ADI Lab How should the unknown organisms be classified? Using previous knowledge from tenth grade biology, we know the variation between plant and animal cells. The differences are within the organelles. Animal cells have centrioles, lysosomes.
1a. What is a cell? A cell is the basic unit of life. 1b.
There are protozoal, anthropod , helminths, bacterial, and viral. Protozoa are one-celled organisms, they can multiply in the human body which allows them survival and permits serious infections to develop from just a single organism. An arthropod is an invertabrate having a skeleton, a segmented body and jointed appendages and they are larger than protozoa for example lice, ticks. Helminths are known as parasitic worms, are large multicellular organisms, which when mature can generally be seen with the naked eye. They are often referred to as intestinal worms even though not all helminths reside in the intestines.
Organelles as organism is from The Lives of a cell authored by Lewis Thomas. Thomas uses a unique writing style that is very recognizable and different from the others. This helps us to appreciate our diversity as human beings demonstrated by our abilities to write differently. As a reader one is able to form an image of who Thomas is by how he expresses his feelings and attitudes. When this text was written a lot of people, mostly scientists, thought and had knowledge of different things than they do now.
Even though we cannot see cells without a microscope, they are the basic unit of life and they exhibit all of the characteristics of living organisms. They can exist individually, as do bacteria, or they may work together, taking on specialized tasks to create a more complex organism. However, all living organisms share certain characteristics, which are discussed below. Cells are made of cytoplasm.
Elijah Brycth B. Jarlos IX-Argon 1. Multicellularity is a condition of an organism to have multicellular cells. An example of a organism who has multicellular cells are plants, animals, and humans. The main reason of why scientists have a hard time finding a good set of existing organisms to compare. Is neither the first set of organisms which is being compared is dying as fast as the second specimen is being examined or they just can’t find the right species.
These cells are known as HeLa. HeLa cells contributed lots of scientific knowledge, but were also a curse to the Lacks family. Key Idea 1: The Anatomy of Cells Today, science textbooks everywhere are filled with the anatomy and structure of cells. We can credit much of this knowledge to HeLa.
Biology, the study of life and living organisms, is complex and encompasses a multitude of theories and ideas. In AP Biology, the first unit covered was evolution. Chapters 29, 31, 39, 40, 41, 42, and 43 in the textbook, Campbell’s Biology in Focus, not only discusses the four main ideas of biology: evolution, energy, information, and systems, but it also gives examples of each in order to help guide the reader’s understanding of the concepts. The first big idea of AP Biology is: “the process of evolution drives the diversity and unity of life.” Chapter 39 in the textbook encompasses this main idea through discussing natural selection and genetic diversity.
Again, humans are shown to be connected to the animal kingdom through the evidence of like genes in creatures that do not in anyway resemble the human
Lastly they are both in common because they are both in living things and they both create different kinds of tissues. Even though Plant and Animal cells can be very alike they are also very different in a lot of ways. For example
Our body is one of the most astounding things on earth. We have an innumerable amount of cells that are aimed to carry out operations with absolute accuracy. Researching deeper into the complex organism, which is our body is something I would enjoy doing as a career. My fascination for cells and our physiology are developed through my subjects.
The human cells have a few options: they can be
About 85% of all animals on the planet are part of the scientific group called Arthropods. Some Arthropods are shrimp, crayfish, krill, barnacles, scorpions, spiders, insects, centipedes, mites, ticks, lobsters and crabs. You can tell that an animal is an arthropod because all arthropods have more than one body segment , a body segment is a body part like the abdomen like a whale for example a whale has one solid body that is not split into separate parts. This means that they have a body made up of more than one section, flies have three separate body sections . Another way you can separate animals and arthropods is that they can have many legs the average spider has six legs and a millipede has lots of legs up to thousands!
The cell itself was first discovered by Robert Hook, an English scientist, in 1665. The theory itself is made up of ideas and conclusions drawn out from the various scientists including Theodore Schwann and Matthias Schleiden who proposed the theory in 1839. Rudolf Virchow also played a part in the development of the cell theory and through the years, with additions of new specifications and redefined parts of the theory, it became more modernised. The general basis of the theory is that all organisms are composed of one or more cells. In further detail, the theory proposes that 1) all living cells arise from pre-existing cells as a result of division, 2) cells are the fundamental unit of structure and function in living organism, 3) the activity
There are millions of these cells inside the human body, and each has a different type of responsibility, or function. There are an infinite amount of cell types, and a few examples of these types are: 1) muscle cells, 2) nerve
