Cell Structure
The knowledge and concept about the structure of the cells have changed constantly over the past years. Primarily the scientist defines the cells as a simple membranous sac with fluids and some particles. Researches have now revealed that the cell is the more complex and basic unit of life. There are different types of cells and they also differ in shape and structure. The basic three parts of a cell are cell membrane, cytoplasm, and organelle.
Plant Cell
The smallest functional unit of a living organism is known as the cell. It is composed of cytoplasm enclosed by an outer layer known as the cell membrane. A cell is classified as a prokaryotic cell and a eukaryotic cell. A prokaryotic cell does not contain a nucleus, and the genetic material is freely suspended in the cell cytoplasm; for example, bacteria are composed of a prokaryotic cell. Whereas a eukaryotic cell contains a nucleus and membrane-bound cell organelles with a specific function, plants and animal cells are examples of eukaryotic cells.
Plant Cell Types
Plants are made up of a variety of cell types that include both living and dead cells. These cells provide them mechanical and structural support along with the growth of plants. Plant tissue is a group or collection of cells, which are similar in structure and work together to accomplish a specific function. Plant cells are most similar to animal cells, both being eukaryotic cells.
Create a diagram or model on cytoplasm. And then answer these questions on a biological perspective. Thanks!!
- What advantages and disadvantages are there to an all brain/all muscle body plan?
- Would this organism benefit from specialized tissues? Why or why not?
- Consider actual organisms that may be similar in nature with a limited number of specialized tissues/cells. Would you be worried about this organism causing global extinction? Why or why not?
- Why do you think that the biologist consultant who worked on this film chose an organism which has uniformity in the tissues?
- Imagine a re-make of this movie. What organism would you suggest to the producers would make the optimal Martian in this movie? Defend your proposal using knowledge of cell structure and function.
Each cell is filled with a viscous fluid called the cytoplasm, which is encased in the cell membrane. It mostly consists of proteins, salts, and water. All the internal and external components of eukaryotic cells are contained in the cytoplasm. The cytoplasm houses all the organelles found in eukaryotic cells, including the nucleus, endoplasmic reticulum, and mitochondria. The cytosol is the part of the cytoplasm that is not housed in an organelle. Contrary to appearances, the cytoplasm is highly structured while appearing to lack any form or organization. The cytoskeleton, a network of protein scaffolds, is responsible for giving the cell and its cytoplasm its structural integrity.
