- Plasmogamy involves the fusion of cytoplasm between two parent fungi without nuclear fusion, forming a secondary mycelium with one nucleus from each parent. Karyogamy involves nuclear fusion and produces genetic variation through somatic diploids.
- Animal cells lack cell walls and have structural proteins like collagen to hold their multicellular bodies together. Most animals reproduce sexually through fertilization and have a diploid stage dominating their life cycle.
- Animal development proceeds through cleavage, formation of a blastula and gastrula, and then organogenesis from the three germ layers. Their multicellular origin can be traced to colonial protistan ancestors.
The document discusses key concepts in cell biology including:
- Cells are the basic unit of structure and function for all living things
- Organelles allow cells to carry out specialized functions through compartmentalization
- The cell theory established that all organisms are composed of cells, cells come from preexisting cells, and cells carry out essential life processes
- Important early scientists like Schleiden, Schwann, and Virchow contributed to the development of the cell theory through their microscopic studies of plant and animal cells.
The document discusses the process of digestion in animals. It begins by explaining that digestion breaks down important substances like proteins, carbohydrates, fats, and nucleic acids that the body needs. It then covers the differences between plant and animal nutrition, and discusses how digestion provides evidence of evolution. Various aspects of digestion systems are explained, including intracellular and extracellular digestion. The stages of digestion - ingestion, digestion, absorption, and elimination - are outlined. Key organs involved in digestion like the mouth, esophagus, stomach, small intestine, large intestine are described along with their functions. Hormones that regulate digestion are also mentioned.
Prokaryotes are classified into two domains: Bacteria and Archaea. Bacteria are identified by their shape, cell wall composition, motility, and how they obtain and use energy. They reproduce asexually through binary fission. Genes can also be transferred between bacteria through conjugation, increasing genetic diversity. Prokaryotes play crucial roles in ecosystems through nutrient cycling and symbiotic relationships, but some can also harm humans.
A disease is defined as any change that interferes with normal body functioning. The Germ Theory of Disease states that infectious diseases are caused by specific infectious agents like viruses, bacteria, fungi, or parasites. Koch's postulates provide a method to determine if a specific pathogen causes a particular disease by finding the microorganism in diseased subjects but not healthy ones, being able to isolate and grow it in culture, and using the cultured version to reproduce the disease in a healthy subject. Diseases can spread through direct or indirect contact, fecal-oral transmission, airborne droplets, or vectors. The body defends against disease through non-specific and specific immune responses.
Primitive vascular plants evolved adaptations for life on land including vascular tissue for transport and alternation of generations. They include psilophytes which were the earliest vascular plants with no specialized organs, lycophytes with true roots, stems and scale-like leaves requiring water for reproduction, and sphenophytes with whorled leaves and siliceous stems requiring water for motile sperm. Advanced ferns have well-developed vascular tissue and xylem and phloem, thriving in damp habitats with a dominant sporophyte and inconspicuous gametophyte reproducing via spores in sori on fronds.

This document defines key terms related to excretion and osmoregulation in organisms. It discusses the processes of filtration, reabsorption and secretion in the kidney and the roles of specific kidney structures like nephrons and the loop of Henle in urine formation. It also covers osmoregulatory structures in different animals, hormones involved in urine regulation, and adaptive processes like hibernation, estivation and torpor.
This document contains questions for a student about osmoregulation - the process by which aquatic organisms regulate their internal salt concentrations. It asks about nitrogenous waste products in different organisms, and the effects of freshwater vs saltwater on fish. It also asks questions about thermoregulation in humans and how water is used to cool engines and nuclear reactors. The conclusion section is blank.
The mammalian kidney filters blood in the glomerulus and regulates water and salt balance through selective reabsorption and secretion in the nephron's tubule segments. In the proximal tubule, most reabsorption occurs, while the thin ascending loop of Henle secretes salt and the thick ascending loop reabsorbs salt actively. The collecting duct determines salt excretion, reabsorbing water passively. Osmoreceptors detect blood osmolarity and volume changes, triggering antidiuretic hormone and the renin-angiotensin-aldosterone system respectively to regulate water and salt balance. Through selective tubule transport, the kidney maintains homeostasis.
The document contains a worksheet asking students to identify different methods of heat transfer and label parts of the skin. It asks students to provide everyday examples of conduction, convection, radiation, and changes of state. It also has a diagram of the skin and asks students to match descriptions to the correct layers labeled A-O.
The immune system defends the body against pathogens through layered lines of defense. The innate immune system provides immediate nonspecific responses while the adaptive immune system mounts targeted responses through lymphocytes. B and T lymphocytes recognize pathogens through antigen receptors and mount humoral or cell-mediated responses involving antibody production or cytotoxic killing. Immune memory develops from these responses to provide faster protection upon reexposure. A balanced immune response is needed, as deficiencies or issues with self-tolerance can lead to infection or autoimmunity.

1) First line is external non-specific defenses like skin and mucus.
2) Second line is internal non-specific defenses like white blood cells and antimicrobial proteins.
3) Third line is internal specific defenses using B cells, T cells, and antibodies for a targeted response.
