What are sulci and gyri?
Sulci are the shallow grooves or furrows on the surface of the brain, while gyri are the raised ridges between these grooves. Together, they increase the surface area of the brain, allowing for more complex cognitive processing and functions.
What machine makes small furrows and sows seeds in them?
A seed drill is a machine used to sow seeds at a precise depth and spacing by making small furrows in the soil and then placing seeds in them. This helps to optimize seed germination and growth by ensuring the seeds are planted at the correct depth and distance from each other.
The process of mitosis is the same in plant and animal cells until the division of the cytoplasm. At this stage plant cells develop . cleavage furrows cell plates centromeres?
At the stage of cytokinesis during mitosis, plant cells develop cell plates, while animal cells form cleavage furrows. The cell plate is formed by vesicles that fuse at the center of the dividing cell, eventually leading to the formation of a new cell wall that separates the two daughter cells. In contrast, cleavage furrows pinch the cell membrane inward to divide the cytoplasm in animal cells. This distinction is crucial for the successful division of cells in these two types of organisms.
What affects formation of cleavage furrows?
The formation of cleavage furrows in cell division is influenced by factors such as the positioning of the mitotic spindle, the contractile ring composed of actin and myosin filaments, and signaling pathways that regulate cytoskeletal dynamics. Additionally, the presence of certain proteins and regulatory molecules, as well as cellular tension and adhesion, play important roles in determining the site and timing of cleavage furrow formation.
What are the vertical grooves in a column called?
The vertical grooves in a column are called fluting. They are decorative channels or furrows typically found running vertically along the shaft of a column.
How could the furrows your father plowed bear you what literary device is this?
This sentence uses personification, by attributing human characteristics to the furrows in the field plowed by the father. It creates a vivid image that suggests a deep connection between the father's work and the speaker's existence.
What are the ridges and the furrows of a cerebral cortex?
The ridges and furrows in the cerebral cortex are actually folds. The 'furrows' are called sulci and the 'bumps' are called gyri.
What is the furrows role?
It depends on what kind of furrow. Deep furrows are typically just a side effect of tillage operations. Medium furrows can be used for irrigation or guiding a farm implement. Shallow furrows might be used to plant seeds in, or to apply fertilizer. There are nearly as many purposes for furrows as there are types of farming.
Do microfilaments form cleavage furrows?
Yes, microfilaments are involved in forming cleavage furrows during cytokinesis in animal cells. Actin filaments assemble into a contractile ring structure that contracts to pinch the cell into two daughter cells.
What do you call the furrows of the brain?
The "furrows" are called sulcisulcus-(singular) /sul·cus/ (sul´kus) pl. sul´ci[L.] a groove, trench, or furrow; in anatomy, a general term for such a depression, especially one on the brain surface, separating the gyri.
Why do farmers make furrows?
Farmers make furrows to create rows for planting seeds or seedlings. Furrows help with drainage, soil aeration, and irrigation by channeling water to the plants' roots. They also help in weed management and provide structure for effective crop management.
What are longitudinal furrows on tongue?
Longitudinal furrows on the tongue are deep grooves that run along the length of the tongue. They are a common, benign anatomical variation that can occur naturally in some individuals and are typically harmless. If the furrows cause discomfort or concern, it is advisable to seek evaluation by a healthcare professional.
Used for making furrows or weeding?
soil, sunlight, water,
In the process of cytokinesis cleavage furrows are associated with what cell?
Animal cells!
What are the furrows of the brain called?
A sulcus is a depression or fissure in the surface of the brain.
Where are the furrows on a fingerprint located?
Furrows on a fingerprint, also known as friction ridges, are located on the surface of the skin of the fingertips. These ridges form unique patterns that help with grip and tactile sensitivity. The furrows are the valleys between the ridges, creating distinct patterns that are used in fingerprint identification. Each person's fingerprint is unique due to the variations in these patterns.
Can you give me a sentence with the word furrow?
The towering draft horse lowered its head and strained against its leather harness, powerful legs churning. The heavy plow slid forward, leaving deep furrows in the moist, dark soil.
