Plants have characteristics that make them different from other eukaryotic organisms. One of the main differences is that they are autotrophic, meaning they are able to make their own food using simple inorganic substances. They do this through a process known as photosynthesis, in which plants convert sunlight, water, and carbon dioxide into sugar and oxygen. Photosynthesis occurs in the chloroplasts of a plant cell. Plants are multicellular and, unlike animals, their cells have rigid cell walls made from cellulose. Some species of plants reproduce sexually and some reproduce asexually. In asexual reproduction, such as budding, an exact copy of the parent is produced. Plant sexual reproduction can be assisted by animals, as is the case with flowers and honeybees. As the bees go from flower to flower collecting nectar, they carry pollen, plant sex cells, with them and pollinate other plants. Pollination is the first step in plant sexual reproduction. The Kingdom Plantae is divided into 11 Phyla. For example, Phylum Bryophyta are mosses- small, soft plants that don’t have flowers. They absorb water and nutrients through their leaves, which are 1 cell thick. Kingdom Plantae Cell Type? (Prokaryote or Eukaryote) Eukaryotic Unicellular or Multicelluar? Multicellular Autotroph or Heterotroph? Autotroph Cell Wall? Yes, cellulose Example Pine tree, moss Animalia Domain Eukaryota Kingdom Animals are a group of multicellular eukaryotic organisms. The word animal comes from the Latin word animalis meaning “having breath.” Animals are different from other eukaryotes in a number of ways. First, animal cells lack the rigid cell wall that plants, fungi, and algae have. Instead, animal cells are surrounded only by a cell membrane. Second, animals are heterotrophic, meaning that they must ingest other organisms in order to survive. Heterotrophs are the consumers in the food chain. Third, all animals are motile, or able to move, at least during one stage of their life cycle. Nearly all animals undergo some form of sexual reproduction, where specialized sex cells form and fuse together to form zygotes, which develop into individuals. Some animals are also capable of asexual reproduction, through budding or forms of cloning. The Kingdom Animalia is divided into approximately 40 Phyla including Phylum Chordata, which includes all the vertebrate animals, or animals with a backbone and spinal column. Humans, as well as fish, birds, reptiles, amphibians, and other mammals, belong to the Phylum Chordata. Other phyla include Phylum Arthropoda, to which crabs, spiders, and insects belong; and Phylum Nematoda, which are the roundworms. maturing fish eggs zygotes human cheek cells human muscle tissue Kingdom Plantae Animalia Cell Type?

Describe 2 conclusions that can be made from this information. The information below describes the most specific levels of classification that the mushroom sea squirt, Sycozoa gaimardi, shares with four other organisms. •The mushroom sea squirt is in the same class as the common sea grape. •The mushroom sea squirt is in the same family as the blue spot ascidian. •The mushroom sea squirt is in the same order as the white speck tunicate. •The mushroom sea squirt is in the same phylum as the starry skate. 12. To which of the four organisms is the mushroom sea squirt most closely related? Blue spot 13. Which of the beetles above must belong to the same family? Hippodamia… Student 14. Four students researched the classifications of the following eight whales: killer whale, Orcinus orca gray whale, Eschrichtius robustus humpback whale, Megaptera novaeangliae pygmy right whale, Caperea marginata fin whale, Balaenoptera physalus minke whale, Balaenoptera acutorostrata North Atlantic right whale, Eubalaena glacialis bowhead whale, Balaena mysticetus The students were asked which two whales are most closely related and why. The table below summarizes the students’ answers. Based on the classifications, which student gave the correct answer to the question?
