the organisms. Unicellular organisms are those organisms that are microscopic and comprise of only one cell‚ whereas a multicellular organism consist of many cells. Prokaryotes‚ protists and several fungi are unicellular. They absorb nutrients directly through their body surfaces and excrete them by use of pseudopodia. Gaseous exchange is through their body surfaces. Multicellular organisms on the other hand have their cells organized into complex tissues and organs and body processes like respiration

I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

Prokaryotic Cell- single celled: only DNA+ structure (“before nucleus”) E.g. zygote-complete DNA Eukaryotic Cell-multi-celled (“after nucleus”) Prokaryotes Eukaryotes DNA In “nucleoid” region Within membrane-bound nucleus Chromosomes Single‚ circular Multiple‚ linear Organelles None Membrane-bound organelles Size Usually smaller Usually larger- 50 times Organization Usually single-celled Often multicellular Sexual Reproduction None Meiosis: Combination of DMA from 2 cells 3 postulates of cell

Introduction: In this essay I will talk about two kinds of organisms that are called worms. That’s organisms use it in a labs. Which are the flatworm and the roundworms. However‚ every kind belongs to different phylum‚ so they are not closely related to each other. Flatworms ( phylum Platyhelminthes) and roundworms ( phylum Nematoda)‚ but there are many similarities and differences between these two types of organisms. Similarity: • There are many similarities between the two groups of worms‚ Platyhelminthes

CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described
