Kingdom Plantae 1

Unit Goals (as they relate to plants) Students will analyze the nature of the relationships between structures and functions in living cells. a. Explain the role of cell organelles for both prokaryotic and eukaryotic cells, including the cell membrane, in maintaining homeostasis and cell reproduction. d. Explain the impact of water on life processes (i.e., osmosis, diffusion). Students will analyze how biological traits are passed on to successive generations. e. Compare the advantages of sexual reproduction and asexual reproduction in different situations. Students will derive the relationship between single-celled and multi-celled organisms and the increasing complexity of systems. a. Explain the cycling of energy through the processes of photosynthesis and respiration. b. Compare how structures and function vary between the six kingdoms (archaebacteria, eubacteria, protists, fungi, plants, and animals). 2

Unit Goals (as they relate to plants) Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystems. e. Relate plant adaptations, including tropisms, to the ability to survive stressful environmental conditions. Students will evaluate the role of natural selection in the development of the theory of evolution. d. Relate natural selection to changes in organisms. 3

Kingdom Plantae Characteristics b. Compare how structures and function vary between the six kingdoms (archaebacteria, eubacteria, protists, fungi, plants, and animals). Kingdom Plantae Characteristics are multicellular. are eukaryotes. are autotrophic. photosynthesize. have cellulose cell walls. can reproduce sexually & asexually have tissues that have been organized into organs and organ systems. Plants Organisms are grouped into kingdoms based on genetic and anatomic similarities. 4

Brief History of Plants d. Relate natural selection to changes in organisms. Brief History of Plants Green algae are believed to be the ancestors of modern plants The invasion of land by plants probably occurred about 450 million years ago First land plants were small mosses and ferns that had to live near water. Plants slowly began to adapt to life on land, and spread to all biomes and climates. -----Adapting to different environment. We are going to look at adaptation that plant have to help them survive in different environments. 5

What plants need & how they obtain it. Overview Plants are called autotrophs, meaning “self-feeding.” They make Glucose (a carbohydrate) from sunlight energy. Need: Energy Carbon Dioxide Water Other minerals 7
