Sem 2 Unit 1 Bio

Identify two strategies that plants utilize to facilitate the dispersal of their seeds

Animals eat seeds and disperse them with their poopie Wind dispersal

Snow Trillium, classify its floral symmetry and indicate whether is it a monocot or dicot

Bilateral Symmetry, Monocot

Identify the parts of the leaf's anatomy in the picture

Blade, Petiote

The sum of all the sepals is called the ____.

Calyx

Give an example of a food storage plant

Carrot

What makes the endodermis of a root semipermeable

Casparian strips with layers of subrin

The support cells that assist the sieve tube members with their day to day function are called the ___.

Companion cells

A grass would have two cotyledons

False

A rhizome is an example of a fibrous root system

False

Cells in the zone of elongation are actively dividing to form new cells

False

Mosses have small flowers for sexual reproduction

False

Sieve tuber members are part of the xylem tissue of a plant and are dead at maturity

False

The separation layer becomes embedded with suberin in the separation layer at the base of the petiole prior to leaf abscission

False

he antipodals of an embryo sac secrete chemical signals to direct growth of the pollen tube

False

self-incompatibility prevents pollination

False

Classify the type of leaf

Pinnately Compound

Identify two means of asexual selection used by plants

Potatoes produce tubers and those tubers can all grow to become new potatoes Roots like rhizomes can grow parallel to the ground under the surface and produce new plants along the way

Contrast primary growth with secondary growth and indicate where each would occur in a plant stem

Primary growth is vertical growth and occurs in the optical meristem Secondary growth increases the girth of the plant and occurs in the lateral meristem

Identify two functions of the root cap

Protects the root itself (specifically in cell division) and helps in the detection of gravity

The male parts of the flower above are collectively called the ___.

Stamens

Sclerenchyma fibers are often interpreted within the xylem tissue. Why?

They provide support for the xylem

Define transpiration and explain its importance for movement of material throughout the plant body

Transpiration is evaporation that occurs on the blade of a plant, the negative pressure caused by transpiration pulls up other resources, like water, through the xylem

A dioecious plant must have perfect flowers

True

A plant that germinates, flowers and then dies at the end of a growing season would be classified as an annual

True

A plant that is suffering from water loss would have its stomata closed

True

A plant with two leaves at each node on the stem would be classified as having an opposite leaf arrangement

True

Mycorrhizae increases the effective surface area of roots and increases the rate of absorption of water and minerals

True

The megaspore mother cell is located in the ovary of the female flower

True

Contarst the function of xylem with that of phloem

Xylem transports water and minerals, completely liquid Phloem transports food and nutrients, some solid material

What is the function of a guard cell in the leaf?

opens and closes stomata
