A) Prokaryotic cell b) Animal cell c) Plant cell • Click “continue” and answer the “Pop-up Questions.” When you are finished‚ click on “Plant cell” and read the text. 4) Which organelle in the plant cell would mainly help the cell take in water or get rid of water‚ just like the potato did? This is also known as “osmosis.” How do you know that this organelle would
Premium Eukaryote Organelle Mitochondrion
These cells contain several organelles suited to a specific function they carry out within the cell. These eukaryotic cells contain a Nucleus‚ Mitochondria‚ Ribosomes‚ Rough and Smooth endoplasmic reticulum‚ Golgi apparatus and various other organelles. Most of the organelles are separated from each other by a membrane‚ these membranes are based on lipid bilayers that are similar to each other. The organelles membrane is there to keep the contents of each organelle separate from the rest of this

us one good reason why the cytoskeleton is not the most important organelle….. that’s what I thought. WHat do these 3 parts do? Microtubules- are hollow tubes made of the protein called tubulin. This tubulin contains two different sub-units. The microtube holds all organelles in place so without this the organelles will collide with each other or float around randomly. The microtubules also act as tracks for the organelles to move. Microfilaments- are long threads of the protein actin which

source of energy‚ produced by an organelle called the mitochondria. An organelle is basically a cell within a cell that performs a specialized function. These organelles produce chemical energy‚ but also are a major factor in understanding the evolution of eukaryotic cells. Although there are many differences between eukaryotic cells and prokaryotic cells in size‚ complexity‚ and internal components; there is a similarity between prokaryotic cells and the organelles of eukaryotic cells. The complex

chloroplast is most commonly recognized for its vital role in plant cells & protist cells as their main provider of energy. Within this review we are going to discuss what exactly is chloroplast what structures make up this complex & super efficient organelle which is so important not only to plants & protists‚ but also to us. How exactly does it absorb and use solar energy and use it to produce carbohydrates rich with energy that can be passed down the food chain‚ supplying even us with a great energy

of bacteria (both in their size and their having a circular form). * DNA sequence analysis and phylogenetic estimates suggest that nuclear DNA contains genes that probably came from plastids. * These organelles’ ribosomes are like those found in bacteria (70S). * Proteins of organelle origin‚ like those of bacteria‚ use N-formylmethionine as the initiating amino acid. * Much of the internal structure and biochemistry of plastids‚ for instance the presence of thylakoids and particular chlorophylls

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan
