Do prokaryotes have plasmids?
Some prokaryotes also carry smaller circles of DNA called plasmids. The genetic information on the plasmids is transferrable between cells, allowing prokaryotes to share such abilities as antibiotic resistance. Humans have discovered that prokaryotic plasmids can be genetically engineered.
Do animal cells have lysosomes?
Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.
Is lysosome in plant and animal cells?
Lysosomes are membrane bounded organelles found in animal and plant cells. They vary in shape, size and number per cell and appear to operate with slight differences in cells of yeast, higher plants and mammals.
Which of the following is a feature of prokaryotic cells but not eukaryotic cells?
Explanation: Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.
How do prokaryotic cells differ from eukaryotic cell?
Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago. The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

A lysosome (/ˈlaɪsəˌsoʊm/) is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins, and its lumenal proteins.
Where are lysosomes found in the cell?
Lysosomes are found in all animal cells, but are rarely found within plant cells due to the tough cell wall surrounding a plant cell that keeps out foreign substances.
Where are lysosomes produced in the cell?
Lysosome enzymes are made by proteins from the endoplasmic reticulum and enclosed within vesicles by the Golgi apparatus. Lysosomes are formed by budding from the Golgi complex.
Are plasmids found in eukaryotes or prokaryotes?

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell’s chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.
Why do macrophages contain many lysosomes?
Macrophages contain abundant secretory lysosomes and utilize them to exert their innate immune functions. Through the exocytosis of secretory lysosomes, they can secrete not only lysosomal enzymes but also antimicrobial proteins and several cytokines.
Are lysosomes found in photosynthetic cells?
These figures show the major organelles and other cell components of (a) a typical animal cell and (b) a typical eukaryotic plant cell. The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole”structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
Do bacteria cells have lysosomes?
many membrane bound organelles- lysosomes, mitochondria (with small ribosomes), golgi bodies, endoplasmic reticulum, nucleus. Large ribosomes in cytoplasm and on rough ER. genetic information- DNA is in the cytoplasm and is organized into the bacterial chromosome and into plasmids. There is mRNA, tRNA and rRNA.
In which cell lysosomes are absent?
Lysosomes are absent in red blood cells.
Why lysosomes are present in only animal cell?
Lysosomes are found in nearly every animal-like eukaryotic cell. They are so common in animal cells because, when animal cells take in or absorb food, they need the enzymes found in lysosomes in order to digest and use the food for energy. On the other hand, lysosomes are not commonly-found in plant cells.
Why are there no lysosomes in plant cells?
Lysosomes are not needed in plant cells because they have cell walls that are tough enough to keep the large/foreign substances that lysosomes would usually digest out of the cell.
Which of the following does a prokaryotic cell have that an animal cell does not?
When comparing prokaryotes to eukaryotes, the main fact to remember is that prokaryotes do not contain membrane-bound organelles. This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region.
Do prokaryotes and eukaryotes have cytoplasm?
All prokaryote and eukaryote cells also have cytoplasm (or cytosol), a semiliquid substance that composes the volume of a cell. Essentially, cytoplasm is the gel-like material enclosed by the plasma membrane.
Which is a typical function of lysosomes?
Which is a typical function of lysosomes? BREAKDOWN of damaged organelles, such as chloroplasts. Lysosomes do break down damaged organelles; lysosomes are rarely found in plant cells.
What do only prokaryotic cells have?
All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles.
What do prokaryotic cells have?
Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.
