Answers
Explanation:
A scanning electron microscope (SEM) directly produces an image of the three-dimensional structure of the surface of a specimen. The SEM is usually a smaller, simpler, and cheaper device than a transmission electron microscope
Answer:
electron microscope.
The functioning of a unicellular organism is not as complex as a multicellular organism.
Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments. Pseudopods are used for motility and ingestion. They are often found in amoebas
A cell wall is a ridgid, protective layer and it covers the cell membrane. For plants, cell walls are mainly made up of cellulose, while a cell wall in bacteria is made up of peptidoglycan
