N5 Biology - Unit 2.5

Which of the following is not an important use of water in plants?

• For cell division

• Photosynthesis

• To keep cool

• To keep turgor

How does water enter plants?

• Enters the root hairs by osmosis

• Is taken in by the stomata

• Is absorbed from the air

• Diffusion

In order to absorb water, root hairs increase...

What are Xylem vessels?

• Tissues in plants that transport sugars

• Tiny pores on the leaf epidermis that allow gas exchange

• outer layers of cells of a root

• Dead, hollow tubes with lignin that transport water and minerals

What are these?

What is phloem used for?

• The transport sugars up and down the plant

• Cell division within plants

• Maintenance of the plant's structure

• To allow gas exchance

Which living cell within the phloem provides energy?

Which of the following plant vessels are living?

• Xylem

• Phloem

Which of the following describes the cuticle?

• A layer which consists of irregularly shaped cells which don't fit together

• A waxy protective layer that helps prevent water loss

• A skin where the stomata and guard cells are found

• A wall made up of cylinder shaped cells where most photosynthesis takes place

Which of the following describes the upper and lower epidermis?

• A skin where the stomata and guard cells are found

• A wall made up of cylinder shaped cells where most photosynthesis takes place

• A layer which consists of irregularly shaped cells which don't fit together

• A waxy protective layer that helps prevent water loss
