Through its parts - roots, stems, leaves, and flowers.
Flowers and fruits allow plants to ______.
reproduce
The leaves capture the _______,
energy of sunlight.
It enters the leaves and gives off oxygen?
Carbon dioxide
The ____ sends food and water to all parts of the plant.
stem
The ____ absorb water and nutrients from the soil.
roots
The ____ provides warmth and energy to plants.
sun
What will happen to the plants when there is too much sun?
The plant will wither.
What will happen to the plants when there is too little sun?
It will slow down the growth of the plant and may even kill it.
True or False: Plants contain chloroplasts.
True
Chloroplasts contain ______ a pigment that makes plant green.
chlorophyll
A process that takes place in the chloroplasts found in the cells of the plant. Most chloroplasts are located in the leaves of plants.
Photosynthesis
The ______ traps the energy from sunlight and converts it into chemical energy with the help of carbon dioxide and water.
chlorophyll
The photosynthesis process will produce ______ and ______.
sugar
oxygen
Leaves have very small openings called ________.
stomata
It allows gases to pass in and out of the leaf.
stomata
True or False: Carbon dioxide from the air enters the plant stomata.
True
Why is water important for plant growth?
It helps plants move nutrients from the roots up to the stems and leaves. Water keeps the plant moist and flexible.
It provides a base on which the roots hold on to. It also provides plants with water and nutrients.
Soil
Is it true that plant needs a suitable habitat?
True
Plants grown on land are called?
terrestrial plants
True or False: Many plants that grow in dry habitats store water in their stems?
True
Does cactus plant lives in a dry habitat?
Yes
Does Cactus has widespread root system to absorb as much water as it can?
Yes.
A plant that has small, fleshy, thick leaves that drop off during extreme dry climate. Their leaves have sharp points to protect them from predators that eat them.
Agave plant.
They have small leaves, protective thorns, tiny branches, and widespread root system to help them adapt to dry habitats.
Desert shrubs
Plants that usually have large root systems that grow as deep as 30 meters in search of water. Other plants have shallow, wide-spreading roots that absorb water during heavy desert thunderstorms.
Desert plants
True or False: Some desert plants bloom only after heavy rains. The plants die during dry seasons, but their seeds remain on the ground. When rain comes, the seeds sprout and grow.
True
True or False: In tropical countries like the Philippines, coconut palm trees grow in sandy soil with regular rainfall and lots of sunlight.
True
_____ have needlelike leaves that are coated with a thick , waxy cuticle that prevents water loss.
Pine trees
True or False: The shape of the Pine trees’ needles is narrow, which reduces its surface area and helps save water
True
True or False: Pine trees grow large roots that collect water deep underground.
True
True or False: Pine trees can produce food whenever conditions are right.
True
True or False: Mosses live together in large groups or colonies covering soil or rocks with a mat of tiny green plants.
True
True or False: Each moss plants has tiny, threadlike rootlets that absorb moisture and minerals from the soil.
True
Is it true that trees grow very tall in a rain forest?
True
True or False: Rain forest is warm and wet?
True
Rain forests receive a lot of _____ since it rains almost every day.
water
Plants in a rain forest have _____ leaves and grow in ______ like the evergreen.
broad
layers
Trees in rain forests are ______ and ______ that sunlight is almost blocked off.
tall
dense
The _____ or _____ forms a highway for animals that live in the rain forest.
tree top
canopy
_____ have fibrous root system that absorbs water over a large area.
Grasses
Is it true that the grass’ roots allow the grass to survive in dry conditions?
True
True or False: Grasses often grow on wide, flat plains?
True
Examples of grassland plants.
Buffalo grass
wild oats
clover
True or False: The shallow roots of the grass take in water before it dries up.
True
___ plants have special structures that enable them to live in marine or freshwater environments.
Aquatic
True or False: There is limited supply of oxygen in aquatic systems.
True
True or False: The stems of aquatic plants are much thinner and more flexible than those on land because of the surrounding water currents.
True
Is it true that the leaves of aquatic plants have little or no cuticle on them because they are not in danger of drying out?
True
The leaves of aquatic plants have ______ on the leaf surface where exchange of gasses occurs.
chloroplasts
Aquatic plants store the food they make either in the ____, _____, or at _____ where growth occurs.
roots
leaves
stem points
Aquatic plants produce most flowers _____ the surface of the water so that the flowers can easily attract _____.
above
insects
True or False: Aquatic plants have roots that help them stay in place.
True
This allows the aquatic plants to draw nutrients from the water.
roots
True or False: Aquatic plants may be floating, submerged or emergent.
True
A type of plants that have leaves that float on top of the water.
Floating plants
True or False: In floating plants, chlorophyll is restricted to the upper surface.
True
Examples of floating plants.
Lotus
Duckweed
Water Lily
How do water lilies adapt to live in water?
Floating plants like the water lily are not attached to the bottom. Most have roots from the floating leaves or lily pads that hang in the water.
A type of water lily that has very large, green leaves that lie on top of the water surface. Its leaf may grow about 3 meters in diameter.
Victoria
True or False: Some aquatic plants are submerged in the water.
True
You find these plants under the sea or inside the aquarium. They have soft stems that makes them rise above the surface of water.
Submerged plants.
True or False: Submerged plants lack strong water transport system in it stems. Instead, leaves directly absorb water, nutrients, and dissolved gasses.
True
Is it true that submerged plants has no stomata on their leaves?
True
True or False: Aquatic plants, such as Elodea, need enough space and anchorage?
True
True or False: Some aquatic animals will grow better if they are attached to rocks to secure them in place.
True
Examples of emergent plants.
arrowhead
cattail
______ plants are rooted plants, often along the shoreline that stand above the surface of the water.
Emergent
True or False: The stems of emergent plants are somewhat stiff or firm. Their leaves are very thin and narrow.
True
True or False: Emergent plants cannot grow in the deeper parts of the water since their stems and roots are not strong enough to support them against the water currents.
True
