Botany Task 1

In roots, which structure increases surface area for the absorption of water and minerals from the soil? 

• Root hairs

• Root cap

• Casparian strip

• Vascular cylinder

You are planning to build a swimming pool in your backyard.  How close can you get to the trees in your backyard without disturbing their root structure? 

• all the way up to the trunk

• within a foot of the trunk

• up to the crown of the tree

• at least 4-5 times the diameter of the crown of the tree

Most of the water obtained by a plant enters through the 

• cambium layer.

• palisade cells.

• root hairs.

• stomata.

Which of the following is not a major function of roots? 

• absorb water

• produce hormones

• anchor and support the plant

• transport of materials throughout the plant

The point on a stem to which a leaf or bud is attached is termed the 

• bud scale.

• axillary bud.

• node.

• internode.

Which of these associations is incorrect?

• ground tissue-parenchymal cell

• ground tissue-tracheid

• vascular tissue-sieve-tube member

• vascular tissue-vessel element

Which cells are relatively unspecialized and correspond to a generalized plant cell? 

• epidermal

• tracheid

• parenchyma

• sclerenchyma

If you wanted to grow a new plant in the laboratory with the appropriate technology, which tissue type would you not start with? 

• companion cells

•  parenchyma cells

•  sieve-tube members

• epidermis

You need to identify a plant but it is winter and the leaves have fallen to the ground mixed with others. The parts of flowers, fruits, and seed leaves of germinating seeds are not available either. Your best clue to whether it is a monocot or a eudicot is to 

• inspect the stem for woody bark since only eudicots have woody tissue

• determine if there is an apical meristem at the tip of the plant which indicates it is a monocot

• cut the stem and if the vascular bundles are in a distinct ring, it is a monocot

• cut the stem and if the vascular bundles are scattered in the stem, it is a monocot

The specialized tissue in a root that functions in food storage is the

• epidermis

• endodermis

• cortex

• pericycle
