1. (3 pts) Describe the chemical structure of the plant cell wall and plant cell membrane. Make sure to include whether each structure is hydrophobic or hydrophilic. The plant cell wall contains cellulose and the membrane contains phospholipids.…
* In addition to many layers of peptidoglycan, the cell wall of Gram-positive bacterials cells also contain:…
Their sturdy cell wall, however, counteracts this osmotic pressure, keeping too much water from rushing in. (Eukaryotic cells are protected from osmotic pressure by the cholesterol in their cell membrane.) What makes the bacterial cell wall rigid is the molecule peptidoglycan, a polymer made of sugars and amino acids that link to form a chainlike sheath around the cell. Different bacterial walls can have different structures, but all have peptidoglycan, which is found only in bacteria. By interfering with the synthesis of CELL WALL…
1.) In the structure of a eukaryotic plant cell consist of a membrane-closed nuclei and organelles, since they developed a process in which they manufacture their own food. The Chlorophyll, which gives the plant the green color captures sunlight to convert water and carbon dioxide into glucose and carbs, in which are used for the repetition of the cycle. Not only does the plant cell consist of a membrane, unlike other eukaryotic cells it additionally has a cell wall in since it has a much bigger central vacuole. They also have plasmodesmata, and chloroplast only found in plant cells. A nonphotosynthetic prokaryotic cell would differ from a generalized eukaryotic plant cell by the presence of a nucleus and the structures of the cell. Plants do not have bones structural strength besides the membrane, also the vacuoles contain nutrients and liquids and the chloroplasts contain the organelles that help the plant to get energy form the sunlight. A prokaryotic cell usually gets its energy from sugars and other organic substances and they have a cytoskeleton like cilia.…
The cell wall creates a protection and barrier for the cell and creates its shape , just like the kingdom walls protect the people inside of it from attacks and dangerous people…
1. Cell wall – Provides support and protection and is responsible for giving plant cells their shape.…
The thick layer around each cell is the cell wall, a rigid layer outside the cell membrane that gives the cell structure and support. Its present indicates that the cell is either a prokaryote or plant cell. The small green organelles within each cell are chloroplasts. Chloroplasts facilitate photosynthesis and are only found in plant cells; thus their presence confirms that the cell is a plant cell.…
A plant cell has a cell wall and a cell membrane while a animal cell has just a cell membrane.…
8.) Prokaryotic cell walls are constructed of many layers, which is formed from peptidoglycan polymers cross-linked by peptide side chains.…
Made of cellulose which forms very thin fibers, strong and rigid, found in plant cells, protect and support the enclosed substances (protoplasm), resist entry of excess water into the cell, give shape to the cell…
All three of the above mentioned genera are considered to be members of the Prokaryotic cell family which includes bacteria. They have certain identifiable features that distinguishes them from Eukaryotes such as: “Their DNA is not enclosed within a membrane” and “they usually divide by binary fusion, organelles are not encompassed within the membrane and the cell walls usually consist of complex polysaccharides peptidoglycan” (Tortora, 2013).…
As well as centrioles which help organize cells Short Answer Questions 1. Compare and contrast the structure and function of the cell wall with that of the cell membrane. Compare: Both provide protection and support for the cell Contrast: Wall found only in plants, fungi and algae. Usually rigid and lies on the outside of the membrane, membrane is soft and flexible made of a lipid bilayer. 2.…
There are many parts to a cell. The capsule, only found in specific bacteria, is the outermost protective coating. The cell wall gives the cell its shape. It is made out of peptoglycan. The cytoplasm is the gel-like material that fills up the cell. Here is also where the organelles are found. The Flagella helps the bacterium to move. I swings it in a propeller motion. The pili are hair-like organelle that helps the bacterium to attach to other cells or items. The nucleoid is where the DNA and RNA is stored.…
What could you determine about a specimen if you observed a slide image showing the specimen with a cell wall, but no nucleus or mitochondria?…
There are two different types of cells, there are prokaryotes and eukaryotes. Within eukaryotes there are different structures and similar structures. For example; in a plant cell they have a nucleus, mitochondria an ER, and a Golgi body. These are the same as animal cells; however they differ because plants cells have a cellulose cell wall, chloroplasts, large central vacuole and they use starch for storage whereas an animal cell has lysosomes, rough ER, smooth ER and ribosomes. Eukaryotes differ from prokaryotes because prokaryotes have no nucleus, they just have a loop of DNA and they also have no membrane-bound organelles. Prokaryotes also have a cell wall, along with a slime capsule, flagellae and plasmids.…
