Characteristics of Gymnosperms

Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. They have a vascular system (used for the transportation of water and nutrients) that includes roots, xylem, and phloem. The name gymnosperm means “naked seed,” which is the major distinguishing factor between gymnosperms and angiosperms, the two distinct subgroups of seed plants. This term comes from the fact that the ovules and seeds of gymnosperms develop on the scales of cones rather than in enclosed chambers called ovaries.

Gymnosperms are older than angiosperms on the evolutionary scale. They are found far earlier in the fossil record than angiosperms. As will be discussed in subsequent sections, the various environmental adaptations gymnosperms have represent a step on the path to the most successful (diversity-wise) clade (monophyletic branch).

Gymnosperm Reproduction and Seeds

Gymnosperms are sporophytes (a plant with two copies of its genetic material, capable of producing spores ). Their sporangia (receptacle in which sexual spores are formed) are found on sporophylls, plated scale-like structures that together make up cones. The female gametophyte develops from the haploid (meaning one set of genetic material) spores that are contained within the sporangia. Like all seed plants, gymnosperms are heterosporous: both sexes of gametophytes develop from different types of spores produced by separate cones. One type of cone is the small pollen cone, which produces microspores that subsequently develop into pollen grains. The other type of cones, the larger “ovulate” cones, make megaspores that develop into female gametophytes called ovules. Incredibly, this whole sexual process can take three years: from the production of the two sexes of gametophytes, to bringing the gametophytes together in the process of pollination, and finally to forming mature seeds from fertilized ovules. After this process is completed, the individual sporophylls separate (the cone breaks apart) and float in the wind to a habitable place. This is concluded with germination and the formation of a seedling. Conifers have sperm that do not have flagella, but instead are conveyed to the egg via a pollen tube. It is important to note that the seeds of gymnosperms are not enclosed in their final state upon the cone.

Answer:

Gymnosperms produce both male and female cones, each making the gametes needed for fertilization; this makes them heterosporous.

Megaspores made in cones develop into the female gametophytes inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores.

Conifer sperm do not have flagella but rather move by way of a pollen tube once in contact with the ovule.

The portions of eukaryotic mRNA sequences that are removed during RNA processing are introns.

An intron is a region of a gene that does not stay in the final, mature mRNA molecule after that gene is translated and does not encode the amino acids that make up the protein for which that gene is responsible. The majority of the human genome's protein-coding genes are composed of exons and introns.

The most important function of introns is alternative splicing, which enables many proteins to be produced from a single gene. Some introns go through further processing after being spliced so they can encode functional RNA molecules.

Answer:

Ionic compounds are ion compounds. These ions are atoms that gain or lose electrons, resulting in a net positive or negative charge. Metals tend to lose electrons, so they have a net positive charge and become cations. Non-metals tend to gain electrons, creating a net negative charge of anions.

Explanation:

Cardiac output is influenced by several factors, including heart rate, stroke volume, and systemic vascular resistance. These factors work together to determine the overall cardiac output.

Cardiac output is the volume of blood pumped by the heart per minute and is influenced by heart rate, stroke volume, and systemic vascular resistance.

Heart rate (HR) is the number of times the heart beats per minute. An increase in heart rate leads to an increase in cardiac output, as more beats result in more blood being pumped.

Stroke volume (SV) is the volume of blood ejected from the heart with each contraction. It is influenced by factors such as preload, contractility, and afterload. An increase in stroke volume leads to an increase in cardiac output.

Systemic vascular resistance (SVR) refers to the resistance that blood encounters as it flows through the systemic circulation. An increase in systemic vascular resistance decreases cardiac output, as more resistance impedes blood flow.

Heart rate, stroke volume, and systemic vascular resistance interact to determine cardiac output. For example, an increase in heart rate can compensate for a decrease in stroke volume or an increase in systemic vascular resistance to maintain cardiac output.

Explanation:

Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed.

Yeah your answer is correct

Answer:

Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.

The major difference between an endospore of a bacterium and an exospore of a fungus is that B, endospores are dormant forms which are highly resistant to environmental stresses, while exospores are not.

Endospores are formed by some bacteria, such as Bacillus anthracis, as a means of survival in harsh environments. They are metabolically inactive and can withstand extreme temperatures, radiation, and chemicals. When conditions improve, the endospore can germinate and the bacterium can resume its normal life cycle.

Exospores are formed by some fungi, such as actinomycetes. They are not as resistant to environmental stresses as endospores, but they can help the fungus to disperse and colonize new areas.
