are lysosomes found in all cells?
448759
Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.

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.

Cell biology authorities differ on this. ... The organelles include the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes, mitochondria whereas cell membrane is a protective layer around the cell, covering all the major organelles within, providing the cell its shape and its volume.

Golgi Apparatus. Quick look: Golgi apparatus(or complex, or body, or 'the 'Golgi') is found in all plant and animal cells and is the term given to groups of flattened disc-like structures located close to the endoplasmic reticulum. ... Destination 1: within the cell, to organelles called lysosomes.

Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label.

Lysosomes are digestive bags of the cell and Plastid is a cell organelle which contains chloroplast and leucoplast which give colour to the plant.
1393382
Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.
92942
Ribosomes are found in prokaryotic and eukaryotic cells; in mitochondria, chloroplasts and bacteria.

As these organelles are present only in animal cell, vesicle function in this case will be different compared to that of plant cell. The lysosome structure consists of small sacs that are bound by a single layered membrane. These are the organelles that are involved with cellular digestion.

Bacterial cells do not have any membrane bound organelles, so no lysosomes. ... Bacteria secrete enzymes to break down molecules in the media surrounding them and then they absorb the products. This is why some bacteria are important decomposers in the same way that fungus are.
1298258
The primary sites of intracellular digestion are organelles known as the lysosomes, which are membrane-bounded compartments containing a variety of hydrolytic enzymes.
1147013
Types of Lysosomes There are two main types, these include: Primary lysosomes - are formed from Golgi apparatus appearing as small vesicles. ... Compared to primary lysosomes, secondary are larger in size and capable of releasing their content (enzymes) outside the cells where they degrade foreign material.
174355
What is the difference between a lysosome and lysozymes? ... Lysosome is part of cell organelle that has digestive enzymes which digestes worn out organelles , food particles, viruses etc. While lysozymes are capable of breaking bonds outside the cell wall of bacteria.

There are many ways that peroxisomes are similar to lysosomes. They are small vesicles found around the cell. They have a single membrane that contains digestive enzymes for breaking down toxic materials in the cell. They differ from lysosomes in the type of enzyme they hold.
721490
Ribosomes are found in two locations in the cell. Free ribosomes are dispersed throughout the cytoplasm. Bound ribosomes are attached to a membranous structure called the endoplasmic reticulum. Most cell proteins are made by the free ribosomes.
695398
The basic structure of cell consist of nucleus, plasma membrane and cytoplasm. Other than this different structures like Endoplasmic Reticulum(ER), Golgi body, Lysosomes, Mitochondria, Plastids and Vacuoles are also present. All of these are cell organelles.

Vesicles are found in different kinds of cells, like archaea, bacteria, and plant and animal cells. The vesicles found in these different cells have different functions, and one cell can have various types of vesicles, which have different roles.
