biology

• Title of the lesson is? plant and animal organ system and their function
• Saprotrophic organisms take food from another organism.
• Ectoparasitism is when the parasite is outside of the host.
• Heterotrophic organisms obtain nutrients from dead or decaying organic matter, examples include fungi and bacteria.
• Gas exchange involves the use of oxygen produced by photosynthetic organisms and the release of carbon dioxide to the environment as a waste product of respiration.
• Endoparasitism is when the parasite is inside of the host.
• Holozoic organisms obtain nutrients by digesting organic matter, examples include humans and termites.
• Parasitic organisms ingest solid or liquid food, then it will be digested and absorbed, examples include herbivores, carnivores, and omnivores.
• Gas exchange occurs at the leaves of plants, where gases enter the leaves through specialized pores called stomata.
• Animal groups use different structures for gaseous exchange, examples include lungs, air sacs, and tracheae.
• Organisms that are capable of manufacturing their own food from inorganic substances are referred to as autotrophic.
• At the unicellular stages, plants have positionally fixed cells and highly regulated body plans, while animals have motile cells and determined body plans.
• Nutrition is the process of providing or obtaining food necessary for health, survival, and growth of an organism.
• Asexual Reproduction does not involve gametes/sex cells and can be observed in some plants and lower forms of animals.
• Reproductive traits in Organisms include using physical characteristics to attract pollinators and sexual selection, where some male species compete with other males to copulate with females.
• Sexual Reproduction involves the union of gametes/sex cells inside or outside the body of the organism and is exhibited only by higher forms of organisms.
• Organisms that use chemicals for their survival as they live in a very harsh environment are chemoautotrophic.
• Reproduction is the biological process by which new individual organisms, "offspring", are produced from their "parent" or parents.
• Systematics is based on evolutionary relationships.
• Organisms that directly use the energy from the sun and other inorganic substances like CO2 and H2O are photoautotrophic.
• Biodiversity and Systematics are topics discussed at the end of the lesson.
• Development is the series of changes which animal and plant organisms undergo in their passage from the embryonic state to maturity, from a lower to a higher state of organization.
• Chemical control in animals involves hormones that are important for growth and survival.
• The ability of plants to respond to a certain stimulus is known as tropism.
• Plants, on the other hand, do not have a structural immune system and circulatory system.
• The sensory and motor mechanisms of animals are directly controlled by their nervous systems.
• The roots contain vascular tissues and its strands are supported by numerous cells forming the vascular cylinder.
• Plants react to light, chemicals, gravity, water, and even touch.
• The immune system is a complex network of organs, cells, and proteins that defends the body against infection, whilst protecting the body's own cells.
• The role of the immune system is to protect the organism from diseases or other potentially damaging foreign bodies.
• Vascular strands serve as the nerves in plants.
• The immune system identifies threats and finds ways to fight them.
• The leaves contain strands that combine to form the vascular bundles of the stem and the vascular cylinder of the roots.
• The immune system for animals is composed of complex interactions that allow the organisms to distinguish their own cells from foreign cells, as well as remember specific features of foreign bodies.
• Chemical control in plants also involve hormones needed for certain physiological processes in the body.
• Animals have nerves that carry information from the brain and spinal cord to the muscles and glands.
• Plants are equipped with receptors, and each plant cell contains receptors that recognize pathogen molecules.
• Plants have a serial nervous system, with the root tip or apex serving as a unit of its nervous system and numerous apices in the plant body connecting to the vascular strands, which are classified as plant nerves.
• The kidneys of freshwater vertebrates allow large amounts of ions such as sodium and chloride to go out of their bloodstream.
• These interconnections form the serial nervous system in plants.
