Why do some plants die? PARTS OF THE PLANTS  Plants make our surroundings beautiful and attractive. They grow in almost all kinds of environment. There are many plants around us.  ROOTS The roots hold the plant to the ground. They absorb water and minerals from the soil and bring these up to the stem and leaves. Roots have three main parts: primary root, secondary roots, and root hairs.  ROOTS Primary root - the first and largest root to form in a plant. It usually grows straight down into the soil. Secondary roots - small roots that branch out from the primary root. Root hairs - these roots grow from secondary roots and are very fine roots that look like short pieces of strings. TYPES OF ROOT SYSTEM Taproot System: plants that have a large and well-developed primary root that grows deep into the soil. Examples are plants like carrots and radish. carrot roots  TYPES OF ROOT SYSTEM Fibrous Root System: plants that have a well-developed secondary root system. The primary root stops growing but many secondary roots grow from it. Examples are corn and rice. corn roots  STEM The stem is the one that supports the plant. It is where the leaves, flowers, and fruits are attached. It grows upward toward the sunlight. It also carries water from the roots up to the leaves and food from the leaves down to the roots.  KINDS OF STEM Woody Stems non-green stems that are thick and hard. They are covered with bark. Bark is the rough, outer covering of a woody stem.  Woody Stems mango tree gumamela shrub bataw TREES VINES Tall plants with one big SHRUB Shrubs are woody plants Some vines have hard stems. stem called trunk. They They creep and cling on any have hard, woody, and with short and hard stems branching near the ground. solid objects or other plants branching stems. for support.  KINDS OF STEM Herbaceous Stems plants with herbaceous stems have soft and green stems and usually do not grow as tall as plants with woody stems.  Herbaceous Stems HERBS HAVE HERBACEOUS STEMS lettuce cabbage pechay  LEAVES The leaves of plants are usually green in color because of chlorophyll or the green coloring pigment that captures light energy from the sun. This light is used as energy in photosynthesis.  LEAVES Photosynthesis is the process in which plants absorb light from the sun and convert it to chemical energy stored as food.  PARTS OF A LEAF Blade - the expanded portion of the leaf Midrib - the middle part of the leaf blade Petiole - the leaf stalk that connects the leaf to the stem  KINDS OF LEAVES SIMPLE LEAF has only one leaf blade attached to a petiole guava leaves  KINDS OF LEAVES COMPOUND LEAF consists of many leaf blades attached to one petiole malunggay leaves  SHAPES OF LEAVES banana leaves BROAD LEAVES wide and flat leaves  SHAPES OF LEAVES wheat leaves NARROW LEAVES long and slender leaves without a wide blade SHAPES OF LEAVES pine leaves NEEDLE LEAVES similar to sewing needles, thin, pointed, and range from 1-5 inches  FLOWERS There are plants that bear flowers called flowering plants and plants that do not bear flowers are called non flowering plants. Flowers differ in size, texture, color, and fragrance.  PARTS OF A FLOWER Petal - the colorful parts of a flower Sepal - smaller than petals and green in color Receptacle - holds the petals and sepals together  FRUIT A fruit is the matured or ripened ovary of a flower. The fruit is the part that contains the seeds. Fruits are either fleshy or dry. They also vary in size, shape, and color.  FLOWERING PLANTS These are plants that bears flowers or fruits NON-FLOWERING PLANTS These are plants that does not bear flowers or fruits FACT or BLUFF  FACT OR BLUFF Read the statements in the next slides and tell if it is a fact or a bluff. Flowering plants are plants that grow flowers or fruits.  The roots have three parts: primary, secondary, and tertiary roots.  The leaf stalk that connects the leaf to the stem is called midrib. Plants need water, sunlight, air, and nutrients from the soil to thrive. Shrubs and herbs are plants with woody stems.  When plants have a well-developed primary root it is called a taproot system. A compound leaf is when there are many leaf blades attached to one petiole.  Plants with non-green stems that are thick and hard are plants with herbaceous stems.  Do you think plants could have helped in these situations? How? PRAYER  Leader: Mother Seton, All: Pray for us. Leader: God has done great things for us, All: May God be forever praised. Alleluia!
