Biology Unit 23

Match the following

•  ground tissue for photosynthesis

• meristem

• dermal tissue in leaves and young plants

• ENDODERMIS

• actively dividing unspecialized cells

• MESOPHYLL

• encloses the vascular cylinder

• collenchyma

• Thick-walled cells in ground tissue

• epidermis

Match the following

• mesophyll cells that absorb light

• sclerenchyma

• small openings in the epidermis

• stomata

• thin-walled cells in ground tissue

• palisade mesophyll

• make seed coats tough and strong

• parenchyma

• the thin, flattened part of a leaf

• blade

Match the following

• xylem and phloem tissues in a leaf

• petiole

• stalk that attaches a leaf to a stem

• adhesion

• loose tissue with air between cells

• lead vein

• in cells of tracheid make wood tough

• spongy mesophyll

The plant organ that supports the body and carries nutrients between different parts of the plant is the

• root

• stem

• leaf

• flower

Tracheids and vessel elements make up

• phloem

• trichomes

• xylem

• meristem

Phloem functions primarily in

• transport of water

• growth of the root

• transport of products of photosynthesis

• increasing stem width

Which of the following are found in roots?

• vascular tissue only

• ground tissue only

• dermal and vascular tissue only

• dermal, vascular, and ground tissue

As a growing root pushes through the soil, the delicate apical meristem is protected by

• a root cap

• xylem

• bark

• root hairs

Which of the following is a trace element absorbed by roots?

• nitrogen

• zinc

• phosphorus

• potassium

The waterproof strip that is found in the cell walls of the endodermis is the

• vascular cambium

• vascular cylinder

• Casparian strip

• cortex
