What is the function of the sporangium? question 11 options: a) passes characteristics from one generation to the next b) forms haploid cells through mitosis c) protects the mature gametes d) protects the developing mother spore cells
Answers
Answer:
D) Protects the developing mother spore cells
Explanation:
A structure called a sporangium is found in some plants and other creatures and is responsible for producing and storing spores. Spores, which are haploid structures made by organisms, aid in the germination and formation of new organisms.
A structure called a sporangium is found in some plants and other creatures and is responsible for producing and storing spores. Spores, haploid structures produced by organisms, aid in germination and the development of new species. They assist in the process of reproduction, in other words. What does it actually imply that they are haploid, though? Simply said, it indicates that there are just half the chromosomes needed to create a complete diploid creature. The sporangia can divide through mitosis, or cell division, to manufacture and release spores.
A single, potentially complex morphologically produced sporangium is produced by an unbranched sporophyte in mosses, liverworts, and hornworts. The majority of ferns, many lycophytes, and non-vascular plants are homosporous (only one kind of spore is produced). Some ferns, the majority of lycophytes, and some bryophytes are heterosporous (two kinds of spores are produced). These plants generate gametophytes that are functionally male or female, respectively, by the development of microspores and megaspores. Occasionally, two types of spores are generated in the same sporangium and may even form a spore tetrad together.
Microsporangia and megasporangia, two different types of sporangia, are present in the majority of heterosporous plants. All seed plants, as well as a few ferns (Salviniaceae and Marsileaceae), some lycophytes (genera Selaginella and Isoetes, as well as the extinct lepidodendrids), are heterosporous with two types of sporangia.
Sporangia can grow near the terminals of stems, along their sides, or in close proximity to leaves. In ferns, sporangia are often located on the abaxial surface of the leaf, or the underside, where they are tightly grouped into clusters called sori. An indusium, a type of structure, could be present across Sori. The sporangia of certain ferns are dispersed along with the shortened leaf segments or along (or just in from) the leaf edge.
The sporangium has an indirect involvement in sexual reproduction and an active part in asexual reproduction in several phyla of fungus. The sporangium, which has haploid nuclei and cytoplasm, develops on the sporangiophore. Each haploid nucleus and cytoplasm are encased in a hard outer membrane as the spores develop in the sporangiophore. These spores spread by wind during asexual reproduction and develop into haploid hyphae.
Although sexual reproduction in fungus differs between phyla, the sporangium indirectly contributes to sexual reproduction in some fungi. When two haploid hyphae from different individuals combine to produce a zygosporangium in response to adverse circumstances, sexual reproduction takes place in Zygomycota. The zygosporangium's haploid nuclei subsequently combine to form diploid nuclei.
When the environment is more favorable, the zygosporangium germinates, goes through meiosis, and develops into a sporangium that releases spores.

why are viruses not regarded as true living cells?
Answers
Explanation:
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.
What is environment?Environment is defined as a compilation of all the factors living and nonliving and the outcomes they have on human life. Due to their ties to the forest, its plants, wildlife, water, and air. The air is filtered and hazardous gases are absorbed by the forest and trees. Plants filter water, lessen the likelihood of flooding, preserve the natural equilibrium, and do many other things.
Viruses are more like robots than actual living things, even though they do replicate and adapt to their surroundings. The viruses are thought to be dead in their natural habitat since they lack any cell-like properties. However, inside the host cell, the viruses employ the host's technological infrastructure to carry out all necessary tasks including reproduction.
Thus, viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.

How do you think about the invention of the microscope? Influenced the cell theory?
And what are the components of the cell theory?
Answers
Answer:
See the answer below
Explanation:
The invention of the microscope paved way for the development of the cell theory because, without it, the cell and all the organelles of the cell would not have been discovered and or studied in great detail. It was through the use of a microscope that Robert Hooke was able to observe and name the cell and it was through the same microscope that the fine details of the cell were able to be studied by other scientists, culminating in the formulation of the cell theory.
The cell theory states that all living organisms are made up of cells, the cell is the basic unit of all life, and cells can only arise from already existing cells (via cell division). The components of the cell theory, therefore, are:
Living organisms are made up of cells.The cell represents the basic unit of life.Cells can only arise from preexsiting cells.Please help me out!

Explain the mechanism of ventilation in human lungs (you should talk about the diaphragm, abdominal muscles and rib cage and intercostal muscles)
Answers
Answer: When the diaphragm contracts, it moves inferiorly toward the abdominal cavity, creating a larger thoracic cavity and more space for the lungs. Contraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity.
The movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.
The ventilation in human lungs or pulmonary ventilation is defined as the process of intake of air during inhalation, and expiration as the release out of air. It is also termed as breathing.
What is the mechanism of pulmonary ventilation?The lungs are present in the thoracic cavity, with the diaphragm below the lungs separating the thoracic cavity from the abdominal cavity. The rib cage is present outside lungs and prevent them.
Inhalation process in pulmonary ventilationThe inhalation is the process of taking in air. The increase in the volume of lungs results in the increased movement of diaphragm to the abdominal cavity.
The intercostal muscles move upwards and the rib cage move outwards. Thus, the air is inhaled in the system.
Exhalation process in pulmonary ventilationThe exhalation of air is performed antagonist to the inhalation. The relaxation of diaphragm and the movement of rib cage results in the decreased volume of the lungs, and the air is expelled.
Thus, the movement of diaphragm and ribs govern the mechanism of ventilation in human lungs.
