Notes

Limitation of comparative investigation is that when it is done on a huge population, huge amount cost is required. Example, whhen it is done on humans. cells have a nucleus and cell wall
autototrophs use sunlight to produce food use sexual and asexual reproduction
nonvascular plants mosses liverworts and hornworts are examples of nonvascular plants lack true roots stems and leaves have no specialized tissues rely on diffusion for nutrient transport have no seeds reproduce sexually and asexually
valscular plants have specialized tissues that aid in the transport of nutrients have true roots stems and leaves reproduce sexually and asexually
seddless vascular plats seedless vascular plants are among are oldest plants on earth do not produce seeds release spores
angiosperm flowering seed plants are called angiosperms produce flowers produce fruit that contain seeds
gymnosperm nonflowering seed plants are called gymnosperms do not produce flowers do not produce fruit have exposed seeds
A plant whose seeds are exposed rather than protected by fruit is called a(n) gymnosperm.
A plant that has flowers and whose seeds are protected by fruit is called a(n) angiosperm.
Geraniums are annual plants that many people use when organizing flower boxes. Choose the best answer to describe this geranium plant. The geranium is a vascular plant and has a short life cycle.
animals are multicelluar organisms organisms that have cells that contain a necleus heterotrophs that consume other oganisms organisms that reproduce using sexual and asexual reproduction
and invertebrate is an animal ithout a backbone does not have an internal skeleton has a hard outer covering called an exoskeletonScientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Scientific inquiry includes the traditional science processes, but also refers to the combining of these processes with scientific knowledge,critical thinking and scientific reasoning to develop scientific knowledge.
