|
Name the structures and functions. |
Top: A megastrobilus is a female cone that produces a megaspore (femalespore) inside of an ovule. The megaspore develops into a female gametophyte, which produces an egg . . . all of these steps taking place inside of a single ovule. Bottom: A microstrobilus is a male cone that produces microspores (male spores), inside microsporangia which develop into male gametophytes (pollen) |

|
|
Pine pollen (left), magnified with 40x lens. Pollen = male gametophyte (produces sperm cells). |
|
|
Pine pollen growing pollen tube, through which sperm would travel to get into ovule where egg waits. |
|
|
SEED is synapomorphy for Spermatophyta. Adaptive significance: protects the Sporophyte embryo during dispersal |
|
What is the name of the circular structure of the vascular tissue in most angiosperms as seen from a stem cross section? |
Eustele |
|
|
|
|
How many years old is the stem?
|
3 years. |
|
|
|
|
Identify the function of: Axilliary bud |
Dormant meristem tissue that becomes active when the apical meristem is damaged. |
|
Identify the function of: Leaf primordia |
Immature leaves that develop into adult leaves. |
|
What does ovule contain BEFORE pollen tube reaches it? |
An egg cell, polar nuclei, and antipodal cells. |
|
What develops in ovule AFTER fertilization? |
Seeds. |
|
What does ovary develop into? |
A fruit. |
|
What is the function of anther? |
It is the pollen producing structure on the stamen (male) |
|
What is the function of stigma? |
It is the tissue that is the receptor of pollen grains. |
|
What is the function of petals? |
To attract pollinators. |
|
What is the function of sepals? |
Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. |
|
|
|

|
|
|
Describe the type of leaf veination and its associated classification. |
parallel, characteristic of monocots. |
|
Describe the type of leaf veination and its associated classification. |
Netted or Reticulate, characteristic of dicots. |
|
What is the difference in vascular tissue between Monocots and all other angiosperms? |
Monocots have no order in of vascular tissue in as seen from a stem cross section where all other angiosperms' vascular tissue forms a circular structure. |
|
What is the function of the root cap? |
To protect the roots apical meristem. |
|
What is the function of the cortex? |
Starch or energy storage. |
|
What is the function of the vascular cambium? |
Secondary growth. |
|
|
|

|
What is the adaptive significance/function of the Xylem? |
Xylem transports water and solutes from the roots to the leaves |
|
What is the adaptive significance/function of the Phloem? |
Phloem transports food/glucose from the leaves to the rest of the plant. |
|
|
|
|
What is the adaptive significance/function of the mesophyll? |
It is the part of the leaf that contains chloroplasts and photosynthesis takes place. |
