Briefly explain how gaseous exchange takes place in terrestrial plants.
Answers
Answer:
Gaseous exchange, or respiration, is the process in which terrestrial plants take in oxygen from the air and release carbon dioxide. It involves a series of biochemical processes that take place within specialized cells embedded within the plant's leaves.
The first step of gaseous exchange in terrestrial plants is diffusion, where molecules move from an area of high concentration to an area of lower concentration. In this case, atmospheric oxygen diffuses into leaf cells through small openings on their surface called stomata. As these molecules enter the leaf cells, they are taken up by specialized photosynthetic organelles known as chloroplasts.
Chloroplasts then absorb energy from sunlight and use it to combine CO2 with water (H2O) to produce sugars and other organic compounds such as amino acids and lipids (photosynthesis). The resulting reaction produces chemical energy stored in the form of ATP (Adenosine Triphosphate). This ATP drives various metabolic pathways that use oxygen as well as glucose for cellular respiration. During this process, some oxygen enters the cell while some carbon dioxide is released back out into the atmosphere through small openings on their surface called stoma – completing the cycle of gas exchange between terrestrial plants and their environment.
Explanation:
In terrestrial plants, gaseous exchange takes place through tiny openings called stomata on the surface of leaves. These stomata allow for the exchange of gases such as carbon dioxide and oxygen with the surrounding atmosphere. During photosynthesis, carbon dioxide enters the plant through the stomata, while oxygen produced during photosynthesis exits through the same openings. This process enables plants to obtain the necessary carbon dioxide for photosynthesis and release oxygen as a byproduct.

The discoverers of DNA were not James D Watson and Francis Crick. They are the first scientist to formulate an accurate description of the DNA’s (deoxyribonucleic acid) complex , double-helical structure. They discovered that base pairing nucleotides must be; adenine and thymine; and cytosine and guanine. These base pairs are held together by a hydrogen bond, atype of chemical reaction that s easy to break and easy to reform. The statement is “DNA is a double helix made of two strands linked together with hydrogen bonds.”

To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the possibilities of each event are multiplied.
If a ratio is 5 guanine to 1 adenine, this means that the possibility of adenine to be created is
Now, we will use the multiplication rule to calculate the possibility of creation each of these 5 copolymers:
GGG -
GAA -
AAA -
GAG -
AGA -
According to this, the greatest possibility to be created has copolymer GGG.

The given question says a cross is performed between two homozygous recessive individual, both having genotype ttyy.
In any case, the gametes produced by these plants would be recessive for the trait and the cross between these individual would always give rise to a homozygous recessive progeny.
Hence, in any case, the progeny would be homozygous for allele t, and allele y.
So, the probability of offspring having homozygous for gene t and homozygous for gene y would be 100% or 1.

Transport
Explanation:
Living organisms are characterized by essential day-to-day activities which they undergo to sustain their life. One of these life processes is called TRANSPORT, which involves the circulation and absorption of nutrients.
Transportation is a life process where substances synthesized or absorbed in one part of the body are carried to other parts of the body. This life process is important in plant and animals as it leads to movement of nutrient, water, mineral, gases etc. In humans, circulatory system is responsible for this process of transportation.
