What else can I help you with?
What cell has no mitochondria?
Prokariyotes lack a nucleus.Mamalian erythrocytes,seive tube elements also lack.
Which type of eukaryotic cells lacks nucleus?
Mammalian red blood cells lack a nucleus.Seive tube elements lack a nucleus.
What cells have no mitochondria?
prokariyotes do not have.Mamalian RBC,sieve tube elements and some protists lack them
Which tissues lack mitochondria?
There are cells without mitochondria.Some are erithrocytes,seive tube elements etc
Will a breakage in the output tube of the brake master cylinder of a Stewart and stevenson tow truck create total lost of brakes?
Yes, it can lead to a lack of brake fluid or a lack of braking pressure.
Does a eukaryotic cell have a necleus?
Typical eukariyotes have a nucleus.But red blood cells of mammals,seive tube elements lack a nucleus.
Why is ftm typically pink at the top and colorless in the middle and bottom of the tube?
The pink color at the top of a tube of blood collected in a FTM tube is due to a stabilizing gel present in the tube. The gel helps separate the serum or plasma from the blood cells. The lack of color in the middle and bottom of the tube is because the blood cells settle to the bottom due to their higher density, leaving the serum or plasma above them.
Do all eukaryotes possess mitochondria?
Almost every eukaryotic cell have them.But mammalian red blood cells,sieve tube elements lack them
Do sieve tube have chloroplast?
Sieve tube elements, which are part of the phloem in plants, do not contain chloroplasts. Instead, they are responsible for transporting sugars and nutrients throughout the plant. While they lack chloroplasts, companion cells, which are closely associated with sieve tube elements, do contain chloroplasts and provide the necessary metabolic support for the sieve tubes.
Does a brittle star have tube feet?
Brittle stars do not have tube feet like sea stars. Instead, they possess flexible, slender arms that can move independently and are lined with small spines. While they lack the suction capability of tube feet, brittle stars can use their arms for locomotion and feeding. Their tube-like structures, called podia, are primarily used for respiration rather than movement.
Why does liquid not rise in ordinary glass tube?
Liquid does not rise in an ordinary glass tube due to the lack of sufficient adhesive forces between the liquid molecules and the glass. Unlike capillary action, which occurs in narrow tubes where the adhesive forces between the liquid and the tube's surface exceed the cohesive forces within the liquid, an ordinary glass tube may not create the necessary conditions for this effect. As a result, the liquid remains at a stable level rather than rising in the tube.
Why sieve tube lack nuclus?
Sieve tube elements lack a nucleus to facilitate the efficient transport of sugars and other organic nutrients in plants. By losing their nuclei and other organelles, these cells can maximize their internal space for the flow of sap, ensuring effective and uninterrupted movement of substances throughout the plant. This adaptation is essential for the functioning of the phloem, allowing it to maintain continuous nutrient transport even as the plant grows and develops.
