Microbial cells are grouped into two major groups based on the separation of their genetic material from the cytoplasm. Which are these two groups?

Answers

Answer:

Eukaryotic microbes and prokaryotic microbes

Explanation:

Some microbes such as bacteria do not have a membrane-bound nucleus. So, their genetic material lies in the cytoplasm itself. These microbes are called prokaryotic microbes. All the bacterial species are prokaryotes. Example: E. coli.

On the other hand, some microbes have a well define nucleus to house their genetic material. These microbes are called eukaryotic microbes. Fungi and protists are the eukaryotic microbes. Example: plasmodium and slime mold.

A student is examining leaf cells. Which organelle is most likely to be missing from the cells?

Answers

The organelle which is most likely to be missing from leaf cells is Lysosomes.

Lysosomes are an important organelle for eukaryotic animal cells as they contain the digestive enzymes. The macromolecules or foreign matter which are harmful for the cells enter the animal cells easily but not the plant cells as the plant cells contain cell walls.  Phagocytosis or digestion of macromolecules is not much needed in plant cells so a lysosome can be missing from the leaf cell.

A cell is the most basic form oflife. It is what most of the organisms are made off. For the organism tofunction, the cell must also function. It has organelles too that helpsfunctions what the microorganisms need. A leaf cell contains chloroplasts thatanimal cells and other cells do not have.  The chloroplast is where the photosynthesishappens. It needs sunlight for the process of photosynthesis. Notice that theleaf has a broader surface area to enable them to be exposed to the sun.

Diffusion can be defined as active transport of particles up a concentration gradient.


movement through a cell membrane using energy from ATP


movement of particles from a region of high concentration to a reaigon of low conentration



movement of particles from a region of low concentration to a regoin or to a high region

Answers

Answer:

Option (3).

Explanation:

The molecules may transport from inside and outside of the cell from their region of low concentration to high concentration or vice-versa. Different types of transport process are diffusion, osmosis, primary active transport.

Diffusion occurs naturally in the organism and no energy is required for its transport. The molecules move to the region of lower concentration from its region of higher concentration. The molecules moves along the concentration gradient.

Thus, the correct answer is option (3).

movement of particles from a region of a high concentration to a region of low concentration
