection/cutting/overexploitation, pesticides/pollution, competition with other speciesand disease.

Department of Environment and Natural Resources (DENR) is thegovernment agency responsible for the inventory and conservation ofplants.

Organizational Strategies

Set your classroom for group activities Secure permit from school head for adopt/plant a tree activity Coordinate with the head of the community/incharge for adopt/plant

a tree activity look for places within the school that is appropriate for gardening

(vegetable, flower,medicinal plant, garlic and onion) Set safety/precautionary measures in handling breakable and pointed/

sharp objects.

Specific Vocabulary

Angiosperm is a group of plant which produce seeds enclosed in afruit. Examples are squash, beans, durian, grasses, etc.

Boreal forest is a forest consisting mainly of coniferous trees like pinetrees, spruce, fir, etc.



Classify means to organize things into groups according to theircommon characteristics.

Coniferous tree is any tree which bear seeds arranged in cone. Conservation is a careful preservation and protection of something; a

planned management of natural resource to prevent exploitation,destruction or neglect.

Conserve is to avoid wasteful or destructive use of natural resources. Economically important plants are plants which have actual or

potential value in trade or utilization for commercial purposes. Endangered species means a population of an organism which is at

risk of becoming extinct because it is either few in numbers orthreatened by environmental or predation parameters.

Endemic means unique or exclusively native to a certain place. Habitat is a place where one naturally lives and grows. Leaf sheath is the lower part of the leaf which surrounds the stem

more or less completely. Nonvascular plants are the plants which lack channels that carry the

water and nutrients to its parts. Spores are dust-like reproductive elements of plants. Vascular plants are plants whic possess well developed system of

conducting tissues to transport water and nutrients to their parts. Whip is a long, slender structure. Rattan's leaf sheath and leaves have

whips which aids it in creeping.
