Protists Protists Are a Varied and Ancient Group of Organisms Protists are the most diverse of all organisms - most are unicellular - microscopic - few are complex and multicellular Characteristics - eukaryotes - some photosynthesis - some ingest their food - some absorb their food - some have flagella or cilia o used for locomotion or getting food - found almost everywhere there is water - damp soil

Animal cells vs. Plant cells Five Similarities Animal and plant cells have many of the same characteristic. Animal cells and plant cells are both eukaryotes. They both have cell nucleus which contain chromosomes or DNA‚ as well as cell membrane encompassing the cell to control the substances moving in and out of the cell. They both contain enzymes from liposome for breaking down larger molecules. Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum

Biology 110-12 . 1. What are the five kingdoms and give a brief description of each kingdom? Answer: Monera- Single celled prokaryotes;bacteria Protista - Mostly single celled eukaryotes; Photoautotrophs (algae) and heterotrophs (protozoa) Fungi-Multicellular eukaryotes that feed by extracellular digestion and absorption Heterotrophs: includes decomposers‚ many pathogens and parasites Plantae-Multicellular photosynthetic autotrophs producers Animalia- Diverse multicellular heterotrophs Range from

com/difference/Animal_Cell_vs_Plant_Cell C. Form a hypothesis 1. Hypothesize about how you might be able to sort a mixed population of cells into prokaryotes and eukaryotes. Try to be practical‚ build on your understanding of the differences between the two cell classes. My best idea would be to sort them based on size since the eukaryote cells are smaller in size and the prokaryote cells are larger in size and shape. Another way

Bio 93 Review Sheet: 1. Understand all the THEMES presented in the introductory lecture (lec 1). 2. What is an open system? Energy in and out‚ comes in and leaves as heat 3. What are the 4 most important elements in the human body? C‚ O‚ N‚ H 4. Draw the periodic square for Helium. How many valence electrons does it have? How do you figure this out using the periodic table? Two valence e-‚ 23He‚ all the way right full shell only holds two electrons 5. What is an isotope? How are they used

newly transcribed rRNA bound to ribosomal proteins‚ while the GC‚ contains rRNA bound to ribosomal proteins that are beginning to assemble into ribosomes. However‚ it has been proposed that this particular organization is only observed in higher eukaryotes and that it evolved from a bipartite organization with the transition from anamniotes to amniotes. Reflecting the substantial increase in the DNA intergenic region‚ an original fibrillar component would have separated into the FC and the DFC. Another

membrane. It is worth noting that some cells also have hair-like cilia on the surface‚ or long whip-like flagella at one end. Besides‚ she introduces briefly about the differences between Prokaryotes and Eukaryotes as well. Prokaryotes have a cell membrane and cytoplasm and no other organelles. Eukaryotes have a number of different cell organelles. After that‚ she begins to go into the details about the cell organelles. Organelles are sub-cellular structures that provide internal compartmentalization

There are tow major types of cells‚ prokaryotic cells and eukaryotic cells. An organelle is defined as an internal‚ membrane bound sac or compartment that serves one or more functions inside the cell. Generally‚ cell organelles are found more in eukaryotes compared to prokaryotes. One of the main advantages of partitioning the cell interior with these cell organelles is that numerous activities can occur simultaneously in a very confined space. There are different numbers and variation of organelle

if they are asexual or sexual‚ the number of offspring they can have‚ and the adaptations they have made. The cheetah is in the “Animalia kingdom “‚classified as mammalia ‚and its order is carnivora. Cheetahs have a type of cell that is called “Eukaryotes”. The structure of a cheetah starts off normal at the atom. Then the next stage is molecule formation. After this the organelle begins to form which constructs the cell. The cells will start to create
