Summative Topic Check

The strongest plant cells are...

• Parenchyma cells

• collenchyma cells.

• sclerenchyma cells.

• dermal cells.

What is the function of collenchyma 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

The function of the vascular tissue is to...

• secrete a substance that becomes the cuticle.

• cover the outside of a plant and protect it.

• provide support and supply materials.

• transport water and nutrients to all parts of the plant.

Cohesion is a result of hydrogen bonds that form between...

• water molecules.

• water and the xylem wall.

• water and the phloem wall.

• none of these options

Which type of tissue makes up most of the inside of a plant?

• Dermal

• Ground

• Vascular

• Phloem

How do you think parenchyma cells are 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 allow growth despite their thick walls.

Trees do not have a structure that pumps 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 unable to transport water and dissolved mineral nutrients.

• The vascular system would be unable to transport the products of photosynthesis.

• The vascular system would be made up mostly of photosynthesizing cells.

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 through the phloem.

• They would be unable to form sclerenchyma cells.

Which of the following is common between the monocot and the dicot plants?

• They have the same number of flower petals.

• Their seeds have the same number of cotyledons.

• Their vascular system is made up of Xylem and phloem.

• They have the same root structure.
