Bacteria, archaea, eukaryote 9. Name the 4 groups/kingdomes in the domain Eukarya and give characteristics of each based on feeding habits and the number of cells they are made up of. Protista, plantae, fungi, animalia 10. What are 4-5 characteristics that help to separate humans from other living organisms? *
What is the difference between prokaryotic cells and eukaryotic cells? What are the names for the two major groups of prokaryotes? both have a cell membrance on the outside and both have ribosomes but the eucaryotic only have membrane bound organelles. both can have the cell wal. euc.
1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons. The cotyledons of eudicots supply nutrients for seedlings, but the cotyledons of monocots store some nutrients and act as a transfer tissue for nutrients stored elsewhere. Five key features are typically used to distinguish monocots from eudicots; a seed, arrangement of vascular tissue in roots, stems, and leaves, and number of flower parts. The seed has the reproductive structures that are protected from drying out, have male and female gametophytes which are reduced in size. In young dicot stems and stems (usually the upright, vertical portion of a plant transports substances to and the leaves) that do not increase in thickness, xylem and phloem are arranged in vascular bundles in the cortex.
5. Distinguish between animal and plant cells – structures in common/ structures unique to each. 6. Where is DNA located in a prokaryote cell? In a eukaryote cell?
All viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Fungi are diverse in terms of their shape, size & means of infecting humans. Fungi are eukaryotes, meaning that like parasites, their cells have a true nucleus and complex internal structures. They are most commonly found as environmentally resistant spores and molds, but can cause disease in humans in the forms of yeasts. Parasites are part of a large group of organisms called eukaryotes.
Fungi Unlike bacteria and viruses, fungi are simple plant-like organisms which reproduce using spores. There are three types of fungal infections; ones which occur on the surface of the skin and hair; those which occur in the epidermis (such as ringworm and athlete's foot) and those which affect the deeper layers of skin – the dermis, subcutaneous tissue, muscle and fascia. Fungi may reach these layers as a result of penetrating wounds, or may be inhaled. Parasites Parasites differ from bacteria in that they need a living host to survive and reproduce, although not all parasites affect the host. Parasites can be acquired through contact with a contaminated surface, via infected water or food and through contact with contaminated bodily fluids such as blood, faecal matter and sexual contact.
Parasites are larger than bacteria, their cells contain a nucleus and share features with human cells. Some parasites replicate in the environment and some can only replicate within a host organism. Fungi are diverse in their shape and size, their cells have a nucleus and complex internal structures, they are found as environmentally resistant spores and molds and can cause disease in the form of yeasts. 2. Common illnesses and infections caused by bacteria, viruses, fungi And parasites: Bacteria Tuberculosis, pneumonia, tetanus, typhoid fever, diphtheria, salmonella.
They thus contain only half of the genetic material common to the animal's cells and have not yet undergone any development. 3. Removal of Egg's Nucleus As the genetic material that is present in the egg cells is not what scientists want the cloned animal to have, and as having multiple nuclei in the same cell can cause many problems for the cloning process, scientists must extract the egg cell's nucleus. They do this through a method similar to the method used to isolate the donor cell's nucleus, only they discard the egg's
Fungi are Eukaryotes, when compared to prokaryotic. Fungi are eukaryotic multicellular organisms. Fungi cells have a cell wall that contains chitins, but the wall
3. There are two types of research methods used in developmental research; they are ________________ and _______ _______________ designs. 4. Define or describe the 3 types of attachment: a. Secure b. Ambivalent c. Avoidant 5.
