Now that the pollen grain is mature, what has happened to the micro sporangia?
The microsporangium is likely to wither and then stop producing the microspores.
#85 what is the term given to this stage of the anther
Dehiscent
#91
Why is the endosperm being digested?
#92
How are the seeds of this three similar and how are they different
#93 what does the staining pattern tell you about the content of the endosperm and embryo
Fruit
#94 what type of fruit does each item represent
- Drupe
- Berry
- Pepo
- Pome
- Complex fruits
- Dry fruits
#95 does this structure look to have arisen from a single carpel housing multiple seeds or multiple carpels each housing one seed
Multiple carpels each housing one seed.
#96 is the sunflower a monocot or dicot
They are dicots. This is because they have the characteristics which qualify them to be dicots. For instance their embryo with two cotyledons which usually develop above the ground. They also posses the vascular tissues; xylem responsible for the transportation of water and tissues which is responsible for the transportation of dissolved food materials in the plant.
#97 if a corn grain is actually a fruit, where is the pericarp.
In the kernel of the maize. It is the pericarp of the fruit which is fused with the seed coat which is also referred to as the caryopsis.
#98 does a corn grain have a cotyledon as well as the endosperm
Yes it has both the cotyledon and the endosperm. The cotyledons develop t become the first embryonic seedlings of the seed while the. On the other hand, the endosperm acts as the nutritive tissue for the for the embryonic seeds. In a nut shell, the endosperm provides nourishment to the developing embryo inside the seed. It ensures that enough food is available which can sustain the organism.
#99 How many carpels are fused to form an apple
It is prudent to note that the Apples contain five compartments which are called carpels. These compartments fuse together as the Apple grows. It is also important to note that different Apples have different numbers of seeds in each of the carpels. However, this depends on the health of the fruit together with that of the tree.
#100 how might the fleshy pericarp aid in seed dispersal
It is prudent to note that the fleshy pericarp can play a great role in seed dispersal especially in the wetlands; the fleshy pericarp is always light and can float on water or the flood zones hence facilitating seed dispersal.
#101 how many carpels are fused to form a tomato
It is prudent to acknowledge the fact that Tomatoes too have carpels. However, it is not easy to arrive at the exact answer about how many carpels fuse together to form a carpel. What we can say is simply that, the number of carpels which fuse together to form a tomato is not very easy to calculate.
#102 what structures do you think the jelly-like material is.
The jelly-like structure is the placentas which give rise to the ovules which later grow o become a seed.
Question 79
What are the pink-stained string like-structures seen within the cells
It is the placenta.
Ecosystem worksheet diversity
It is important to note that the species diversity index is an expression of community structure and is a characteristic unique to the community level of the organization, Shanon indices is one of the most widely used species diversity indices that is used for examining the overall community characteristics.
What are some of the reasons why these areas have different diversity values?
It is important to note that different in species may be attributed to different reasons. For instance, a community may express or demonstrate high species diversity if many or equally abundant species represent. On the other hand, if a community is composed of only very few species, then the species diversity i9s likely to be low.
We can also say that a community or a region with high species diversity may be as a result of the presence of factors which support such species. Therefore, communities with higher species diversity typically imply that they have higher levels of energy transfer. This means that availability of food can also determine the degree of species diversity. The levels of predation, competition and the availability of niche all determine the differences in species diversity.
Species richness refers to the number of species which has been recorded for a specific group of
organisms during a specific period of time there is great difference in species richness between Gary and Hoosier. For instance, the species richness in Hosier is greater compared to Gary. The difference in species richness can be attributed to the difference in ecosystem. For instance, a Hoosier which is a national forest is likely to have more different species compared to an urban area. This is the reason for the differences in species richness between Gary and the Hoosier. Therefore, the richness values correspond with my expectations.
Greater evenness value is better for the survival of species. This is because such evenness reduces stiff competition which might be present in the ecosystem for the limited available resources. Reduced competition increases the chances for survival.
