Organelle. Function. Flagella. Whip/tail-like structure that helps propel the cell forward. Cilia. Short, hair-like structure that surround the cell and help it move. Pseudopodia. Extension of cytoplasm into the cell membrane that allows the cell to “crawl”. Image modified from OpenStax College, Biology, CC BY 4.0.
- is a Flagella found in both prokaryotic and Eukaryota cell and same goes for cilliaYes, Flagella is found in both prokaryotic cells and Eukaryota cell. For example- Bacteria have flagella:Prokaryotic cells Euglena have flagella: E...
- what are the difference between plants and animal cellsplant cells tend to have all the features of an animal cell: mitochondria, nucleus, cytoplasm, ribosomes and cell membrane. But plants also have a...
- Which cells have cell walls?Plant cells, algae, fungi and in all of the prokaryotes with the exception of the mollicute bacteria. Hope this helps!
- How do ribosomes make proteins?There are a few pages and videos on this process here on Khan Academy, it is called translation. Start here, then see the other things in that play...
- Why are atoms non-living things?An atom is not a living thing because it does not share the seven characteristics of living things which are: order, sensitivity or response to the...
- are cells and atoms the same size or cells are smaller or bigger then them?Cells are much larger than atoms. Atoms are the basic building block of all matter; cells are the basic unit of life.
- what does the cell wall help for?It helps with providing a rigid and stiff structure to support and protect cells. Isn't apparent in all cells.
- are cells and atoms the same?Atoms are just materials which combined makes molecules , they are mostly non - living but cells are living beings
- Are cells bigger than atoms? Are there atoms on cells?Yes and yes!! Atoms are smaller than cells and they make up cells.

Neurons lie adjacent to each other but are not connected. There is a tiny gap between neurons called a synapse. The function of a neuron is to transmit nerve impulses along the length of an individual neuron and across the synapse into the next neuron. The electrical signals transmitted by neurons are called action potentials. The electrical signal...
The neuron contains the soma (cell body), which extends the axon (a nerve fiber conducting electrical impulses away from the soma), and dendrites (tree-like structures that receive signals from other neurons). The myelin sheathis an insulating layer that forms around the axon and allows nerve impulses to transmit more rapidly along the axon. Neuron...
Although there are billions of neurons and vast variations, neurons can be classified into three basic groups depending on their function: sensory neurons (long dendrites and short axons), motor neurons (short dendrites and long axons), and relay neurons (short dendrites and short or long axons).

Structure of Twaron and Kevlar. The aromatic rings appear as hexagons. The rings are attached alternately to either two NH groups or two CO groups. The attachment points on each ring are diametrically opposite each other, meaning this is classed as a para -aramid. The term aramid is shortened from aromatic polyamide.

Aug 14, 2020 · However, all cells have three main parts, the plasma membrane, the cytoplasm and the nucleus. The plasma membrane (often called the cell membrane) is a thin flexible barrier that separates the inside of the cell from the environment outside the cell and regulates what can pass in and out of the cell.
The development includes the process of cell differentiation, in which unspecialized cells become specialized in structure and function to perform certain tasks in the body. The development also includes the processes of growth and repair, both of which involve cell differentiation. Growth is the increase in body size.
All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts. Cells contain parts called organelles. Each organelle carries out a specific function in the cell.
