Each cell in the respiratory epithelium has around 200 motile cilia. [12] In the reproductive tract, smooth muscle contractions help the beating of the cilia in moving the egg cell from the ovary to the uterus. [13] [15] In the ventricles of the brain ciliated ependymal cells circulate the cerebrospinal fluid.
The cell then divides in two, and each new cell obtains a copy of the micronucleus and the macronucleus. Ciliate undergoing the last processes of binary fission Division of ciliate Colpidium Typically, the cell is divided transversally, with the anterior half of the ciliate (the proter ) forming one new organism, and the posterior half (the ...
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Cilia Structure. Primary cilia are found to be formed when a cell exits the cell cycle. [2] Cilia consist of four main compartments: the basal body at the base, the transition zone, the axenome which is an arrangement of nine doublet microtubules and considered to be the core of the cilium, and the ciliary membrane.

Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to some extent here. [7]
They are membranous, ovate, 4–5 mm (0.16–0.20 in) long, and 5-veined. The palea have 2-veined, ciliated keels while the fertile lemma is keelless, lanceolate, with an acute apex and ciliated margins. The lemma is 4.5–5 mm (0.18–0.20 in) long with 7–9 veins. The flowers are fleshy, oblong, truncate, with two lodicules and three anthers.
At the end of ovulation in February, the para recta contain very few ciliated cells and a large number of glandular cells. The pars convolute contains secretory, goblet, and ciliated cells, and the par utera only has one type of glandular cell. The epithelial mucosa is more secretory at this time, and there is a greater abundance of cilia cells ...
