Without plants, humans and animals alike would die. Yes, that sounds drastic, but really…I’m serious!

It is easy to look at plants on the surface and regard them as nothing more than another part of nature, which humans have already damaged quite a bit. Nature, as a whole, should be untouched and live freely, but plants in particular are vital to our well-being, and also provide us with many necessities in our lives.

Plants, like animals, can either produce sexually or asexually (or sometimes both). If a plant reproduces sexually, the offspring is genetically different from that of the parents. An asexual offspring is genetically identical except with mutation comes into play.

Erosion is the deterioration of soil and minerals on the ground. A riverbank that has no plant-life around it would sure gain composure and life if a native species were to planted. It is on the lateral edge of a river, and if a native species were planted, it would definitely help.

The circulatory system of plants and animals differs greatly. In animals, the main parts of the circulatory system include the heart and the vessels, and mammals have a closed circulatory system, and what circulates in this system is blood.

Detached earlobes are very common in humans. The detached earlobes are due to a dominant gene (D) and attached earlobes due to the recessive gene (d). A man with heterozygous detached earlobes marries a woman with attached earlobes. What percent of their F1 offspring will have attached earlobes?

Alleles
Detached- D
Attached- d

Phenotypic Cross
Detached earlobes  x Attached earlobes

Genotypic Cross
Dd x dd

Gametes
Dd x dd

Phenotypic Ratio
2 Detached : 2 Attached

Genotypic Ratio
0 DD : 2 Dd : 2 dd

Therefore, 50% of the F1 offspring will have detached earlobes.

Plants and animals may not appear to be very similar, but one of the things they have in common is that they both respire. To understand respiration, it is first important to understand photosynthesis and to be able to distinguish the two from one another.

Many people think a plant is just a plant. However, plants can be classified into two categories: angiosperms and gymnosperms. While the names appear to be very difficult to pronounce, differentiating between the two is actually more simple than one might imagine…once you learn a bit about the basics, of course.

We have already learned that plants can be classified into the two groups angiosperms and gymnosperms. It doesn’t stop there, blog-readers…Angiosperms can further be classified into Monocots and Dicots! The best examples used for these groups are bean seads and corn seeds. Corn seeds are monocots and bean seeds are dicots.
