Provide support and supply materials
Transport water and nutrients to all parts of the plant
Cohesion is a result of the hydrogen bonds that form between
Water molecules
Water and the xylem wall
Tracheid cells
Vessel elements
The figure shows a cross section thru a tree. What does each ring represent?
One winter of growth
One year of growth
Five years of growth
Ten years of growth
The functions of plant stems include providing support, transporting water and minerals, and
Taking up water from soil
Forming a vascular cylinder
Storing food and water
Exchanging gases
Which leaf adaptations occur to minimize water loss in both deserts and cold dry climates?
Plump leaves that store water
Large and broad leaves
Needles and spines
Compound and double compound leaves
The upper surfaces of leaves are used mainly for...
Light gathering
Gas exchange
Collecting water
Protection from predators
Water loss is not a problem for what group of plants?
Desert plants
Aquatic plants
Cold-climate plants
Dry-climate plants
What is the function of the plasmodesmata?
They support and protect plants
They allow cells to share materials
They store starch, oils, and water
They carry out photosynthesis
Trees do not have a structure that pumps out fluids like a heart. How do fluids move from the roots to the leaves of trees without a pump?
The properties of water move fluids up trees.
Trees do not need to transport fluids.
Water is pushed when pressure is applied to the roots.
Hydrogen bonds are stronger in trees than in animals.
What would happen if a plant’s vascular system contained only xylem?
The vascular system would stIll function normally
The vascular system would be made of mostly photosynthesizing cells
The vascular system would be unable to transport water and dissolved mineral nutrients
The vascular system would be unable to transport the products of photosynthesis
Mineral nutrients are usually dissolved in water as...
Protein
Iron
Nitrogen
Ions
Primary growth increases a plant’s
Flowers
Branches
Length
Thickness
Which of these processes requires a plant to use energy?
Moving water into the phloem
Lifting water up the xylems
Losing water by transpiration
Loading sugars into the phloem
What happens to the guard cells when a plant is losing water from transpiration faster than it is gaining water at its roots?
They deflate and open the stomata
They inflate and open the stomata
They deflate and close the stomata
They inflate and close the stomata
What problem would most plants face if they tried to grow in an aquatic environment?
Forming flowers
Exchanging gases
Getting nitrogen
Staying warm
Which type of cell is found in the hard or gritty parts of fruits and vegetables?
Collenchyma
Sclerenchyma
Parenchyma
Plasmodesmata
Plant cells that have thin walls and store starch, oils, and water are...
Parenchyma cells
Collenchyma cells
Sclerenchyma cells
Vascular cells
Dead parenchyma cells that make up bark form a type of...
Collenchymal tissue
Vascular tissue
Dermal tissue
Ground tissue
A plant’s ground tissue is found...
in its outer layer
Only in its leaves
Above the ground
Throughout the plant
Water and dissolved minerals are carried from the roots to the rest of a plant by the...
Dermal tissue
Ground tissue
Xylem
Phloem
The strongest plant cells are...
Parenchyma cells
Collenchyma cells
Sclerenchyma cells
Dermal cells
What is the function of sclerenchyma cells?
To store starch, oils, and water for the plant
To provide support while allowing the plant to grow
To transport materials through long strands
To connect different types of cells
Transpiration lowers the pressure in the leaf xylem, creating a vacuum that...
Forces water out of the leaves
Pulls water upward
Attracts water to the xylem wall
Moves water into the phloem
Which type of tissues makes up most of the inside of the plant?
Dermal
Ground
Vascular
Phloem
How are parenchyma cells important in healing a plant’s wounds?
They can regenerate throughout the plant’s life
They have very tough cell walls
They are not needed for photosynthesis
They all growth despite their thick walls
What makes sclerenchyma cells tough and durable?
Their ability to change size
Their second wall hardened by lignin
Their cytoplasm and organelles
Their tendency to form long strands
Mineral nutrients are usually dissolved in water as...
Protein
Iron
Nitrogen
Ions
How would most plants first be affected if they did not lose water by transpiration?
They would be unable to carry out photosynthesis
They would be unable to lift water to their top branches
They would be unable to move sugars thru the phloem
They would be unable to form sclerenchyma cells
