Chapter 35 Quiz

If a plant did not produce axillary buds, it would likely not be able to form

branches or some flowers

Carbon dioxide entering a leaf moves through the air spaces and ultimately into the vascular tissue where it reacts with the products of photosynthesis and is stored within sugar molecules.

false

In comparing primary and secondary growth,

secondary growth results from activity of the lateral meristems, while primary growth results from activity of the apical meristems.

Label the regions of the root in the diagram.

1. Zone of Maturation 2. Zone of elongation 3. Zone of cell division 4. Root cap

Which of the following does not correctly describe an anatomical feature of a leaf?

Epidermis - waxy and transparent, it covers of the entire surface of the leaf. The upper surface contains many stomata.

The apical meristem produces bark in eudicots.

False

Match the root function with the type of modified root in which it is present

Prop roots-produced in the lower part of the stem in monocots to brace the stem aerial roots- produced by epiphytic plants to attach to their host plants. Pneumatophores-aid in oxygen uptake for plants growing in aquatic or waterlogged habitats Contractile roots- act to pull roots deeper into the ground Parasitic roots-Penetrate vascular tissue of a host plant Food storage roots- Contain many parenchyma cells filled with carbohydrates Water storage roots- contain water for plants in arid regions Buttress roots- provide support for large tropical trees

Which of the following does not correctly pair a modified stem with its function and features? Bulbs and corms - perennial, underground stem that remains dormant during unfavorable conditions Cladophylls - photosynthesis in desert species Runners and stolons - horizontal underground stem that functions for vegetative growthCorrect Tuber - underground stem for storage Tendrils - attachments and climbing

Runners and stolons - horizontal underground stem that functions for vegetative growth

All of the following are functions or features of root hairs except

roots hairs are also known as lateral roots

In lab, you are given a plant sample and asked to determine the type of plant tissue. After looking in the microscope, you have a hypothesis and to test it you apply iodine to the sample. Areas of the sample turn a very blue-black. Based on this analysis, you determine that

the sample contains starch and starch is stored in ground tissue.
