What is an organelle that is composed of two short microtubules at right angles to each other?
(: Centriole :)
Are vertical angles adjacent angles?
No vertical angles are across from each other & adjacent angles are beside but opposite from each other.
How many angles and how many right angles in a square?
4 right angles, no other angles.
Angles across from each other equal to each other?
Vertical Angles
Angles that are next to each other?
adjacent angles

Organelle composed of two short microtubules at tight angles to each other has active role in mitosis?
centriole
What structures make up the fibers of the mitotic spindle?
The mitotic spindle is composed of microtubules, which are dynamic structures made up of tubulin protein subunits. It consists of three main types of microtubules: kinetochore microtubules that attach to the chromosomes, polar microtubules that interact with each other to help push the poles of the cell apart, and astral microtubules that anchor the spindle poles to the cell membrane.
What are cilia and flagella made up of?
Cilia and flagella are made up of microtubules, specifically arranged in a 9+2 pattern. They consist of nine doublets of microtubules surrounding a central pair of microtubules. The movement of cilia and flagella is generated by the sliding of these microtubules past each other.
What organelle is made up of microtubules and microfilaments?
Only the plasma membrane is made of phosophlipids as a semipermiable membrane. No other structures are made from it. There are, however, organelles which are surrounded by a plasma membrane. These include nucleus, mitochondria, peroxisomes, lysosomes and chloroplasts (in plants).
How do microfilaments and microtubules differ from each other?
Microfilaments are thinner rods of protein that enable movement. Microtubules are hollow tubes that give rigidity and shape. Flagella and cilia have microtubules in their centers.
What motor molecule is associated with the microtubules in cilia and flagella?
Dynein is the motor molecule associated with the microtubules in cilia and flagella. Dynein is responsible for generating movement by sliding the microtubules past each other.
Do centrioles lie at right angles in a cell?
Yes, centrioles typically lie at right angles to each other within a cell, forming a structure known as a centrosome. This orientation is important for organizing the microtubules during cell division and maintaining cell structure.
What other structures of the cytoskeleton would show the same pattern of microtubules as a flagellum?
Cilia, which are similar to flagella in structure, would also show the same pattern of microtubules. Both flagella and cilia contain a 9+2 arrangement of microtubules, with nine outer doublet microtubules and a central pair of microtubules.
Which organelles are not surounded by a membrane?
Ribosomes and centrioles are organelles that are not surrounded by a membrane. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
How could you distinguish an organelle that originated as a bungled feeding attempt from an organelle that originated as invading parasite?
One organelle will have endosymbionts. While on the other hand, the other organelle will have apicoplast. That is how one can differentiate them.
What is the flagellum made up of?
The flagellum is composed of a motor that drives the rotation of the whip-like structure, known as the filament or flagellar filament. It also contains a hook that connects the filament to the motor, as well as other structural components like the basal body and various proteins for support and movement.
